PREFACE.

Time was when the foremost aim and ambition of the English housewife

was to gain a full knowledge of her own duties and of the duties of

her servants. In those days, bread was home-baked, butter home-made,

beer home-brewed, gowns home-sewn, to a far greater extent than now.

With the advance of education, there is much reason to fear that the

essentially domestic part of the training of our daughters is being

more and more neglected. Yet what can be more important for the

comfort and welfare of the household than an appreciation of their

needs and an ability to furnish them. Accomplishments, all very good

in their way, must, to the true housewife, be secondary to all that

concerns the health, the feeding, the clothing, the housing of those

under her care.

And what a range of knowledge this implies,--from sanitary

engineering to patching a garment, from bandaging a wound to

keeping the frost out of water pipes. It may safely be said that

the mistress of a family is called upon to exercise an amount of

skill and learning in her daily routine such as is demanded of few

men, and this too without the benefit of any special education or

preparation; for where is the school or college which includes among

its “subjects” the study of such every-day matters as bad drains, or

the gapes in chickens, or the removal of stains from clothes, or the

bandaging of wounds, or the management of a kitchen range? Indeed,

it is worthy of consideration whether our schools of cookery might

not with very great advantage be supplemented by schools of general

household instruction.

Till this suggestion is carried out, the housewife can only refer

to books and papers for information and advice. The editors of the

present volume have been guided by a determination to make it a _book

of reference_ such as no housewife can afford to be without. Much

of the matter is, of course, not altogether new, but it has been

arranged with great care in a systematic manner, and while the use

of obscure scientific terms has been avoided, the teachings of modern

science have been made the basis of those sections in which science

plays a part.

Much of the information herein contained has appeared before in

lectures, pamphlets, and newspapers, foremost among these last

being the _Queen_, _Field_, _Lancet_, _Scientific American_,

_Pharmaceutical Journal_, _Gardener’s Chronicle_, and the _Bazaar_;

but it has lost nothing by repetition, and has this advantage in

being embodied in a substantial volume that it can always be readily

found when wanted, while every one knows the fate of leaflets and

journals. The sources whence information has been drawn have, it is

believed, in every case been acknowledged, and the editors take this

opportunity of again proclaiming their indebtedness to the very large

number of lecturers and writers whose communications have found a

place within these covers.

HOUSEHOLD MANUAL.

_THE DWELLING._

It is both convenient and rational to commence this volume with a

chapter on the conditions which should guide a man in the choice

of his dwelling. Unfortunately there is scarcely any subject upon

which ordinary people display more ignorance, or to which they

pay so little regard. In the majority of instances a dwelling is

chosen mainly with regard to its cost, accommodation, locality, and

appearance. As to its being healthy or otherwise, no _evidence_ is

volunteered by the owner, and none is demanded by the intending

resident. The consequences of this indifference are a vast amount of

preventible sickness and a corresponding loss of money. The following

remarks are intended to educate the house-seeker in the necessary

subjects, being subdivided under distinct headings for facility of

reference.

=Site.=--Of modern scientists who have studied the great health

question, none has more ably treated the essentials of the dwelling

than Dr. Simpson in his lecture for the Manchester and Salford

Sanitary Association. This Association has done wonders in improving

sanitation in the Midlands, and we cannot do better than follow Dr.

Simpson’s teaching.

_Soil._--He insists, first of all, on the great importance of the

soil being _dry_--either dry before artificial means are used to make

it so, or dry from drainage. To this end some elevation above the

surrounding land conduces. A hollow below the general level should,

as a matter of course, be avoided; for to this hollow the water

from all the adjacent higher land will drain, and if the soil be

impervious the water will lodge there. It will thus be damp, and, as

is well known, it will be a colder situation than neighbouring ones

which are a little raised above the general level. Those who live

where they can have gardens will find the advantage of the higher

situation in its being much less subject to spring and early autumn

frosts than the hollow just below. This is due not only to the former

being damper, but to the fact that the heat of the ground on still

nights passes off into space (is “radiated”) more rapidly than from

the higher situation, where there is more movement in the air. The

soil should not be retentive of moisture, as clay is when undrained;

nor should it be damp and moist from the ground water (concerning

which a few words will be said farther on), as is much alluvial

soil, i.e. soil which has been at some former time carried down and

deposited by rivers or floods. On the whole, sand or gravel, if the

site be sufficiently elevated, is probably the best, as it allows

all water to get away rapidly. Then come various rocks, as granite,

limestone, sandstone, and chalk.

