The Romance of Industry and Invention Part 10

It is the opinion of many naval men of authority that a modern naval battle would only occupy about half the time of a fight in the old Trafalgar days; that half the ships employed would be sunk, and that most of the remainder would be so battered as to be unfit for further service for months to come.

In connection with the Navy Estimates for 1896-7 it was announced in the House of Commons that the following vessels would be constructed: 13 first-cla.s.s battleships, 10 first-cla.s.s cruisers, 16 second-cla.s.s cruisers, 7 third-cla.s.s cruisers, and 48 torpedo-boat destroyers.

SUBMARINE BOATS.

In 1864, during the American civil war, a submarine boat succeeded in sinking the Federal frigate _Housatonic_. This boat, however, was hardly an unqualified success, as, running into the hole made by its torpedo, it went down with the ship; and three crews had previously been lost while carrying out its initial experiments. Since then, many methods of submersion have been tried; but it is only within recent years that naval powers have awakened to the fact that a submersible boat, though by no means so formidable for offensive purposes as its name at first leads one to believe, is a factor which might have to be taken into consideration in the next naval war.

Modern types of these boats are the Holland, Nordenfelt, Tuck, and Goubet. The Holland boat comes to us from over the Atlantic, and is peculiar in its weapon of offence. It is fifty feet long, eight feet in diameter, and is driven by a petroleum engine carrying sufficient fuel for two days' run. The diving is effected by means of two horizontal rudders, one on each side of the stern. This only allows of submersion when the boat is in motion; and the boat cannot be horizontal while submerged. It carries ten-inch gelatine blasting sh.e.l.ls, fired from a pneumatic gun twenty feet long, whose radius of action is two hundred yards under water and one thousand yards above. The use of gelatine is also objectionable, as the confined s.p.a.ce and the vibration of the boat prevent such explosives being carried without some risk of premature explosion. It is for this reason that gun-cotton is adopted in torpedo work, as it will not explode on concussion, and is little affected by change of temperature.

The princ.i.p.al features of the Nordenfelt boat are its method of submersion and its propulsion by steam. The boat is one hundred and twenty-five feet long, twelve feet beam, and displaces two hundred and fifty tons when entirely submerged, one hundred and sixty tons when running on the surface. Her propelling machinery consists of two double cylinder compound engines, with a horse-power of one thousand, and propelling the boat at fifteen knots on the surface. The submersion of the boat is effected by means of two horizontal propellers working in wells at each end. Two conning-towers project about two feet above the deck, of one-inch steel, surmounted by gla.s.s domes, protected with steel bars, for purposes of observation. The boat usually runs on the surface with these towers showing, unless the buoyancy, which is never less than half a ton, is overcome by the horizontal propellers, when the boat becomes partially or totally submerged according to their speed. To ascend to the surface it is only necessary to stop the horizontal propellers, which also stop automatically on reaching a set depth. In the forward tower are the firing keys, machinery and valves necessary for driving or steering the vessel, for controlling the horizontal propellers, and for discharging the Whitehead torpedoes. Four of these are carried, and they are discharged with powder from two tubes in the bows. In the conning-tower are also placed the instruments indicating the depth, level, and course. When the boat is awash, the funnels have to be unshipped and the boat closed up before submersion. The length of time, twenty-five minutes, required for this operation is an objection to this boat, though when submerged it does not get unpleasantly hot.

The temperature after a three hours' submerged run was only ninety degrees Fahrenheit. The crew consists of a captain and eight men.

The Tuck also comes from America. It is of iron, cigar-shaped, thirty feet long and six feet in diameter. It is submerged by means of a horizontal rudder in the stern and a horizontal propeller acting vertically amidships beneath the boat. It is driven by electricity, supplied from storage batteries packed closely in the bows. Compressed air is carried in reservoirs, but a supply is usually obtained when the boat is not far from the surface, by means of an iron pipe twenty feet long, which usually lies on deck, but which can be raised to an upright position by gearing from within. The top then rises above the surface of the water, and by opening a valve in the foot and attaching a pump, fresh air is drawn into the interior. The crew need not exceed three men.

[Ill.u.s.tration: Section of the Goubet Submarine Boat.]

