Heroes of the Telegraph Part 6

The principle of this furnace consists in utilising the heat of the products of combustion to warm up the gaseous fuel and air which enters the furnace. This is done by making these products pa.s.s through brickwork chambers which absorb their heat and communicate it to the gas and air currents going to the flame. An extremely high temperature is thus obtained, and the furnace has, in consequence, been largely used in the manufacture of gla.s.s and steel.

Before the introduction of this furnace, attempts had been made to produce cast-steel without the use of a crucible--that is to say, on the 'open hearth' of the furnace. Reaumur was probably the first to show that steel could be made by fusing malleable iron with cast-iron. Heath patented the process in 1845; and a quant.i.ty of cast-steel was actually prepared in this way, on the bed of a reverberatory furnace, by Sudre, in France, during the year 1860. But the furnace was destroyed in the act; and it remained for Siemens, with his regenerative furnace, to realise the object. In 1862 Mr. Charles Atwood, of Tow Law, agreed to erect such a furnace, and give the process a fair trial; but although successful in producing the steel, he was afraid its temper was not satisfactory, and discontinued the experiment. Next year, however, Siemens, who was not to be disheartened, made another attempt with a large furnace erected at the Montlucon Works, in France, where he was a.s.sisted by the late M. le Chatellier, Inspecteur-General des Mines.

Some charges of steel were produced; but here again the roof of the furnace melted down, and the company which had undertaken the trials gave them up. The temperature required for the manufacture of the steel was higher than the melting point of most fire-bricks. Further endeavours also led to disappointments; but in the end the inventor was successful. He erected experimental works at Birmingham, and gradually matured his process until it was so far advanced that it could be trusted to the hands of others. Siemens used a mixture of cast-steel and iron ore to make the steel; but another manufacturer, M. Martin, of Sireuil, in France, developed the older plan of mixing the cast-iron with wrought-iron sc.r.a.p. While Siemens was improving his means at Birmingham, Martin was obtaining satisfactory results with a regenerative furnace of his own design; and at the Paris Exhibition of 1867 samples of good open-hearth steel were shown by both manufacturers.

In England the process is now generally known as the 'Siemens-Martin,'

and on the Continent as the 'Martin-Siemens' process.

The regenerative furnace is the greatest single invention of Charles William Siemens. Owing to the large demand for steel for engineering operations, both at home and abroad, it proved exceedingly remunerative.

Extensive works for the application of the process were erected at Landore, where Siemens prosecuted his experiments on the subject with unfailing ardour, and, among other things, succeeded in making a basic brick for the lining of his furnaces which withstood the intense heat fairly well.

The process in detail consists in freeing the bath of melted pig-iron from excess of carbon by adding broken lumps of pure hemat.i.te or magnet.i.te iron ore. This causes a violent boiling, which is kept up until the metal becomes soft enough, when it is allowed to stand to let the metal clear from the slag which floats in sc.u.m upon the top. The separation of the slag and iron is facilitated by throwing in some lime from time to time. Spiegel, or specular iron, is then added; about 1 per cent. more than in the sc.r.a.p process. From 20 to 24 cwt. of ore are used in a 5-ton charge, and about half the metal is reduced and turned into steel, so that the yield in ingots is from 1 to 2 per cent. more than the weight of pig and spiegel iron in the charge. The consumption of coal is rather larger than in the sc.r.a.p process, and is from 14 to 15 cwt. per ton of steel. The two processes of Siemens and Martin are often combined, both sc.r.a.p and ore being used in the same charge, the latter being valuable as a tempering material.

At present there are several large works engaged in manufacturing the Siemens-Martin steel in England, namely, the Landore, the Parkhead Forge, those of the Steel Company of Scotland, of Messrs. Vickers & Co., Sheffield, and others. These produced no less than 340,000 tons of steel during the year 1881, and two years later the total output had risen to half a million tons. In 1876 the British Admiralty built two iron-clads, the Mercury and Iris, of Siemens-Martin steel, and the experiment proved so satisfactory, that this material only is now used in the Royal dockyards for the construction of hulls and boilers. Moreover, the use of it is gradually extending in the mercantile marine. Contemporaneous with his development of the open-hearth process, William Siemens introduced the rotary furnace for producing wrought-iron direct from the ore without the need of puddling.

