As we have on a previous occasion hinted, the principle of ensilage

has, after a manner, been applied for some years to fruit by the

jam-makers. In years of plenty, fruit is reduced to pulp, and can in

this state, if the air is carefully excluded, be made to keep well

until a time of scarcity occurs. Large quantities of apricot pulp finds

its way to this country from France, and realises a good price. In

America, a clever plan of rapid drying and evaporation of the watery

parts of fruit has come into vogue, and this industry gives employment

to many workers. A stove constructed for the purpose costs about

fifteen pounds. It is portable, and is used in many districts far from

towns where there is not a ready market for fresh fruit. As the water

slowly evaporates, the acid and starch in the fruit undergo a chemical

change, and grape-sugar is formed. When placed in water, these dried

fruits once more swell up to their original volume, and are in every

respect like fresh fruit, only that they require, when cooked, but

half the usual quantity of added sugar. All kinds of vegetables can be

preserved by this process.

A correspondent of the _Times_, writing from Iceland, gives some

interesting particulars of the present condition of that island. At

Reykiavik, its chief town, nothing was known of the reported volcanic

disturbances in the interior of the island; but this is hardly to

be wondered at, because a large portion of that area is occupied by

snow-covered mountains and glaciers which the natives never visit, and

which, it may be said, are never explored save by enterprising and

adventurous tourists. Professor Tromholt is in Iceland, pursuing his

researches on the aurora borealis, the frequency and brilliancy of

which, coupled with the exceeding clearness of the atmosphere, give him

every advantage. A large portion of Iceland still remains unexplored;

and its mineral resources, if we except the large quantities of

sulphur which are being worked by an English Company, are but slightly

developed. There is still room for a brisk trade in coal, borax,

copper, &c., which are abundant on the island. Besides these products,

the fisheries of Iceland are most prolific; and although fish and its

belongings form two-thirds of the total exports, it is believed that

they offer a promising field for the further employment of capital.

Among the wonderful engineering projects of the present day must be

mentioned the scheme for making Paris a seaport. This subject lately

engaged the attention of the Rouen Congress of the French Association

for the Advancement of Science, who gave to it two days’ discussion.

One of the chief promoters of the project explained that the proposed

way to carry it out was by transforming the river Seine, by dredging

operations, into a canal ninety-eight feet in width. The amount of soil

to be removed would measure close upon one hundred million cubic yards;

it would consist chiefly of gravel and alluvial earth. The cost of the

entire undertaking is estimated at four millions sterling.

Much attention has of recent years been called to the neglected art

of Irish lace-making. The beauty of design and careful execution of

old specimens of Irish lace contrast very remarkably with modern

productions, which are too often coarse and inartistic. An Exhibition

held last year at the Mansion House, London, and another still more

lately at Cork, have to some extent aroused popular interest in this

most beautiful class of work, and have given some impetus to the

Royal Irish School of Art Needlework. In addition to the labours

of this self-supporting Society, which is doing its best in the

dissemination of good patterns and the employment of trained teachers,

South Kensington has sent one of its emissaries, in the person of Mr

Alan Cole, who has made lace-work his particular study, to lecture

throughout the country. This gentleman is now in Ireland, travelling

about the country wherever his presence is required, and teaching the

application of artistic design to the technical requirements of the

beautiful fabric.