The Goubet cla.s.s are of iron, sixteen feet long, three feet wide, and about six feet deep. The motive power is a Siemens motor driven by storage batteries. Fifty of these boats were purchased by the Russian government. They have no rudder, but a universal joint in the screw shaft permits of the screw being moved through an arc of ninety degrees.

The torpedo is carried outside the boat, secured by a catch worked from inside. On arriving under the enemy, the torpedo is released, and striking the ship's bottom, is held there by spikes. The boat then withdraws, unreeling a connecting wire; and when at a safe distance, fires. The absence of a rudder, however, causes erratic steering, and the spikes with which the torpedo is fitted might fail to stick in steel-bottomed ships.

Submarine boats cannot be driven under water at a speed exceeding six knots. If driven beyond, they are inclined to dive, and in deep water, before the corrective forces against a dive have had time to act, might reach a depth where the pressure would drive in the sides or compress them to a sufficient extent to seriously reduce the displacement. In shallow water, the boat might be driven on to the bottom, and if it be clay, held there, an accident attended with fatal consequences in the case of one boat.

It is also difficult to direct the course of a submarine boat; and it is doubtful whether the advantage of not being seen counteracts the disadvantage of not being able to see. According to Mr Nordenfelt in a lecture on Submarine Boats, 'The mirror of the surface throws a strong light into the boat; you cannot see forward at all, and you cannot see far astern; it is as black as ink outside; you can only see a sort of segment.' This means that you cannot safely advance at a great speed under water. It is impossible to think of a submarine boat as a boat that actually manoeuvres and does its work under water. The boat should run awash, and you can then see where you are. When we consider, then, that a boat totally submerged cannot be driven over six knots, and cannot be properly directed; when we consider the speeds of seventeen and eighteen knots attained by modern battleships, we arrive at the conclusion that boats totally submerged are useless against modern battleships in motion. Running awash, they could be tackled by torpedo catchers and torpedo boats.

CHAPTER VII.

EVOLUTION OF THE CYCLE.

In praise of Cycling--Number of Cycles in Use--Medical Opinions-- Pioneers in the Invention--James Starley--Cycling Tours.

Sir Walter Scott once told a friend that if he did not see the heather once a year he would die. He saw it much oftener than once a year. When the building and planting of Abbotsford had become a pa.s.sion with him, and when the vacation came round in connection with his duties in the Court of Session, he would not stay ten minutes longer in Edinburgh than he could help. Sometimes his carriage would be waiting in Parliament Square to bear him off as swiftly as possible to Abbotsford. John Locke says there is a good vein of poetry buried in the breast of most business men; there is at least in the breast of most men, strong or latent, a longing, a pa.s.sion for freedom, for change. When the buds swell and burst; when the May-blossom breaks forth on the hawthorn, and makes a spring snowstorm in the valley; when the cuckoo is heard, and the lark rains down his drops of melody above the springing clods; when the lambs gambol in the green fields, and the hives are murmurous with their drowsy insect hum--the awakening comes in man, too, for freedom, freshness, change. They are happy who can enjoy such, and be rested and refreshed; for millions are chained to the oar, and know not what they miss, and millions more have not had their eyes or their desires awakened to what they miss. Lowell expresses the feeling:

What man would live coffined with brick and stone, Imprisoned from the healing touch of air, And cramped with selfish landmarks everywhere, When all before him stretches, furrowless and lone, The unmapped prairie none can fence or own?

What man would read and read the self-same faces, And like the marbles which the windmill grinds, Rub smooth for ever with the same smooth minds, This year retracing last year's, every year's, dull traces, When there are woods and unpenfolded s.p.a.ces?

To change and change is life, to move and never rest: Not what we are, but what we hope, is best.

The wild, free woods make no man halt or blind; Cities rob men of eyes and hands and feet.

We want, then, to recover our eyes, and hands, and feet, remembering the story of eyes and no eyes. For this end, few things are better than a day now and then in the open air, in order to bring a man to himself.

The best stimulant in the world is mountain air, and the grandest restorative music the rhythmic beat of the waves along the sh.o.r.e.