The fervent heat of the Siemens furnace led the inventor to devise a novel means of measuring high temperatures, which ill.u.s.trates the value of a broad scientific training to the inventor, and the happy manner in which William Siemens, above all others, turned his varied knowledge to account, and brought the facts and resources of one science to bear upon another. As early as 1860, while engaged in testing the conductor of the Malta to Alexandria telegraph cable, then in course of manufacture, he was struck by the increase of resistance in metallic wires occasioned by a rise of temperature, and the following year he devised a thermometer based on the fact which he exhibited before the British a.s.sociation at Manchester. Mathiessen and others have since enunciated the law according to which this rise of resistance varies with rise of temperature; and Siemens has further perfected his apparatus, and applied it as a pyrometer to the measurement of furnace fires. It forms in reality an electric thermometer, which will indicate the temperature of an inaccessible spot. A coil of platinum or platinum-alloy wire is enclosed in a suitable fire-proof case and put into the furnace of which the temperature is wanted. Connecting wires, properly protected, lend from the coil to a differential voltameter, so that, by means of the current from a battery circulating in the system, the electric resistance of the coil in the furnace can be determined at any moment.

Since this resistance depends on the temperature of the furnace, the temperature call be found from the resistance observed. The instrument formed the subject of the Bakerian lecture for the year 1871.

Siemens's researches on this subject, as published in the JOURNAL OF THE SOCIETY OF TELEGRAPH ENGINEERS (Vol. I., p. 123, and Vol. III., p. 297), included a set of curves graphically representing the relation between temperature and electrical resistance in the case of various metals.

The electric pyrometer, which is perhaps the most elegant and original of all William Siemens's inventions, is also the link which connects his electrical with his metallurgical researches. His invention ran in two great grooves, one based upon the science of heat, the other based upon the science of electricity; and the electric thermometer was, as it were, a delicate cross-coupling which connected both. Siemens might have been two men, if we are to judge by the work he did; and either half of the twin-career he led would of itself suffice to make an eminent reputation.

The success of his metallurgical enterprise no doubt reacted on his telegraphic business. The making and laying of the Malta to Alexandria cable gave rise to researches on the resistance and electrification of insulating materials under pressure, which formed the subject of a paper read before the British a.s.sociation in 1863. The effect of pressure up to 300 atmospheres was observed, and the fact elicited that the inductive capacity of gutta-percha is not affected by increased pressure, whereas that of india-rubber is diminished. The electrical tests employed during the construction of the Malta and Alexandria cable, and the insulation and protection of submarine cables, also formed the subject of a paper which was read before the Inst.i.tution of Civil Engineers in 1862.

It is always interesting to trace the necessity which directly or indirectly was the parent of a particular invention; and in the great importance of an accurate record of the sea-depth in which a cable is being laid, together with the tedious and troublesome character of ordinary sounding by the lead-line, especially when a s.h.i.+p is actually paying out cable, we may find the requirements which led to the invention of the 'bathometer,' an instrument designed to indicate the depth of water over which a vessel is pa.s.sing without submerging a line.

The instrument was based on the ingenious idea that the attractive power of the earth on a body in the s.h.i.+p must depend on the depth of water interposed between it and the sea bottom; being less as the layer of water was thicker, owing to the lighter character of water as compared with the denser land. Siemens endeavoured to render this difference visible by means of mercury contained in a chamber having a bottom extremely sensitive to the pressure of the mercury upon it, and resembling in some respects the vacuous chamber of an aneroid barometer.