Towns often present one specially dangerous, and therefore

specially objectionable soil--that where hollows have been filled

up with refuse of all kinds. This refuse is made up of all kinds

of vegetable, and, more or less, animal matter, often of the most

noxious character, together with cinders, old mortar, and no one

knows what besides. This becomes a foul fermenting mass, which is

often built upon and the houses inhabited before the process of

decomposition is completed, and the noxious gases cease to be given

off. Many outbreaks of disease have been traced most unmistakably

to this criminal act of putting up jerry buildings on pestilential

sites. It is easy for any one to understand how this may be when he

thinks of the way the house acts on the soil it is built upon, or

rather on the moisture and gases contained in the soil. The house is

warmed by the fires and by the people living in it, and the heated

air has a tendency to rise. The pressure on the gases in the soil

is lessened, and they are drawn up into the house, which acts as a

suction pump. This could not happen if the foundation were air-tight;

but this is rarely the case, and too often indeed “cottage property”

is built without any foundation at all. Drs. Parkes and Sanderson

recommended that such soil should not be built upon “for at least

two years,” but it would be well to give it another year. Attention

must also be paid to the “ground water”--the great underground sea

of which we find evidences almost anywhere that we seek for them.

Sometimes it is found even a foot or two only from the surface, in

other places at 15, 20, or 40 ft. This water rises and falls in

some places rapidly, rising after heavy rains, and falling in dry

weather. If it is always near the surface, the place must be damp and

unhealthy; and we should try to find out something about the ground

water before fixing on the site of our house. If possible, do not

live where it is less than 5 or 6 ft. from the surface.

_Trees._--Vegetation assists in rendering the soil healthy. Trees

absorb large quantities of moisture from the soil, and sometimes, as

in the case of the blue gum-tree of Australia, they seem even to do

something more than this. It is said that the common sunflower of

our gardens has a considerable influence in this way. Trees should

not be crowded close to a house, as they keep off much sun, and so

neutralise some of their good effects, but at a reasonable distance

they are beneficial.

_Aspect._--The aspect of a dwelling will necessarily be made to vary

with the climatic conditions of the locality in which it is situated.

In northern latitudes, such as Great Britain occupies, we are rarely

oppressed by sunshine, and need not seek special protection from

it. We should rather be anxious not to be deprived too much of its

genial and life-giving rays. On the other hand, we are often visited

by bleak and bitter winds, and though a free circulation of air is

desirable round a dwelling, there should be some shelter to break

the violence of a cold prevailing wind. In the country, where in

all probability there is no system of drainage for the district,

we should be careful not to place the house so as to receive our

neighbour’s drainage, nor that from our own outbuildings. In a town

the situation should be as open as can be obtained. The wider the

street and the greater the open space at the back the better, and the

back-to-back houses should be avoided altogether. (Simpson.)

As Eassie remarks, in one of the Health Exhibition Handbooks, aspect

and prospect have very much to do with comfort in housebuilding,

since a dwelling may be designed so as to fully command the scenery

while its plan might be very ill-adapted to the prevalent weather,

and the sun’s daily course. A house having a pleasant prospect may

be a decidedly unpleasant dwelling if the rooms have been arranged

without regard to the points of the compass. This will become quite

evident from a careful study of the annexed representation of Prof.

Kerr’s “aspect compass” (Fig. 1), which illustrates most clearly the

direction and character of the prevailing winds of this country, and

the sunny and shady quarters, the imaginary window of the dwelling

occupying the centre of the circle.

Obviously, as Eassie points out, the effects of aspect will not

be the same on the inside and outside of the room. Looking from

a window in the north, the prospect or landscape will be lighted

from behind; to the spectator looking from the south, it will

never be go lighted; looking from the east, the landscape will be

so lighted at sunset; and looking from the west, it will be well

lighted throughout the day. The great thing is to reconcile aspect

and prospect in the choice of a house; but this can seldom be done,

and where it cannot, the question of aspect must be first attended

to, as being of importance to the rooms, and the question of prospect

made secondary. The north is not suitable for a drawing-room, because

the aspect is cold; it is more suitable for a dining-room, as during

the winter the prospect is not seen so much. When the room used for

morning meals looks to the north, a bay window erected to the east

will catch the early sunbeams, and render it pleasant. The northern

aspect is too cold as a rule for bedrooms; but it is quite suitable

for the servants’ day apartments, and admirably adapted to the larder

and dairy. It is especially suited for staircases, as no blinds are

requisite, and the passages can be maintained in a cool state.

