'I then applied for a patent, but before preparing my provisional specification (dated October 17, 1855), I searched for other patents to ascertain whether anything of the sort had been done before. I then found yourpatent for puddling with the steam-rabble, and also Martin's patent for the use of steam in gutters while molten iron was being conveyed from the blast-furnace to a finery, there to be refined in the ordinary way prior to puddling.'
Several leading men in the iron trade took licenses for the new manufacture, which brought Bessemer £27,000 within thirty days of the time of reading his paper. These licenses he afterwards bought back for £31,000, giving fresh ones in their stead. Some of the early experiments failed, and it was feared the new method would prove impracticable. These experiments failed because of the presence of phosphorus in the iron. But Bessemer worked steadily in order to remove the difficulties which had arisen, and a chemical laboratory was added to his establishment, with a professor of chemistry attached. Success awaited him. The new method of steel-making spread into France and Sweden, and in 1879 the works for making Bessemer steel were eighty-four in number, and represented a capital of more than three millions. His process for the manufacture of steel raised the annual production of steel in England from 50,000 tons by the older processes to as many as 2,000,000 tons in some years. It was next used for boiler-plates; shipbuilding with Bessemer steel was begun in 1862, and now it is employed for most of the purposes for which malleable iron was formerly used. The production of Europe and America in 1892 was over 10,000,000 tons, of a probable value of £84,000,000, sufficient, as has been remarked, to make a solid steel wall round London 40 feet high, and 5 feet thick. It would take, according to the inventor, two or three years' production of all the gold-mines in the world to pay in gold for the output of Bessemer steel for one year. The price of steel previous to Huntsman's process was about £10,000 per ton; after him,from £50 to £100. Now Bessemer leaves it at £5 to £6 per ton. And a process which occupied ten days can be accomplished within half an hour.

In his sketch of the 'Bessemer Steel Industry, Past and Present' (1894), Sir Henry Bessemer says: 'It is this new material, so much stronger and tougher than common iron, that now builds our ships of war and our mercantile marine. Steel forms their boilers, their propeller shafts, their hulls, their masts and spars, their standing rigging, their cable chains and anchors, and also their guns and armour-plating. This new material has covered with a network of steel rails the surface of every country in Europe, and in America alone there are no less than 175,000 miles of Bessemer steel rails.' These steel rails last six times longer than if laid of iron.
Bessemer was knighted in 1879, and has received many gold medals from scientific institutions. In addition he has, to use his own words, received in the form of royalties 1,057,748 of the beautiful little gold medals (sovereigns) issued by her Majesty's Mint. The method chosen by the Americans to perpetuate his name has been the founding of the growing centre of industry called Bessemer in Indiana, while Bessemer, in Pennsylvania, is the seat of the great Edgar Thompson steel-works. Thus the man who was at first neglected by government has become wealthy beyond the dreams of avarice, and his name is immortal in the annals of our manufacturing industry.
Another pioneer in the manufacture of steel and iron wasCharles William Siemens, the seventh child of a German landowner, who was born at Lenthe, nearHanover, 4th April 1823. He showed an affectionate and sensitive disposition while very young, and a strong faculty of observation. He received a good plain education at Lübeck, and in deference to his brother Werner he agreed to become an engineer, and accordingly was sent to an industrial school at Magdeburg in 1838, where he also learned languages, including English; mathematics he learned from his interested brother. He left Magdeburg in 1841 in order to increase his scientific knowledge at Göttingen, and there he studied chemistry and physics, with the view of becoming an engineer. Werner, his elder brother, was still his good genius, and after the death of their parents counselled and encouraged him, and looked upon him as a probable future colleague. They corresponded with one another, not only about family affairs, but also about the scientific and technical subjects in which both were engrossed. This became a life-long habit with the brothers Siemens. One early letter from William described a new kind of valve-gearing which he had invented for Cornish steam-engines. Then the germ of the idea of what was afterwards known as the 'chronometric governor' for steam-engines was likewise communicated in this way. Mr Pole says that his early letters were significant of the talent and capacity of the writer. 'They evince an acuteness of perception in mechanical matters, a power of close and correct reasoning, a sound judgment, a fertility of invention, and an ease and accuracy of expression which, in a youth of nineteen, who had only a few months' experience in a workshop, are extraordinary, and undoubtedly shadow forth the brilliant future he attained in the engineering world.'