A pretty picture, exhibited some short time ago, represented a little

child looking up inquiringly to the intelligent face of a collie

dog, and was entitled ‘Can’t you Talk?’ Sir John Lubbock has lately

been asking this question of a little black poodle, and has been

endeavouring to teach it to make its wants known by the use of cards

with written characters upon them. Thus, one card bears the word

‘Food,’ another ‘Out;’ and the dog has been taught to bring either the

one or the other to his master, and to distinguish between the meanings

of the two. It seems doubtful whether the dog in this case uses the

faculty of sight or smell; and it would be a source of some interest

and amusement to those possessing an obedient dog, and with time at

their disposal, to carry out the same kind of experiments, using new

cards every time. It is constantly brought home to any observing owner

of a dog that the animal understands a great deal more than he is

generally credited with. In one case, we knew of a Dandy Dinmont who

became so excited when certain things were mentioned in which he was

interested, that French words had to be used in place of English ones

when he was present. Their intelligence is truly marvellous. The wife

of the editor of this _Journal_ possesses a terrier which, while his

mistress is out driving, will remain quietly in the parlour during

her absence, taking no heed of other vehicles that may come to the

front-door in the interval, but instantly recognising by some intuitive

perception the arrival of the carriage or cab that has restored his

mistress. Be it noted that the room in which Tim is confined during

these temporary partings is at the back of the house, apart altogether

from the front-door. This special power of discrimination on the part

of our favourite has always been a marvel to us.

Colonel Stuart Wortley, commenting upon Sir John Lubbock’s experiments,

tells an interesting story concerning a cat which he found during the

Crimean War. The poor creature was pinned to the ground by a bayonet

which had fallen and pierced its foot. The colonel released it; and the

animal attached itself to him, and remained with him to the end of the

war. The first two mornings of their acquaintance the cat was taken to

the doctor’s tent to have his wound dressed. The third morning, the

colonel was on duty; but the cat found its way to the doctor’s all the

same, scratching at the tent for admission, and holding up its paw for

examination.

Some months ago, when every one who had more money than scientific

knowledge was hastening to invest in electric-lighting schemes, we

gave a few words of warning as to the risks involved. That we were not

wrong is evidenced by the collapse of so many of the Companies which

were then issuing rose-coloured prospectuses. We now learn that so

many people have suffered loss in this way, that there is the greatest

difficulty in floating any scheme in which the word ‘Electricity’

occurs; and although inventors are still producing wonderful things,

they cannot get support. There seems, however, to be no doubt whatever

about the genuine success of the Edison Company in New York. The

annual Report of the Company recently issued says that the Pearl

Street Station in that city is working up to its full capacity. It has

nine thousand eight hundred and eleven incandescent lamps in use, and

the machinery has been kept running night and day without cessation

since September 1882. The Company has now two hundred and forty-six

installations at work, with a total of more than sixty thousand lamps.

It may be mentioned as a matter of interest that Edison has had two

hundred and fifteen patents actually granted him, and one hundred more

have been filed. Every small item of his mechanical contrivances forms

the subject of a patent specification.

There is just now such a great demand for handsomely marked leather,

such as that obtained from alligator and boa skin, that the supply

is not nearly equal to said demand. A large proportion of leather

sold as the product of the alligator is really a photograph of the

original article. It is managed in this way. The real skin, with its

curious rectangular spaces separated by grooved markings, is carefully

photographed. From the negative thus obtained a copy is produced in

bichromated gelatine, which has the property, under the action of

light, of affording images in relief. This is easily reproduced in

metal, which serves the purpose of a die. Common cheap leather is

now taken and placed with this die under heavy pressure, when all

the delicate markings of the alligator skin are indelibly impressed

upon it. The finished product can be stained in any way required, but

is more frequently preferred to remain the brown colour left by the

tanning operation. Such is the most recent trade-application of the

fable of the jackdaw and the peacock’s feathers.

An American paper calls attention to a theory of life which, it

asserts, was held by the great Faraday. This theory makes the duration

of life depend upon the time occupied in growth, leaving all questions

of disease or accident which may shorten life out of the question

altogether. Man occupies twenty years in the business of growing. This

number multiplied by five will give the age to which he ought, under

favourable circumstances, to live—namely, one hundred years. A camel,

occupying eight years in growing, ought to live by the same rule forty

years; and so on with other animals. Human life he divided into two

periods—growth and decline, and these were subdivided into infancy,

lasting from birth to the age of twenty; youth, lasting from twenty to

fifty; virility, from fifty to seventy-five; after which comes age.

