THE SHAKESPEARE MEMORIAL AT STRATFORD‐UPON‐AVON.

The American veneration for the birthplace of Shakespeare is well

known, and it has just taken practical shape by the presentation to

the town of a public drinking fountain and clock tower, the gift

of an American citizen, Mr. George W. Childs, of Philadelphia, in

commemoration of the jubilee of Queen Victoria. The memorial has

been erected in Rother Street, a broad open space near the center of

the town, where several thoroughfares converge, and where the annual

statute fairs or “mops” take place. The structure is handsome and

imposing, and is built of Peterhead granite (for the fountain) and

of hard freestone (for the clock tower). The base of the tower is

square, with projecting buttresses at the four corners, terminating

in acutely pointed gablets, surmounted by a lion bearing the arms of

Great Britain alternately with the American eagle and the stars and

stripes. Appropriate inscriptions are engraved on the four sides of

the memorial. The tower terminates in a spire, beneath and surrounding

which are smaller spires and turrets. The whole height of the structure

is fifty feet. The architect is Mr. Jethro A. Cossins, of Birmingham.

The ceremony of inaugurating the fountain was performed on Monday,

October 17, by Mr. Henry Irving, in the presence of the Mayor (Sir

Arthur Hodgson, K.C.M.G.), the corporation, and a distinguished

company of visitors. Sympathetic letters were read from Mr. J. Russell

Lowell and Mr. Whittier; and speeches were delivered by Mr. Irving,

by Mr. Phelps, the American Minister, Mr. Walter, of the _Times_, Sir

Theodore Martin, and others.—_London Graphic_.

[Illustration: THE SHAKESPEARE MEMORIAL AT STRATFORD‐UPON‐AVON.]

Optical Refinements in Architecture.

Many architects look upon all refinements of line and curve as so much

waste time, and would as soon think of referring to the original Latin

of Vitruvius for rules in proportioning their rooms as to consult and

apply the corrections of the Parthenon to their buildings. In sketching

out his design to a small scale on a sheet of Whatman’s drawing paper,

the architect does so without any further thought than to produce

a convenient plan or a well grouped elevation. Any infinitesimal

correction to the straight line or entasis would be inappreciable to

the naked eye on the surface of paper the inequalities of which would

render it worthless; nor does he take much trouble in the proportions

of his rooms, so long as they look right and fit well. If such

refinements are to be made, they should be shown in large drawings,

or set out to the full size on the works by proper rules and other

instruments. The task is laborious and troublesome, and contract prices

are little in sympathy with such niceties of adjustment. Even of the

more practicable mode of adopting certain ratios and proportions, the

architect does not avail himself very much.

We do not say that every horizontal beam—such as an entablature

supported by columns at intervals—ought to be “corrected” by the

application of a parabolic curve, or that every string course and

cornice should be arranged to curve or bend upward; but we contend that

these refinements ought to be made in interiors wherever the lines

are long, and contrasting lines and surfaces occur in juxtaposition;

that they are, in truth, applying precisely the same principle of

correction as the colorist or decorator would apply when he takes care

to juxtapose two colors or shades which shall be complementary to or

harmonize with each other.

It is painful to witness in modern buildings a perfect ignoring of

these principles of design. We go into a public hall or concert room,

and take our seat. The flat coffered ceiling appears to be literally

bending or falling upon our heads. To make the impression still more

apparent, the architect has introduced a circular or flatly curved arch

over the orchestral recess. If the ceiling is a flat curve, as it often

is, the trusses are, perhaps, brought down below and incased, their

lower edges being made perfectly horizontal, the two lines serving

to increase the difference between them; in other words, to make the

trusses look as if they were deflecting.

Mr. Pennethorne, some years ago, showed that the masses of the temples

of Athens and Rome were designed on perspective principles—that is

to say, the masses and many of the details were designed as they

were intended to be viewed. The point of sight was always before the

architect—that is to say, he studied the effect of his entablatures,

abaci, and other masses of details from points of view that were

likely to be frequented. It is well known that the various sections

through the Doric capitals, the mouldings, and other parts of Athenian

buildings, were composed of different arcs of the conic sections.

Mr. Pennethorne says that the Greek entablature is perspectively

proportioned and arranged to suit the given points of sight thus: The

apparent height of entablature is measured in seconds upon the arc of

a great circle. “Then, dividing this whole apparent height into some

given number of aliquot parts, measured also in seconds, the apparent

height of the architrave, of the frieze, and cornice will, in each

case, be a multiple of this given modulus. Again, by dividing the first

modulus into a given number of apparent aliquot parts, a second modulus

is obtained, by which the apparent heights of all the details of the

cornice of architrave and frieze will be regulated, and the true lineal

heights are then all determined by trigonometrical calculations.” In

short, all the visible heights of features are, upon this principle,

regulated from a given point, the real elevational height of each part

being afterward found.

This system of proportion would probably entail too much labor upon

the architect to work out with any accuracy, and may be looked upon as

chimerical. But we see instances every day of positive ignorance of

these principles, especially in the designing of mouldings, projecting

features, and towers. If the architect is too impatient to make nice

corrections in the manner we have pointed out, he ought at least to

take the trouble necessary to regulate his heights and masses before

inking in his elevations. Sketching in perspective is a valuable

auxiliary in designing roughly the masses of a building; but some more

accurate method is required in perspectively setting out the heights of

stories, entablatures, parapets, towers, and other features. This can

only be done by adjusting all heights from a given point of sight, or

upon the arc of a circle described from the said point. An elevation is

misleading, as every architect knows who has suffered disappointment

after the building is finished. It only gives vertical heights, which

may be very much curtailed or foreshortened in the actual view of the

building from the opposite side of the street, for example.

Many towers and spires have been spoiled by designing them in elevation

instead of at the angle. In broach spires we find a want of care in

one particular above the others. The broach is designed on the level.

The hips of the broach are made to look gentle in elevation, but when

raised above the eye 60 or 100 feet, they become so depressed as to

give a very ungraceful and abrupt springing to the spire.

We may instance the want of entasis to spires and columns. Every one

who has a critical sense of vision must have observed the apparent

weakness there is in a spire that has perfectly straight sides, when

compared with one which has been entasised, and the same with all

columns. Here also the method to insure the correction can be easily

applied. The more important of these refinements are capable of being

made at the initial stage of design, without recourse to decimals

of two or three removes from the decimal point, or to mathematical

calculations.—_Abstract from the Building News_.

Testing Pile‐Protecting Compounds.

In 1882 several piles, coated with various patent anti‐teredo

coverings, were driven in the harbor of San Francisco for the purpose

of testing them. Recently Engineer Manson began pulling up the piles in

order to see the result of the experiments. A pile coated with Pearce’s

compound, composed of paraffine, limestone, kaolin, etc., was found

to be completely honeycombed by the teredos. The eucalyptus and cedar

piles were also nearly destroyed. In 1884 the two piles incased by A.

W. Von Schmidt in sewer pipe and cement, the twenty‐three coated by

Frank Shay with asphalt and wire cloth, the ten of McKeon & Co., coated

with warm cement containing a poisonous substance, and those of W. H.

Hayes, coated with Portland cement, etc., were examined by Colonel

Mendel and Mr. Manson. All showed signs of having proved failures. The

insect is ahead of the inventors up to date.

A Tower on the Mount of Olives.

The tower which is being erected by the Russians on the highest point

of the Mount of Olives is already several stories high, but one

more is to be added. The object is to make it so high that both the

Mediterranean and the Dead Sea may be seen from the top. A number of

bells will be placed in the tower. In digging the foundation, several

Christian graves were found, together with an inscription in Greek, in

which the word “Stephanus” could yet be deciphered.

TO OUR READERS AND PATRONS.

The present number closes our fourth volume and brings us to the end of

another year. Many subscriptions now terminate, and we ask our patrons

to be prompt in sending their renewals, thus avoiding the loss of any

numbers. The terms are only $2.50 a year.

Considering the wealth of illustration, the variety and value of

information presented, this work is by far the cheapest of anything in

the same line.

To builders, and those contemplating the erection of dwellings or other

structures, our paper has proved to be of great value.

With every number, during the past two years, we have given plates

in colors of many new buildings, with specifications, accompanied by

extra special sheets of details. In most cases these have been so

complete as to enable the builder and contractor to proceed at once

with the construction; and on the plans thus presented, thousands of

new buildings have been erected in all parts of the country. In almost

every town in the land attractive dwellings are now to be seen, which,

on inquiry, will be found to have been built from SCIENTIFIC

AMERICAN plans.

No architectural publication in the world presents to its patrons

so many practical specifications and drawings without cost, except

the merely nominal subscription rate of $2.50 a year. It is hardly

necessary to remind the builder that he would be obliged to pay several

hundred dollars if the same number of plans were to be specially

prepared for him.

In addition to the colored plates, details, and specifications, we have

furnished a large number of other new architectural illustrations and

many pages of valuable information. In all, the past year’s volumes

include about one thousand engravings.

We remind our readers of these items with the hope they will mention

them to their friends, and, if possible to secure a new subscription,

to send it in with the renewal of their own.

Our aim is to improve and enlarge the sphere of work, rendering it more

and more valuable. To this end we need the support and encouragement of

as many subscribers as possible. If each one of our friends will do a

little for us in this direction, all the parties concerned will derive

benefit.

If any of readers have inquiries to be answered, or suggestions to

make, relating to subjects or features they would like to see treated

in our paper, we shall, at all times, be pleased to hear from them.

Architects and builders who desire to see their plans reproduced in our

pages are also invited to communicate with the editor.

A CORRECTION.

In our November number an error was made in the estimate given for the

$2,500 house illustrated in our colored plate. The cost should have

been stated at $3,400. In some way the bill for mason work and painting

was omitted. These additions and other modifications bring the cost up

to the above sum.

A SUBURBAN RESIDENCE.

One of our colored plates this month represents a suburban dwelling

built of dark trap rock, trimmed with buff brick, and roofed with

ornamental stamped iron plates. It is now being constructed in New

Jersey, by days’ work, at a cost of about $9,250. The following is an

abstract from the

A LARGE CONTRACT FOR ROOFING PLATE.

The interesting picture of the Western Tennessee Hospital for the

Insane, at Bolivar, in that State, which will be found in our

advertising pages, will command the attention of humanitarians and

administrators everywhere. Such buildings, devoted to such purposes,

are not frequently to be met with. The announcement made in connection

therewith, that the Alderly brand of square Terne plate was selected by

the commissioners for the roof, gutters, and valleys of the structure,

requiring over 1,000 boxes of roofing plate, presents, in a forcible

way, the claims of that article. It is manufactured and sold by Messrs.

Gummey, Spering, Ingram & Co., of Philadelphia, Pa., and Liverpool,

England.

A DWELLING OF MODERATE COST.

This cottage is built in Plymouth Park, Buzzard’s Bay, near Wareham,

Mass., one of the most charming locations on the New England coast.

From the veranda a beautiful view is obtained of the bay and coast.

The cottage is erected on one of the knolls (which is one of the

features of the park), and has for a background a grove of pine and

oak trees. The shingles are treated with “Cabot’s creosote stains” of

the following colors: On roofs, a steel gray, and on sides, sienna.

The clapboards are painted a light olive green and trimmed with bronze

green and Indian red. The studs of hall, dining room, and parlor are

exposed, and together with underboarding and beams overhead are planed

and sand‐papered, and all woodwork is given two coats of shellac of

light finish. The second floor is plastered (sand finish). The contract

price for cottage was $2,800 complete. The architect is Chas. E.

Miller, 149 Broadway, N. Y.

It is said that the ova of tapeworms are frequently deposited in the

wrinkles of a lettuce leaf and near the mid rib of a cabbage leaf, and

so it behooves those wishing uncooked leaves of any kind to have them

carefully washed.

A FRENCH COTTAGE.

We publish herewith the plans for a house designed by M. A. Fatalot

and erected by M. Valette, architect. It is built on the side of the

terrace (Rue Babie), on the green hills which overlook the Seine.

[Illustration: A FRENCH COTTAGE—HOTEL DE PEINTRE, A MEUDON.]

The construction is very simple. The architect was, in fact, asked

to use the strictest economy. The first floor, built over a cellar,

consists simply of a vestibule, A, which opens into a dining room, C,

a bed room, D, a kitchen, B, the water closets, E, and the stairway.

The latter is constructed of wood and leads to the second story, which

serves as both studio and drawing room. This room is lighted by the

large window shown in our perspective view. The walls of the building

are of stone—stone from Meudon, nicely colored—and Bourgogne bricks

of different shades form the design of the frieze. The basement is of

dressed stone; the pediments of the gables and the cornice are covered

with a plaster of sand and mortar colored in imitation of stone. The

tops of the pediments are decorated with Parvillee faience. The perron

is of Bagneux stone and the mullions and supports of Euville stone.

The following is a detailed list of the expenses:

Masonry $1,480

Our Forestry Problem.

According to latest estimates, we consume yearly, with our present

population of sixty millions, not less than twenty billion cubic feet

of wood. The amount is made up, in round figures, in the following

manner:

2,500,000,000 feet for lumber market and wood manufactures;

360,000,000 feet for railroad construction;

250,000,000 feet for charcoal;

500,000,000 feet for fence material, etc.;

17,500,000,000 feet for fuel.

To this it will be safe to add, for wasteful practices and for the

destruction by yearly conflagrations, at the least, twenty‐five per

cent.

The average yearly growth of wood per acre in the well stocked and well

cared for forests of Germany has been computed at fifty cubic feet.

Applying this figure to our present requirements, we should have an

area of not less than five hundred million acres in well stocked forest

to give us a continual supply of all kinds for our present needs. Now,

a careful canvass made four years ago developed the result that the

existing forest area in the United States, excluding Alaska and Indian

Territory, comprised almost five hundred million acres (489,280,000);

but it is well known to everybody who is acquainted with our forests

that they cannot compare in yield with the average European Continental

forests under systematic management. Much of what is reported as forest

is useless brush land or open woods, and depreciated in its capacity

for wood production by annual fires, by which the physical structure of

the leaf mould is destroyed, and thus, too, its capacity for storing

the needful moisture, reducing wood production, and killing all young

growth.

Without care, without management, and left to the kind but uneconomical

work of nature, interfered with, in addition, by rude and ignorant

action of man, it is doubtful whether, on the existing area, one

half the amount of wood is produced yearly which we now require. We

have, therefore; beyond doubt, reached—if not passed—the time when

increased drain means squandering of capital, and when regard to

husbanding, to careful management, to recuperation of our forests,

and planting of new forests is required for the purpose of merely

furnishing raw material; and it should not be forgotten that to

reproduce the quick growing white pine of an acceptable quality and

sufficient size requires not less than eighty to one hundred years,

and for the long leaved pine two hundred years; that, altogether, wood

crops are slow crops; that nothing of size can be grown under a quarter

of a century at the best.

That this is a business requiring intelligent national consideration

is apparent. Not less so if we appreciate the magnitude of the values

resulting from it. The total value of forest products in the census

year was placed at $700,000,000, or ten times the value of the gold

and silver production, five times the value of all coal and mineral

production, and exceeding every one of the agricultural crops, corn and

wheat not excepted; and representing in value about thirty per cent. of

the total agricultural production.

Of injuries wrought locally by the reckless clearing of hill sides and

of deterioration of the soil due to inconsiderate action of man, I

could entertain you by the hour. The country is full of examples. Any

one who wishes to study the effect of such denuding of hill sides upon

the soil, the water flow, and agricultural conditions, need not go to

France, Spain, Italy, Greece, or Palestine. The Adirondack Mountains

are within easier reach, where the thin cover of earth exposed to

the washing rains is carried into the rivers, leaving behind a bare,

forbidding rock and desolation, while at Albany the Hudson River is

being made unnavigable by the _debris_ and soil carried down the river.

The government has spent more than ten million dollars, I believe, and

spends every year a goodly sum, to open out a passage over the sand bar

thus formed.

Go to the eastern Rocky Mountains, or to Southern California, and you

can gain an insight into the significance of regulated water supply for

the agriculture below, and also learn how imprudently we have acted

and are acting upon the knowledge of this significance by allowing the

destruction of mountain forests in the most reckless and unprofitable

manner. Along the shores of Lake Michigan, and along the sea coast, we

are creating shifting sands by the removal of the forest cover, to make

work for the ingenuity of our children in devising methods for fixing

these sands again. The vegetable mould with which the kind forest had

covered the alluvial sands of the southern coast plain we are taking

pains to burn off in order to replace it with expensive artificial

fertilizers.