The cyclist covers a wonderful stretch of country, going and returning, and comes back refreshed too, though tired, thinking that n.o.body in the universe can have had a better or pleasanter holiday than he has enjoyed. He has whizzed along leafy lanes, with glimpses of running streams to right and left; he has heard the musical monotony of the hill burns as he rested on the bridge; he has awakened sleepy villages, and enjoyed his repasts at country inns. And so the cyclist has a ready power to give himself the requisite and healthful change of scene.

CYCLING.

The pastime of cycling, at first only patronised by athletic youth, has now spread to every cla.s.s of the community. The vast improvement in machines, and the health and exhilaration to be gained by the exercise, have had much to do with its popularity alike with aristocracy and democracy. Like golf, it has come to stay, although many who take cycling up for amus.e.m.e.nt will drop it again as they would do anything else. But there will always remain a strong and increasing contingent, fully aware, by practical experience, of its health and pleasure giving powers, who will place it second to no existing recreation. And so the cyclist gets gleams and glances of beauty from many a nook and corner of the land, where railway, coach, or his unaided pedestrian powers would never carry him. It has widened a twenty-mile radius to a forty-mile radius, and increased man's locomotive powers threefold. Let no one imagine that there is not a considerable amount of exertion and fatigue, and sometimes hardship. But it is of a wholesome kind, when kept within limits, and physically, morally, and socially, the benefits that cycling confers on the men of the present day are almost unbounded.

Truly, we have here a great leveller; as one says: 'It puts the poor man on a level with the rich, enabling him to "sing the song of the open road" as freely as the millionaire, and to widen his knowledge by visiting the regions near to or far from his home, observing how other men live. He could not afford a railway journey and sojourn in these places, and he could not walk through them without tiring sufficiently to destroy in a measure the pleasure which he sought. But he can ride through twenty, thirty, fifty, even seventy miles of country in a day, without serious fatigue, and with no expense save his board and lodging.' This is very well put. Another enthusiast has said: 'If you want to come as near flying as we are likely to get in this generation, learn to ride on a pneumatic bicycle.' 'Sum up,' says another, 'when summer is done, all the glorious days you have had, the splendid bits of scenery which have become a possession for ever, your adventures worth telling, and see how you have been gladdened and enriched.'

An enthusiastic journalist who had been burning the candle at both ends betook himself to the wheel, and found it of so much service to body and mind that he straightway, in the columns of his newspaper, began to advise the whole world to learn the bicycle. He could hardly tell the difference it had made to his feelings and general health, and he knew of no exercise which brought so easily such a universal return in good health, good spirits, and amus.e.m.e.nt. Mr G. Lacy Hillier, of the Badminton volume on Cycling, confirms this. The cyclist seems to enter into the spirit of Emerson's saying as thoroughly as Th.o.r.eau might have done: 'Give me health and a day, and I will make the pomp of empires ridiculous.' Many overdo the exercise, then renounce it, or give it a bad name; others, by over-rapid riding in towns, make themselves public nuisances, and vastly increase the dangers of overcrowded streets. The sensible cyclist rides for health, increase of knowledge, and amus.e.m.e.nt.

Though at one time Mr Ruskin was prepared to spend all his best bad language in abusing the wheel, the world has gone its own way, and the careering mult.i.tudes in Battersea Park and elsewhere, on country and suburban roads, in crowded towns, have been the means of creating new manufactures, which have vastly benefited our home industries. Mr H. J.

Lawson, inventor of the rear-driving safety, lately estimated the annual output of cycles at over a million, and the money spent at over ten millions. But in the absence of statistics this is only guesswork. The periodical called _Invention_ has stated that in 1884 there were 8 bicycle factories, which turned out 6000 machines. In 1895 there were about 400 factories, with an estimated output of 650,000 bicycles. The bicycle tax in France is said to yield not less than 80,000 a year. In the United States, where cycling has become a greater craze than with us, two hundred and fifty thousand cycles at least were purchased in 1894; in 1895 more than four hundred thousand changed hands. When the proposal was made some time ago to impose a tax on cycles, it was calculated that there were at least eight hundred thousand riders in the United Kingdom. Now the number is estimated at over a million. The past few seasons have witnessed quite a 'boom' in cycling and a great increase in the number of riders. Ladies have taken more rapidly to the pastime in America and France than in England. The rubber and then the pneumatic or inflated tyre have wrought a marvellous revolution; the high 'ordinary,' the tricycle, and the heavy 'solid,' and even the 'cushion,' have in most cases been relegated to the home of old iron.