‘A white-elephant’ has long been the common name of a gift which is

not only useless, but is likely to entail trouble and expense upon

its owner. The animal which has lately found a temporary home at the

Zoological Gardens, London, will not be considered so unwelcome a

guest, for it has drawn thousands of sightseers to the place. It is

reported to have been bought from the king of Burmah on behalf of Mr

Barnum, the American showman. But there seems to be a conflict of

opinion on the point. Those who ought to know say that the exhibited

animal has nothing very remarkable about it, and is certainly unlike

the sacred animals of Burmah. Moreover, it is said that the king of

Burmah would as soon part with his kingdom as with a _real_ white

elephant, which is the emblem of universal sovereignty, the parting

with one of which would forebode the fall of the dynasty.

One of the attractions of the forthcoming International Health

Exhibition will be an Indian village and tea-garden with the plant

actually growing—that is to say, if it can be deluded into growing in

the smoky atmosphere of London. In a tea-house, the beverage will be

served by natives of tea districts, who are to be brought over from

India for the purpose. There will also be exhibited a native pickle

establishment. We venture to assert that if the entire Exhibition is

carried on in this spirit, it is sure to be a success. In past times,

the tea industry would have been represented by a few dozen bottles

of the dried leaf with labels attached, which none would have read.

Our authorities are now learning that if they wish to interest the

multitude in an Exhibition, it must consist of something more than the

dry-bones of the various subjects which it includes.

At a meeting of the Linnæan Society, Mr J. G. Baker lately gave a

very interesting account of a potato new to this country, but common

in Chili, which he believes would thrive well on this side of the

Atlantic. There are known to botanists seven hundred species of

_solanum_. Only six of these produce tubers, and of these six only one

has been as yet cultivated by us, and this is the common potato.[1]

Its true home, according to Mr Baker, is found in those parts of Chili

which are high and dry; but there is another species which flourishes

in moister situations, which he believes might be made to rival its

familiar fellow. When cultivated, it grows most luxuriantly, so much

so, that six hundred tubers have in one year been gathered from two

plants. Some specimens of this same potato were brought to England so

long ago as the year 1826, but they met with little attention, having

been confounded with the more common species. Two other species of

_solanum_, natives of the eastern portion of South America, and found

at Buenos Ayres, &c., are also being cultivated experimentally in

France and in the United States.

A case lately occurred which is deserving of notice, if only as a

caution to those good people who are always ready to assist any

unfortunate who may be seized with a fit. A man acting in this way

the part of good Samaritan to a woman who had fallen in an epileptic

fit, was bitten by her in the hand. In three days the wrist had

swollen to such an extent as to need medical advice, and a few hours

afterwards the poor man died. There may, of course, have been something

exceptional in his state of health, which rendered this human bite more

rapidly fatal than that of a rabid dog; but the lesson to be learned

from the sad story is, that the greatest care should be taken in

dealing with epileptic patients.

common species of potato.

OCCASIONAL NOTES.

TELEGRAPH EXTENSION.

The scheme for the extension of the telegraph system, in anticipation

of the meditated introduction of the sixpence rate, is a most

comprehensive one, and indicates that the Post-office authorities

anticipate a very considerable increase of work. The arrangements cover

the entire kingdom, and the sum to be expended is half a million,

part of the sum having been voted in the official year 1883-84, and

the remainder to be voted in the new estimates. From London, upwards

of eighty new wires are to be erected to the principal towns of the

kingdom, including four additional wires to Liverpool; two each to

Birmingham, Manchester, Leeds, Newcastle, and Newmarket; three to

Glasgow; two to Edinburgh; and one each to a large number of towns,

including, in Scotland, Aberdeen and Dundee. Within London itself, five

new pneumatic tubes are to be provided; about seventy new wires will

be erected; forty existing wires will be provided with instruments to

work ‘duplex’—that is, with the power of transmitting two different

messages by one wire from each end simultaneously; and a very large

number of offices will have simple apparatus substituted by other and

improved instruments. In the city of Liverpool, in addition to the

London wires named, three new wires to Manchester are to be put up;