Werner in 1841 had taken out a patent for his method of electro-gilding, while William early in 1843 paid his first visit to England, travelling by way of Hamburg. He took up his abode in a little inn called the 'Ship andStar,' at Sparrow Corner, near the Minories. In an address as President of the Midland Institute, Birmingham, on 28th October 1881, he related his first experiences in England, and how he secured his first success there.
Mr Siemens said: 'That form of energy known as the electric current was nothing more than the philosopher's delight forty years ago; its first application may be traced to this good town of Birmingham, where Mr George Richards Elkington, utilising the discoveries of Davy, Faraday, and Jacobi, had established a practical process of electroplating in 1842.... Although I was only a young student of Göttingen, under twenty years of age, who had just entered upon his practical career with a mechanical engineer, I joined my brother Werner Siemens, then a young lieutenant of artillery in the Prussian service, in his endeavour to accomplish electro-gilding.... I tore myself away from the narrow circumstances surrounding me, and landed at the East End of London, with only a few pounds in my pocket and without friends, but an ardent confidence of ultimate success within my breast.
'I expected to find some office in which inventions were examined into, and rewarded if found meritorious, but no one could direct me to such a place. In walking along Finsbury Pavement I saw written up in large letters, "So-and-So"—I forget the name—"undertaker," and the thought struck me that this must be the place I was in quest of; at any rate, I thought that a person advertising himself as an "undertaker" would not refuse to look into my invention, with the view of obtaining for me the sought for recognition or reward. On entering the place I soon convinced myself, however, that I came decidedly too soon for the kind of enterprise there contemplated.' By dint of perseverance, however, Siemens secured a letter from Messrs Poole and Carpmaell, of the Patent Office, to Mr Elkington of Birmingham. Elkington and his partnerJosiah Mason both met the young inventor in such a spirit of fairness that, as he says, he returned to his native country, and to his mechanical engineering, 'a comparative Crœsus.' After the lapse of forty years his heart still beat quick when thinking of this determining incident in his career.
The sum which Elkington paid him for his 'thermo-electrical battery' for depositing solutions of gold, silver, and copper was £1600, less £110 for the cost of the patent. Although quite successful at the time, other and cheaper processes speedily supplanted it; but the young German had gained a footing and the money he needed for future experiments. When he came back to Germany he was looked upon as quite a hero by his admiring family circle. It was indeed a creditable exploit for a youth of twenty. When he returned to England again in February 1844, he received so much encouragement from leading engineers and scientific men for his 'chronometric governor,' that he decided to settle permanently there, and he became a naturalised British subject in 1859. He joined with a civil engineer, named Joseph Woods, for the promotion and sale of his patents. 'Anastatic printing' was one of his early inventions, which, however, never became profitable. Then came schemes in paper-making, new methods of propelling ships, winged rockets, and locomotives on new principles, all of which were a continual drain on his own and his friends' resources without a corresponding return, so that in 1845 he took a situation and earned some money by railway work, which enabled him to pay another visit to Germany. In 1846, undaunted by previous failures, he threw himself heartily into the study of the action of heat as a power-giving agent, and invented an arrangement known as the 'regenerator' for saving certain portions of this waste. As afterwards applied to furnaces for iron, steel, zinc, glass, and other works, it waspronounced by Sir Henry Bessemer a beautiful invention, at once the most philosophic in principle, the most powerful in action, and the most economic of all the contrivances for producing heat by the combustion of coal. He now secured an appointment in 1849 with Fox & Henderson, Birmingham, at a fixed salary of £400 a year, and his interest in his patent. Here he profited largely by the experience gained, but the engagement terminated in 1851, when he afterwards settled as a civil engineer in 7 John Street, Adelphi, in March 1852.