Just as the latter instrument indicates the pressure of the atmosphere above it, so the bathometer was intended to show the pull of the earth below it; and experiment proved, we believe, that for every 1,000 fathoms of sea-water below the s.h.i.+p, the total gravity of the mercury was reduced by 1/3200 part. The bathometer, or attraction-meter, was brought out in 1876, and exhibited at the Loan Exhibition in South Kensington. The elastic bottom of the mercury chamber was supported by volute springs which, always having the same tension, caused a portion of the mercury to rise or fall in a spiral tube of gla.s.s, according to the variations of the earth's attraction. The whole was kept at an even temperature, and correction was made for barometric influence. Though of high scientific interest, the apparatus appears to have failed at the time from its very sensitiveness; the waves on the surface of the sea having a greater disturbing action on its readings than the change of depth. Siemens took a great interest in this very original machine, and also devised a form applicable to the measurement of heights. Although he laid the subject aside for some years, he ultimately took it up again, in hopes of producing a practical apparatus which would be of immediate service in the cable expeditions of the s.s. Faraday.

This admirable cable steamer of 5,000 tons register was built for Messrs. Siemens Brothers by Messrs. Mitch.e.l.l & Co., at Newcastle. The designs were mainly inspired by Siemens himself; and after the Hooper, now the Silvertown, she was the second s.h.i.+p expressly built for cable purposes. All the latest improvements that electric science and naval engineering could suggest were in her united. With a length of 360 feet, a width of 52 feet, and a depth of 36 feet in the hold, she was fitted with a rudder at each end, either of which could be locked when desired, and the other brought into play. Two screw propellers, actuated by a pair of compound engines, were the means of driving the vessel, and they were placed at a slight angle to each other, so that when the engines were worked in opposite directions the Faraday could turn completely round in her own length. Moreover, as the s.h.i.+p could steam forwards or backwards with equal ease, it became unnecessary to pa.s.s the cable forward before hauling it in, if a fault were discovered in the part submerged: the motion of the s.h.i.+p had only to be reversed, the stern rudder fixed, and the bow rudder turned, while a small engine was employed to haul the cable back over the stern drum, which had been used a few minutes before to pay it out.

The first expedition of the Faraday was the laying of the Direct United States cable in the winter of 1874 a work which, though interrupted by stormy weather, was resumed and completed in the summer of 1875. She has been engaged in laying several Atlantic cables since, and has been fitted with the electric light, a resource which has proved of the utmost service, not only in facilitating the night operations of paying-out, but in guarding the s.h.i.+p from collision with icebergs in foggy weather off the North American coast.

Mention of the electric light brings us to an important act of the inventor, which, though done on behalf of his brother Werner, was pregnant with great consequences. This was his announcement before a meeting of the Royal Society, held on February 14, 1867, of the discovery of the principle of reinforcing the field magnetism of magneto-electric generators by part or the whole of the current generated in the revolving armature--a principle which has been applied in the dynamo-electric machines, now so much used for producing electric light and effecting the transmission of power to a distance by means of the electric current. By a curious coincidence the same principle was enunciated by Sir Charles Wheatstone at the very same meeting; while a few months previously Mr. S. A. Varley had lodged an application for a British patent, in which the same idea was set forth. The claims of these three inventors to priority in the discovery were, however, antic.i.p.ated by at least one other investigator, Herr Soren Hjorth, believed to be a Dane by birth, and still remembered by a few living electricians, though forgotten by the scientific world at large, until his neglected specification was unexpectedly dug out of the musty archives of the British Patent Office and brought into the light.

The announcement of Siemens and Wheatstone came at an apter time than Hjorth's, and was more conspicuously made. Above all, in the affluent and enterprising hands of the brothers Siemens, it was not suffered to lie sterile, and the Siemens dynamo-electric machine was its offspring.

This dynamo, as is well known, differs from those of Gramme and Paccinotti chiefly in the longitudinal winding of the armature, and it is unnecessary to describe it here. It has been adapted by its inventors to all kinds of electrical work, electrotyping, telegraphy, electric lighting, and the propulsion of vehicles.