[Illustration: 1. Aspect Compass for Great Britain.]

The north-east aspect--next to the north--is best for a dining-room;

it is better for the servants’ offices than even the north; and when

an end window is wanted for a drawing-room, this forms no unpleasant

aspect. Bedrooms which face north-east enjoy the morning sun, and

during the summer range are agreeably cool at night. With regard to

the east, this is also a good aspect for the dining-room, especially

when no distinction is made between the dining-room and the

breakfast-room; and with regard to a sitting-room the more eastward

tendency it has the better. It is not adapted for a drawing-room,

because in the afternoon there is an entire want of sunshine, and on

account of the unhealthy east winds. This point of the compass is

suitable, however, for a library or business-room, because by the

time breakfast is over the sun will fairly have warmed the interior

of the room. It is also a good aspect for the porch, and one side of

a conservatory should always face the east.

The south-east aspect is most suitable for the best rooms of a house,

because it escapes some of the east wind, and part of the scorching

heat and beating rain of the south. It is admirably adapted,

therefore, for a drawing-room or day-room, is the most pleasant

aspect for bedrooms, and is best suited for the nursery or for the

rooms of an invalid. The south-west aspect is the least congenial

of all, because it is so open to a sultry sun and blustering winds.

This aspect should never be chosen for a dining-room; in summer it

is unpleasantly hot for bedrooms; and it is not suitable for a porch

or entrance, on account of the driving rains which prevail during

a portion of the year. The south aspect is not very desirable for

the windows of a dining-room, and is unpleasant for a morning-room,

unless a verandah has been provided. The larder and dairy should

never face the south. The west aspect is not quite agreeable for

a dining-room, on account of the excessive heat prevailing in the

summer afternoons; neither is it desirable for the drawing-room; and

it should never preferably be chosen for bedrooms, although it is

very agreeable for a smoking-room. One side of a conservatory should

always face to the west. The north-west aspect is very good for a

billiard-room, also for a dining-room, if the windows are fitted up

with blinds to shade the sun.

=Construction.= _Foundation._--Bearing in mind what Dr. Simpson

has said as to the house acting as a suction pump, drawing up

moisture and gases, often most noxious, from the soil on which it

is built, it is clear that the foundation ought to be air-tight and

water-tight; for besides the emanations due to the soil, we must

remember that escape from the gas-pipes laid in the street is a very

common occurrence, that sewers are apt to leak, and so the soil in

the neighbourhood of houses may become saturated with filth. Fatal

instances are known where coal gas and other foul vapours have been

drawn, as it were, long distances and poisoned the air of a house

or houses. The only way of guarding against this is to have the

foundations, and some distance outside the foundations, laid in

concrete. There should also be a space between the basement wall

and the surrounding earth. No one, in Eassie’s opinion, would think

of building a dwelling on a patch of ground without first removing

the vegetable mould to some depth below the level of the floor; and

however good the soil, it is very desirable to cover the site with

a layer of concrete to keep out damp and bad exhalations. Rawlinson

even advises a bed of charcoal below the concrete. Simpson insists

that if a cottage floor has to be laid on the bare ground, there

ought at least to be a bed of good concrete below the tiles. Cellars

add to the dryness and healthiness of a house if the walls and floors

are made impervious to air and water, and are properly ventilated.

The walls of the house ought to have a damp-proof course to prevent

the moisture rising in them. To show the importance of this, Simpson

quotes a well-known fact, but one seldom thought of when we look at

the brick walls of our houses. An ordinary well-baked brick, which is

9 in. long, 4½ in. broad, and 2½ in. deep, though apparently solid,

is not really so. It contains innumerable minute spaces through which

air may pass, and into which water may enter; and when it is soaked

in the latter, and all the air is driven out, it will contain nearly

16 oz. (the old pint) of water. If one brick will retain in its pores

so large a quantity, it is easy to see that a large wall may hold

what most people would at first think an incredible amount. As Dr. de

Chaumont says, “A cottage wall only 16 ft. long by 8 ft. high, and

only one brick thick, might hold 46 gallons of water!”