and one new wire to Belfast, Birmingham, Blackburn, Bristol, Carlisle,

Glasgow, Hull, Leeds, and Newcastle. All those wires and all the new

London wires are to be ‘duplexed,’ and thus each new line practically

counts as two. A number of wires out of Liverpool and the other large

towns will be converted to duplex; and Liverpool is to have eight new

pneumatic tubes for its busier local offices. At Manchester, besides

the London and Liverpool communications already named, there will be

new wires to Birmingham, Chester, Edinburgh, Leeds, Newcastle, Bolton,

Burnley, Derby, Huddersfield, Hull, Isle of Man, and Nottingham,

all duplexed. At Newcastle, an evidence of the curious ramifications

of trade is seen in the fact that a new wire is to be put up between

that town and Cardiff. Bristol obtains new wires to London, Liverpool,

Birmingham, Swansea, and Cardiff; and a share of a new wire for news

purposes with Exeter, Plymouth, &c. Sheffield in the same way has a new

wire to London, and a share in a news circuit with Nottingham, Leeds,

and Bradford. At Birmingham, a number of new local wires, and the

duplexing of others, are provided in addition to the various new trunk

wires already named. In Scotland, a considerable number of new wires

fall to be erected. Edinburgh obtains two of the new London wires, and

wires to Manchester, Kelso, and Musselburgh, with the duplexing of some

important wires, such as those to Kirkcaldy and Perth. Glasgow, with

three London wires added, gets new wires to Dundee, Leeds, Liverpool,

Oban, Kilmarnock, Falkirk, &c.; while a large number of the existing

wires will be duplexed, and in some cases re-arranged to give more

suitable service. A considerable number of new local wires are to be

erected in both cities. In Aberdeen, besides the new London wire, the

principal change will be new wires to Wick and Lerwick—the last a most

important improvement, as Shetland messages will reach London with

two steps, instead of being, as now, repeated at Wick, Inverness, and

Edinburgh or Glasgow.

We observe that the French are about to increase enormously

their telegraphic system, and that the new wires are to be laid

_under_ground. It would be well if, remembering the ever-recurring

havoc wrought upon our overhead wires by gales and snow, we followed

the example of our Gallic neighbours.

AN OIL BREAKWATER AT FOLKESTONE.

A series of experiments has been made at Folkestone, with the result of

very satisfactorily demonstrating the value of the method of spreading

oil over troubled waters which has been devised by Mr John Shields,

of Perth, and which has been already described in this _Journal_.

Many years ago, Mr Shields, observing the effect of a few drops of

oil accidentally spilt on a pond in connection with his works, began

experiments with a view to determine if this property of oil could

not be turned to account on a large scale for the saving of life and

property at sea and on our coasts. He soon arrived at the conclusion

that the problem to be solved was ‘how to get the oil on troubled

waters when it was wanted and where it was wanted.’ By trying various

methods of solving this question, first at Peterhead and then at

Aberdeen, he has worked out the system which, with the co-operation of

the South-eastern Railway Company, has at his expense been placed in

readiness for use during stormy weather off the entrance to the harbour

at Folkestone.