His next great achievement was the production of steel direct from the raw ores by means of his regenerative furnace, which the President of the Board of Trade in 1883 mentioned in the House of Commons as one of the most valuable inventions ever produced under the protection of the English patent law, and he said further that it was then being used in almost every industry in the kingdom. Siemens had spent fourteen years in perfecting this regenerative furnace, and it took him other fourteen to utilise it, and perfect it in making steel direct from the raw ores. Martin of Sireil, who made one or two additions to the Siemens steel furnace, has been termed its inventor, but this claim has no foundation. What is known, however, as the 'Siemens-Martin process' is now competing very effectively with the Bessemer process. It consists essentially in first obtaining a bath of melted pig-iron of high quality, and then adding to this pieces of wrought-iron scrap or Bessemer scrap, such as crop ends of rails, shearings of plates, &c. These, though practically non-infusible in large quantities by themselves, become dissolved or fused in such a bath if added gradually. To the bath of molten metal thus obtained spiegeleisen or ferro-manganese is added to supply the required carbon and to otherwise act as in the Bessemer converter. The resultis tested by small ladle samples, and when it is of the desired quality a portion is run off, leaving sufficient bath for the continuation of the process.
Siemens took out his patent for the 'open hearth' process of steel-making (the Forth Bridge is built of steel made in this way) in 1861, and four years later erected sample steel works at Birmingham. The engineer of the London and North-Western Railway adopted his system at Crewe in 1868, and the Great Western Railway works followed. In 1869 this process was being carried out on a large scale at the works of the Landore-Siemens Steel Company and elsewhere in England, as well as at various works on the Continent, including Krupp's, at Essen.
In 1862, Siemens was elected a Fellow of the Royal Society, and in 1874 was presented with the Royal Albert Medal, and in 1875 with the Bessemer Medal in recognition of his researches and inventions in heat and metallurgy. He filled the president's chair in the three principal engineering and telegraphic societies of Great Britain, and in 1882 was President of the British Association. As manager in England of the firm of Siemens Brothers, Sir William Siemens was actively engaged in the construction of overland and submarine telegraphs. The steamshipFaradaywas specially designed by him for cable-laying. In addition to his labours in connection with electric-lighting, Sir William Siemens also successfully applied, in the construction of the Portrush Electric Tramway, which was opened in 1883, electricity to the production of locomotion. In his regenerative furnace, as we have seen, he utilised in an ingenious way the heat which would otherwise have escaped with the products of combustion. The process was subsequently applied in many industrial processes, but notably by Siemens himself in the manufacture of steel.
The other inventions and researches of this wonderful man include a water-meter; a thermometer or pyrometer, which measures by the change produced in the electric conductivity of metals; the bathometer, for measuring ocean depths by variations in the attraction exerted on a delicately suspended body; and the hastening of vegetable growth by use of the electric light. He was knighted in April 1883, and died on November 19 of the same year. There is a memorial window to his memory in Westminster Abbey.
As the elder brother of Sir William Siemens was so closely connected with him in business life, and may be said to have encouraged and led him into the walk of life in which he excelled, he also deserves a notice here.Werner Von Siemens, engineer and electrician, was born December 13, 1816, at Lenthe in Hanover. In 1834 he entered the Prussian Artillery; and in 1844 was put in charge of the artillery workshops at Berlin. He early showed scientific tastes, and in 1841 took out his first patent for galvanic silver and gold plating. By selling the right of using his process he made 40 louis d'or, which supplied him with the means for further experiments. During the Schleswig-Holstein war, he attracted considerable attention by using electricity for the firing of the mines which had been laid for the defence of Kiel harbour. He was of peculiar service in developing the telegraphic service in Prussia, and discovered in this connection the valuable insulating property of gutta-percha for underground and submarine cables. In 1849 he left the army, and shortly after the service of the state altogether, and devoted his energies to the construction of telegraphic and electrical apparatus of all kinds. The well-known firm of Siemens and Halske was established in 1847 in Berlin, and to them the Russian government entrusted the construction of the telegraph lines in that country. Subsequently branches were formed, chiefly under the management of the younger brothers of Werner Siemens, in St Petersburg (1857), in London (1858), in Vienna (1858), and in Tiflis (1863). In 1857, Siemens accomplished the remarkable feat of successfully laying a cable in deep water, at a depth of more than 1000 fathoms. This was between Sardinia and Bona. Shortly after he superintended the laying of cables in the Red Sea; and these successful experiments soon led to the greatest undertaking of all, the connection of America with Europe. Besides devising numerous useful forms of galvanometers and other electrical instruments of precision, Werner Siemens was one of the discoverers of the principle of the self-acting dynamo. He also made valuable determinations of the electrical resistance of different substances, the resistance of a column of mercury, one metre long, and one square millimetre cross section at 0°C., being known as the Siemens Unit. His numerous scientific and technical papers, written for the various journals, were republished in collected form in 1881. In 1886 he gave 500,000 marks for the founding of an imperial institute of technology and physics; and in 1888 he was ennobled. He died at Berlin, 6th December 1892. A translation of hisPersonal Recollectionsby Coupland appeared in 1893.