The first electric tramway run at Berlin in 1879 was followed by another at Dusseldorf in 1880, and a third at Paris in 1881. With all of these the name of Werner Siemens was chiefly a.s.sociated; but William Siemens had also taken up the matter, and established at his country house of Sherwood, near Tunbridge Wells, an arrangement of dynamos and water-wheel, by which the power of a neighbouring stream was made to light the house, cut chaff turn was.h.i.+ng-machines, and perform other household duties. More recently the construction of the electric railway from Portrush to Bushmills, at the Giant's Causeway, engaged his attention; and this, the first work of its kind in the United Kingdom, and to all appearance the pioneer of many similar lines, was one of his very last undertakings.

In the recent development of electric lighting, William Siemens, whose fame had been steadily growing, was a recognised leader, although he himself made no great discoveries therein. As a public man and a manufacturer of great resources his influence in a.s.sisting the introduction of the light has been immense. The number of Siemens machines and Siemens electric lamps, together with measuring instruments such as the Siemens electro-dynamometer, which has been supplied to different parts of the world by the firm of which he was the head, is very considerable, and probably exceeds that of any other manufacturer, at least in this country.

Employing a staff of skilful a.s.sistants to develop many of his ideas, Dr. Siemens was able to produce a great variety of electrical instruments for measuring and other auxiliary purposes, all of which bear the name of his firm, and have proved exceedingly useful in a practical sense.

Among the most interesting of Siemens's investigations were his experiments on the influence of the electric light in promoting the growth of plants, carried out during the winter of 1880 in the greenhouses of Sherwood. These experiments showed that plants do not require a period of rest, but continue to grow if light and other necessaries are supplied to them. Siemens enhanced the daylight, and, as it were, prolonged it through the night by means of arc lamps, with the result of forcing excellent fruit and flowers to their maturity before the natural time in this climate.

While Siemens was testing the chemical and life-promoting influence of the electric arc light, he was also occupied in trying its temperature and heating power with an 'electric furnace,' consisting of a plumbago crucible having two carbon electrodes entering it in such a manner that the voltaic arc could be produced within it. He succeeded in fusing a variety of refractory metals in a comparatively short time: thus, a pound of broken files was melted in a cold crucible in thirteen minutes, a result which is not surprising when we consider that the temperature of the voltaic arc, as measured by Siemens and Rosetti, is between 2,000 and 3,000 Deg. Centigrade, or about one-third that of the probable temperature of the sun. Sir Humphry Davy was the first to observe the extraordinary fusing power of the voltaic arc, but Siemens first applied it to a practical purpose in his electric furnace.

Always ready to turn his inventive genius in any direction, the introduction of the electric light, which had given an impetus to improvement in the methods of utilising gas, led him to design a regenerative gas lamp, which is now employed on a small scale in this country, either for street lighting or in cla.s.s-rooms and public halls. In this burner, as in the regenerative furnace, the products of combustion are made to warm up the air and gas which go to feed the flame, and the effect is a full and brilliant light with some economy of fuel. The use of coal-gas for heating purposes was another subject which he took up with characteristic earnestness, and he advocated for a time the use of gas stoves and fires in preference to those which burn coal, not only on account of their cleanliness and convenience, but on the score of preventing fogs in great cities, by checking the discharge of smoke into the atmosphere. He designed a regenerative gas and c.o.ke fireplace, in which the ingoing air was warmed by heat conducted from the back part of the grate; and by practical trials in his own office, calculated the economy of the system. The interest in this question, however, died away after the close of the Smoke Abatement Exhibition; and the experiments of Mr. Aiken, of Edinburgh, showed how futile was the hope that gas fires would prevent fogs altogether. They might indeed ameliorate the noxious character of a fog by checking the discharge of soot into the atmosphere; but Mr. Aiken's experiments showed that particles of gas were in themselves capable of condensing the moisture of the air upon them. The great scheme of Siemens for making London a smokeless city, by manufacturing gas at the coal-pit and leading it in pipes from street to street, would not have rendered it altogether a fogless one, though the c.o.ke and gas fires would certainly have reduced the quant.i.ty of soot launched into the air. Siemens's scheme was rejected by a Committee of the House of Lords on the somewhat mistaken ground that if the plan were as profitable as Siemens supposed, it would have been put in practice long ago by private enterprise.