Walls may be made damp not only by water rising in them, but by rain

driving against them, and by water running down from the roof in

consequence of the stoppage of a rain-water pipe. The latter cause

is simple and easily remedied, but the former is far too frequent in

cheaply-built houses. It may be prevented by having cavity walls, as

they are called--that is, a double wall with a space between. There

are several advantages from this. The air space, besides helping to

keep the inner wall dry, is a good non-conductor, and so the house

is all the warmer. There are other methods which may be used in

addition to this, as cementing, plastering, or covering with slates

or boards. There is some difference of opinion as to the advantage

or disadvantage of the walls of a house being porous, as bricks are

when dry; and Prof. de Chaumont seems to think that in our climate

the porosity of the walls is not a point we need trouble ourselves

about maintaining. Still, in Simpson’s opinion, with the ordinary

arrangements of houses as regards supply of air and ventilation,

some porosity of the walls is desirable. Without the freest and

most perfect ventilation, walls absolutely impervious to air, and

therefore to water in a gaseous form, will almost always be more or

less damp on the inside.

[Illustration: 2. Damp Course and Area Wall.]

Another source of dampness in dwellings, as pointed out by Eassie,

is to be found in the practice of building the house walls close

against the earth, without taking the precaution to erect a blind

area-wall between the house wall and the earth excavation. Fig. 2

exhibits both these important improvements--the damp-course and the

area-wall--applied to the same dwelling: _a_ represents the main

wall of the house, and _b_ the area-wall, which is built against

the excavated subsoil, leaving the space _c_ between the two walls;

the thick black line underneath the floor-joist represents the

damp-proof course, which interposes between the subsoil _d_, with

the foundations built upon it, and the main wall of the house. This

damp-proof course usually consists of a layer of pitch or asphalte,

or slates bedded in cement, or specially glazed tiles, known as

Taylor’s or Doulton’s manufactures. By the use of this impervious

course, the upward passage of the ground water is effectually

arrested. The intervening area _c_ it is also well to drain, but

this water should never drain into the soil drain, if avoidable,

and certainly not until it has been thoroughly disconnected. There

should always, also, be a current of air introduced from the outer

air, by way of ventilators put at the top of the blind area _c_, and

an air brick placed above or below the damp-proof course--preferably

above--in order that the space between the ground and the joists or

stone flooring of the basement may be thoroughly ventilated. This

ventilation is shown by the arrows between _e_ and _e_. Such air

currents should always be provided under floors, whether there be

a basement or not, and also always between the joists of the upper

floors, and in the roof, in order to ward off dry-rot and ensure a

constant circulation of air. (Eassie.)

_Roof._--The first detail to be decided on is the “pitch” or slope to

be given to the roof, and this will depend both on the nature of the

covering material and the character of the climate. In the tropics,

where rain falls in torrents, a flat pitch helps to counteract the

rush of water; in colder regions the pitch must be such as to readily

admit of snow sliding off as it accumulates, to prevent injury

to the framework by the increased weight. The pitches ordinarily

observed, stated in “height of roof in parts of the span,” are as

follows:--Lead, 1/40; galvanized iron or zinc, ⅕; slates, ¼; stone,

slate, and plain tiles, 2/7; pantiles, 2/9; thatch, felt, and wooden

shingles, ⅓ to ½.

In country districts the roofs of cottages and outbuildings

are frequently covered with thatch. This consists of layers of

straw--wheaten lasts twice as long as oaten--about 15 in. in

thickness, tied down to laths with withes of straw or with string.

Thatch is an excellent non-conductor of heat, and consequently

buildings thus roofed are both cooler in summer and warmer in winter

than others, and no better roof covering for a dairy can be found.

Thatch is, however, highly combustible, and as it harbours vermin and

is soon damaged, it is not really an economical material, though the

first cost is small. A load of straw will do 1½ “squares” of roofing,

or 150 superficial feet. First class thatching is an art not readily

acquired. While really good thatching will stand for 20 years,

average work will not endure 10.

A convenient roofing material when wood is cheap and abundant

consists of a kind of “wooden slates,” split pieces of wood measuring

about 9 in. long, 5 in. wide, and 1 in. thick at one end but tapering

to a sharp edge at the other. Shingles, or wooden slates, are made

from hard wood, either of oak, larch, or cedar, or any material that

will split easily. Their dimensions are usually 6 in. wide by 12 or

18 in. long, and about ¼ in. thick.