Space forbids us mentioning other worthy names in the steel and iron trade, although we cannot pass by Sir John Brown, founder of the Atlas Steel-works, Sheffield (1857), and one of the first to adopt the Bessemer process. He was also the pioneer of armour-plate making. The immense strides he made in business may be judged from the fact that when he started in 1857 his employees numbered 200, with a turnover of £3000 a year; in 1867 they numbered 4000, and the turnover was £1,000,000.The weekly pay roll amounted to £7000 in 1883, and when he handed over the business to his successors, he was paid £200,000 for the goodwill.
One of the largest iron and steel manufacturing establishments in the world is that founded by the late Alfred Krupp, the famous German cannon-founder, whose name is so well known in connection with modern improvements in artillery. His principal works are situated at Essen, in Prussia, in the midst of a district productive of both iron and coal. The town of Essen, which at the beginning of the present century contained less than four thousand inhabitants, has become an important industrial centre, with a population of nearly eighty thousand persons, this increase being chiefly due to the growth of the ironworks, and the consequent demand for labour. In the vicinity of the town, numerous coal and iron mines, many of which are owned by the Krupp firm, are in active working, and furnish employment to the large population of the surrounding district. Much of the output of iron ore and coal from these mines is destined for consumption in the vast Krupp works within the town. Those works had their origin in a small iron forge established at Essen in the year 1810 by Frederick Krupp, the father of Alfred Krupp. The elder Krupp was not prosperous; and a lawsuit in which he became involved, and which lasted for ten years, though finally decided in his favour, reduced him nearly to bankruptcy. He died in 1826, in impoverished circumstances, leaving a widow and three sons, the eldest of whom was Alfred, aged fourteen. The business was continued by the widow, who managed, though with difficulty, to procure a good education for her sons. Whenthe eldest, Alfred, took control of the works in 1848, he found there, as he himself has described, 'three workmen, and more debts than fortune.'
Krupp's subsequent career affords a remarkable instance of success attained, despite adverse circumstances, by sheer force of ability and energy, in building up a colossal manufacturing business from a humble beginning. On his death in 1887 his only son succeeded him. At the present time, Krupp's works within the town of Essen occupy more than five hundred acres, half of which area is under cover. In 1895, the number of persons in his employ was 25,300, and including members of their families, over 50,000. Of the army of workers, about 17,000 were employed at the works in Essen, the remainder being occupied in the 550 iron and coal mines belonging to the firm, or at the branch works at Sayn Neuwied, Magdeburg, Duisburg, and Engers; or in the iron-mines at Bilbao, in Spain, which produce the best ores. In Krupp's Essen works there are one hundred and twelve steam-hammers, ranging in weight from fifty tons down to four hundred pounds. There are 15 Bessemer converters, 18 Martin-furnaces, 420 steam-engines—representing together 33,150 horse-power—and twenty-one rolling trains; the daily consumption of coal and coke being 3100 tons by 1648 furnaces. The average daily consumption of water, which is brought from the river Ruhr by an aqueduct, is 24,700 cubic metres. The electric light has been introduced, and the work ceases entirely only on Sunday and two or three holidays. Connected with the Essen works are fifty miles of railway, employing thirty-five locomotives and over 1000 wagons. There are two chemical laboratories; a photographic and lithographic studio; a printing-office, with steam and hand presses; and a bookbinding room, besides tile-works, coke-works, gas-works, &c.