From the problem of heating a room, the mind of Siemens also pa.s.sed to the maintenance of solar fires, and occupied itself with the supply of fuel to the sun. Some physicists have attributed the continuance of solar heat to the contraction of the solar ma.s.s, and others to the impact of cometary matter. Imbued with the idea of regeneration, and seeking in nature for that thrift of power which he, as an inventor, had always aimed at, Siemens suggested a hypothesis on which the sun conserves its heat by a circulation of its fuel in s.p.a.ce. The elements dissociated in the intense heat of the glowing orb rush into the cooler regions of s.p.a.ce, and recombine to stream again towards the sun, where the self-same process is renewed. The hypothesis was a daring one, and evoked a great deal of discussion, to which the author replied with interest, afterwards reprinting the controversy in a volume, ON THE CONSERVATION OF SOLAR ENERGY. Whether true or not--and time will probably decide--the solar hypothesis of Siemens revealed its author in a new light. Hitherto he had been the ingenious inventor, the enterprising man of business, the successful engineer; but now he took a prominent place in the ranks of pure science and speculative philosophy.

The remarkable breadth of his mind and the abundance of his energies were also ill.u.s.trated by the active part he played in public matters connected with the progress of science. His munificent gifts in the cause of education, as much as his achievements in science, had brought him a popular reputation of the best kind; and his public utterances in connection with smoke abatement, the electric light. Electric railways, and other topics of current interest, had rapidly brought him into a foremost place among English scientific men. During the last years of his life, Siemens advanced from the shade of mere professional celebrity into the strong light of public fame.

President of the British a.s.sociation in 1882, and knighted in 1883, Siemens was a member of numerous learned societies both at home and abroad. In 1854 he became a Member of the Inst.i.tution of Civil Engineers; and in 1862 he was elected a Fellow of the Royal Society.

He was twice President of the Society of Telegraph Engineers and the Inst.i.tution of Mechanical Engineers, besides being a Member of Council of the Inst.i.tution of Civil Engineers, and a Vice-President of the Royal Inst.i.tution. The Society of Arts, as we have already seen, was the first to honour him in the country of his adoption, by awarding him a gold medal for his regenerative condenser in 1850; and in 1883 he became its chairman. Many honours were conferred upon him in the course of his career--the Telford prize in 1853, gold medals at the various great Exhibitions, including that of Paris in 1881, and a GRAND PRIX at the earlier Paris Exhibition of 1867 for his regenerative furnace. In 1874 he received the Royal Albert Medal for his researches on heat, and in 1875 the Bessemer medal of the Iron and Steel Inst.i.tute. Moreover, a few days before his death, the Council of the Inst.i.tution of Civil Engineers awarded him the Howard Quinquennial prize for his improvements in the manufacture of iron and steel. At the request of his widow, it took the form of a bronze copy of the 'Mourners,' a piece of statuary by J. G.

Lough, originally exhibited at the Great Exhibition of 1851, in the Crystal Palace. In 1869 the University of Oxford conferred upon him the high distinction of D.C.L. (Doctor of Civil Law); and besides being a member of several foreign societies, he was a Dignitario of the Brazilian Order of the Rose, and Chevalier of the Legion of Honour.

Rich in honours and the appreciation of his contemporaries, in the prime of his working power and influence for good, and at the very climax of his career, Sir William Siemens was called away. The news of his death came with a shock of surprise, for hardly any one knew he had been ill.