That the great flood of the Ohio, which cost the country more than

twenty million dollars, was entirely due to deforestation, I will

not assert; but it must have been considerably aggravated by the

accumulation of minor local floods, due to the well known reckless

clearing of the hill sides, which sent their waters down into the river

in torrents. At the season when the winter snows are melting, watch the

newspapers, and you will find an almost daily mention of the disastrous

ravages of brooks and streams, many of which injuries could have been

prevented by avoiding the creation of their distant and indirect cause.

Thus we may multiply examples all over the country, showing harmful

local influences upon agricultural conditions due to forest devastation.

That the vast stretches of land in the Northwest, from which the white

pine has been cut and burned off, present the aspect of a desolation

which sickens the heart, you may hear from every one who has seen these

deserts unnecessarily wrought by man. Every traveler in this country,

be it to the White Mountains, to the Adirondacks, along the Alleghany

Mountains, be it through the Rockies or the redwoods of California,

cannot but be startled by the desolate, sad aspect of many of these

once beautifully clad mountain crests.

And we are a nation hardly a hundred years old, with over thirty acres

per capita to spread ourselves upon. What will become of us when we

must live upon five acres per head? We are far enough advanced in our

recklessness of disregarding the indirect significance of forest areas

to have learned a lesson at home, and to feel the necessity of being

more careful in the utilization of the forest, so as not to lose its

protection for our agricultural and general interests.

The means for its solution I may only briefly indicate. They are

education, example, encouragement, legislation. Some of these are

of slow effect. Others can be made to give results at once. Let the

United States government, which still holds some seventy million acres

of the people’s land in forests, mostly on the Western mountains,

where its preservation is most urgently needed—let the government

set aside these otherwise valueless lands, and manage them as a

national forest domain, and then the first effective step, a feasible

and not a forcible one, is made. Let the military reservations on

the Western treeless plains, which are still in the hands of the

general government, be planted to forests and managed as such. This

would be no doubtful experiment, would interfere with nobody, would

enhance the value of the surrounding country—and education, example,

and encouragement are provided, as far as it is in the legitimate

province of the general government. And such example, instead of

costing anything to the country, can be made self‐sustaining—nay,

productive—and would add appreciably to the people’s wealth.—_B. E.

Fernow_.

Mortar containing sugar has been employed in building the new Natural

History Museum in Berlin, and has proved far superior to common mortar.

It sets almost with the firmness of a good cement, while mortar made

with molasses became soft and brittle after a time. In Madras a mortar

is used with which either sugar, butter or buttermilk, shellac and eggs

are mixed. It holds well and takes a marble‐like polish.

Bamboo Tree.

Writing from China, a correspondent says that the Chinese have

developed the culture of the bamboo tree very wonderfully. They can

produce a perfectly black as well as a yellow bamboo. The Emperor of

China has one officer whose duty is to look after his bamboo gardens.

This valuable tree is found in all tropical and sub‐tropical regions,

both in the eastern and western hemispheres. An attempt has been made

in England, and with some success, to raise a dwarf species found at

an altitude of 12,000 feet in the Himalaya mountains. The new world

furnishes bamboo of the greatest diameter. The stems are usually very

slender, but in the northwestern part of South America is found one

species with a diameter of 16 inches. The Chinese put this plant to a

greater variety of uses than any other people. Some kinds of it when

it first shoots up from the ground are used as a vegetable as we use

asparagus, or it can be pickled in vinegar or made into delicious

sweetmeats. The plant has to be 30 years old to blossom, and then it

bears a great profusion of seeds and dyes. These seeds may be used like

rice, and a kind of beer may be made from them. In 1812 severe famine

in portions of China was prevented by the sudden blossoming of a great

number of bamboo trees. The stems of all the varieties are remarkably

silicious. One kind found in Java is so hard that it strikes fire

when the hatchet is applied to it. This has only a very slender stem,

which is polished and used as stems for tobacco pipes. This Protean

tree furnishes material for houses, boats, cordage, sails of boats,

telescopes, aqueduct pipes, water‐proof thatching, clothing, water

wheels, fences, chairs, tables, book cases, boxes, hats, umbrellas,

shields, spears, and paper. The pith is used for lamp wicks, so there

is no part of it that cannot be used for something. From some of it

exquisite carvings inlaid with gold and silver are cut, that exceed

in beauty the ivory carvings for which the Chinese are so famed.

Recently it has been put to another use. Mr. Edison has found that

the carbonized fibers of the bamboo furnish the best material for the

incandescent electric lamp, and has made use of it in his system of

lighting. In Burmah and Siam whole cities are built from bamboo. These

houses are made in pieces, lashed together, and raised on posts several

feet high.—_The Lumber World_.

FIREPROOF STRUCTURES.

An article recently published by us apropos of the Opera Comique

catastrophe has brought us several interesting communications, and,

among them, one from Mr. Hennebique, one of the designers of the 948

foot Belgian tower. Mr. Hennebique has established the fact that

structures in which iron is used in the flooring do not arrest the

ravages of fire, but fall even more quickly than those in which wood is

employed.

In fact, the beams that support the ceiling joists, flooring,

and laths, naturally combustible materials, are raised to a high

temperature, and, becoming red hot, bend under their own weight, and at

the same time shove the walls outwardly.

The flooring of Mr. Hennebique’s invention, which is composed of a

cement made of coal ashes, plaster rubbish, and hydraulic lime, is

refractory enough to resist the heat developed by combustion.

As may be seen from the figure, this flooring consists of tubular

girders resting upon very simple metallic anchorages. These girders

are of the composition above described, and thus constitute a sort

of monolith upon which any sort of a floor can be laid—terra cotta,

marble, wood, etc.

Aside from its being nearly completely incombustible, this sort of

flooring presents a great advantage, from an economical standpoint, in

consequence of the rational utilization of the materials employed. It

is unnecessary to say that the metal is perfectly protected against

oxidation.

Another advantage of this flooring is that it almost entirely prevents

the propagation of sound.

[Illustration: =HENNEBIQUE’S FIREPROOF FLOORING.=]

As may be readily seen, this mode of construction is applicable to

different uses and to every possible sort of decoration, such as

cornices, compartment ceilings, girders of various styles, as well as

pillars, pilasters, columns, and supports of every shape and every

resistance.—_Chronique Industrielle_.

Construction of Chimney Flues.

In a letter to the _Insurance World_ Mr. Thomas Boyd, architect, of

Pittsburg, Pa., gives the following practical information:

I have had considerable experience in examining buildings burned by

fire, having been associated with my father for eleven years, and

during that time have examined hundreds of buildings destroyed by fire.

I have traced more fires to the cause of defective flues than to any

other source, and I could refer you to buildings, not only in this

city but in others, where fires have occurred from this cause, and the

insurance men and the public in general stated that the fire occurred

from “unknown causes,” as it was first seen many feet away from the

flues.

In seventy‐five cases in one hundred where fires occur from “unknown

causes,” it can be traced to defective brickwork. Ordinarily, an

architect specifies that the brickwork shall be well slushed, and that

the flues shall be well pargeted or plastered on the inside. This is

a great error, as no flues should be plastered on the inside, and no

walls having flues in them should be slushed, as the term is generally

understood.

The flues should in all cases be built smooth on the inside, and all

the joints should be filled full of mortar, the vertical joints as

well as the bed joints. The lining of the flue or the four inches

surrounding the flue should always be kept in advance of the brickwork,

and the brick adjoining the lining and the second and third brick, and

so on, should be shoved in soft mortar up against each other. This will

fill all the vertical joints from bottom to top as laid. The slushing

that is ordinarily put in from the top only goes down into the joint

about ½ inch, thus leaving an opening the entire length of the wall,

and in some cases an opening which a mouse could crawl through. As it

is only a question of time when all the plastering that can be put on

the inside of a flue will fall off, it will leave these vertical joints

between the bricks open into the flue, and as the joists cross through

these joints in the brickwork, fire is liable to take place ten or

twenty feet away from the flue. I have taken down many old buildings in

which these joints were filled with carbon or soot.

If the flues are built as above described, any competent builder

or architect can find out whether the mechanics doing the work are

slighting it or not; but if the inside of the flue is plastered or

lined with terra cotta or any other material, you cannot tell whether

the wall is properly built or not until this plastering falls off,

which it will in the course of a few years. Thus all buildings erected

with plastered flues are liable to burn at any time.

I have made a practice for a number of years of building flues without

lining them, and then when the house is built, or as each story is

erected, I put a dense smoke in the flue and close the opening at the

top. If there is a hole the size of an ordinary pin head, the smoke

will find it and penetrate into the interior of the wall adjoining the

flue.

Roadside Plantations of Trees in Belgium.

The roadside planting of trees is carried out on a most extensive

scale in Belgium, forming a marked feature in the landscape of that

country. According to the report of M. J. Houba, State Head Bailiff

or Ranger of Woods and Rivers in Belgium, recently published in the

_Revue Horticole_, the total length of the highroads of Belgium in 1881

amounted to 4,227 miles, classified, as regards tree planting, in the

following manner:

=Miles.=

Roads already planted 2,417

„ still to be planted 264

„ which cannot be planted 1,546

—————

4,227

From this it will appear that, at the date mentioned, more than half

the entire length of the Belgian highroads had been planted, and that

the proportion would soon reach two‐thirds.

The number of trees used in forming these plantations amounted

to 871,685, representing in 1881 a money value of £415,986, the

average cost of each tree when planted having been about 2s. 6d. The

plantations had therefore at this date increased in value to nearly

four times the amount of the capital originally expended upon them.

The trees principally employed in these roadside plantations (already

made) are: Elms, 371,621; oaks, 130,828; poplars, 80,853; ash,

73,893; beech, 32,970; maples, 27,755; service trees, 24,630; Norway

spruce, 43,767; larch, 41,699. It will be seen from this list that

coniferous trees are largely used in Belgium for roadside planting. On

the other hand, the report only gives 897 plane trees, 976 acacias,

and 672 cherry trees, apple trees, and pear trees, showing that

while the Belgian authorities fully recognize the great utility of

these roadside plantations in other respects, they especially aim

at the production of timber of good quality in a commercial point of

view.—_The Garden_.

An Egyptian Temple.

An Egyptian temple appears to have been one of the most imposing

assemblages of buildings that can be well conceived. Avenues lined

with hundreds of sphinxes on each side led the worshiper to the

sacred precinct for the distance of thousands of feet, and thus the

mind, even when remote from the vicinity of the temple, received an

impression calculated to excite veneration. This avenue was terminated

by a stupendous mass of pyramidal form, above 200 feet wide and about

80 feet high, whose enormous proportion was naught diminished by the

vastness of the plain in which it stands, nor by contrast with the

mountains that overhung it. In the center of this propyleum is a door,

flanked in advance by an obelisk on each side, about 90 feet high,

and beside which are figures of colossal dimensions, 45 feet high,

sitting as guardians of the sacred portal. The effect of the whole

is gigantic, and calculated to impress the coming worshiper with the

fullest notions of his insignificance in the scale of material nature.

The triumphal gateway being passed, a magnificent court meets the eyes

of the beholder, having on each side a colonnade. And this court led

to a densely columned hall or vestibule, under the shades of which

the crowds of Egypt’s sons and daughters reposed to recover from the

exhaustion and fatigue caused by their journey under a burning sun to

the fane of their creature god. And here the mind also dwelt awhile on

the first impressions produced by the contemplation of the overpowering

majesty of the gorgeous mass. For the huge propylea, which inclosed

either end of the court, and the hall, with its forest of clustered

columns, which the eye could not number, and the playful variety

and copiousness of channeled hieroglyphics which left not a space

uncovered, and the brilliancy of the pigment which gave an endless

variety to the shafts and capitals of the columns, to the beams, the

walls and ceilings, bewildered the attention, and left not a moment of

repose to the wondering stranger. A lofty central avenue of columns,

above 60 feet high, forming, as it were, a triumphal way, leads under

a third portal, of dimensions by no means inferior to the others

just mentioned, and marked with what care and with what sanctity the

priests guarded every approach to the inner parts of the temple. But

this gateway passed, and a scene the most sublime burst upon the view.

An ample peristyle much larger than the one already passed, presented

itself to the eye, probably planted with trees, crowded with metaphoric

statues.

On either hand a double avenue of columns, less for convenience than

dignity of effect. In the center uprose the portico of the mass of

building, that formed the temple itself—the columns in dimension

more lofty, in decoration more rich, in proportion more graceful than

those of the courts. The dynasties that had ruled over the country

up to the period of the erection of this temple have their histories

graven on the walls and on the columns. The same pyramidal form gives

an appearance of endless durability to the mass, which is surmounted

by an immense hollowed cavetto having the center occupied by the

sculptured form of the agatho demon, or winged globe and serpents,

with outstretched wings extending over the center intercolumniation of

the facade, and seemingly a being of another world. Admitted beneath

this porch, the minds of the worshipers are prepared for the gloomy

inner penetralia, where every object was mysterious and emblematic.

Numerous doorways closed by curtains succeeded each other, and led from

vestibule to vestibule, which hindered the eye from penetrating with

sacrilegious gaze into the inmost sanctuary, all access to it being

forbidden to the multitude.

To these vestibules the light of day was denied, and the mind was

subdued by the gloom of the spot, for the attention was absorbed by

the contemplation of the sacred mysteries of the place and by the

effects produced on the attention by the huge incongruous figures of

granite—monstrous reflections of the gloomy minds of the religious

inhabitants of the sacred precinct, who sought to deify matter and the

animal instincts.—_T. L. Donaldson._

The White Ash.

“About twenty years ago, Prof. J. L. Budd, of Ames, Iowa, advised

keeping the seeds of the ash through the winter in kegs or boxes, mixed

with clean moist sand, taking care that they become neither too wet

nor too dry. Freezing will do no harm. The ground should be marked and

prepared as for corn, and planting at the intersections, placing four

to six seeds in the hill. They should be carefully cultivated, and the

next spring thinned to one plant in each hill, the vacancies being

supplied. By planting thus thickly, the young trees get a straight

growth. At the end of six years every alternate row north and south

should be thinned out, and at the end of ten years every alternate tree

in each row. When twelve years old, on good soil and proper culture

the first four years the grove would have 12,000 trees on ten acres,

averaging eight inches in diameter. By cutting the stumps close to the

ground, and covering with a light furrow on each side, a second growth

is obtained in eight or ten years, more valuable than the first.”

Prof. C. S. Sargent, in speaking of this timber, says: “To develop

its best qualities, the white ash should be planted in a cool, deep,

moist, but well drained soil, where it will make a rapid growth. That

the plantation may be profitable as early as possible, the young trees

should be inserted in rows three feet apart, the plants being two feet

apart in the rows. This would give 7,260 plants to the acre, which

should be gradually thinned until 108 trees are left standing, twenty

feet apart each way. The first thinning, which might be made at the end

of ten years, would give 4,000 hoop poles, which at present price would

be worth $400.

“The remaining thinnings, made at different periods up to 25 or 30

years, would produce some three thousand trees more, worth at least

three times as much as the first thinnings. Such cutting would pay all

the expenses of planting, the care of plantation, and the interest

on the capital invested, and would leave the land covered with trees

capable of being turned into money at a moment’s notice, or whose value

would increase for a hundred years, making no mean inheritance for the

descendants of a Massachusetts farmer. The planting of the white ash

as a shade and roadside tree is especially recommended, and for that

purpose it ranks, among our native trees, next to the sugar maple.”

Prof. B. G. Northrop says in reference to this tree: “One of the

most valuable of our native trees is the white ash, and, all things

considered, it is one of the most profitable for planting. Combining

lightness, strength, toughness, elasticity, and beauty of grain in

a rare degree, it is in great and growing demand for farming tools,

furniture, interior finishing of houses and railroad cars, the

construction of carriages, for oars and pulley blocks, and many other

purposes. The excellence of our ash is one secret of the preference

given abroad to American agricultural implements. It is hardy, will

bear the bleakest exposure, is a rapid grower and attains large size,

but will not thrive on poor lands. It is every way superior to the

European ash, much as that has been cultivated and lauded abroad. It

is now found widely in the nurseries and young plantations attached

to the forest schools of Europe. Director General Adolfo di Beranger,

president of the Royal Instituto Forestale, at Vallombrosa, pointed me

to his plantations of _Fraxinus Americana_ with a tone which implied

that is the tree of which Americans may well be proud.

“The ash is a fine ornamental tree for private grounds, public parks,

or for the wayside. When planted closely for timber they grow straight

and free from low laterals, and early reach a size that makes the

thinnings valuable for poles and fencing.