The Pneumatic Tyre Company, with a capital of four millions sterling, when in full swing, turns out twenty-five thousand tyres per week. The profits of this concern in 1896 were at the rate of 432,000 a year.

Coventry, Birmingham, Wolverhampton, London, and other towns, have largely benefited by the cycle trade.

Sir B. W. Richardson has often called attention to the benefit of cycling in the case of dwellers in towns. Dr Turner finds that nothing neutralises better the poison introduced into the blood through faulty digestion than gentle and continued exercise on the wheel. Mr A. J.

Watson, the English amateur one-mile and five-mile champion in 1895, declared that he never suffered from any ill effects, save perhaps during the hard days in winter, when prevented from riding. Dr Andrew Wilson once quoted a budget of correspondence from ladies who had tried the wheel, all of which was in the same direction, provided that overstrain was avoided. Where the heart is weak, cycling should be left alone. The muscles of the legs are developed and the circ.u.mference of the chest increased in the case of healthy riders.

Here are a few hints by a medical man: 'Never ride within half an hour of a meal, either before or after. Wheel the machine up any hill the mounting of which on the wheel causes any real effort. See that the clothing round the stomach, neck, and chest is loose. Have the handle-bar sufficiently raised to prevent stooping. Be as sparing as possible of taking fluids during a long ride. Unless the wind, road, &c., be favourable, never ride more than ten miles an hour, save for very short distances, and never smoke while riding.'

The cycle as we know it did not burst upon the world in all its present completeness, but has been a gradual evolution, the work of many a busy hand and brain, guided by experience. As far back as 1767 we find that Richard Lovell Edgeworth had something of the nature of a velocipede; and about the same date, William Murdoch, inventor of gas for illuminating purposes, had a wooden horse of his own invention upon which he rode to school at c.u.mnock.

The French appear to be ent.i.tled to whatever of credit attaches to the original invention of the hobby-horse, a miserable steed at best, which wore out the toes of a pair of boots at every journey. M. Blanchard, the celebrated aeronaut, and M. Masurier conjointly manufactured the first of these machines in 1779, which was then described as 'a wonder which drove all Paris mad.' The Dandy-horse of 1818, the two wheels on which the rider sat astride, tipping the ground with his feet in order to propel the machine, was laughed out of existence. In 1840, a blacksmith named Kirkpatrick Macmillan, of Courthill, parish of Keir, Dumfriesshire, made a cycle on which he rode to Glasgow, and caused a big sensation on the way. This worthy man died in 1878, aged 68. The notable fact regarding Macmillan's cycle is, that he had adapted cranks and levers to the old dandy or hobby-horse. Gavin Dalziel, of Lesmahagow, Lanarkshire, had a bicycle of his own invention in daily use in 1846. The French are probably justified, moreover, in claiming as their own the development of the crude invention into the present velocipede, for, in 1862, a M. Riviere, a French subject residing in England, deposited in the British Patent Office a minute specification of a bicycle. His description was, however, unaccompanied by any drawing or sketch, and he seems to have taken no further steps in the matter than to register a theory which he never carried into practice.

Subsequently, the bicycle was re-invented by the French and by the Americans almost simultaneously, and indeed, both nations claim priority in introducing it. It came into public notoriety at the French International Exhibition of 1867, from which time the rage for them gradually developed itself, until in 1869 Paris became enthusiastic over velocipedes. Extensive foundries were soon established in Paris for the sole purpose of supplying the ironwork, while some scores of large manufactories taxed their utmost resources to meet the daily increasing demand for these vehicles.