He died on the evening of Monday, November 19, 1883, at nine o'clock. A fortnight before, while returning from a managers' meeting of the Royal Inst.i.tution, in company with his friend Sir Frederick Bramwell, he tripped upon the kerbstone of the pavement, after crossing Hamilton Place, Piccadilly, and fell heavily to the ground, with his left arm under him. Though a good deal shaken by the fall, he attended at his office in Queen Anne's Gate, Westminster, the next and for several following days; but the exertion proved too much for him, and almost for the first time in his busy life he was compelled to lay up. On his last visit to the office he was engaged most of the time in dictating to his private secretary a large portion of the address which he intended to deliver as Chairman of the Council of the Society of Arts. This was on Thursday, November 8, and the following Sat.u.r.day he awoke early in the morning with an acute pain about the heart and a sense of coldness in the lower limbs. Hot baths and friction removed the pain, from which he did not suffer much afterwards. A slight congestion of the left lung was also relieved; and Sir William had so far recovered that he could leave his room. On Sat.u.r.day, the 17th, he was to have gone for a change of air to his country seat at Sherwood; but on Wednesday, the 14th, he appears to have caught a chill which affected his lungs, for that night he was seized with a shortness of breath and a difficulty in breathing. Though not actually confined to bed, he never left his room again. On the last day, and within four hours of his death, we are told, his two medical attendants, after consultation, spoke so hopefully of the future, that no one was prepared for the sudden end which was then so near. In the evening, while he was sitting in an arm-chair, very quiet and calm, a change suddenly came over his face, and he died like one who falls asleep. Heart disease of long standing, aggravated by the fall, was the immediate cause; but the opinion has been expressed by one who knew him well, that Siemens 'literally immolated himself on the shrine of labour.' At any rate he did not spare himself, and his intense devotion to his work proved fatal.

Every day was a busy one with Siemens. His secretary was with him in his residence by nine o'clock nearly every morning, except on Sundays, a.s.sisting him in work for one society or another, the correction of proofs, or the dictation of letters giving official or scientific advice, and the preparation of lectures or patent specifications. Later on, he hurried across the Park 'almost at racing speed,' to his offices at Westminster, where the business of the Landore-Siemens Steel Company and the Electrical Works of Messrs. Siemens Brothers and Company was transacted. As chairman of these large undertakings, and princ.i.p.al inventor of the processes and systems carried out by them, he had a hundred things to attend to in connection with them, visitors to see, and inquiries to answer. In the afternoon and evenings he was generally engaged at council meetings of the learned societies, or directory meetings of the companies in which he was interested. He was a man who took little or no leisure, and though he never appeared to over-exert himself, few men could have withstood the strain so long.

Siemens was buried on Monday, November 26, in Kensal Green Cemetery. The interment was preceded by a funeral service held in Westminster Abbey, and attended by representatives of the numerous learned societies of which he had been a conspicuous member, by many leading men in all branches of science, and also by a large body of other friends and admirers, who thus united in doing honour to his memory, and showing their sense of the loss which all cla.s.ses had sustained by his death.

Siemens was above all things a 'labourer.' Unhasting, unresting labour was the rule of his life; and the only relaxation, not to say recreation, which he seems to have allowed himself was a change of task or the calls of sleep. This natural activity was partly due to the spur of his genius, and partly to his energetic spirit. For a man of his temperament science is always holding out new problems to solve and fresh promises of triumph. All he did only revealed more work to be done; and many a scheme lies buried in his grave.

Though Siemens was a man of varied powers, and occasionally gave himself to pure speculation in matters of science, his mind was essentially practical; and it was rather as an engineer than a discoverer that he was great. Inventions are a.s.sociated with his name, not laws or new phenomena. Standing on the borderland between pure and applied science, his sympathies were yet with the latter; and as the outgoing President of the British a.s.sociation at Southport, in 1882, he expressed the opinion that 'in the great workshop of nature there are no lines of demarcation to be drawn between the most exalted speculation and common-place practice.' The truth of this is not to be gain-said, but it is the utterance of an engineer who judges the merit of a thing by its utility. He objected to the pursuit of science apart from its application, and held that the man of science does most for his kind who shows the world how to make use of scientific results. Such a view was natural on the part of Siemens, who was himself a living representative of the type in question; but it was not the view of such a man as Faraday or Newton, whose pure aim was to discover truth, well knowing that it would be turned to use thereafter. In Faraday's eyes the new principle was a higher boon than the appliance which was founded upon it.