Though, in the popular mind, the name of Krupp isusually associated with the manufacture of instruments of destruction, yet two-thirds of the work done in his establishment is devoted to the production of articles intended for peaceful uses. The various parts of steam-engines, both stationary and locomotive; iron axles, bridges, rails, wheel-tires, switches, springs, shafts for steamers, mint-dies, rudders, and parts of all varieties of iron machinery, are prepared here for manufacturers. The production is, in Dominie Sampson's phrase, 'prodigious.' In one day the works can turn out 2700 rails, 350 wheel-tires, 150 axles, 180 railway wheels, 1000 railway wedges, 1500 bombshells. In a month they have produced 250 field-pieces, thirty 5.7-inch cannon, fifteen 9.33-inch cannon, eight 11-inch cannon, one 14-inch gun, the weight of the last named being over fifty tons, and its length twenty-eight feet seven inches. Till the end of 1894 the firm has produced 25,000 cannon for thirty-four different states.
Alfred Krupp devoted much attention to the production of steel of the finest quality, and was the first German manufacturer who succeeded in casting steel in large masses. In 1862 he exhibited in London an ingot of finest crucible steel weighing twenty-one tons. Its dimensions were nine feet high by forty-four inches diameter. The uniformity of quality of this mass of metal was proven by the fact that when broken across it showed no seam or flaw, even when examined with a lens. The firm can now make such homogeneous blocks of seventy-five tons weight if required. Such ingots are formed from the contents of a great number of small crucibles, each containing from fifty to one hundred pounds of the metal. The recent developments of the manufacture of steel by the open-hearth process have removed all difficulty in procuring the metal in masses large enough for all requirements, and of a tensile strength so high as thirty-three to thirty-seven tons to the square inch. Crucible steel, however, though moreexpensive, still holds its place as the best and most reliable that can be produced; and nothing else is ever used in the construction of a Krupp gun. By the perfected methods in use at the Essen works, such steel can be made of a tensile strength of nearly forty tons to the square inch, and of marvellous uniformity of quality. The ores used in the Krupp works for making the best steel are red hæmatite and spathic ore, with a certain proportion of ferro-manganese. The crucibles employed are formed of a mixture of plumbago and fire-clay, shaped by a mould into a cylindrical jar some eighteen inches in height, and baked in a kiln. When in use, they are filled with small bars of puddled metal, mixed with fragments of marble brought from Villmar, on the Lahn. They are then shovelled into large furnaces, whose floors are elevated three or four feet above the ground-level. In the earthen floor of the immense room containing the furnaces are two lines of pits, one set to receive the molten metal, the other intended for the red-hot crucibles when emptied of their contents. When the crucibles have undergone sufficient heating, the furnace doors are opened simultaneously at a given signal, and the attendant workmen draw out the crucibles with long tongs, and rapidly empty them into the pits prepared for the reception of the metal. The empty crucibles when cooled are examined, and if found unbroken, are used again; but if damaged, as is usually the case, are ground up, to be utilised in making new ones.
The production of steel by this method furnishes employment for eight or nine hundred men daily in the Krupp works. The Bessemer process for converting iron into steel is also largely used there for making steel for certain purposes. All material used in the different classes of manufactures is subjected at every stage to extreme and exact tests; the standards being fixed withreference to the purpose to which the metal is to be applied, and any material that proves faulty when suitably tested is rigorously rejected.