There was a revival of cycling between 1867-69. An ingenious Frenchman, M. Michaux, had some years before fitted pedals and a transverse handle to the front wheel of what came to be irreverently known as the 'bone-shaker.' This embryo bicycle had a considerable vogue, and was introduced to Mr Charles Spencer's gymnasium in London in 1868. Spencer was in Paris in 1868, in company with Mr R. Turner, representative of the Coventry Machinists' Company, and they were each admiring the graceful evolutions of Henri Tascard on his velocipede over the broad asphalt paths of the Luxemburg Gardens. 'Charlie, do you think you could do that?' said Turner. Spencer said he thought he would have a trial, and would take home a machine that very night. He accordingly brought over a machine to London, practised riding stealthily in some of the most out-of-the-way London streets, and soon gained sufficient confidence to appear in public. Mr John Mayall, jun., photographer, Regent Street, witnessed the arrival of one of the first bicycles at Spencer's gymnasium, in Old Street, St Luke's. 'It produced but little impression upon me,' he says, 'and certainly did not strike me as being a new means of locomotion. A slender young man, whom I soon came to know as Mr Turner of Paris, followed the packing-case and superintended its opening. The gymnasium was cleared, Mr Turner took off his coat, grasped the handles of the machine, and, with a short run, to my intense surprise, vaulted on to it, and putting his feet on the treadle made the circuit of the room. We were some half-a-dozen spectators, and I shall never forget our astonishment at the sight of Mr Turner whirling himself round the room--sitting on a bar above a pair of wheels in a line, that ought, as we inadvertently supposed, to fall down as soon as he jumped off the ground.'

It is almost laughable, now, to read how Spencer at first always rode on the pavement, and how politely everybody cleared out of his way. Even Policeman X helped to make a pa.s.sage for him. Some wiseacre, on being quizzed as to the uses of this strange new machine, would reply, 'Why, it is a machine for measuring roads, of course;' and a street arab would shout, 'Oh, crikey, Bill, 'ere's a lark. A swell a ridin' on two wheels. Mind how you fall, sir,' &c. Spencer's speed at first was but five miles an hour. Soon there were many inquiries for this wonderful new aid to locomotion. Spencer and Turner entered heartily into the business. An order for 500 machines was given to the Coventry Machinists' Company in the end of 1868. This was the firm with which Mr James Starley, inventor of the 'Coventry Tricycle,' was connected, and this order helped the start of what has grown to be an enormous and beneficial industry to the town of Coventry.

The account of feats of long-distance riding, of forty and fifty miles a day, got abroad--the feat by Turner, Spencer, and Mayall particularly, in riding to Brighton and back in a day, in February 1869, further popularised cycling. Charles d.i.c.kens and James Payn were amongst those who were bitten by the velocipede 'mania.'

Yet the bone-shaker craze might have died a natural death but for the introduction of the rubber tyre and other improvements. Mr James Starley, of Coventry, through whose inventive genius the tricycle was evolved from the bicycle, was also an improver and pioneer. Starley says of his improvements: 'I regarded the rider as the motive force; and believing it absolutely necessary that he should be so placed that he could exert the greatest amount of power on his pedals, with the least amount of fatigue to himself--believing, also, that the machine of the future must be so made that such essentials as the crank-shaft, pedals, seat, and handles could easily be made adjustable--I decided to change my shape, make my wheels of a good rolling size, place my crank-shaft as near the ground as safety would permit, connect my back wheel with my crank by means of a chain, so that the gear might be adjusted and varied at pleasure, and a short, strong man could ride with a fifty, a sixty, a seventy, or even a higher gear, while a tall, weak man could ride with a lower gear than the short, strong one; to give my saddle a vertical adjustment so that it could be raised or lowered at will; so to place my handles that they could be set forward or backward, raised or lowered, as might be desired; and finally, to make it impossible for the pedalling to interfere with the steering.' In the 'Rover' bicycle he gave an impetus to the early history of the machine, which has been crowned in the pneumatic tyre, the invention of John Boyd Dunlop, born at Dreghorn, Ayrshire, in 1840. Mr Dunlop was engaged as a veterinary surgeon near Belfast, where he built himself an air-wheel from ordinary thin rubber sheets, with rubber valve and plug. Mr C. K. Welch followed with the detachable tyre. The big, ungainly looking wheels were at first laughed at, but when pneumatic tyred machines won race after race, they became the rage. And when the company formed to make the Dunlop tyre sold their interest in the concern, in 1896 it was worth about 3,000,000. The capital originally subscribed was 260,000, and 658,000 had been paid in dividends.