“The seeds of the white ash are abundant, ripening by the first of

October. They may be easily gathered after the first frost. If sown in

the fall, they should be covered with three inches of straw. If to be

sown in the spring, the seed may be mixed with damp sand.”

Sawdust.

Sawdust has been a source of worry and expense to mill men in various

ways, though it is to be admitted that in utilizing it to some extent

as fuel they have in part solved the problem of its economical

disposition. Lately, there has sprung up a certain demand for it, and

the problem of its cheap shipment is now one that presents itself.

A Yankee inventor has tried baling it, and appears to have devised

a scheme that accomplishes the purpose successfully. He makes the

sawdust into bales, and has progressed so far as to be able to

compress thirty‐two cubic feet, or a quarter of a cord, into a package

three feet long by two feet on each of its sides. As this occupies

only twelve cubic feet, the reduction is sixty‐two and one‐half per

cent. of its original bulk. The machine used is nothing more than an

ordinary hydraulic press, which is arranged in a manner similar to a

hay or cotton press. The sawdust is pressed into bales and at the same

time inclosed in a burlap covering, making a neat and easily handled

package for shipment. Small pieces of wood, shavings, etc., may be

baled with the sawdust or separately with equal facility. It appears

a simple method of putting this bulky stuff in convenient shape for

shipment, and it would seem might be employed to advantage wherever a

market can be found for this species of mill refuse.—_The Timberman._

DWELLINGS AT GLENRIDGE.

We illustrate a few of the tasteful residences which have been erected

at Glenridge, N. J., a charming suburb of New York City, situate on

the line of the Delaware and Lackawanna Railway. Glenridge is 14 miles

from New York, and the time required for the trip, including the ferry

across the Hudson River at New York, is about 40 minutes. The dwellings

we have chosen for illustration have been recently erected. They vary

in cost from $4,000 to $6,500 or more. We can supply on application

such further information as readers may desire.

Fire Bricks.

Mr. W. Y. Dent, in a Cantor lecture at the Society of Arts, London, on

building materials, gave an account of some of the chemical problems

involved in the constituency of fire clay and fire bricks.

The plastic clays consist of silica and alumina chemically combined

with water. They are hydrated silicates of alumina, the plasticity

depending upon the water that enters into their composition. The

water with which the clay is chemically combined can be expelled at

a temperature a little above that of boiling, without detriment to

its plasticity, but the whole of the water contained cannot be driven

off without raising the temperature to dull redness. Silica, alumina,

and lime are separately very infusible substances, and are capable of

resisting exposure to very high temperatures without softening. It is

on account of its extreme infusibility that lime is found to be the

most suitable material for the cylinders upon which the oxyhydrogen

flame is made to impinge to produce a brilliant light, the intensity

of the light being due to the extremely high temperature to which

the lime is raised. Lime, however, from its want of cohesion, could

never be brought into general use for such purposes as fire clay is

employed, and this is also the case as regards silica, which requires

the addition of some substance of a basic character, with which it

will unite, and so cause the particles to bind together. The nearest

approach to the use of silica alone as a fire brick is in the case of

the Welsh brick, made from the Dinas rock in the Vale of Neath.

This material, before being made into fire bricks, had long been used

for repairing the furnaces at the copper works of South Wales, for

which purpose its peculiar property of expanding when subjected to

the influence of a high temperature, instead of contracting, as in

the case of some other fire clays, renders it particularly suitable,

the cementation of the bricks being facilitated by the increase of

temperature. This Dinas rock occurs in various conditions, from that of

a firm rock to that of disintegrated sand, and a mixture of about 1 per

cent. of lime is, therefore, necessary in order to make it into bricks.

Dinas bricks will stand very high temperatures, but are more friable

than ordinary fire bricks, and will not resist to the same extent the

action of basic substances, such as furnace slags, containing much

oxide of iron. They are, besides, porous and readily absorb moisture,

rendering it necessary for furnaces built of them to be gradually

heated, as they are liable to crack if sufficient time is not allowed

for driving off the moisture. The composition of the clay used for

fire bricks is a question of great importance, inasmuch as its quality

depends greatly upon its chemical constituents, although its power of

resisting fusion, when exposed to intense heat, is effected by its

mechanical condition.

The same materials, when mixed together in the form of a coarse powder,

will require a higher temperature to fuse them than would be the

case if they were reduced to a fine state of division. The qualities

required in fire bricks are that they should bear exposure to intense

heat for a long time without fusion, that they should be capable of

being subjected to sudden changes of temperature without injury, and

that they should be able to resist the action of melted copper or iron

slag. The Dinas brick, which contains 98 per cent. of silica, will bear

exposure to a higher temperature than most others, but it will run down

sooner when in contact with melted iron slag. Ganister is the name

given to a fine grit which occurs under certain coal beds in Yorkshire,

Derby, and South Wales, and the black ganister from the neighborhood

of Sheffield is especially adapted for lining cupola furnaces, owing

to its capacity to stand high temperatures without shrinking, in

consequence of the large quantity of silica it contains.

Fire bricks made of silicious clays from granitic deposits in various

parts of Devonshire also contain a large proportion of silica, but

their powers of supporting exposure to high temperatures are materially

increased by the coarseness of the particles of disintegrated granite

of which they are composed. The material employed for the Dinas

bricks, as well as the others mentioned, differs considerably in its

character from what is ordinarily understood by the term fire clay,

as used in the manufacture of the celebrated fire bricks of Blaydon

Burn, Stourbridge, or Glenboig; the quality of which, as regards their

chemical composition, depends upon the relative portions of silica and

alumina, and their freedom from iron oxide and alkaline salts, the

presence of which tends to render the clay more fusible.

Improvements in Making Portland Cement.

Clay is taken as dug from the pit, without being dried, and mixed with

the usual proportion of lime, a portion of which is used as limestone,

the remainder as freshly burnt lime. The burnt lime is first added in

such proportion that the water in the clay exactly suffices to slake

it, and the heat given out effects the necessary drying. The limestone

is then added and the mixture ground in a mill to the usual degree of

fineness, made into bricks, calcined, and the “clinker” reduced to a

fine state of division as usual.

Typhoid Fever Carried by Well Water.

The following account of the transmittal of cases of typhoid fever by

well water is sent us by Dr. Henry B. Baker, secretary of the Michigan

State Board of Health. It is made to him by Dr. H. McColl, of Lapeer,

Mich.

Dr. McColl reports: About September 1, 1887, Myron Gardner, railroad

employe, came from the South sick with fever to his father’s house. He

was supposed to be malarial. No care was exercised with stools in the

way of disinfection, but they were thrown into privy vault in rear of

house, and in close proximity to well. Wash water was thrown on the

surface of the ground, which was very dry at the time. About September

7 or 8, a copious rain fell and soaked the sandy soil; and on September

14, Wm. Gardner and wife, father and mother of Myron, and E. D. Gardner,

a brother (who was a student in my office), and who boarded at home,

were attacked with fever. On this day I got home from Washington, and

found four of them down with a severe type of typhoid fever; and in two

weeks Myron’s wife and child were attacked; also a child across the

street at Terry’s, who had used water from the Gardner well; about the

same time three cases in the Clifford house, south of Gardner’s, who

also used water from the Gardner well. None of the people from either

of these houses were in the Gardner house. In the Walker house, still

further south, one case has occurred, and I was at a loss to account

for this case till a few days ago, when the young man said that at the

mill where he was working they had used the Gardner water for a few

days, owing to the disarrangement of the pump at the mill. Two others

of the mill hands—Anderson and Lester—who used the same water were

attacked about the same time. Lester is now convalescent. Anderson is

dead, as also the child at Terry’s. When I took charge of the cases,

I ordered the discontinuance of water from the Gardner well and the

disinfection of the stools, and no new cases are now reported. People

who assisted to take care of the Gardner and other families, and who

use water from other sources, have not been attacked. Clearly, Myron

Gardner brought the fever home, the well became infected after the

first rain from slops and privy, and the other cases got their seed

from the water.

Dr. Baker adds: The foregoing instructive account of the way typhoid

fever was spread, in one instance, is produced in the hope that

it may lead others to trace the spread of this important disease,

and, what is of greater importance, act intelligently for the

prevention and restriction of the disease, as Dr. McColl did in this

instance.—_Sanitary News._

An Unsafe Church.

About a month ago, Inspector of Buildings Griffin discovered that the

wall on the southern side of the Warren Avenue Baptist Church, Boston,

Mass., was bulging. He climbed to the roof, and was astonished to find

that the scissors truss that supported the pitch of the roof was not

bolted together, but was fastened only with railroad spikes.

The wall was out of plumb fully nine inches. A peremptory order was

issued to vacate the church. Then a more careful examination was made,

with startling results.

The truss was laid bare, and then it was discovered that the sole

support for the roof of the great building consisted of three iron rods

one and one half inches in diameter.

The cross rods were of no use, because the wood had shrunk away and

the bolts could be rattled. The upper and lower chords of the truss

were made of eight two‐inch planks, and where the cross rods had been

put through and clinched the auger had cut off one plank and part of

another, weakening the truss by one‐eighth.

The lower chord of the truss was cut completely through in two places.

It is said that it will cost nearly $200,000 to repair the church,

which is one of the largest in the city.

It would not be a bad idea for the trustees of other churches to have

the trusses carefully examined.

Cedar Pavements.

To pave a city with cedar would seem to be a luxury, but it appears

that in the city of Chicago, out of 277.71 miles of paved streets,

there are 213.35 miles of cedar blocks, of which nearly forty miles

was laid last year, and the Chicago _Tribune_ says it is the cheapest

pavement laid in the city. Dead cedar brought from the vicinity of

Green Bay, Wis., was first used, but it was found that it did not wear

well, and live timber is now required. The cedar is a tree which does

not taper rapidly, and one of good size should furnish a stick 30 ft.

long. The logs are brought here by boats in lengths of about 6 ft.,

with the bark still on, peeled, and cut into blocks 5 in. long. The

blocks range in diameter from 3 in. to 9 in., and cost 50 to 60 cents

a yard, measurement being made after they are laid. The process of

paving a street with cedar blocks is much the same as was used with the

Nicholson pavement. A sand foundation is first provided, and on this

are laid boards which serve as stringers. On the stringers planks are

placed parallel with the curb, and the cedar blocks are stood on end on

the planks. The interstices between the blocks are filled with gravel

and coal tar.

For the last three years block pavement has cost in Chicago from $1.00

to $1.30 a yard. The life of cedar block pavement is three to seven

years, and it is an excellent pavement when first laid. It is believed

by many to be detrimental to health from the fact that it absorbs all

liquids falling upon it, gives them back in the shape of vapor under

the influence of the sun, and is itself constantly decaying. It is

stated as a curious fact that this pavement wears out faster on streets

where traffic is light than where it is heavy. Cedar blocks are used

for paving all through the West, but more freely probably in Chicago

than in any other city in the world. They are cheap, and that is a

great point in their favor.

Hemlock.

Respecting the merits of hemlock, the _Minneapolis Lumberman_ has

a good word in its last issue. It quotes from a correspondent at

Williamsport, Pa., regarding the experience with the wood there as a

foundation for paving blocks; and in regard to a stretch of Nicholson

pavement there which had been down sixteen years, goes on to say:

“The blocks had been placed on two thicknesses of one inch hemlock, the

boards coated both sides with coal tar. When the pavement was taken

up, the boards were found to be in good condition—so perfectly sound

that they were put back again for possibly another sixteen years. The

correspondent says that out of a mile of sixty foot street, less than

10,000 feet of the old planking was condemned. There seems to be no

question as to the superlative merit of hemlock for paving purposes.”

This is valuable testimony, and better evidence of the lasting

qualities of hemlock under paving blocks than any Western experience

has produced, for the reason that it has nowhere in the West been

so long as that in use. It has been recognized, however, as a wood

excellently suited to this purpose, and is employed almost exclusively

wherever the cedar block pavement is freely used, which includes a

good many of the large cities in the United States, and practically

all Western towns in which any paving is done. It is apparent that

lumbermen are beginning to take a strong interest in hemlock, and

evidences of its growth in favor are becoming rather plentiful. It

occasionally gets a setback from some local dealer, who has come off

second best in an encounter with its slivers, but it is bound to come

more and more in use in spite of the strong objection that is made to

it by some users. Its light weight and great strength for many building

purposes are factors that tell.—_Timberman._

Collapse of Walls of Burning Buildings.

Mr. Alex. Black, writing to the _Building News_, says: The expansion

of brick by fire heat may be estimated at rather above half that of

wrought iron; and of mortar at about one‐fourth more than that of

wrought iron. The mortar joints in the wall may occupy, say, one‐fifth

to one‐sixth of the height of the wall. There is no accurate data as

to the maximum heat developed at Whiteley’s fire. It, however, depends

on the nature of the contents, etc., consumed and the accumulation of

draught currents. If there is free lime, etc., in brick or mortar,

there is added to the expansion more or less disintegration, which

would become not the least potent cause of collapse.

We may assume that the interior surface of the brickwork exposed to

the fire expanded, say, 1 in. in 8 ft. or 10 ft., vertically and

horizontally, which would produce a distortion by buckling, or curving

inward, dish‐like, of the inside half thickness of the wall, both

vertically and horizontally, leaving for a time the outside half

thickness (say, for convenience of description) not much disturbed;

in the meanwhile, air gets in between these inside and outside half

thicknesses, or slices, and it may become gradually expanded by heat

and help to force them further apart until the whole wall collapses.

In setting iron girders, the usual practice appears to be to build the

ends solidly in the wall to act as a tie; but by having cross flanges

at ends the wall may be built close to these on inside toward interior

of building, and space left for expansion on their outside; but this

space is of no use without the ends of the girders are set upon rollers

or rockers, as is done for bridge girders, because the rigidity of wall

would not be sufficient to withstand undisturbed the expansive pushing

out, or horizontal thrust, of loaded girder end if resting upon a rough

bearing plate or block.

If building timber joists into walls, it is a safe method to bevel off

the upper corner equal to the bearing of the end in the wall, which

allows the projecting portion of joist, if broken accidentally, to drop

down without disturbing the wall, by the leverage which it would exert

if built in the wall in the usual way.

A $2,500 CALIFORNIA HOUSE.

California can justly boast of a larger number of pretty places and

picturesque localities in which to erect residences of moderate cost

than can be found in any other State in the Union. The beautiful town

of Alameda, covering, as it does, a large extent of ground, embracing

several square miles, may be regarded as a paradise for those who wish

a quiet retreat, away from the din and confusion of the city, and yet

be in close connection with the great mart. Nearly every portion of

the town is covered with a natural growth of oak trees. Nor does this

growth stop at this point. For a long distance to the north the ground

is covered by the beautiful trees from which the neighboring city of

Oakland derives its name.

Extremes meet in architecture as well as other matters. Some æsthetic

persons have sought to copy the humble abode of the laborer in the

external view of a dwelling, while the internal arrangements and

fittings rival those of Aladdin’s palace. Others seek to have the

outside present to the eye a conglomeration of whimsical ideas, while

they have not deigned to cover the floors with a carpet, nor have a

door between any of the rooms or halls, excepting those connecting with

the outer world.

Much benefit has been derived from these whimsical erections, and it

is only by much study and close application to the fancies of their

clients that architects have been enabled to prepare the beautiful

bijou plans, a good representation of which is given in this issue. In

justice to the architectural profession, we must say that no portion

of their practice has been so usefully bestowed as that which has been

bestowed upon the production of plans for such homes, a full plan of

which accompanies this article.

[Illustration: A CALIFORNIA HOUSE FOR $2,500.]

The elevation, as shown, is a model of neatness and economy. At once

attractive in appearance and substantial in all its surroundings, it

does away with all those horrible idiosyncrasies and bugbears of the

Elizabethan and Queen Anne styles. There are no small windows to cause

the one who cleans them to utter a whole vocabulary of cuss words at

the architect who made so many corners to dig out. There is no part of

California but what needs all the sunshine that was intended to enter a

room, and the large windows shown allow the heat and light to make glad

the hearts of the dwellers therein. Even with the thermometer at 100

degrees and over in the shade at noontime, still, when evening comes,

the cool winds that invariably bless the sleep of those who are tired

from their daily toil has easy ingress from these same large windows.

And in winter, from the absence of snow in all of our beautiful

valleys, the same windows are a source of joy and comfort for the

occupants to observe the driving rains, or admit the blessed sunshine

as it pierces through the wintry clouds.