Roofing felt is a substance composed largely of hair saturated with

an asphalte composition, and should be chosen more for closeness of

texture than excessive thickness. It is sold in rolls 2 ft. 8 in.

wide and 25 yd. long, thus containing 200 ft. super in a roll. Before

the felt is laid on the boards (¾ in. close boarding), a coating

composed of 5 lb. ground whiting and 1 gal. coal tar, boiled to expel

the water, is applied, while still slightly warm, on the boards

themselves; the felt is then laid on, taking care to stretch it

smooth and tight, and the outside edge is nailed closely with ⅞ in.

zinc or tinned tacks. The most common application to a felt roof is

simple coal tar brushed on hot and sprinkled with sharp sand. It is

not well adapted to dwellings.

Dachpappe is a kind of asphalte pasteboard much employed in Denmark;

it is laid on close boarding at a very low pitch, and forms a light,

durable covering, having the non-conducting properties of thatch.

It is sold in rolls 2 ft. 9 in. wide and 25 ft. long, having a

superficial content of 7½ sq. yd., at the rate of 1_d._ per sq. ft.

When laid, it requires dressing with an asphalte composition called

“Erichsen’s mastic,” sold at 9_s._ 9_d._ per cwt., 1 cwt. of the

varnish sufficing to cover a surface of 65 sq. yd.

Willesden paper is another extremely light, durable, and waterproof

roofing material, which differs essentially from the 2 preceding

substances in needing to be fixed to rafters or scantling, and

requiring no boarding on the roof. It is a kind of cardboard treated

with cuprammonium solution, and has become a recognized commercial

article. It is made in rolls of continuous length, 54 in. wide,

consequently, when fixing the full width of the card (to avoid

cutting to waste), the rafters should be spaced out 2 ft. 1 in. apart

from centre to centre, so that the edge of one sheet of card laid

vertically from eaves to ridge will overlap the edge of the adjoining

sheet 4 in. on every alternate rafter.

By far the most important and generally used roofing material in

this country is slate. Its splitting or fissile property makes it

eminently useful as a roofing material, as, notwithstanding the

fact that it is one of the hardest and densest of rocks, it can be

obtained in such thin sheets that the weight of a superficial foot is

very small indeed, and consequently, when used for covering roofs, a

heavy supporting framework is not required. Slate absorbs a scarcely

perceptible quantity of water, and it is very hard and close-grained

and smooth on the surface; it can be laid safely at as low a pitch as

22½°. In consequence of this, the general introduction of slate as a

roofing material has had a prejudicial effect upon the architectural

character of buildings. The bold, high-pitched, lichen-covered roofs

of the middle ages--which, with their warm tints, form so picturesque

a feature of many an old-fashioned English country town--have given

place to the flat, dull, slated roofs. The best roofing slate

is obtained from North Wales, chiefly in the neighbourhood of

Llanberis. Non-absorption of water is, of course, the most valuable

characteristic; an easy test of this can be applied by carefully

weighing one or two specimens when dry, and then steeping them in

water for a few hours and weighing them again, when the difference in

weight will of course represent the quantity of water absorbed. The

light-blue coloured slates are generally superior to the blue-black

varieties. (J. Slater.)

Some architects bed the roofing slates in hydraulic cement, instead

of having them nailed on dry in the usual way, which leaves them

subject to be rattled by the wind, and to be broken by any accidental

pressure. The cement soon sets and hardens, so that the roof becomes

like a solid wall. The extra cost is 10 or 15 per cent., and it is

good economy, considering only its permanency, and the saving in

repairs; but, besides this, it affords great safety against fire, for

slate laid in the usual way will not protect the wood underneath from

the heat of a fire at a short distance.

Tiles are much used in some districts, and are often made of a

pleasant tint; but a great objection to all tiles is their porosity,

which causes them to absorb much water, rotting the woodwork and

adding to their own already considerable weight.

Metallic roofing embraces sheet copper, sheet zinc, sheet lead,

“galvanised” iron, and thin plates of “rustless” (Bower-Barff) iron.

These materials are only used on flat or nearly flat spaces.