On the 29th January, Mr A. Shields, son of the inventor, and Mr

Gordon, of Dundee, carried out a number of experiments at Folkestone

before a distinguished company. The weather, unfortunately, was not

all that could be desired; it was too moderate, and the wind blowing

from the west did not drive such breakers across the harbour bar as

a strong south-wester would have produced. Nevertheless, the channel

near shore was sufficiently rough to prove the efficiency of Mr

Shields’ arrangements for smoothing it. What was seen by the visitors

may be told in few words. Three large casks were lying on their

sides near the pier-end, and pipes inserted in these were connected

with small force-pumps, each worked by a man. Attention was first

directed to windward towards the unfinished new pier, which juts out

to the south-west. Those who have watched these experiments on former

occasions said they could see the oil rising from a submerged pipe laid

from the old pier-head towards the new pier for a distance of five

hundred feet. The flood-tide, however, was running so strongly that it

was not until the oil had passed the pier that its effects began to be

visible, and these effects were soon more distinctly seen as the two

men stationed at the other barrels began to pump oil into a couple of

pipes, also laid on the sea-bottom, and running across the entrance of

the harbour towards Shakspeare’s Cliff for about one thousand yards. A

fully-manned lifeboat, the _Mayer de Rothschild_, had been rowed out

of the harbour, and was lying off the pier-head, rolling a good deal,

but not getting a splash while in the wide glassy strip of oil-covered

waters that soon stretched away for half a mile or more, though to

seaward of this glistening streak the waves were curling and breaking

into foam. On the harbour-side the effects of the oil were noticeable

far in-shore, and few white caps were to be seen, the film, attenuated

as it must have been, and not more than one hundred feet in width,

acting apparently as an efficient breakwater. When the pumping was

stopped, it was estimated that rather over one hundred gallons of oil

had been used.

The trial, which was as satisfactory as the conditions of weather

permitted, was concluded about one o’clock; yet at four, when the

Boulogne boat came in, broad streaks of comparatively smooth, unbroken

water showed where the oil still lay on the surface. For this permanent

apparatus, lead-pipes of about one and a quarter inch diameter are

used, and at distances of one hundred feet apart there are fixed

upright pipes eighteen inches high, in each of which is a conical

valve, protected from silt by a rose. The oil used was seal-oil, some

kind of so-called fish-oil having been found by experiment to be better

for the purpose than either vegetable or mineral oils.

A second experiment was made at the same place with Mr Gordon’s

invention. This consists of firing shells filled with oil, which, when

the shells burst, spreads itself over the water. Each shell contains

about three-quarters of a gallon of oil. They are fired from mortars,

a charge of eight ounces of pebble powder being used. The shell is

simply an oil-flask, at the bottom of which is a recess for a fuse of

somewhat peculiar construction. It consists of two small chambers. In

these there is a projecting submarine fuse about an inch in length.

The fuse is capped with a composition which renders it absolutely

waterproof, and is so constructed as to secure its ignition with

unfailing certainty. Then the fuse is so timed that it bursts at the

time required, and just as the shell is touching the surface of the

water. The oil from each shell covers a very considerable area of

surface. Somewhere about a dozen of these shells were fired at a range

of from four hundred and fifty to five hundred yards. The effect was

wonderful. The hissing and raging waters were gradually allayed. For

a considerable space the sea was converted into a lake with a gentle

swell, in which a ship or a boat could ride with perfect ease. The

shells, of course, obviate the necessity of pipes, and the smallest

seaport in the kingdom might therefore, with an old mortar and a dozen

or two of gallons of oil, make a temporary harbour of refuge whenever

the necessity arose.

THE CHURCHYARD BY THE SEA.

A MEMORY.

Across the waste of years I see

One spot for ever soft and green,

Which, shrined within my memory,

In evening glow or morning sheen,

Tells of the golden, vanished years,

When smiles came oftener far than tears.

A churchyard by the restless sea,

Where, in deep calm and dreamless sleep,

The Dead lay resting peacefully,

Unheeding the tempestuous deep;

Careless alike of sun and breeze,

Or ebbing of those changeful seas.

And oft when shipwreck and despair

Came to the little sea-beat town,

Pale women, with dishevelled hair,

To the wild shore went hurrying down,

And tenderly dead eyes would close,

And smooth dead limbs for long repose.

Full many a weary, storm-tossed wight,

Year after year, in quiet was laid,

Safe from the blustering storms of night,

In this green spot, and undismayed,

Slept close beside the breakers’ roar,

Whose wrath should mar his rest no more.

And over each low-sleeping head,

Where thymy turf grew green and soft,

The wild bee hummed, and rosy-red

The brier-flower bloomed, and up aloft

The fleecy clouds went drifting by

Like shades, across the summer sky.

And ever as the years go by,

And one by one old memories creep

From out the sweet Past solemnly,

I seem to see, beside the deep,

That little, lonely, silent spot,

With many a childish dream enwrought.

J. H.