Great care should be exercised in painting the exterior. The colors

selected should be a happy blending of light and dark shades. They

should be graded from rich, heavy grades at the bottom to the lighter

tones at the gable peaks, preserving, through the intermediate section,

a consistent harmony. The roof may be of dark slate color. The

trimmings may be colored with a combination of blue, black, and Indian

red. The body of the house may be varied to suit the above. It must be

distinctly borne in mind that all buildings of the same class cannot be

treated alike. Trees have a wonderful effect on colors used, and the

main study of the painter and owner should be that the salient points

of form and detail be enhanced by the proper selection of the various

colors. By all means, if you are building a home for yourself, take the

good wife into your confidence, and let her judgment be given on the

various colors to be used.

The arrangement of the rooms, as shown by the plan, is very desirable

for any one with a small family. A feature is made of the entrance

way. From the hall, one can pass either to the parlor or dining room,

the latter being the general sitting room. The parlor is large—13

× 17 feet in size. It has a fireplace, as shown. A cornice is also

designated. Sliding doors connect this room with the dining room, the

size of the latter being 12 × 17¾ feet. A cornice and fireplace are

also shown. In case of company or family gathering, the two rooms will

be practically one. The porch shown in front will be very handy for the

gentlemen who smoke, or, on warm days the ladies can use the same for

sewing purposes, sheltered, as the plans show, by the roof overhead.

You pass from this room into a hall, from which you can enter all the

rest of the rooms. The main chamber is 12 feet 6 inches by 16 feet 6

inches, besides a large bay window, having four windows for light and

air. There is also a cornice in this room, and a place for a stove to

connect with parlor chimney. There is a very large closet, and also

wash room, which is well lighted and ventilated. Passing along the

hall, we next come to a large linen closet. This will be found very

serviceable for the storage of the linen in daily use. Then comes a

large chamber, 11 feet 6 inches by 12 feet. No cornice is shown. Should

a fire be needed in this room, a patent flue could be placed therein,

starting from near the ceiling. A large closet is also connected with

this room. At the end of the hall is the bath room, 6 feet 3 inches by

9 feet 6 inches. A wash bowl and water closet are shown. The window,

being directly over the tub, assures perfect ventilation.

On opposite side of hall from bath room is a room designated as

breakfast room, in size 10 × 11 feet, with two windows. This can be

used as a bed room, should the dining room suffice for the needs of

the occupants of the house. This room is very convenient, as it can be

reached by three different ways. The next room is the kitchen, in size

10 × 13 feet, with plenty of light and ample means of ventilation. The

place for the stove pipe is indicated by the dotted lines leading to

the dining room chimney. Should it be found more desirable to have the

stove in a different position from that indicated, a patent flue can be

put in, starting near the ceiling. A large pass closet, amply fitted

with drawers and shelves, connects with the dining room. There is also

a large pantry fitted up with bins, etc.

A stairway is shown, near breakfast room, leading to the attic. No plan

is given of the latter, as the space can be divided according to the

individual tastes of the parties building. The rear hall is 3 feet 6

inches wide.

The whole plan is very compact, and will bear careful study. The detail

drawings, as shown, will give an adequate idea of the various finishes.

Each one is distinctly marked.

We append a general set of specifications to aid those who may see fit

to adopt the design. Should any one want a complete set, we can forward

them a printed copy.

COST.

The above specifications are given as a general index of the work. No

accurate estimate can be given from them of the cost of the house.

Quality and price of hardware, etc., have been omitted, leaving same

to the pocket books of intending builders. As shown, with finishes

indicated by the details given, the house can be erected at a cost of

about $2,500. Of course this figure can be changed considerably. Using

the best of materials, etc., the price should be given at $3,000,

at which sum a truly cozy home can be obtained by those seeking a

permanent dwelling place.—_California Architect_.

The Architectural Era.

This is the title of a new monthly published at Syracuse, N. Y. It is

finely printed, handsomely illustrated, and full of interesting reading

matter. It forms a valuable addition to the architectural literature of

the day. The elegant style in which it is produced does honor to its

Blue Marking Ink for Boxes, Bales, etc.

Mix a sufficient quantity of ultramarine with barytes (sulphate of

barium, blanc fix) and water to produce the desired tint. It may be

rendered more permanent by adding some liquid glue (solution of glue

in acetic acid) or some starch paste, prepared with the addition of a

little wax.—_Chem. and Drug._

CHATEAU AT CASTELNAUDARY.

The internal decoration of the structure represented in the

accompanying engravings is due to Mr. Arnaud, an architect at

Carcassonne. The front already existed in part, and merely the

finishing of it is due to him. As for the parlor and dining room, of

which we give an illustration, these two rooms, like the rest, were

studied with very artistic care by Mr. Arnaud, and the execution of the

work was closely watched.

[Illustration: CHATEAU OF CASTELNAUDARY—FRONT VIEW—M. AUBRY, ARCHITECT.]

The chimney that decorates the dining room is of Echaillon stone, and

was made at the works of Mr. G. Biron. It is 14 feet in height, and

cost, all carved, $1,400. The flooring of the rooms is of oak, of two

colors, and was put down by the house of Idrac, of Toulouse, which

makes a specialty of old oak inlaid floors. The color of the old oak,

introduced into the very substance of the wood, lasts an indefinite

length of time. The wainscoting of the dining room and that of the

parlor is of walnut, and forms a frame, in the case of the dining

room, for old tapestry. In the parlor the panels are covered with

large‐figured cretonne.

[Illustration: INTERIOR OF CASTELNAUDARY CHATEAU.]

The ceilings are of plaster, with mouldings. To that of the dining

room are affixed, by invisible hooks, some old Japanese plates. These

produce a very happy effect in the ceiling as a whole, and in nowise

injure it. The ceilings are painted in softening tints, the principal

of which are red, blue and maroon. The dining room cost, as a whole,

$3,600, the old tapestry included. It is 24 × 30 feet, and the parlor

is 28 × 37 feet.—_La Construction Moderne_.

Nails.

A test has recently been made of the relative value of wire and cut

nails, with results quite at variance with generally received opinions.

This test, given below, is published in a circular issued to the nail

trade by the Wheeling nail manufacturers, and was made by a committee

appointed by the Wheeling manufacturers, who give the following result:

Number of nails in Pounds required to pull

pound. nails out.

Cut. Wire. Cut. Wire.

20d 23 35 1,593 703

10d 60 86 908 315

8d 90 126 597 227

6d 160 206 383 200

4d 280 316 286 123

This test showed the relative value of a pound of each kind to be as

follows:

1 lb. of 20d. cut nails equals 1·40 lb. of wire nails.

1 lb. of 10d. cut nails equals 2·01 lb. of wire nails.

1 lb. of 8d. cut nails equals 1·87 lb. of wire nails.

1 lb. of 6d. cut nails equals 1·49 lb. of wire nails.

1 lb. of 4d. cut nails equals 2·06 lb. of wire nails.

In obtaining the above results, two tests were made of the 8d. cut nail

and four of the 8d. wire nail; three tests each were made of the 6d.

and 4d. cut nails and 6d. and 4d. wire nails, and the average is shown.

The committee report as a result of their experiments that $1 worth of

cut nails will give the same service as $1.78 in wire nails, if at the

same price per pound.—_Building._

=Rabbit Remedy.=

A correspondent of the _Revue Horticole_ states that he has been

completely successful in saving both his vines and haricot beans from

being totally destroyed by the rabbits which swarm in this district by

using a remedy which he terms the “Bouillie bordelaise.” This consists

of a mixture of sulphate of copper (bluestone or blue vitriol) and

fresh slaked lime, in the proportion of 3¼ lb. of the former to

4½ lb. of quicklime in twenty‐one gallons of water. The bluestone

is first dissolved in a bucket of water, the quicklime is then slaked,

and when cool it is thrown along with the dissolved bluestone into a

barrel or other vessel of sufficient size; water is then added to make

up twenty‐one gallons, and the whole is well stirred up. The mixture is

conveniently applied with a whitewash brush, and in fine, dry weather

only should it be used. The object of the lime in the mixture is to

counteract any ill effects that the sulphate of copper or bluestone

might have on the vegetable tissues, and also to indicate that no part

of the stem or plant which it is intended to protect has been passed

over without receiving its proper share of the application.

How to Build an Ice House.

Under this head the _American Architect_ advises a correspondent as

follows:

1. The ice house floor should be above the level of the ground, or, at

least, should be sufficiently above some neighboring area to give an

outfall for a drain, put in in such a way as to keep the floor clear of

standing water.

2. The walls should be hollow. A four inch lining wall, tied to the

outer wall with hoop iron, and with a three inch air space, would

answer, but it would be better, if the air space is thoroughly drained,

to fill it with mineral wool, or some similar substance, to prevent

the movement of the air entangled in the fibers, and thus check the

transference by convection of heat from the outside to the lining wall.

3. A roof of thick plank will keep out heat far better than one of thin

boards with an air space under it.

4. Shingles will be much better for roofing than slate.

5. It is best to ventilate the upper portion of the building. If no

ventilation is provided, the confined air under the roof becomes

intensely heated in summer, and outlets should be provided at the

highest part, with inlets at convenient points, to keep the temperature

of the air over the ice at least down to that of the exterior

atmosphere.

In reply to inquiries from various correspondents we would say that

Messrs. Munn & Co., 361 Broadway, proprietors of this periodical, have

an extensive architectural bureau connected with their establishments,

and here, with the assistance of an able corps of architects,

they prepare, in the best and most prompt manner, designs, plans,

specifications, and details for all kinds of buildings, churches,

schools, stores, dwellings, etc. Hundreds of buildings in all parts of

the country have been erected from their plans. Messrs. Munn & Co. will

be pleased to furnish any information desired by readers relative to

any buildings illustrated in these pages.

Look to Your Drain Pipes and Wells.

The Rhode Island State board of health has completed its investigation

of the epidemic of typhoid fever at Conanicut park hotel, made last

summer.

At the opening of the season of 1887 trouble was experienced, but no

action was taken. Soon the people in the house began to be ill, and at

a time when all the rooms were taken and many more guests were to come

and occupy the cottage apartments. From the first symptoms, which were

not considered serious, the disease, which proved to be typhoid fever,

assumed a violent form, and Dr. Jernigan, on whose advice several

patients had come to the island, directed a practical plumber to make a

thorough examination of the premises.

The plumber discovered that the pipes leading from the water closets

had leaked into the cellar, and that from all appearances the leak

had existed from the first of the season. The sewage had run into the

well from which the water was drawn for general uses about the hotel.

Prior to the discovery of the contamination of the water, its sparkling

qualities had been praised by all the guests. The plumber also reported

that the ground near the well was saturated with the sewage, and that

when disturbed the earth emitted an overpowering and sickening stench.

From the cellar the investigation was continued to the well at the

north end of the house. It was dug quite recently, and the shaft had

been sunk through an old drain leading to a cesspool, and a portion of

the drain constituted a section of the well shaft.

The State board of health proposes to ask for an appropriation this

winter sufficient to pay for a careful examination of all the hotels

in the State, and the inspection and analysis of all waters used for

drinking purposes where there is liability of contamination.—_Sanitary

=Arch Construction.=

Iron construction has so completely superseded masonry for bridge

building that it would appear almost unnecessary to discuss the

question of the equilibrated arch for any large span. But the

mathematical principles of the arch have always been an interesting

subject with geometricians and theorists, and the theory, at any rate,

ought to form one of the subjects of the architect’s and engineer’s

education. As a problem of the equilibrium of forces, the theory of

arch construction is instructive, inasmuch as it presents us with

a concrete example of three forces balanced in a structure. The

other day, at the opening of the engineering section of the Bristol

Naturalists’ Society, at University College, Bristol, the president,

Mr. Charles Richardson, C.E., read a paper on arch building, in which

he advocated the employment of arches of equilibrium for bridges. The

author referred to the well known and elegant property of the balanced

arch, which is derived from the principle of the catenary or suspended

chain or inverted polygon of bars, each bar or link assuming the

position (inverted) that the arch stones of an equilibrated arch would

have. In Dr. Hutton’s valuable “Tracts on Bridges,” this principle is

followed in his elucidation of the arch, and readers of that work will

remember the diagrams given of various kinds of balanced arches, and

the curves of extrados necessary to insure equilibrium. The theory,

indeed, is older than Hutton. Belidor and Dr. Hooke both investigated

the form of the extrados from the nature of the curve, and this theory

has been made the foundation of a very interesting system of designing

arches. According to this theory of the question, the stones are

considered free from all friction—a condition which does not hold in

practice. Mr. Richardson follows, as far as we can see, this theory.

He enunciated the theorem that the weight on any point of the arch is

proportional to the vertical line from the road line to the intrados at

that point; that the horizontal thrust is the same throughout the arch,

and is equal to the weight on the crown per unit of area multiplied by

the radius of curvature there; and also that the bed pressure at any

point is equal to the horizontal thrust multiplied by the secant of

the angle the curve makes with the horizon at that point. This rule

is thoroughly mathematical and true for arches of equilibrium; and

the author exhibited an instructive model of an arch equilibrated,

and showed by inverting it, and suspending a chain weighted by steel

rods representing the loads at each point, that the latter coincided

with the road line. But the engineer‐architect has to do with arches

in which the element of friction enters; the stones are cemented, and

therefore the theory, however beautiful, does not hold good in every

case. Instead of the separate arch stones or voussoirs, he has to

deal with segments of the arch which turn upon certain edges. Thus

an arch which fails breaks into four parts, the crown sinks, and the

haunches rise, the joints at those points opening. One of the questions

to decide is the points at which rupture occurs, that being found to

find out what horizontal pressure each of those lower segments have

to sustain. From knowing the thrust and its point of action, the

stability of the arch will depend on the mass and weight of the pier.

The experiments of Rondelet and others have proved that the voussoirs

unite into segments of the arch, and tend to overturn the abutment,

acting rather as levers than wedges. He found, also, that the greatest

thrust was in arches with an even number of voussoirs or a point at the

vertex; that a keystone lessened the thrust. Nevertheless, the theory

of equilibration should be known by all architects and bridge builders.

In alluding to the materials, the author showed the impossibility of

dressing and bedding stones accurately. Practically, the stone built

arch is difficult to execute with precision. The facing stones only

are cut to the true curve, the backing being filled in with rubble

and roughly executed. With brickwork the bricks can be all bedded in

cement, being more convenient for handling, and a vitrified brick is

equal at least to the best stone in resistance. The brick arch should

be built in vertical bond, not in rings. Mr. Richardson finds that,

taking the safe load in cement at 5 cwt. upon the square inch, an arch

15 in. thick at the springing and 12⅚ at the crown is sufficient

for a span of 85 feet with a rise of ⅛ of the span. He says: “As

all loads and thrusts on such an arch are in direct proportion, if

each dimension were multiplied by four, we should have a span of 340

feet with a rise of 42 feet and an arch thickness of 5 feet. This 5

feet thickness would give a sufficient margin of safety for the moving

load, because 5 feet is only the necessary thickness at the springing,

while that at the crown would be 9 in. less. The total weight of this

bridge would be 100,000 tons.” Ring‐built arches are advisedly objected

to, as the rings tend to separate when any settlement takes place.

Mr. Richardson does not rely too much on friction, and he is right.

There can be no scientific arch construction that is not based on the

principle of equilibrium, the line of thrust being kept within the

middle third of the arch thickness; and in designing arches of brick

or stone the engineer should always be able by diagram to satisfy

himself of this condition. Whenever the line of thrust passes close to

the lower edge of the arch ring at the haunches, there must be undue

pressure and a tendency to open at the other edge. In other words, the

arch is inclined to drop at the crown. When it passes out of the arch,

failure must take place sooner or later. Instead of first deciding upon

the curve and road line, as is frequently done, the right course is to

find the line of thrust for the given span and loading, and then make

the arch conform as nearly as possible to this line. We agree with the

opinion that brickwork, if correctly applied, would be found to excel

iron construction in strength, durability, and economy—certainly in

appearance. In the construction of masonry arches, sufficient care

is not always bestowed upon the drainage of the arches—a cause, we

imagine, of many failures.—_Building News._

GILBERT SHEFFIELD, a Warren County, N. Y., lumberman, is one

of the men who believes in using his men well, and in doing something

to relieve the tedium of life in the woods. He has 35 men employed

at Tahawus, in Essex County, and says that for the past two years it

has been his practice to furnish them with copies of the prominent

newspapers, so that when they left camp they were as well informed

regarding current events as when they went in.

=NEW FORM OF CHIMES FOR CHURCHES.=

A new form of chimes for churches is being introduced in England,

which are said to give much satisfaction. They consist of a series

of metallic tubes suspended from a beam, as shown in our engraving.