The guns originally manufactured by the Krupp firm were formed from solid ingots of steel, which were bored, turned, and fashioned as in the case of cast-iron smooth-bore cannon. With the development of the power of artillery, the greater strain caused by the increased powder-charges and by the adoption of rifling—involving enhanced friction between the projectile and the bore—had the result of demonstrating the weakness inherent in the construction of a gun thus made entirely from one solid forging, and that plan was eventually discarded. Artillerists have learnt that the strain produced by an explosive force operating in the interior of a cannon is not felt equally throughout the thickness of the metal from the bore to the exterior, but varies inversely as the square of the distance of each portion of the metal from the seat of effort. For example, in a gun cast solid, if two points be taken, one at the distance of one inch from the bore, and the other four inches from the bore, the metal at the former point will during the explosion be strained sixteen times as much as that at the distance of four inches. The greater the thickness of the material, the greater will be the inequality between the strains acting at the points respectively nearest to and farthest from the interior. The metal nearest the seat of explosion may thus be strained beyond its tensile strength, while that more remote is in imperfect accord with it. In such a case, disruption of the metal at the inner surface ensues, and extends successively through the whole thickness to the exterior, thus entailing the destruction of the gun.
This source of weakness is guarded against by the construction of what is termed the built-up gun, in which the several parts tend to mutual support. This gun consistsof an inner tube, encircled and compressed by a long 'jacket' or cylinder, which is shrunk around the breech portion with the initial tension due to contraction in cooling. Over the jacket and along the chase, other hoops or cylinders are shrunk on successively, in layers, with sufficient tension to compress the parts enclosed. The number and strength of these hoops are proportionate to the known strain that the bore of the gun will have to sustain. The tension at which each part is shrunk on is the greater as the part is farther removed from the inner tube; the jacket, for example, being shrunk on at less tension than the outer hoops. The inner tube, on receiving the expansive force of the explosion, is prevented by the compression of the jacket from being forced up to its elastic limit; and the jacket in its turn is similarly supported by the outer hoops; and on the cessation of the internal pressure the several parts resume their normal position.
This system of construction originated in England, and is now in general use. The first steel guns on this principle were those designed by Captain Blakely and Mr J. Vavasseur, of the London Ordnance Works. At the Exhibition of 1862, a Blakely 8.5-inch gun, on the built-up system, composed wholly of steel, was a feature of interest in the Ordnance section. The plan devised by Sir W. Armstrong, and carried into effect for a series of years at Woolwich and at the Armstrong Works at Elswick, consisted in enclosing a tube of steel within a jacket of wrought iron, formed by coiling a red-hot bar round a mandrel. The jacket was shrunk on with initial tension, and was fortified in a similar manner by outer hoops of the same metal. The want of homogeneity in this gun was, however, a serious defect, and ultimately led to its abolition. The difference in the elastic properties of the two metals caused a separation, after repeated discharges,between the steel tube and its jacket, with the result that the tube cracked from want of support. Both at Woolwich and at Elswick (described on a later page), therefore, the wrought-iron gun has given place to the homogeneous steel built-up gun, which is also the form of construction adopted by the chief powers of Europe and by the United States of America.
The failure of some of his solid-cast guns led Krupp, about 1865, to the adoption of the built-up principle. With few exceptions, the inner tube of a Krupp gun is forged out of a single ingot, and in every case without any weld. The ingot destined to form the tube has first to undergo a prolonged forging under the steam-hammers, by which the utmost condensation of its particles is effected. It is then rough-bored and turned, and subsequently carefully tempered in oil, whereby its elasticity and tensile strength are much increased. It is afterwards fine-bored and rifled, and its powder-chamber hollowed out. The latter has a somewhat larger diameter than the rest of the bore, this having been found an improvement. The grooves of the rifling are generally shallow, and they widen towards the breech, so that the leaden coat of the projectile is compressed gradually and with the least friction. The jacket and hoops of steel are forged and rolled, without weld, and after being turned and tempered, are heated and shrunk around the tube in their several positions, the greatest strength and thickness being of course given to the breech end, where the force of explosion exerts the utmost strain. The completed gun is mounted on its appropriate carriage, and having been thoroughly proved and tested and fitted with the proper sights, is ready for service. The testing range is at Meppen, where a level plain several miles in extent affords a suitable site for the purpose.