Tried by his own standard, however, Siemens was a conspicuous benefactor of his fellow-men; and at the time of his decease he had become our leading authority upon applied science. In electricity he was a pioneer of the new advances, and happily lived to obtain at least a Pisgah view of the great future which evidently lies before that pregnant force.

If we look for the secret of Siemens's remarkable success, we shall a.s.suredly find it in an inventive mind, coupled with a strong commercial instinct, and supported by a physical energy which enabled him to labour long and incessantly. It is told that when a mechanical problem was brought to him for solution, he would suggest six ways of overcoming the difficulty, three of which would be impracticable, the others feasible, and one at least successful. From this we gather that his mind was fertile in expedients. The large works which he established are also a proof that, unlike most inventors, he did not lose his interest in an invention, or forsake it for another before it had been brought into the market. On the contrary, he was never satisfied with an invention until it was put into practical operation.

To the ordinary observer, Siemens did not betray any signs of the untiring energy that possessed him. His countenance was usually serene and tranquil, as that of a thinker rather than a man of action; his demeanour was cool and collected; his words few and well-chosen. In his manner, as well as in his works, there was no useless waste of power.

To the young he was kind and sympathetic, hearing, encouraging, advising; a good master, a firm friend. His very presence had a calm and orderly influence on those about him, which when he presided at a Public meeting insensibly introduced a gracious tone. The diffident took heart before him, and the presumptuous were checked. The virtues which accompanied him into public life did not desert him in private. In losing him, we have lost not only a powerful intellect, but a bright example, and an amiable man.

CHAPTER VI. FLEEMING JENKIN.

The late Fleeming Jenkin, Professor of Engineering in Edinburgh University, was remarkable for the versatility of his talent. Known to the world as the inventor of Telpherage, he was an electrician and cable engineer of the first rank, a lucid lecturer, and a good linguist, a skilful critic, a writer and actor of plays, and a clever sketcher. In popular parlance, Jenkin was a dab at everything.

His father, Captain Charles Jenkin, R.N., was the second son of Mr.

Charles Jenkin, of Stowting Court, himself a naval officer, who had taken part in the actions with De Gra.s.se. Stowting Court, a small estate some six miles north of Hythe, had been in the family since the year 1633, and was held of the Crown by the feudal service of six men and a constable to defend the sea-way at Sandgate. Certain Jenkins had settled in Kent during the reign of Henry VIII., and claimed to have come from Yorks.h.i.+re. They bore the arms of Jenkin ap Phillip of St. Melans, who traced his descent from 'Guaith Voeth,' Lord of Cardigan.

While cruising in the West Indies, carrying specie, or chasing buccaneers and slavers, Charles Jenkin, junior, was introduced to the family of a fellow mids.h.i.+pman, son of Mr. Jackson, Custos Rotulorum of Kingston, Jamaica, and fell in love with Henrietta Camilla, the youngest daughter. Mr. Jackson came of a Yorks.h.i.+re stock, said to be of Scottish origin, and Susan, his wife, was a daughter of [Sir] Colin Campbell, a Greenock merchant, who inherited but never a.s.sumed the baronetcy of Auchinbreck. [According to BURKE'S PEERAGE (1889), the t.i.tle went to another branch.]

Charles Jenkin, senior, died in 1831, leaving his estate so heavily enc.u.mbered, through extravagance and high living, that only the mill-farm was saved for John, the heir, an easy-going, unpractical man, with a turn for abortive devices. His brother Charles married soon afterwards, and with the help of his wife's money bought in most of Stowting Court, which, however, yielded him no income until late in life. Charles was a useful officer and an amiable gentleman; but lacking energy and talent, he never rose above the grade of Commander, and was superseded after forty-five years of service. He is represented as a brave, single-minded, and affectionate sailor, who on one occasion saved several men from suffocation by a burning cargo at the risk of his own life. Henrietta Camilla Jackson, his wife, was a woman of a strong and energetic character. Without beauty of countenance, she possessed the art of pleasing, and in default of genius she was endowed with a variety of gifts. She played the harp, sang, and sketched with native art. At seventeen, on hearing Pasta sing in Paris, she sought out the artist and solicited lessons. Pasta, on hearing her sing, encouraged her, and recommended a teacher. She wrote novels, which, however, failed to make their mark. At forty, on losing her voice, she took to playing the piano, practising eight hours a day; and when she was over sixty she began the study of Hebrew.