They are struck by hammers, are very resonant, loud, and pleasing. A

correspondent of the _Pall Mall Gazette_, speaking of their effect,

says: “The music of many tuneful bells, harmonious, ever changing,

lending themselves to any simple air, easy of management, and mellowed

as the sound of cathedral bells.... Such music I have heard at

Coventry.”

=Tube Chimes.=

The new invention which goes under the name of tube chimes is a musical

chime in which metal tubes instead of bells are employed. The tube

chimes can be used for any purpose that bells are used for, and besides

are an economical substitute for bells. They are remarkable also for

a depth and richness of tone which one does not expect to find except

in high class cathedral bells. A tube chime for a church belfry is

especially suitable. The carrying power is not quite equal to that of

bells. A chime was lately set up in the tower of one of the Dorsetshire

churches which has pleased all concerned. Rung for the first time on

occasion of the harvest festival, it caused both delight and surprise

by the sweet and melodious tones it gave out. The invention has not

long been brought under public notice, but the demand for household

octaves in place of the inharmonious gong is already very large. Mr.

Harrington has a taste for music, and the idea of adapting tubes of

metal for the musical purposes of bells is no new one. It has taken,

though, many years of experiment and study to perfect the principle.

One difficulty, which was a great obstacle in the way, may be alluded

to. The large chimes are rung by bell ropes, but, contrary to the

plan of bells, there is an external hammer instead of the internal

clapper. If the hammers were made of sufficient hardness to prevent

wear and tear, the chime lost its sweet tones and became harsh. If the

hammers were less hard, they would constantly require to be replaced.

Fortunately, that difficulty, like many others, has been satisfactorily

got over. The chimes can be, it should be noted, tuned to any desired

pitch, and Messrs. Harrington & Co. are probably warranted when they

say: “The introduction of this invention will, we are assured, mark

the commencement of a new era in connection with church bells and

carillons, chimes for clocks of all sizes, dinner calls and gongs, and

all mechanisms in which musical bells are used or required, and in some

of these departments bids fair to work a complete revolution.”—_The

Architect._

MISS FLORENCE NIGHTINGALE’S HOME.

At the residence of Sir Harry Verney, Claydon House, Buckinghamshire,

a deputation from the Working Men’s Club of Whatstandwell, Derbyshire,

recently waited on Miss Florence Nightingale, for the purpose of

presenting to her an oil painting, by Mr. E. Crosland, of her late

home, Lea Hurst, as a token of their esteem, and in recognition of

the great interest taken by her in that institution. The deputation,

consisting of Mr. F. C. Iveson, Mr. Crosland, the artist, and Mr.

W. Peacock, assured Miss Nightingale of the love felt for her by

all classes of people at Whatstandwell and in that district, and of

their gratitude for her kindness and help in every good work. Miss

Nightingale, in thanking them for the present, which she admired very

much, expressed her continued great interest in the institution and its

members, and assured them of her hopes for its welfare. The deputation

were entertained at Claydon House by Sir Harry and Lady Verney. We are

permitted to copy the picture of Lea Hurst in our engraving, using a

photograph taken by Mr. J. Schmidt, of Belper.

[Illustration: LEA HURST, DERBYSHIRE, THE HOME OF MISS FLORENCE

NIGHTINGALE.]

Miss Florence Nightingale is a lady whose name has been deservedly

honored in England since the Crimean war and has become the symbol

of a particular type of personal efforts in the service of afflicted

humanity. She was born at Florence, in May, 1820, youngest daughter

and coheiress of W. E. Nightingale, Esq., of Lea Hurst, Derbyshire, and

Embley Park, Hampshire. She devoted her attention to the working of

schools for the poor, juvenile reformatories, and hospitals, inspecting

many such institutions on the Continent, and residing, in 1851, with

the Protestant Sisters of Mercy at Kaiserswerth, on the Rhine. She next

bestowed her care and gifts of her money on the London Governesses’

Sanatorium in Harley street. During the Crimean war, in 1854, when

the inefficient state of our military hospitals in the East demanded

instant reform, the hospital at Scutari, opposite Constantinople, was

established for the relief of sick and wounded British soldiers and

prisoners. It was resolved to form a select band of volunteer lady

superintendents and female nurses for this and other army hospitals.

At the request of the Secretary of State for the War Department,

Mr. Sidney Herbert, afterward Lord Herbert of Lea, Miss Nightingale

undertook the task of organizing and directing this service, which

she performed in a manner universally admired, and which earned her

the personal friendship of the Queen, with many public and private

expressions of gratitude and esteem. A testimonial fund amounting to

$250,000 was subscribed in recognition of her patriotic and benevolent

work, and was, at her special desire, applied to create and maintain an

institution for the training of nurses. Miss Nightingale’s impaired

health, for many years past, has debarred her from active public

exertions but she has continued to study the plans and operations of

those charitable agencies on which she is a high authority, and has

written brief treatises on subjects of much practical importance. Her

“Notes on Hospitals,” printed in 1859; “Notes on Nursing,” in 1860;

and “Notes on Lying‐in Institutions,” and on the training of midwives

and midwifery nurses, in 1871, were of considerable utility. She also

wrote, in 1863, valuable observations on the sanitary condition of

the army in India, and has furnished to the War Office useful reports

and suggestions concerning the army medical department.—_Illustrated

London News._

Painting.

In order to use paints and oils economically, a clear understanding of

their purpose and action is absolutely necessary. Linseed oil is said

to “dry” after being applied. That is only partially true. It rather

oxidizes and changes to a tough, gummy substance not unlike hard glue.

This action is accelerated by the use of “driers,” as they are called.

But in no case does it give the same results as when left to dry of

its own free will. The carbonate of lead or mineral which is added to

the oil gives the color and assists in making up the body. The life of

the paint is the oil, and when it is oxidized, it alone is the binding

element. Upon it depends the durability of the paint. A piece of wood

dipped in linseed oil and hung up to dry, or oxidize, in the air, will

soon become covered with a beautiful translucent film of oxidized oil,

which grows harder daily. It will take a high polish and preserve the

wood. Another piece dipped in carbonate of lead, or mineral, mixed in

turpentine, or any fluid to allow it to spread evenly over the surface,

will when dry have a dead or flat color without polish or body to

bind it together, and the slightest abrasion will remove portions of

it. All painting is done either with pure oils or with the admixture

of a fluid like turpentine, which assists in the distribution of the

mineral, but does not add to the body. When the surface of wood has

been covered with a thick coating of oxidized oil, it can be washed and

rubbed to look clean and polished. Boats, when of a light color, are

often painted with a mixture containing much turpentine, in order that

all marks may be removed with a little beach sand, by rubbing off the

mineral, which is not bound together securely by oil, but only loosely

by turpentine. Car builders now often paint their cars or varnish them

a second time soon after the first, say after about six months’ run.

This gives them a good coat of oxidized oil to withstand the weather

and preserve the wood. A few coats applied within short intervals

produce a fine covering which is very durable and will take a polish

after washing.—_Master Mechanic._

Removal of Chimneys.

An interesting scene was caused recently by the blowing up of the

two immense chimneys on Borsig’s machine works in Berlin. A large

number of spectators were present to witness the ceremony, including

several officers of the army, the trustees of the Borsig estates, and

the employes of the works. Punctually at five minutes past six P. M.,

the signal to “Look out!” was given; then came the word of command,

“Fire!” and at this moment the vast chimney, towering to a height of

say 120 feet 9 inches, quietly collapsed. The noise occasioned by the

fall was not very great, ditches two meters in breadth having been

dug all round the chimney and filled with straw. For blowing up this

colossus, which consisted of 98,000 bricks and was topped with a heavy

iron cap weighing twenty‐five centners, only 24 kilos of dynamite were

employed. Photographs were taken of the chimney before it fell, and

also as it was in the act of falling, by an officer of the Commission

for Experimenting with Explosives. The second chimney standing about

80 feet high, was blasted with gun cotton, of which 35 kilos were

required.

HOMES OF FACTORY OPERATIVES.

The institution of the factory system changed the workshop home of the

domestic system to the home proper by transferring work to the factory.

As a result, the homes of the operatives under the factory system have

undergone a great change, and are still undergoing changes, which are

making the English significance of the word “home” a reality to the

poorest. It is perfectly true that in every large factory town one can

find loathsome dwellings occupied by groups of persons called families.

In most factory towns, both in America and Europe, it is easy to find

dwellings occupied by factory operatives which are a disgrace to the

owners and the municipality. Yet, taking the operative population of

such towns as a class, they are very comfortably housed, and about as

well housed in one country as another. The personal inspection of more

than 1,000 homes of factory operatives leads Mr. Carroll D. Wright to

this conclusion, he having written a special report on the “Factory

System of the United States” for the Census Bureau.

British factory houses being floored with stone, as a rule, present

a cold and cheerless look. The dimensions of the British house are

much smaller than factory houses in America. The tenements of three

rooms have much less space than tenements of three rooms here. This is

generally true of all European factory towns. But the houses of the

operatives are, as a rule, separate ones, the tenement house being

quite unknown except where what is termed the “model workingmen’s

houses” are being tried. The boarding house is not an institution for

factory operatives.

[Illustration: OPERATIVE’S HOUSE AT WILLIMANTIC FACTORIES.]

At Saltaire, near Bradford, the homes of the work‐people are excellent;

rents vary from $30 to $100 per year for three to five room houses. The

houses are neat, tidy, and prettily furnished. At Queensbury, where

John Foster & Son have works, the weavers earn 15 to 18 shillings per

week full run, and the rents are 84 cents per week for three rooms.

Some of the best houses in England are at Copley village, in Halifax,

built by James Akroyd & Sons. They rent three rooms for £10 per year,

and the operatives are helped to acquire a freehold. The Crowleys

at Halifax employ 5,000 people, who have good houses. The houses at

Salford and Manchester are not so good. The factories at Paisley are

excellent evidences of the good influence which arises from proper

interest in employes. The works of the Messrs. Clark and Messrs. Coates

are model establishments and the influence of model works extends to

the houses of the people employed, which are here very comfortable.

Rents vary from 72 cents to $2 per week, according to number of rooms.

In Glasgow no cellarages can now be found. The operatives have gone

to the suburbs, where they have changed their cramped city abodes for

clean and light houses. Belfast, Ireland, is improving the dwellings of

the linen factory operatives. The houses are tidy, and rents are from

48 to 60 cents per week for four rooms. There are houses with flats

in Belfast. In the west and east of Scotland the operatives live very

largely in flats; rents in Dundee and Dunfermline being for two rooms

from $15 to $30 per year, and for three or four rooms from $30 to $50

per year.

Among the most substantial houses for workingmen will be found

those of Herr Krupp, in Essen, Rhenish Prussia. By his system of

employment he has the selection of the best mechanics in Europe. This

system comprehends all the advantages to be found in model industrial

establishments, including excellent tenements and gardens at low

rents. A foreman, a gun‐maker, earning $45 per month, receives four

rooms, a drying place on the roof, a cellar, and a garden for $45 per

year. A workman with wages at 75 cents per day pays $37 per year for

three large rooms, drying place, cellar, and garden. There are fair

tenements, in two or three story blocks, situated in colonies just

outside the towns. For $100 per year, one can obtain a most excellent

tenement of seven large rooms, cellar, garden, etc. The houses in

the colonies are owned by Herr Krupp. In fact, he believes that he

receives better results by owning everything, and by being able thereby

to control the sanitary surroundings of the dwellings of his people.

These colonies, each having its name, are laid out with park, schools,

churches, supply stores, etc. The housing of the single men is on the

barrack plan.

It may be stated that the houses in Great Britain and on the Continent

are of stone or brick, as the locality may afford, and the neat wood

cottage of America cannot be found. It is quite impossible to compare

the houses of European factory operatives with those of the same class

in America. The great mass of the former are, generally speaking, quite

as well housed as the latter, so far as the quality of the house is

concerned; but so far as quantity of room and excellence of living are

concerned, the advantage is with the operatives of America. When the

operative of this country steps out of the boarding or the tenement

house, he steps into an individual home the equal of which cannot be

found in the factory towns of the Old World.

The cottage of the American factory operative, when he sees fit to

occupy one, is superior to the cottage of the workingman of any other

country. It is most gratifying to know that the individual homes are

not only increasing in number in this country, but they are increasing

in influence. In all the leading factory towns this is the course of

progress.

The plates we give on this page represent one of the styles of modern

cottages built by the Willimantic Linen Co., of Willimantic, Conn. With

each cottage is quite a garden of several thousand feet of land. The

rent is from $60 to $125 per year. These houses are located in such a

way as to exhibit variety of styles; that is, two of like architecture

are never placed side by side. The company has a large number of these

houses occupied by operators and overseers. The cuts show the front and

side elevations, and the plans of the two floors. These are given as a

type of the detached workingmen’s homes used in this country.—_Min.

and Sci. Press_.

Gangways v. Staircases.

Mr. A. Lindsay Miller, in the _Building News_, recommends for theaters

and other public buildings the use of gangways instead of stairs.

In public works, especially dye works, they will not use the stairs,

but gain access to the several floors by gangways, with a rise of about

5 ft. in 12 ft. or 13 ft. of length, and any one watching the speed

and ease with which the workers run from floor to floor would at once

understand why staircases are not used. Of course, architecturally,

they have not the dignity of the staircase; but, in theaters and music

halls, dignity is secondary to security. The advantage of the gangway

is easily explained.

In going down a stair, each step, or, in a hurry, each second step,

must be taken, and the slightest mistake throws the person down. In a

stair 12 ft. long, at least six different steps require to be taken.

In the gangway of the same length, a person in a hurry, or in the

excitement of a panic, would take it in two bounds, and with perfect

safety.

ROBURITE—A NEW EXPLOSIVE.

A number of experiments were conducted lately at the works of Messrs.

Heenan & Froude, Manchester, with a new explosive, called “roburite,”

which is manufactured in Germany, and is about to be introduced into

this country for use in blasting operations. The composition and

process of manufacture of this explosive are kept secret, but we

understand that it consists of two non‐explosive and perfectly harmless

substances, of such a nature that they may be stored or transported

without special precautions or restrictions. These two substances may

be mixed together when required, and, in combination, become roburite,

a yellowish compound, which will bear rough handling with safety. We

understand that an intense heat is necessary to explode it. In order to

prove this, the explosive was placed, in the experiments in question,

between two plates, which were freely rubbed together and hammered;

and a small quantity thrown upon a fire was merely consumed, without

exploding.

[Illustration: Fig. 1.]

In order to obtain an idea of the explosive effectiveness of roburite,

eight ounces of the explosive were placed on a plate of the very best

steel, at the point marked A in Fig. 1, which shows the state of the

plate after the explosion. This plate was 3 ft. square by ½ in.

thick, and a bulge of about 1 ft. diam. and 3½ in. deep was caused

by the explosion. Twelve ounces of the explosive were then placed at

A (Fig. 2) on a cast iron plate, 6 in. thick, and weighing nearly

three tons. After the explosion the plate was found to be broken

transversely, in the manner shown in the engraving. Unlike dynamite,

roburite is said to be in no way affected by varying temperatures,

and if duly protected against damp, it may be kept for years in any

climate, without its efficiency becoming in any way impaired. It is

also claimed by the manufacturers that roburite has an explosive force

greater than dynamite by at least 25 per cent.

[Illustration: Fig. 2.]

In exploding, roburite does not produce noxious gases, and, therefore,

may be used without intermission, while the poisonous gases given off

by dynamite often necessitate the stoppage of work, in some cases

for a considerable time. This new explosive is applicable for use

in mines and quarries, and for torpedoes and blasting operations

generally.—_Industries_.

Iron Beams In Place of Wood.

Speaking of the large apartment house in New York lately condemned for

dry rot (see illustration last November number of this paper), the

_American Architect_ says: A few of the floors were of spruce, and

these, as might be expected, had resisted the rot much better than the

hemlock, and were still sound, but the construction ought certainly

to be changed. In view of the dangers from this source which attend

efforts to provide fire‐resisting floors of wood, it would seem that

something might be done with light shapes of rolled iron beams. We have

seen rolled floor beams used in Paris nearly as light as wooden ones

of the same depth, and a tier of these, deafened with mortar on wire

in the French manner, and wire‐lathed underneath, with a wooden floor

over, would cost little more than a solid mass of wooden beams, and

would be proof against rot as well as fire.

BATHING ESTABLISHMENT AND CASINO IN VITTEL (VOSGES). BUILT BY CHARLES

GARNIER, ARCHITECT, OF PARIS.

The casino is built of plastered quarry stone, with the exception of

the socle, the balustrades, and the pillars, which consist of gray

Vosges sandstone. The facade is ornamented with mosaics, and the roof

is covered with slate of two colors.