A cycling tour is health-giving and enjoyable when gone about rationally and prudently. It is pleasant to plan, and no less so to carry out, as it is always the unexpected which happens. There are halts by the wayside, conversations with rustics, fine views; and every part of the brain and blood is oxygenated, giving that kind of wholesome intoxication which Th.o.r.eau said he gained by living in the open air.

One's own country is explored as it has never been explored before. Some wheelmen have been credited with seven and eight thousand miles in a single season. Others, more ambitious, have made a track round the globe. Mr Thomas Stevens, starting from San Francisco in April 1884, occupied three years in going round the world. Mr T. Allen and Mr L.

Sachtleben, two American students, as a practical finish to a theoretical education, occupied three years in riding round the world--15,404 miles on the wheel. They climbed Mount Ararat by the way, and interviewed Li Hung Chang, the Chinese viceroy. The wheel ridden by these 'foreign devils' was described by one Chinaman as 'a little mule that you drive by the ears, and kick in the sides to make him go.'

Mr Frank G. Lenz, who started from America in June 1892 to ride round the world, was unfortunately killed by six Kurds, sixty-five miles from Erzeroum, between the villages of Kurtali and Dahar, on May 10, 1894.

There have been many interesting shorter rides. Mr Walter G.o.ddard of Leeds, and Mr James Edmund of Brixton, started from London and rode entirely round Europe on wheels; Mr Hugh Callan rode from Glasgow to the river Jordan; Mr R. L. Jefferson, in 1894, rode from London to Constantinople, between March 10 and May 19. In 1895 the same gentleman rode from London to Moscow, 4281 miles, and had nothing good to say of Russian inns or roads. A lady of sixty has done seventy miles in one day; while an English lady tourist did twelve hundred miles in her various ups and downs between London and Glasgow during one holiday.

The lighter the machine, the more expensive it is. Racing-machines are built as light as twenty pounds in weight. Some of the swiftest road-riders patronise machines of twenty-six or twenty-seven pounds; but for all-round work, one of thirty-three pounds, without lamp or bell, is a good average machine. As to speed, we have had 460 miles in the twenty-four hours on the racing-track, and 377 miles on the road. Huret, a French rider, has done 515 miles between one midnight and another; the Swiss cyclist Lesna has done 28 miles an hour; while Mr Mills and Mr T.

A. Edge, in a ride from Land's End to John o' Groat's on a tandem, beat all previous records, doing the journey in three days four hours and forty-six minutes.

A very sensible American rider, when on tour, starts shortly after breakfast, and with a brief rest for lunch, has his day's work of about fifty miles over by four P.M. Then he changes underclothing--a most important and never-to-be-forgotten matter--has dinner, and an enjoyable ramble over the town or village where he stays over-night. But he is a luxurious dog, and not many will carry such an abundant kit in the triangular bag below the handle bar. Imagine three light outing shirts, three suits, gauze underclothing, a dark flannel bicycle suit, laced tanned gaiters, light-weight rubber coat, comb; clothes, hair, and tooth brushes; soap and towel, writing-pad and pencil, map and matches, and tool bag! Many a cyclist carries a hand camera, and brings home a permanent record of his journeys.

It has been well said that many a boy will start in life with a more vigorous const.i.tution because of the bicycle, and many a man who is growing old too fast by neglect of active exercise will find himself rejuvenated by the same agency. Only let the getting over a certain distance within a certain time not be the main object. And winter riding, when the roads permit, need not be neglected, for nothing is more invigorating than a winter ride. The doctors tell us that as long as one can ride with the mouth shut, the heart is all right. A fillip should be given to the appet.i.te; whenever this is destroyed, and sleeplessness ensues, cycling is being overdone.

Cycling, of course, as we have already said, is not all pleasure or romance. There is a considerable amount of hard work, with head-winds, rain, mud, hills, and misadventures through punctures of the tyre. This last may happen at the most inopportune time; but the cyclist is generally a philosopher, and sets about his repairs with a cool and easy mind.