The only child of this union was Henry Charles Fleeming Jenkin, generally called Fleeming Jenkin, after Admiral Fleeming, one of his father's patrons. He was born on March 25, 1833, in a building of the Government near Dungeness, his father at that time being on the coast-guard service. His versatility was evidently derived from his mother, who, owing to her husband's frequent absence at sea and his weaker character, had the princ.i.p.al share in the boy's earlier training.

Jenkin was fortunate in having an excellent education. His mother took him to the south of Scotland, where, chiefly at Barjarg, she taught him drawing among other things, and allowed him to ride his pony on the moors. He went to school at Jedburgh, and afterwards to the Edinburgh Academy, where he carried off many prizes. Among his schoolfellows were Clerk Maxwell and Peter Guthrie Tait, the friends of his maturer life.

On the retirement of his father the family removed to Frankfort in 1847, partly from motives of economy and partly for the boy's instruction.

Here Fleeming and his father spent a pleasant time together, sketching old castles, and observing the customs of the peasantry. Fleeming was precocious, and at thirteen had finished a romance of three hundred lines in heroic measure, a Scotch novel, and innumerable poetical fragments, none of which are now extant. He learned German in Frankfort; and on the family migrating to Paris the following year, he studied French and mathematics under a certain M. Deluc. While here, Fleeming witnessed the outbreak of the Revolution of 1848, and heard the first shot. In a letter written to an old schoolfellow while the sound still rang in his ears, and his hand trembled with excitement, he gives a boyish account of the circ.u.mstances. The family were living in the Rue Caumartin, and on the evening of February 23 he and his father were taking a walk along the boulevards, which were illuminated for joy at the resignation of M. Guizot. They pa.s.sed the residence of the Foreign Minister, which was guarded with troops, and further on encountered a band of rioters marching along the street with torches, and singing the Ma.r.s.eillaise. After them came a rabble of men and women of all sorts, rich and poor, some of them armed with sticks and sabres. They turned back with these, the boy delighted with the spectacle, 'I remarked to papa' (he writes),'I would not have missed the scene for anything. I might never see such a splendid one; when PONG went one shot. Every face went pale: R--R--R--R--R went the whole detachment [of troops], and the whole crowd of gentlemen and ladies turned and cut. Such a scene!---ladies, gentlemen, and vagabonds went sprawling in the mud, not shot but tripped up, and those that went down could not rise--they were trampled over.... I ran a short time straight on and did not fall, then turned down a side street, ran fifty yards, and felt tolerably safe; looked for papa; did not see him; so walked on quickly, giving the news as I went.'

Next day, while with his father in the Place de la Concorde, which was filled with troops, the gates of the Tuileries Garden were suddenly flung open, and out galloped a troop of cuira.s.siers, in the midst of whom was an open carriage containing the king and queen, who had abdicated. Then came the sacking of the Tuileries, the people mounting a cannon on the roof, and firing blank cartridges to testify their joy.

'It was a sight to see a palace sacked' (wrote the boy), 'and armed vagabonds firing out of the windows, and throwing s.h.i.+rts, papers, and dresses of all kinds out.... They are not rogues, the French; they are not stealing, burning, or doing much harm.' [MEMOIR OF FLEEMING JENKIN, by R. L. Stevenson.]

The Revolution obliged the Jenkins to leave Paris, and they proceeded to Genoa, where they experienced another, and Mrs. Jenkin, with her son and sister-in-law, had to seek the protection of a British vessel in the harbour, leaving their house stored with the property of their friends, and guarded by the Union Jack and Captain Jenkin.