[Illustration: BATHING HOUSE AND SALOON AT VITTEL—CHARLES GARNIER,

ARCHITECT.]

The bathing establishment is colored in Moorish style. Red brick bands

in the socle, as well as the faience and mosaics in the main cornice,

stand out artistically from the gray plaster of the walls. The roof is

covered with red tiles.—_Architektonische Rundschau_.

The Back Yard.

Our immediate ancestors had their farm house, with its necessary

accompaniment of granaries, barn, etc. We move to town and build our

shingle palace or brick mansion, with its large front show window, in

which the well preserved, gilt edged family Bible and the Rogers group

have it which and t’other for supremacy—and set up in our back yard,

to represent the outbuildings of our ancestry, a privy, a pile of

slabwood, generally as dumped, a few barrels, perhaps a cheap stable.

Not then satisfied with the amount of decaying wood about the premises,

we lay a lot of wood walk.

Walking along the avenue, we see a pretentious residence. It must be

occupied by people of great refinement, for is not the most prominent

room in the house the library, the whole street side taken up with

an immense bay window, the glass reaching nearly to the floor? How

splendidly it was lighted as we passed last night! What elegant sets

of books on the shelves! Plenty of pictures, too. Let us to‐day take

a look at the back yard. Why do not these people board up the windows

at the back of the house? Here is a well with a dirty puddle by it,

the pump standing on a rotting platform; hard by some kitchen garbage,

farther on ashes, and so it goes, the whole rear of the lot so bad as

to discourage vegetable life even. It is mercifully screened in part

from the general view by a high, unpainted board fence, against which,

now and then, a weed or tuft of grass grows. Where is there better

field for the crusade?

The rear of the house and the outbuildings, though not so expensively

finished, have a right to be carefully and artistically done. A

woodshed is not a nuisance if inclosed, well boarded and painted, and

the wood kept inside. A privy has no right to exist. If there be no

proper system of drainage in the house for a water closet, partition

off an earth closet from the woodshed or stable. Tasteful, well cared

for outbuildings and fences are not only not an offense to the artistic

sense, but are rather pleasing, indicating thrift, tidiness, and

comfort. But when we consider the opportunities they offer for the

support of the vine morning glories, sweet peas, nasturtiums, climbing

roses, and like forms of plant life, what a joyous recompense for so

little labor and care. Then all the available back yard space that is

not used for walks, drives, etc., should give either vegetables or

flowers—minister to the comfort or culture of the family.

Listen to people who lament the bad influences of street associations

upon the children. Yet they say, very reasonably, the children must

have outdoor air, etc., and they have never considered but that the

only alternative from the housing of the children is the freedom of

the streets. They do not know what moral education is contained in a

few feet of ground, congenial work for the hands, and the prettiest of

life development studies for the mind. Give each of these street‐loving

children a flower bed, a small set of garden tools, some flower seeds,

and what help and advice they need, and note if there be not germs

of nobler thoughts and desires taking root at the same time in their

fertile natures. But—to moralize a little—there is a kinship between

the ornamented front and disgraceful rear of a residence and the

fine clothes and the false heart of the wearer, and we fear that the

majority of people who inhabit that sort of residence would rather risk

some contamination of their children’s characters than to see their

faces, hands, and clothes besmeared with Mother Earth.

The back yard of the future will be a bower of flowers and greenery and

the leisure hour resort of the family.—_N. W. Architect_.

Thomas Ustick Walter.

Thomas Ustick Walter died at his home, in Philadelphia, on October 30,

aged eighty‐four years. He had been for some years president of the

American Institute of Architects.

His first principal work was the new county prison, in 1831, now

generally known as “Moyamensing Jail.” In 1833 he made the original

designs for Girard College, and was sent to Europe by the building

committee of the institution. His tour through the principal countries

was made for the specific purpose of the study of the principal

buildings of the old world. Upon his return he took charge of the

college buildings, which were finished in 1847, in accordance with his

suggestions, when he was also made one of the directors of the college.

Mr. Walter’s next great public work was the break‐water at Laguayra

for the Venezuelan government. In 1851 his design for the extension

of the national capitol was adopted, and he was appointed government

architect. He removed to Washington, where he designed several

prominent public buildings, among them being the wing added to the

Patent Office in 1851, the reconstruction of the Congressional Library

building, which was destroyed by fire in 1851, the extensions of

the United States Treasury building in 1855, and the Post Office in

the same year, the dome of the national capitol, and the government

hospital for the insane.

Pine Woods.

The sights and sounds of pine woods, the comfort and delight of walking

in them, cannot be half told in a short paragraph. They are also as

sanitary as they are pleasing and beautiful. It is said that the air

of the Black Forest does more to revive and cure weakly patients than

gallons of medicine; and from experience of the odors of pines at

night, or in the early morning and dewy eve, I should say they were not

only antiseptic, but strengthening as a dose of quinine. The living

leaves, as well as the dead and slowly decomposing needles, redolent of

healing and strengthening odors, bring back the color to pale cheeks

and strength to semi‐exhausted constitutions.

The shelter of pine forests is also perfect. No matter how the wind

thunders and roars among the tops, calm prevails on the surface of

the ground. Just as the waves of the ocean are, after all, limited to

its surface while a perpetual calm rests on its deeper depths, so the

turmoil of the storm exhausts its force on the tops of the trees, while

the base of the boles are hardly moved by it. Hence the superlative

value of pines in masses for shelter. The shelter of a large pine

wood is unique in character, providing a local atmosphere as genial

as it is pleasant. The elasticity of the dead needles seems to get

into one’s spirits, and enables one for the nonce to bid adieu to the

cares and the ills of life. One saunters along under the shadow of

tall pines without fatigue, and can rest on the clean, sweet carpet of

dead needles and leaves with little fear of noxious weeds, insects,

or malaria; and the whole air is deodorized and charged to the full

with health‐giving properties by the odor‐distributing pines, that not

only provide warmth and shelter, but health, to all who walk under

or linger among them. Pine woods in England are mostly too small to

furnish to the full all these advantages; but the black forests of

Scotland, Germany, Denmark, Sweden, and Russia are massive enough to

furnish shelter, shadow, rest, and health to those wise enough to seek

for either amid their grand trunks or under their dense, dark masses of

branches and leaves.—_The Garden_.

SKETCH FOR A COTTAGE.

We give from the _Architectural Era_ the floor plans and perspective

sketch for a cottage which presents a number of attractive features.

This house might be well built for $5,500, and perhaps less, depending

on the locality and style of interior finish.

How We Have Grown.

When the history of the past seven years comes to be written, they

will stand as years of the most marvelous expansion ever known in our

history. Two of them, 1884 and 1885, were held as they passed to be

dull years, but even these included great growth, and were a period

of industrial readjustment rather than liquidation. The population of

this country has not increased more than a fourth since the census

of 1880, but house building, as an industry, has more than doubled,

the number of common brick made in this country having increased from

3,800,000,000 to 7,000,000,000, worth $49,000,000. As the lumber trade

has increased in less but large proportion, and iron production has

risen over one‐half from 4,300,000 tons in 1880 to 6,300,000 in 1886,

it is certain that the past seven years have seen the most active

building ever known in this country. Chicago uses one‐seventeenth of

the brick made in the country, and if its building represents the same

share of the cost of house erection of all sorts in the United States,

fully $2,000,000,000 have been spent on buildings in this country in

the last seven years. As about the same sum will be reached by adding

the building in the leading cities and estimating for the rest of the

country, the truth is probably not far from these figures, which are

under rather than over the mark. The railroad building since 1880 has

cost, at $50,000 a mile, $2,700,000,000. This makes $4,700,000,000, or

about one‐tenth of the national wealth in 1880, turned into railroads

and buildings in this country. As the residence and business real

estate of the country, including water power, was valued in the census

of 1880 at $9,881,000,000, and the railroads at $5,500,000,000, we

have added one‐half to the cost of the latter and one‐fifth to the

former in seven years, although the railroads represent the accumulated

construction of fifty years, and the buildings are spread over an even

longer period in their erection. This enormous increase has taken place

without adding a bale to the cotton to be carried or a bushel to the

grain raised. No more pork is produced now than in 1880, and the number

of sheep is no greater now than then. Great increase has been made

in cattle raised for food, in fruits, and, on the average, in canned

goods. Coal, taking bituminous and anthracite together, has increased

one‐half from 70,000,000 to 106,000,000 tons. Copper has advanced in

output from 27,009 tons in 1880 to 69,800 in 1886, and about the same

this year. A great advance is true of nearly all mineral products, but

in agriculture the United States has made little or no progress in

product in the last seven years, but a great advance in acreage or the

cost of cultivation.—_Philadelphia Press._

A Good Suggestion.

Charles Hardy, in the _National Builder_, says: Underestimating means

working for nothing and forcing others to do the same; it means

impoverishment and poor work. The contractor has himself and his family

to maintain, and the temptation is great to get out by doing poor work.

I would suggest that every contractor purchase an account book large

enough to enter, line by line, upon a single page, every item of his

estimate—giving quantity, price, and labor for each item. Let him

leave opposite to this page a blank page, on which he may enter, on the

corresponding line opposite, the actual amount of labor expended upon

the item, and he will thus be able to see the result of his contract.

A TOWER of VICTORY has been erected on the grounds of Washington’s

Headquarters, at Newburg, N. Y., at a cost of $35,000. It affords

beautiful views of the Hudson, the Highlands, and the surrounding

country.

THE JOHN CROUSE MEMORIAL COLLEGE FOR WOMEN.

We take pleasure in presenting to our readers an illustration of

the John Crouse Memorial College for Women, which it is proposed to

erect on the hill west of the Hall of Languages, Syracuse University,

Syracuse, N. Y. This edifice is to be the gift of one of the wealthiest

and most prominent citizens of Syracuse, Mr. John Crouse. The donor of

this magnificent gift well deserves to be held in grateful remembrance

by every friend and well wisher of the Syracuse University, as well

as by the students and faculty. It is proposed to make this building

a model one in every respect, and neither pains nor money are to be

spared to render it the most perfectly equipped college to be found in

the country. The structure is to be five stories in height, to be built

of East Long Meadow brownstone, and to cover an area of nearly two

hundred feet square.

In this connection a brief historical sketch of Syracuse University may

interest our readers.

The college now known as Syracuse University had its origin in Lima,

a pretty little village in Western New York, but quite out of the

way, and not easy of access. It was then called Genesee College,

and the first gathering of faculty and students occurred on Monday,

June 9, 1851. The faculty consisted of Benjamin F. Tefft, D.D. LL.D.

and Professors Houghton, Douglass, Whitlock, and Alverson. On June

12 of same year, the Rev. B. F. Tefft was inaugurated president of

Genesee College, and on July 10 the names of thirty‐eight students

were enrolled on the college register. November 5 saw the faculty

increased by the addition of Professors Hoyt and Fowler. The college

thus organized continued with varying fortunes until July 7, 1871, when

it disbanded. In 1866 the subject of removing the college from Lima

began to be agitated, and the idea of a central university for the

Methodism of New York was first publicly announced in the _Northern

Christian Advocate_, during the year 1873. From this time forth the

new enterprise met with great favor on all sides, except with the

citizens of Lima, who were reluctant to see the withdrawal from their

midst of their principal attraction, to which we may well believe they

had become greatly attached, and who procured an injunction against

its removal. Prominent members of the Methodist Central Conference

were nevertheless commissioned to carry forward the good work, and

substantial aid was soon forthcoming. Syracuse, being the most central

city in the State, was finally settled upon as the most appropriate

home for the new college.

[Illustration: ARCHIMEDES RUSSELL, Architect, Syracuse, N. Y.]

The site now known as University Hill was secured, plans made by the

well known architect, H. N. White, were adopted, and July 19, 1871,

the contract for building the Hall of Languages was let for the sum

of $136,000, and Syracuse University became an assured fact. The

corner stone of the Hall of Languages was laid on August 31, with

impressive ceremonies, and the faculty of the College of Liberal

Arts was inaugurated. On September 1 the college opened in the Myers

block, which had been secured for the use of the university, and here

the sessions were held until May 1, 1873, when the Hall of Languages

being completed, it was on that date occupied for the first time.

During the year 1871 the plan for a medical college in connection

with the university was adopted, and its first commencement exercises

were held February 12, 1873. When the Hall of Languages was erected,

other buildings were contemplated at such time as the finances of

the university should admit of their realization. The institution

has struggled along, sometimes meeting with reverses, but now and

then being fortified and strengthened by the reception of substantial

encouragement from some of its many and devoted friends. Now at last

the wheel of fortune has suddenly turned in its favor, and it finds

itself at the flood tide of prosperity, with the prospect before it of

a long and honorable course of usefulness and well deserved success.

University Hill commands a magnificent view of the belt of hills which

girdle the city, with Onondaga Lake set like a sparkling gem in the

distance. Upon the west hill an observatory has just been erected,

and near the Hall of Languages a suitable building is in process of

erection, for the accommodation of the fine and valuable library which

has been generously bestowed upon it by one of its friends. Syracusans

are proud of the University, and they, in common with its hosts of warm

friends throughout all parts of the country, rejoice in the evidence of

its well merited prosperity.

The alumni of Syracuse University have members not only in almost

every State in the Union, but count among their number graduates

from Canada, England, Mexico, San Domingo, Brazil, China, India, and

Japan.—_Architectural Era_.

How a Marble Statue is Made.

Mr. John A. P. Macbride, sculptor, who was introduced to a large

audience, chiefly of workingmen, by Sir James Picton, recently gave a

practical lecture on the above subject, at the Rotunda lecture hall,

Liverpool. After giving a sketch of the art and its great antiquity,

the lecturer drew a profile in chalk on the blackboard, which he filled

in with clay, and proceeded to demonstrate the building up and modeling

of a portrait bust of soft clay. He stated that there was a general

and erroneous opinion that in taking a portrait bust it was necessary

to take a cast of the face. This was a mistake, for the head lost all

the spirit and go by such a mechanical process that should distinguish

an artist’s work. The truth was not always that which appeared to be

true, and the sculptor had to convey some idea of the character as well

as of the mind of the sitter; and a man who knew his work ought to be

able to do so with his fingers. Carving was a secondary consideration.

The lecturer then explained the process of pointing a marble statue.

In this process, the model and the block of marble were each fixed on

a base called a scale stone, to which a standard vertical rod could be

attached at corresponding centers, having at its upper end a sliding

needle, so adapted by a movable joint as to be set at any angle and

fastened by a screw when set. The sculptor having marked the governing

points with a pencil on the model, the instrument was applied to these,

and the measure taken. The standard being then transferred to the block

base, the pointer, guided by this measure, cuts away the marble, taking

care to leave it rather larger than the model, so that the general

proportions were kept, and the more important work then left for the

sculptor’s hand.—_Building News._

About 5,500 buildings have been rebuilt and improved in Charleston,

S. C., in the year since the earthquake, and 270 new buildings have

been erected. This has been a busy year with mechanics and builders at

Charleston, and about $3,500,000 has been expended in this work.

A Great Building.

Mr. J. L. Smithmeyer, architect of the Congressional Library building,

states in his first annual report that the Congressional Library

building when completed will be the largest structure in Washington,

with the exception of the Capitol. It will cover 111,000 square feet of

space.

In a building of such magnitude and importance, every step in the

progress of the work must be carefully considered, lest fatal mistakes,

due to hasty construction, should occur. It was deemed of the utmost

importance to test every foot of ground supporting the foundation

walls. For this purpose a traveling testing machine was constructed,

which will give an accurate test of the entire soil. The tests thus far

made have been most satisfactory, the soil standing a maximum pressure

of 13·5 tons to the square foot, only 2·5 tons being required. These

tests will be continued until the foundations are laid.

The method of testing the soil and putting in the concrete foundations

may be briefly described as follows: First, the trench excavations are

made by the contractor to the width and depth required by the plans,

the bottom of the trenches being made perfectly level. Then the testing

machine, consisting of a car bearing the required amount of weight in

pig lead for making the tests, is placed in the trenches upon iron

rails, which rest upon four cast iron pedestals, the latter being set

four feet apart each way, each pedestal covering one foot of ground.

Thus, one‐fourth of the entire weight borne by the car rests upon

each one of the pedestals, and the precise weight sustained by each

square foot of ground is exactly determined. The soil being thus tested

as to its resisting strength, is then ready to receive the concrete

foundations.

Proportions of Rooms.