_Floors._--Tiles or flags are most frequently used for the floors

of kitchens, sculleries, and lobbies. They serve this purpose very

well, as they are easily washed and not likely to be injured, but

the joints should be made impervious to moisture. In some parts of

the country, concrete is used; this answers very well for the same

purpose, but it is not good for bedrooms, as it is so cold to the

feet. Wood makes the most comfortable floor for sitting or bed rooms,

and the best is hard wood capable of bearing a polish. From its

convenience and cheapness, common deal is used very generally, and

too often in a damp and unsound state, so that the boards shrink and

wide gaps are left between. This allows all the foul air from any

space--as a cellar or a cavity between the floor and the soil--to

ascend into the room. The boards ought to be as close together as

possible, and any spaces left between them should be packed tightly

with oakum. If this is done, the floors may be stained and varnished,

when they can be swept and rubbed clean, and do not require such

frequent washing as the ordinary unvarnished floors. This is an

important gain, for there is no doubt that emanations rising with

the damp from newly-washed floors are often most injurious. If a

varnished floor is washed, it dries almost at once. Spaces must be

left under the floors, on the ground level, if they are of wood, or

they will soon decay; and they ought to be well ventilated. Ceilings,

leaving a space between them and the boards of the room above, have

come into use, most likely to deaden sound. They often fail of this,

while affording fine playgrounds to mice, and even rats. Well-laid

boards, of sufficient thickness, and plugged with oakum, would, as

regards health, be preferable. (Dr. Simpson.)

_General Arrangement._--The chief points to be insisted on in a

dwelling are enumerated by Simpson as follows:--Every room should

obtain light and air from the outside, and there should be free

communication from front to back, so that a current of air may

pass through the house. What are called back-to-back houses are

very objectionable, and to be carefully avoided. If there is a

closet attached to the house, it should, as a matter of course,

be ventilated by a window opening both above and below, and, if

possible, should be built in a projecting wing or tower, and have

double doors, with space between them for a window on each side, so

as to have cross ventilation. When there is no closet in the house,

it should be completely detached from it, and all piggeries, middens,

&c., should be as far removed as possible. Speaking even of large

houses, Eassie remarks that they are often very faultily planned in

respect to the position in that portion of the interior which is

usually appropriated to sinks and water-closets. In the basement, for

instance, closets are often placed almost in the middle of the house,

and the same mistake is committed on the floors above, a worse error

by far; because then the closet would be placed on the landing of the

stair opposite the best ground-floor, and chamber-floor rooms--the

only ventilation from the closet-rooms being into the staircase, and

consequently into the house.

Precaution against Snakes entering Dwellings.--There is no regular

system adopted to prevent snakes entering dwelling-houses in Ceylon,

as it is of rare occurrence to find any but rat snakes in European

dwellings, and these are not venomous; but it is usual to clear away

a portion of space about each bungalow and put on sharp gravel, and

also to have coir matting laid down upon the verandahs, as snakes

dislike crossing over rough surfaces such as gravel and coir. Trees

should be at such a distance from the house (or bungalow) as to

prevent the possibility of snakes dropping from the branches on to

the roof.

Reducing Echoes and Reverberations.--The report of a committee of a

Würtemberg association of architects upon the deadening of ceilings,

walls, &c., to sound, gave rise to considerable debate, after which

the following conclusions were reached. The propagation of sound

through the ceiling may be most effectually prevented by insulating

the floor from the beams by means of some porous light substance,

as a layer of felt, a filling of sand, or of stone coal dust, the

latter being particularly effective. It is difficult to prevent the

propagation of sound through thin partitions, but double unconnected

walls filled in with some porous material have been found to answer

the purpose best. Covering the walls and doors with hangings, as of

jute, is also quite serviceable.

To those who carry on any operations requiring much hammering or

pounding, a simple means of deadening the noise of their work is a

great relief. Several methods have been suggested, but the best are

probably these:

1. Rubber cushions under the legs of the work-bench. _Chambers’s

Journal_ describes a factory where the hammering of fifty

coppersmiths was scarcely audible in the room below, their benches

having under each leg a rubber cushion.

2. Kegs of sand or sawdust applied in the same way. A few inches

of sand or sawdust is first poured into each keg; on this is laid

a board or block upon which the leg rests, and round the leg and

block is poured fine dry sand or sawdust. Not only all noise, but

all vibration and shock, is prevented; and an ordinary anvil, so

mounted, may be used in a dwelling-house without annoying the

inhabitants. To amateurs, whose workshops are almost always located

in dwelling-houses, this device affords a cheap and simple relief

from a very great annoyance.

Echoes are broken up by stretching wires across the room at about

4-5 ft. above the heads of the audience. Often there is strong echo

from the windows, which is lessened by the use of curtains, but with

some sacrifice of light. Very thin semi-transparent blinds would

check echo a good deal, but architects should not have large windows

in the same plane; large unbroken surfaces of any kind are very apt

to reflect echoes, yet we constantly see rooms intended for public

meetings so built as to be spoiled by the confusing echoes.

Waterproofing Walls.--In many badly constructed houses with thin

walls there is a tendency for damp to make its way into the interior.