For many years all guns of the Krupp manufacture havebeen on the breech-loading system, and he has devoted much time and ingenuity to perfecting the breech arrangements. The subject of recoil has also largely occupied his attention. In the larger Krupp guns the force of recoil is absorbed by two cylinders, filled with glycerine and fitted with pistons perforated at the edges. The pistons are driven by the shock of the recoil against the glycerine, which is forced through the perforations. In England a similar arrangement of cylinders, containing water as the resisting medium, has been found effective; and in America, petroleum is employed for the same purpose. The advantages of the use of glycerine are that in case of a leak it would escape too slowly to lose its effect at once, and it is also more elastic than water, and is less liable to become frozen.
The resources of Krupp's establishment are equal to the production of guns of any size that can conceivably be required. He has made guns of one hundred and nineteen tons weight. The portentous development of the size and power of modern ordnance is exemplified by these guns and the Armstrong guns of one hundred and eleven tons made at Elswick. Amongst the class of modern cannon, one of the most powerful is Krupp's seventy-one-ton gun. This, like all others of his make, is a breech-loader. Its dimensions are—length, thirty-two feet nine inches; diameter at breech end, five feet six inches; length of bore, twenty-eight feet seven inches; diameter of bore, 15.75 inches; diameter of powder-chamber, 17.32 inches. The internal tube is of two parts, exactly joined; and over this are four cylinders, shrunk on, and a ring round the breech. Its rifling has a uniform twist of one in forty-five. It cannot possibly be fired until the breech is perfectly closed. Its maximum charge is four hundred and eighty-five pounds of powder, and a chilled iron shell of seventeen hundred and eight pounds.

Krupp did much to promote the welfare and comfort of his workpeople. For their accommodation, he erected around Essen nearly four thousand family dwellings, in which more than sixteen thousand persons reside. The dwellings are in suites of three or four comfortable rooms, with good water-arrangements; and attached to each building is a garden, large enough for the children to play in. There are one hundred and fifty dwellings of a better kind for officials in the service of the firm. Boarding-houses have also been built for the use of unmarried labourers, of whom two thousand are thus accommodated. Several churches, Protestant and Catholic, have also been erected, for the use of his workmen and their families. There have likewise been provided two hospitals, bathing establishments, a gymnasium, an unsectarian free school, and six industrial schools—one for adults, two for females. In the case of the industrial schools, the fees are about two shillings monthly, but the poorest are admitted free. A Sick Relief and Pensions Fund has been instituted, and every foreman and workman is obliged to be a member. The entrance fee is half a day's pay, the annual payment being proportioned to the wages of the individual member; but half of each person's contribution is paid by the firm. There are three large surgeries; and skilful physicians and surgeons, one of whom is an oculist, are employed at fixed salaries. For a small additional fee each member can also secure free medical aid for his wife and children. The advantages to members are free medical or surgical treatment in case of need, payment from the fund of funeral expenses at death, pensions to men who have been permanently disabled by injuries while engaged in the works, pensions to widows of members, and temporary support to men who are certified by two of the physicians as unable to work. The highest pension to men is five pounds monthly, the average being about two poundssixteen shillings monthly. The average pension to widows is about one pound fourteen shillings monthly.
The firm have made special arrangements with a number of life insurance companies whereby the workmen can, if they choose, insure their lives at low rates. They have formed a Life Insurance Union, and endowed it with a reserve fund of three thousand pounds, from which aid is given to members needing assistance to pay their premiums. An important institution in Essen is the great Central Supply Store, established and owned by the firm, where articles of every description—bread, meat, and other provisions, clothing, furniture, &c.—are sold on a rigidly cash system at cost price. Connected with the Central Store are twenty-seven branch shops, in positions convenient for the workpeople, placing the advantages of the system within the easy reach of all.