There are few objects connected with our art that have been more

frequently dwelt on by those who have undertaken to be our guides and

monitors than the right proportions to be given to rooms. Vitruvius

led the way, and subsequent theorizers have laid down, sometimes very

dogmatically, their views of just proportions. I find, however, in the

actual practice of the ablest men such extreme diversity, and I observe

pleasing effects producible by the adoption of such widely different

proportions, that I find myself, I confess, much inclined to be

somewhat incredulous of all these theories. Certainly if beauty could

be thus reduced to a formula, and the proper relation indisputably

established between the length, breadth, and height of every room,

a royal road would be cleared for us, which would be at least very

convenient both to those who teach and to those who learn. I fear I

can scarcely hope to furnish you with such a desirable help in your

studies. I find rooms of universally admitted beauty, yet of almost

every geometrical figure. I have heard of the room in the museum of

Florence, the Tribune it is called, which contains the Venus di Medici,

spoken of in terms of rapturous approval for the beauty of its form

and proportions. This saloon is an equilateral octagon on plan. I have

known square rooms greatly admired—such, for example, as the saloon in

Cobham Hall, which is usually pointed to as one of the _chefs‐d’œuvre_

of Inigo Jones. Who is there that is not charmed with the proportions

of the Pantheon at Rome? This, you know, is circular. The classical

teacher of our art, Vitruvius, seems to contemplate only rectangular

forms, and directs us to adapt the double cube and the cube and a half,

whether for a temple or a triclinium.

The Sistine Chapel, attached to the Papal Palace, upon which the best

art of Italy in its best days was expended, is a triple cube, viz.,

133 by 44. While of modern French, Italian, and English teachers, each

seems to have his own special favorite proportion. The truth I believe

to be that, so bounteously have we been endowed, and so liberally have

the laws of beauty in form and proportion been framed, there exists

in fact an endless variety of beautiful forms and proportions. My

impression is that it is as little consistent with truth to lay down

any one definite form or proportion as the best as it is to extol any

one particular curve as the line of beauty. I believe that there are as

many pleasing proportions to be given to rooms as there are pleasing

harmonies of color and sound. The purpose of a room must always be an

important guide in determining the form and proportions to be given

to it. If planned so long in proportion to its width as to remind us

of a passage, it loses its distinctive character, and creates a false

impression, which it can never be good art to do. It is indeed obvious

that a consideration of the special fitness of a room for its destined

uses must always greatly influence its proportions. The octagon form,

so much affected by our ancestors in planning their chapter houses,

owes its origin probably far more to the propriety of that form for a

chamber intended for the convenient assemblage of the members of the

chapter sitting in council than to any intrinsic architectural beauty,

however unquestionable that beauty may be.—_S. Smirke._

The _Firemen’s Herald_ says fire protection, like charity, should begin

at home. However efficient may be the public service against fire, a

single bucket of water properly administered may stop a fire that all

the efforts of the brigade would be unable to quench, and besides, the

jet of a powerful engine is as destructive in its way as fire to all

perishable articles within a room, such as furniture, pictures, and

bric‐a‐brac.

Plants for Room Decoration.

The universal custom now prevailing in most establishments of having a

few plants in addition to cut flowers dotted about the different rooms

induces me to write a short paper thereon, not only because it has

developed into a very important part of the gardener’s work, but it

likewise requires a fair share of taste in the arrangements, as well as

suitable plants for the purpose. Generally speaking, each room being

differently furnished will require a different class of plants for

its adornment, but, as a rule, plants with stiff, upright growth are

objectionable to the eye, as they do not hide the pot or stems unless

others of a dwarfer growth are associated with them; therefore they

should only be used when possessing special features either in flower

or foliage. Too many plants in a room are objectionable, because they

detract from rather than elevate or enhance the effect, especially if

the room is elaborately furnished. For instance, plants assigned to the

front hall or corridor would be unsuitable in a drawing room or boudoir.

Another important matter to study is the various kinds of receptacles

provided for the use of plants. These vary in size and shape greatly,

but are generally of a fanciful, elaborate, and artistic design, and

the plants for these should be selected with the greatest care and

taste, so as to add a completeness and finish, and in no way hide or

diminish the effect of their appearance. I have often found, however,

a great difficulty in getting plants to go in them without taking

them out of the pots, and in many cases I have found it necessary to

reduce the ball of roots in order to fit the latter in properly. This

quite ruins the plant, for, in the case of choice or delicate growing

subjects, it is almost impossible for them to recover. But in order to

meet this difficulty, it is advisable to make a selection of plants,

grow them in suitable sized pots, and use them for no other purpose.

To do this it requires a sufficient number for three changes; say, if

twenty plants are required at one time, sixty should be grown, and

duplicates of all to be grown to follow on.

The atmosphere of rooms is generally dry, though warm, and impregnated

with gas and other enemies to plant life. So different is all this to

the healthy atmosphere of a plant house, that it is necessary that

every plant used should have completed its growth, or some injury will

follow. Take the different varieties of adiantums, for instance. If

used for the decoration of rooms in a growing state, the young fronds

would most certainly be injured; yet, when properly prepared, there

are no more popular or suitable plants for the purpose, and they can

be grown to a useful size in small pots. Nephrolepis exaltata, though

not so choice as others, is a most handsome fern to use. Its long and

gracefully drooping fronds are an ornament in any position, while many

of the Pteris family have a fine and graceful appearance, and may be

used freely. Nice plants of Spiræa japonica with or without flowers are

very ornamental. The different sorts of lycopods make perfect plants

for small vases, as also do the artillery plant (Pilea muscosa) and

the little Caladium argyrites. In fact, there is no lack of either

foliage or flowering plants suitable for a tasteful arrangement either

in a drawing room or boudoir, while for more commodious places, such

as the entrance hall, corridor, or staircase, and where larger plants

are admissible, there is the beautiful Caladium esculentum, with noble

foliage and which stands well, several sorts of palms, the larger

fronded ferns, curculigo, Ficus elastica, Hibbertia volubilis, and the

calla or Ethiopian lily, all of which have a reputation for retaining

their beauty better than many others, and therefore should be grown

for the purpose. But to avoid as little injury as possible, frequent

changes are necessary, and it is a very good rule to water every

plant well before it is used, and when it again needs water change it

for another. Let all pots and plants be kept very clean, and avoid

letting the plants remain long enough to make growth in the different

positions, for such growth, when brought out to the light, is generally

very weak.—_Thomas Record, The Garden._

THE WAINWRIGHT HORIZONTAL FEED‐WATER HEATER.

We illustrate herewith the Wainwright Horizontal Feed‐Water Heater,

adapted for use in a horizontal position under the floor of an engine

room, or where the head room is limited. The feed water enters at the

lower opening marked “feed,” fills the body of the heater, and having

been heated by the exhaust steam surrounding the tubes, passes to the

boiler at upper opening marked “feed,” the exhaust entering at either

end. A drip pipe, as shown, is provided for escape of the water of

condensation, and a hand hole for washing and cleaning. It will be

seen that this heater contains a large body of water well disposed to

receive heat, the tubes, being of corrugated copper, present 50 per

cent. increased heating surface over plain tubes of the same length,

while at the same time five times the strength is added, and owing to

their property of expansion and contraction, all danger of the ends

pulling out or the joints working and leaking is eliminated. This

property of expansion and contraction also prevents any accumulation of

scale and sediment.

[Illustration: HORIZONTAL FEED‐WATER HEATER.]

These heaters are manufactured by The Wainwright Mfg. Co., 65 Oliver

St., Boston.

The Charter Gas and Gasoline Engine.

This gas engine, manufactured by the Williams & Orton Manufacturing

Company, of Sterling, Illinois, possesses various features that must

commend it to the attention of all interested in the production of

power from gas. It is characterized by great simplicity, having no

gearing, so that it is practically noiseless. It has a power and a

supply cylinder, one placed over the other, and each working or worked

by its own crank. An impulse is given at every revolution of the wheel,

and by the governing device the amount of gas consumed is regulated in

proportion to the work done. The ignition valve is easily accessible,

and needs no adjustment on starting the engine. It can be used either

for gas or gasoline. For the latter, a few drops are aspirated at each

stroke into the cylinder, where mingling with the air they form the

mixture for ignition. The gasoline can be kept in a tank outside the

building, and is subjected to no contact with the flame until it has

been thoroughly vaporized and has entered the working cylinder.

AN IMPROVED DOUBLE SURFACE PLANER.

[Illustration: GLEASON’S DOUBLE SURFACE PLANER.]

A four‐roll machine that is simple and durable, and all geared with

the most improved extension gearing, is shown in the accompanying

illustration, as made by Messrs. E. & F. Gleason, manufacturers

of improved wood tools, American Street and Susquehanna Avenue,

Philadelphia, Pa. Both heads are driven with one counter, and only two

belts are required, the adjustment of bed and control of feed being

both on left‐hand side of machine, at B C, within immediate reach

of the operator. The bottom head is quite as easy of adjustment as

the top head, having large screws, F, one at each box, to regulate

cut or chip and keep it in line with bed and top head, both heads

having self‐oiling boxes. The machine will double‐surface stuff from

one‐eighth inch to six inches in thickness. It occupies a floor space

of about four feet by forty inches. The counter shaft has patent

self‐oiling hangers and patent self‐oiling loose pulleys.

Foundations in Wet Ground.

A new method of making foundations in wet ground has been devised by M.

Bonnetond, a French military engineer. His plan is to bore a hole 10

ft. or 12 ft. deep and 1½ ft. in diameter in the damp ground, and in

this a series of dynamite cartridges are placed, and finally exploded.

The expansion of the gases generated drives the water far out beyond

the sides of the hole, into which it does not return for at least

half an hour. The time thus gained is utilized in rapidly excavating

the cavity, which is then filled with a cement concrete, which sets

before the return of the water. The method has been adopted in the

construction of a fortified enceinte at Lyons, and is said to have led

to very rapid work.

HOW TO MAKE A CHEERFUL FIRESIDE.

In the accompanying illustration is shown one of several forms of

arranging artificial sticks or logs in a fireplace for burning gas,

to give a close imitation of a blazing wood fire, which has been

patented and is made by Henry P. Dixon & Co, of 1330 Chestnut Street,

Philadelphia. Several other forms of logs and grouping are also made,

the sticks and the logs being colored to resemble wood, and having

fixed between them splints of asbestos, which become incandescent when

in use, so that when the gas is turned on and a match applied to the

small jets arranged to the best advantage over and between the logs, it

gives the appearance of a first class wood fire. These artificial logs

are made of material not injured by the flames, and are designed to

last a life‐time without cracking or breaking, the gas being supplied

through a brass union fixed in the back of each log, through which

connection can be readily made by rubber tubing or otherwise to the

nearest gas pipe. A good, cheerful fire, which makes neither dust,

dirt, nor ashes, is thus ever ready at hand and available by simply

turning on and lighting the gas, the flow of which is regulated as

desired.

[Illustration: ARTIFICIAL LOGS FOR FIREPLACES.]

The Sounding Board in St. Paul’s Cathedral.

The form of the sounding board is, I think, a novelty, but I am led

to believe that it is an approach to the true form for the purpose.

Flat sounding boards have been most commonly tried, but they are now

generally discarded. A parabolic sounding board behind the preacher

has been used with a certain effect, but the advantage is limited to

those in the direction of the axis of the curve; and in these cases,

action and reaction being equal, the preacher can sometimes hear the

criticisms of his audience, if any should be uttered tolerably loud

in the proper direction. Besides which, a shell of this description

would have had little effect in stopping the objectionable echoes. To

meet these difficulties, a curve was selected which has the property

of distributing uniformly in every direction so much of the preacher’s

voice as can be advantageously reflected. The figure is hyperbolic,

the axis being perpendicular over the preacher. The diameter is ten

feet, and so much of the voice it receives is reflected as if it came

from a point about four feet from the preacher. It would be interesting

to know, but I am not aware that sufficient experiments have been

made to ascertain, what amount of sound is reflected from a given

material. The harder the material, obviously the better the result.

In this case hard organ pipe metal has been used. I observed a marked

increase of audibility of the voice at a place where the assistance

of the reflected sound is obtained over a point equidistant from the

pulpit, but too high to receive the reflected wave from the sounding

board.—_F. C. Penrose._

THE POPULAR “FORTUNE” HOT AIR FURNACE.

A hot air furnace that is designed to include all the good elements

of the best styles of modern construction, and is especially adapted

for suburban houses, is shown in the accompanying illustration.

It is manufactured by Messrs. Thomas, Roberts, Stevenson & Co, of

Philadelphia, in four sizes, and has clinker‐cleaning, shaking, and

dumping grate, upright lever for shaking the grate, improved dust

flue and check draft, improved cylinder, with and without drum heads,

and extra large radiating surface, being durable and cheap, while

economical in use. These furnaces are made at a moderate price, without

any expense being put on for mere show, and thousands of them are in

use in nearly all parts of the country.

[Illustration: THE FORTUNE HEATER.]

Not Defective Plumbing.

It many times so happens that plumbing is found a ready excuse for

filthy people to place the blame upon “defective plumbing,” while

in reality it is other defects that are the real cause. There are

many things to take into consideration besides faulty plumbing. You

should ask yourself: Is your cellar pure? How many germs of disease

are lurking there because you have failed to properly drain and

ventilate it, and remove the decayed vegetation and other impurities?

And the well or spring; how much filth, unseen or unrealized though

it be, is permitted to enter there, until at last it enters your life

blood and becomes a part of your being, bringing you to an untimely

grave?—_Plumbers’ Trade Journal._

AN IMPROVED HAND AND FOOT POWER BAND SAW.

A strong and well made band saw machine, to be run by foot or hand

power, is shown in the accompanying illustration, and is manufactured

by Messrs. J. M. Marston & Co., of No. 3 Appleton Street, Boston, Mass.

The table is 18 × 21 inches and 42 inches high, and is adjustable for

cutting on a bevel. There is an adjustable guide for the saw above and

below the table, the saw pulleys are 16 inches in diameter, and the

driving power is by means of gears, all shafts being of steel. The

upper saw pulley has an adjustment to tighten the saw and bring it in

line with the lower saw pulley. The power machines are from the same

pattern, and are arranged with driving shaft and pulley on lower part

of the frame, and tight and loose pulley on lower saw shaft, so that

it can be belted direct from main shafting without counter shaft. The

machine is a very easy‐working one, cutting some four times as fast as

a gig saw with less power.

[Illustration: MARSTON’S BAND SAW.]

The circular saw machine made by the same firm has its center part of

iron, with grooves planed for gauges to slide in, which allows very

fine and exact work to be done on the machine. There is a collar on

the arbor, so that any endwise wear can be taken up, and the gears are

accurately cut from solid iron. The aim of the manufacturers has been

to make a simple, strong, accurate, and durable machine, such as can be

put to hard work without injury, some of their saws having been in use

for fifteen years without needing repairs.

COMPLETE OUTFITS for CONTRACTORS and BUILDERS.

[Illustration: Woodworking Machines.]

Machines for ripping, cross‐cutting, scroll‐sawing, mortising and

tenoning, forming edges, grooving, gaining, rabbeting, cutting dadoes,

and turning. Builders use our Hand Circular Rip Saw for the greater

portion of their ripping in preference to carting their lumber to a

mill five minute’s drive from their shops. The same is true in regard

to scroll sawing, mortising, tenoning, cutting stuff for drawers,

boxes, etc. Builders using these machines can bid lower and save more

money from their contracts than by any other means.

[Illustration: Mortiser and Circular Saw.]

=Read the Following Letters from Builders:=

CLARENCE F. LEE, carpenter and builder, Morristown, N. J.,

says: “I have had one of your Hand Circular Rip‐Saws for about three

months, and am much pleased with it. Have done the ripping for 15

houses in that time, which is over forty miles through inch boards.

Have ripped as high as 3‐inch plank. Table is also good for rabbeting;

having rabbeted all jambs and sawed all drips for 200 windows.”

ALEX. SHIELDS, Lima, Ohio, says: “A few days since we had some

150 small drawers to make for a drug store; the steam power mill wanted

50 cents each for making them. With my foot power machinery I made

them, and saved $25 above good wages on the job.

If desired, these machines will be sold =ON TRIAL=.

The purchaser can have ample time to test them in his own shop and on

the work he wishes them to do. Descriptive Catalogue and Price List

as easily as a very light one. Applied to old windows as readily as to

new, without altering frame or sash. =Will last a lifetime.=

HINTS TO CORRESPONDENTS.

=Names and Address= must accompany all letters, or no attention will be

paid thereto. This is for our information, and not for publication.

=References= to former articles or answers should give date of paper

and page or number of question.