Several remedies for this inconvenience have been published at

various times. The following procedure is described by a German paper

as a reliable means of drying damp walls. The wall, or that part

of it which is damp, is freed from its plaster until the bricks or

stones are laid bare, next further cleaned off with a stiff broom,

and then covered with the mass prepared as below, and dry river-sand

thrown on as a covering. Heat 1 cwt. of tar to boiling-point in a

pot, best in the open air; keep boiling gently, and mix gradually

3½ lb. of lard with it. After some more stirring, 8 lb. of fine

brickdust are successively put into the liquid, and moved about until

thoroughly disintegrated, which has been effected when, on dipping

in and withdrawing a stick, no lumps adhere to it. The fire under

the pot is then reduced, merely keeping the mass hot, which in that

state is applied to the wall. This part of the work, as well as the

throwing on of the river-sand against the tarred surface, must be

done with the trowel quickly and with sufficient force. It must be

continued until the whole wall is covered both with the tar mixture

and the sand. The tar must not be allowed to get cold, nor must the

smallest possible spot be left uncovered, as otherwise damp would

show itself again in such places, and where no sand has been thrown

the following coat of plaster would not stick. When the tar covering

has become cold and hard, the usual or gypsum coating may be applied.

It is asserted that, if this covering has been properly dried, even

in underground rooms, not a sign of dampness will be perceived. About

300 sq. ft. may be covered with the quantities above stated.

An excellent asphalte or mortar for waterproofing damp walls or other

surfaces is the following patented composition:--Coal tar is the

basis, to which clay, asphalte, rosin, litharge, and sand are added.

It is applied cold, and is extremely tenacious and weather-resisting.

The area to be covered is first dried and cleaned, then primed with

hot roofing varnish--chiefly tar. The mortar is then laid on cold

with trowels, leaving a coat ⅜ in. thick. A large area is then

coated with varnish and sprinkled over with rough sand. To frost or

rain this mortar is impervious. The cost is 5_d._ per sq. ft., and

for large quantities 4_d._ In the case of stone walls the following

ingredients, melted and mixed together, and applied hot to the

surface of stone, will prevent all damp from entering, and vegetable

substance from growing upon it. 1½ lb. rosin, 1 lb. Russian tallow, 1

qt. linseed-oil. This simple remedy has been proved upon a piece of

very porous stone made into the form of a basin; two coats of this

liquid, on being applied, caused it to hold water as well as any

earthenware vessel.

For brickwork, the _Builder_ gives the following remedy:--¾ lb. of

mottled soap to 1 gal. of water. This composition to be laid over

the brickwork steadily and carefully with a large flat brush, so as

not to form a froth or lather on the surface. The wash to remain 24

hours to become dry. Mix ½ lb. of alum with 4 gal. of water; leave it

to stand for 24 hours, and then apply it in the same manner over the

coating of soap. Let this be done in dry weather.

Another authority says, coat with venetian red and coal tar, used

hot. This makes a rich brown colour. It can be thinned with boiled

oil.

A Devonshire man recommends “slap-dashing,” as is often done in

Devon. The walls are, outside, first coated with hair-plaster by the

mason, and then he takes clean gravel, such as is found at the mouth

of many Devonshire rivers, and throws--or, as it is called locally,

“scats” it--with a wooden trowel, with considerable force, so as to

bed itself into the soft plaster. You can limewash or colour to your

liking, and your walls will not get damp through.

Perhaps no application is cheaper or more efficacious than the

following. Soft paraffin wax is dissolved in benzoline spirit in the

proportion of about one part of the former to four or five parts of

the latter by weight. Into a tin or metallic keg, place 1 gal. of

benzoline spirit, then mix 1½ lb. or 2 lb. wax, and when well hot

pour into the spirit. Apply the solution to the walls whilst warm

with a whitewash brush. To prevent the solution from chilling, it

is best to place the tin in a pail of warm water, but on no account

should the spirit be brought into the house, or near to a light, or a

serious accident might occur. The waterproofed part will be scarcely

distinguishable from the rest of the wall; but if water is thrown

against it, it will run off like it does off a duck’s back. Whilst

it is being applied the smell is very disagreeable, but it all goes

off in a few hours. On a north wall it will retain its effect for

many years, but when exposed much to the sun, it may want renewing

occasionally. Hard paraffin wax is not so good for the purpose, as

the solution requires to be kept much hotter.

Curing a Damp Cellar.--A correspondent inquired of the editor of

the _American Architect_ what remedy he would suggest for curing a

damp cellar. The difficulty to be overcome, presents the questioner,

in a new house is the wet cellar. Conditions present, concrete not

strong enough to resist the hydraulic pressure through a clay soil.

No footings under wall (which are of brick.) No cement on outside

of wall. The water evidently, however, forces its way through the

concrete bottom.

(_a_) Will reconcreting (using Portland cement) resist the pressure

of water and keep it out?

(_b_) If not, will a layer of pure bitumen damp-course between the

old and new concrete do the work?

(_c_) Will it do any good to carefully cement the walls on the inside

with rich Portland cement, say 3 ft. high, to exclude damp caused by

capillary attraction through the brick wall?

In reply to the above queries the editor gave the following hints,

which are equally applicable to builders of new houses as to those

occupying old houses with damp cellars:

It is doubtful whether even Portland cement concrete would keep back

water under sufficient pressure to force it through concrete made

of the ordinary cement. The best material would be rock asphalte,

either Seyssel, Neufebatel, Val de Travers, Yorwohle, or Limmer, any

of which, melted, either with or without the addition of gravel,

according to the character of the asphalte, and spread hot to a depth

of ¾ in. over the floor, will make it perfectly water-tight. The

asphalte coating should be carried without any break 18 or 20 in. up

on the walls and piers, to prevent water from getting over the edge;

and if the hydrostatic pressure of the water should be sufficient to

force the asphalte up, it must be weighted with a pavement of brick

or concrete. This is not likely to be necessary, however, unless the

cellar is actually below the line of standing water around it.

This, although an excellent method of curing the trouble, the

asphalte cutting off ground air from the house, as well as water,

will be expensive, the cost of the asphalte coating being from 20 to

22 cents (10-11_d._) a sq. ft.; and perhaps it may not be necessary

to go to so much trouble. It is very unusual to find water making its

way through ordinary good concrete, unless high tides or inundations

surround the whole cellar with water. If the source of the water

seems to be simply the soakage of rain into the loose material filled

in about the outside of the new wall, we should advise attacking

this point first, and sodding or concreting with coal-tar concrete,

a space 3 or 4 ft. wide around the building. This, if the grade is

first made to slope sharply away from the house, will throw the rain

which drips from the eaves, or runs down the walls, out upon the

firm ground, and in the course of two or three seasons the filling

will generally have compacted itself to a consistency as hard as or

harder than the surrounding soil, so that the tendency of water to

accumulate just outside the walls will disappear; while the concrete,

as it hardens with age, will present more and more resistance to

percolation from below.

For keeping the dampness absorbed by the walls from affecting the air

of the house, a Portland cement coating may be perhaps the best means

now available. It would have been much better, when the walls were

first built, to brush the outside of them with melted coal tar; but

that is probably impracticable now. If the earth stands against the

walls, however, the cement coating should cover the whole inside of

the wall. The situation of the building may perhaps admit of draining

away the water which accumulates about it, by means of stone drains

or lines of drain tile, laid up to the cellar walls, at a point below

the basement floor, and carried to a convenient outfall. This would

be the most desirable of all methods for drying the cellar, and

should be first tried.

Construction for Earthquake Countries.--The conditions will vary

somewhat according to the nature of the climate.

R. H. Brunton, who was for many years resident lighthouse engineer

in Japan, follows the principles enunciated by Mallet and Prof.

Palmieri, giving the buildings weight and great inertia, coupled with

a good bond between their various parts. Prof. Palmieri states that,

although solidity and strength in a building do not afford perfect

protection, still, so long as fracture does not occur, overthrow is

impossible. Dyer states that in his opinion, for dwelling-houses

in Japan, the modifications of external design required, as

compared with those in Britain, arise not so much on account of the

earthquakes as from the heats of summer, the colds of winter, and

the typhoons of autumn. Iron roofs are good from a merely structural

point of view; but in summer it would be impossible to live in the

houses provided with them. If a non-conducting material of the same

strength and durability as iron could be found, it might be used.

“If the houses are so designed as to be comfortable as regards

temperature, and the construction made in good brick, or equally

strong stone and mortar, so that the walls are of nearly a uniform

strength; if no unnecessary top weights are used, and if the various

parts do not vibrate with different periods, they will withstand all

ordinary earthquakes, and other precautions will be unnecessary, as

these generally produce results more serious than those due to the

earthquakes.”