=Inquiries= not answered in reasonable time should be repeated;

correspondents will bear in mind that some answers require not a little

research, and, though we endeavor to reply to all, either by letter or

in this department, each must take his turn.

=Special Written Information= on matters of personal rather than

general interest cannot be expected without remuneration.

=Scientific American Supplements= referred to may be had at the office.

Price 10 cents each.

=Books= referred to promptly supplied on receipt of price.

=Minerals= sent for examination should be distinctly marked or labeled.

(1) G. W. B. asks: 1. What kind of cement used, and how to cement gum

face on band saws? A. Ordinary rubber cement, such as you can purchase

at any of the rubber stores, will answer your purpose. 2. Is there

anything to be put in glue to prevent moisture from disturbing the

joints in patterns? A. A little bichromate of potash put into your glue

will render it insoluble, after exposure to light. 3. Is there anything

to prevent shellac used for patterns from getting dark before using

after it is mixed some time? A. We know of no way to prevent this.

(2) W. S. C.—In closed circuits for steam heating, the pressure of the

steam along the flow pipes and in coils in well arranged systems is so

nearly equalized with the pressure in the boiler, that it requires but

small elevation of the water of condensation in the return pipe above

the water level in the boiler to allow of its return by gravity. In

this system all of the radiators should be not less than from 1 to 5

feet above the water level in the boiler, according to the complication

and extent of the circuit. The air is discharged at the radiators, and

no waste of water is necessary.

(3) E. H. S.—Coal tar alone with gravel and sand for sidewalks does not

dry well. Asphaltum with equal parts of coal tar melted together and

sprinkled upon the mixed sand and gravel that has been made hot upon

an iron plate (the mixing to be done in a large pan of iron), putting

no more asphalt and tar upon the sand and gravel than will just make

it stick together; then dump into place while hot, spread quickly, and

beat level with a ram or heavy roller. Dust over the surface with fine

sand before rolling or beating, to prevent the material from sticking

to the roller or beater. This operation requires a little care and

experience as to just the amount of asphalt and tar for a given measure

of sand and gravel, and also for the proportions of sand and gravel

required to make the best pavement. Sometimes a thin bed of broken

stone is laid as a foundation. Also a thin bed of coarse gravel is

sometimes spread before dumping the hot mixture.

(4) J. C.—A first class ice boat, sailing on first class ice, will sail

from three to four times faster than the wind that drives the boat. For

example, a wind having a velocity of fifteen miles an hour will drive

the boat at the rate of from forty to sixty miles an hour.

(5) T. H. G. writes: I have a mahogany table which has been varnished

and has ink spots on it. 1. By what means can I get the varnish and ink

off, in order to rub on an oil finish? A. The ink spots can be washed

off with water and the varnish with alcohol. 2. What is best to polish

carved brass? A. Polish with rotten stone and oil, alcohol, or spirits

of turpentine. 3. What will remove water stains from polished marble?

A. Mix quicklime with strong lye,

——THE——

“Timby Burglar Proof Sash‐Lock & Ventilator.”

=PATENTED MARCH 29th, 1887.=

=MEETS A LONG FELT WANT.=

It is manufactured from the best MALLEABLE IRON and BRONZE METAL.

[Illustration: FIG. 1.

Section of Frame with Lock applied.

Thumb piece moved upward releasing upper sash.]

Is very simple in construction, strong and durable, absolutely Burglar

Proof, and a perfect ventilator; Automatic in action, easily applied

to any window, as it adjusts itself to varying thicknesses of Sash, or

inside stops.

Only One Lock is Required for

=A WINDOW.=

As it controls both Sash perfectly, bolting either or both securely in

any position desired, thereby affording means for perfect ventilation,

and at the same time absolute security against Burglars and Sneak

Thieves.

[Illustration: FIG. 2.

Back view of Lock and operating device.

Thumb piece moved upward and bolt thrown back, same as in Fig. 1.]

It is =easily operated, ornamental in appearance=, and does not

interfere with applying weather strips or inside blinds, and is =the

only Side Sash Mortise Lock that= can be used =in connection with

inside screens=, it having been constructed with special reference

to the same. As a rule, =Burglars and Sneak Thieves= have little

difficulty in entering dwellings through windows because of their

insecure fastenings. Hence it is just as important that =each and every

window= should be provided with a =good substantial lock= as that the

front door should be.

=Buy the Timby Burglar Proof, and take no other. The Convenience

and Absolute Security afforded will be ample reward. Full Directions

and Pattern for setting accompany each Lock Sold.=

=The New, Cheap, and Only Superior Substitute for Common Plaster.=

It is hard as marble, and will last as long as the building.

It does away with the warping and shrinking of doors and casings, it

not being necessary, as with common plaster, to saturate the building

with water.

It costs but little more than lime plaster, and its superior qualities

make it immeasurably cheaper.

It saves waiting several weeks or months for the building to dry out. A

room finished one day can be occupied the next.

It does not crack or fall off, even in case of leakages.

It is applied easily by any good mason.

It is the only material with which repairing can be done neatly and “to

stay.”

=The “Barry” Hanger.=

Each wheel on the =“Barry Hanger”= is on an independent axle. All other

hangers have the two wheels on =one axle=. Consequently, when one track

settles more than the other (as they frequently do), the =axle “tips,”=

and carries the door =side‐wise= toward the lowest track, causing an

unpleasant rubbing against the track or casings below. The =“Barry

Hanger”= overcomes this trouble, and a door will run as =easy= and

=true= in the =center=, when there is a variation of one half inch or

more in the height of the tracks, as it would when they are perfectly

level.

Notes and Queries.

(_Continued from page_ vi.)

so as to form a mixture having the consistency of cream, and apply it

immediately with a brush. If this composition be allowed to remain for

a day or two, and be then washed off with soap and water, the marble

will appear as though it were new.

(6) J. M. D. asks: Is there any virtue in the “divining rod,” so

called, as a means of determining the locality of hidden streams of

water? A. None whatever. The bobbing of the stick is due to a muscular

pressure by the holder.

(7) C. W. C. desires (1) a recipe for a stain to imitate mahogany on

white birch wood, that will not raise the grain of the wood. A. A dark

mahogany stain is made as follows: Boil half a pound of madder and 2

ounces of logwood chips in 1 gallon of water, and brush well over the

wood while hot; when dry, go over the whole with pearlash solution,

2 drachms to the quart. 2. Can you give recipe for making the acid

stain? A. In the acid stain you take nitric acid, and dilute with 10

parts of water, and wash the wood with it. 3. Are there any books which

give full directions for imitating the different woods? A. We would

recommend for your purpose Spons’ Workshop Receipts (second series),

which we can send you, postpaid, for $2.00.

(8) A subscriber asks how to make spirit varnish suitable for

varnishing carved wood. A. Take 1 ounce copal and ½ ounce shellac;

powder them well, and put them into a bottle or jar containing 1 quart

alcohol. Place the mixture in a warm place and shake it occasionally

until the gums are completely dissolved; and when strained the varnish

will be ready for use.

(9) J. W. B. desires a recipe for some fire‐extinguishing liquid.

A. One of the best solutions for the extinction of incipient fires

consists of crude calcium chloride 20 parts, salt 5 parts, dissolved in

water 75 parts. Keep at hand, and apply with a hand pump.

(10) G. H. A. says: I have lately made a workshop of an upper room,

and have put in a lathe, boiler, and engine of a total weight of

2,400 pounds, resting upon 3 joists 3 inches by 9 inches by 16 feet 0

inches. Will it strengthen the floor sufficiently to enable it to carry

the increased weight if I bolt three 3 inch by 8 inch joists to the

existing ones? A. You had better use 4 inch by 8 inch joists bolted

with ⅜ inch bolts about 10 inches apart. Take care to provide solid

bearings for your new joists, wedging the ends up with tiles in cement.

(11) W. A. writes: I have noticed in your issue of the SCIENTIFIC

AMERICAN, at various times, the receipt for making a printing machine

called the hektograph. You also gave a recipe for making a black ink

to be used with the same. I have tried both, but I find a great

difficulty in gaining a success. I have tried the process for the ink

in the manner you describe, but I fail to produce any copies. Ink

is prepared with nigrosine. It will not create a bronze. Would you

therefore kindly direct me in the right direction, that is to say, to

get a black ink that can be used by the hektograph? A. The ink you

desire is made by dissolving soluble nigrosine (aniline black) in 5 to

7 parts of water. It should be a saturated solution and rather thick.

For use on the hektograph it is best to use a purple ink. See “The

Copying Pad,” etc., contained in SCIENTIFIC AMERICAN SUPPLEMENT, No.

438.

(12) A. C. R. writes: Can you recommend me a good rubber cement? I wish

to cement leather together, the cement to be waterproof, to resist oil,

and the leather to retain its elasticity after pressing. A. Dissolve

gutta percha in bisulphide of carbon; shave off the edges of the

leather, and pour on the cement; allow to evaporate to dryness. Then

put the two faces together, previously heating thoroughly, and press

until cool.

(13) G. F. asks the best kind of a vessel to make liquid gold in, for

potter’s use. A. Either a glass or a porcelain vessel will answer.

(14) W. J. M. asks how papier mache is made to stand the action of

water. A. Coat with a mixture made by fusing together equal parts

of pitch and gutta percha, to which is added two parts of linseed

oil containing five parts of litharge. Continue the heat until the

ingredients are uniformly commingled, and apply warm.

(15) J. D. & Co. ask a process to prevent the smuts from escaping in

the air from a lampblack house. A. Carry the outlet of your lampblack

chamber to one side and into the top of a vertical shaft, where place a

rose jet of water. Have the water drop vertically in an even spray, so

as to produce a draught down the shaft. The water will gather the waste

lampblack, which can be either utilized or run into the sewer. A vent

at the bottom of the shaft may connect with a chimney or into the open

air. A pump or city water supply will be required.

(16) W. D. G., Jr., asks how large a main pipe will be required to

supply 6 hydrants and 50 dwelling houses, the water to be brought 1

mile with a 70′ head; the hydrants to be used with a 1″ nozzle, and

there being no probability of more than two being required at a time?

A. About a 6″ pipe; a smaller one would not give the desired pressure

for hydrant uses.

(17) S. M. writes: Can you give a formula for a brilliant waterproof

finishing polish to be used on veneer after it is rubbed down with

pumice stone and water? The polish to be applied the same as French

polish. Use linseed oil 1½ pounds, amber 1 pound, litharge 5 ounces,

white lead, pulverized, 5 ounces, minium 5 ounces. Boil the linseed

oil in an untinned copper vessel, and suspend in it the litharge and

minium in a small bag, which must touch the bottom of the vessel.

Continue the boiling until the oil has acquired a deep brown color,

then take out of the bag and put in a clove of garlic; this is to be

repeated 7 or 8 times, the boiling being always continued. Before the

amber is added to the oil it is to be mixed with 2 ounces linseed oil

and melted over a fire that is well kept up. When the mass is fluid, it

is to be boiled and stirred continually for 2 or 3 minutes; afterward

filter the mixture, and preserve it in bottles tightly corked. When

this varnish is used, the wood must be previously well polished and

covered with a thin coat of soot and spirits of turpentine. When the

coat is dry some of the varnish may be applied, which should be equally

distributed on every part with a small, fine sponge. This operation

must be repeated four times, being always careful that each coat will

be well dried first. After the last coat of varnish, the wood must be

dried in an oven and afterward polished.

(18) G. P. writes: We want some plan to prevent the noise or work of

our lodge room (I.O.O.F.) from being heard in the room below; we have a

good floor and carpet, good partitions, walls plastered, etc., but are

willing to go to quite an expense to remedy the present defect on this

score. A. Probably you have no deafening under the floor. In such case

there are only two ways that we can suggest for your trouble: To take

up the floor and put in a plaster deafening between the seams. Next,

to take up the carpet and lay two thicknesses of roof felting or paper

boards (book‐binders’ boards might do, or paper carpet lining). Then

lay battens across the floor, and a new floor on the battens. Do not

nail the battens to the old floor. Then lay the carpet lining and the

carpet on the lining.

(19) W. A.—To clean marble from discoloration: Try 2 parts sodium

carbonate, 1 of pumice stone, and 1 of finely powdered chalk. Mix into

a fine paste with water. Rub this over the marble, and the stains will

be removed; then wash with soap and water.

(20) F. B. asks in regard to papier mache floor covering: 1. Will it

hurt to use printed paper? A. According to the article “A Papier Mache

Floor Covering” we find Manila paper recommended. It is very likely

that newspaper would answer, but it is by no means as strong an article

as the variety spoken of. 2. How thick will that covering be? A. The

thickness depends upon whether more than a single thickness of the

paper is used—probably from one‐sixteenth to one‐eighth of an inch in

thickness. 3. How long will it be before it is ready for use? A. That

depends entirely upon the drying; if artificial heat is applied, we

should think that the whole operation could be carried through and the

covering finished within a week.

(21) C. C. C. asks: Which would be the best test for water works—to

have three streams on one main near each other, or three streams on

different mains scattered over the town? The mains 8 inches, 6 inches,

and 4 inches, works half a mile from town. A. If you are testing in the

interest of contractors, place the trial streams as near the source of

supply as possible, and also near the 8 inch main. A fair test will be

to locate the streams widely apart on one distributing branch.

(22) F. L. asks how to imitate walnut graining. A. Try the following:

The wood, previously thoroughly dried and warmed, is coated once or

twice with a stain composed of 1 ounce extract of walnut peel dissolved

in 6 ounces of soft water by heating it to boiling, and stirring. The

wood, thus treated, when half dry is brushed with a solution of 1 ounce

potassium bichromate in 5 ounces boiling water, and is then allowed to

dry thoroughly, and is to be rubbed and polished as usual.

(23) Z. T. D. asks: How much water per second will flow through a 14

inch pipe, 80 feet long, with 8 feet head? Also, 18 inch and 21 inch

pipes, same conditions? A. The discharge for 14 inch pipe, 18 cubic

feet per second. For 18 inch pipe, 34 cubic feet per second. For 21

inch pipe, 50 cubic feet per second.

[Illustration:

=Office of FITCHBURG GAS CO.=

FITCHBURG, May 17, 1887.

Mr. E. N. GATES.

DEAR SIR: Having now used your system of Hot Water Circulation in my

house from December first to May fifth, it gives me pleasure to say

that it has met the requirements of the extreme cold of the past winter

and the mild weather of the spring months in the most perfect manner,

giving out just the temperature for comfort in all the variations of

temperature outside, and with great economy in fuel. Yours respectfully,

H. F. COGGSHALL, _Treasurer and Manager_.]

=The following Special Advantages over other Methods of Heating=:

1st.—OVER HOT AIR FURNACES.—No Dust! No Burnt Air! No Gas! and

ability to send the heat where it is wanted, without regard to

direction of wind or height of cellar, and using less fuel for amount

of space heated.

2d.—OVER STEAM, HIGH OR LOW PRESSURE.—From the fact the temperature

of water in radiators can be between 70° and 212° or higher, thus

adapting it to all degrees of outside temperature, thereby, taking the

season through, it makes a great saving in fuel in this point alone,

besides the comfort of having a building evenly heated.

3d.—OVER OTHER HOT WATER SYSTEMS.—In all others, the water goes

to Radiators from one common reservoir. Therefore, being next to

impossible to have all rooms heated alike. Different rooms will receive

current of water at different rates of speed. With this system all

rooms can be heated alike, when desired, from the fact that each

current is provided with an independent boiler, and the hot water must

go where the pipe leads, and you have perfect control over every room,

and can be put in at less cost than any other system of hot water

heating to do the same work.

THE FEW ADVANTAGES OF THE COMBINATION SYSTEM AS DEMONSTRATED BY

=THE PERFECTLY COMBINED STEAM AND WARM AIR HEATING APPARATUS.=

[Illustration: Portable: 3 sizes, 28, 32, and 36 inch.]

=1st=.—Two results with but one fire.

=2d=.—All benefit derived from a Steam Heater is radiated in the

Combination, while no sacrifice is made in wasting what you are

compelled to burn before reaching Steam Radiation (212 degrees).

=3d=.—With steam, when fire is banked for the night, radiation

ceases—in the Combination, never!

=4th=.—With steam, the consumption of fuel is the same at 60° as it is

at zero. In the Combination, you burn only what the outside temperature

demands.

=5th=.—The drafts are automatically arranged, requiring no further

attention.

=6th=.—In zero weather all Hot Air Heaters are weak—in the

Combination, steam supplies the power whenever wanted.

With these positive advantages, it is no difficult matter to decide

which to purchase.

A home well heated is a necessity. This comfort can be secured by a

little outlay.