The original name, 'Frederick Krupp,' has been retained through all vicissitudes of fortune as the business title of the firm. The small dwelling in which Alfred Krupp was born is still standing, in the midst of the huge workshops that have grown up around it, and is preserved with the greatest care. At his expense, photographs of it were distributed among his workmen, each copy bearing the following inscription, dated Essen, February 1873: 'Fifty years ago, this primitive dwelling was the abode of my parents. I hope that no one of our labourers may ever know such struggles as have been required for the establishment of these works. Twenty-five years ago that success was still doubtful which has at length—gradually, yet wonderfully—rewarded the exertions, fidelity, and perseverance of the past. May this example encourage others who are in difficulties! May it increase respect for small houses, and sympathy for the larger sorrows they too often contain. The object of labour should be the common weal. If work bring blessing, then is labourprayer. May every one in our community, from the highest to the lowest, thoughtfully and wisely strive to secure and build his prosperity on this principle! When this is done, then will my greatest desire be realised.'
Germany has become a formidable competitor to Great Britain in the iron and steel trade, and German steel rails, girders, and wire come in freely to this country. From reports we learn that Great Britain produced in 1882 8½ million tons of iron and 5 million tons of finished iron and steel, while the production of Germany was then less than 3½ and 2½ million tons respectively. English production had fallen to 7½ million tons of iron and 4 million tons of finished iron and steel in 1895, while Germany had risen to 5 million tons and 6 million tons respectively.
Contrary to what has been commonly believed, it appears that the difference all round in wages amongst ironworkers, as between England and Germany, is not great.
Chicago, Pittsburg, Buffalo, and New York are the chief centres of the American iron and steel trade, the production of pig-iron in 1895 being about 9¼ million tons, whereas in 1880 it was well under 4 million. At present over 4 millions of tons are produced of Bessemer pig-iron.
Josiah Wedgwood and the Wedgwood Ware—Worcester Porcelain.
W
hen Mr Godfrey Wedgwood, a member of the famous firm of potters at Etruria, near Burslem, Staffordshire, went to work about forty years ago, his famous ancestor and founder of the world-famed Wedgwood ware was still named amongst the workmen as 'Owd Wooden Leg.' A son of Mr Godfrey Wedgwood, now in the firm, is the fifth generation in descent, and the manufactory is still carried on in the same buildings erected by Josiah Wedgwood one hundred and twenty years ago.
One hundred years ago Josiah Wedgwood, the creator of British artistic pottery, passed away at Etruria, near Burslem, surrounded by the creations of his own well-directed genius and industry, having 'converted a rude and inconsiderable manufacture into an elegant art and an important part of national commerce.' His death took place on 3d January 1795, the same year in which Thomas Carlyle saw the light at Ecclefechan, and one year and a half before the death of Burns at Dumfries. During fifty years of his working life, largely owing to his own successful efforts, he had witnessed the output of the Staffordshire potteries increased fivefold, and his wareswere known and sold over Europe and the civilised world. In the words of Mr Gladstone, his characteristic merit lay 'in the firmness and fullness with which he perceived the true law of what we may call Industrial Art, or, in other words, of the application of the higher art to Industry.' Novalis once compared the works of Goethe and Wedgwood in these words: 'Goethe is truly a practical poet. He is in his works what the Englishman is in his wares, perfectly simple, neat, fit, and durable. He has played in the German world of literature the same part that Wedgwood has played in the English world of art.'

Long ago, in his sketch of Brindley and the early engineers, Dr Smiles had occasion to record the important service rendered by Wedgwood in the making of the Grand Trunk Canal—towards the preliminary expense of which he subscribed one thousand pounds—and in the development of the industrial life of the Midlands. Since that time Smiles has himself published a biography of Wedgwood, to which we are here indebted.
More than once it has happened that the youngest of thirteen children has turned out a genius. It was so in the case of Sir Richard Arkwright, and it turned out to be so in the case of Josiah Wedgwood, the youngest of the thirteen children of Thomas Wedgwood, a Burslem potter, and of Mary Stringer, a kind-hearted but delicate, sensitive woman, the daughter of a nonconformist clergyman. The town of Burslem, in Staffordshire, where Wedgwood saw the light in 1730, was then anything but an attractive place. Drinking and cock-fighting were the common recreations; roads had scarcely any existence; the thatched hovels had dunghills before the doors, while the hollows from which the potter's clay was excavated were filled with stagnant water, and the atmosphere of the whole place was coarse and unwholesome, and a most unlikely nursery of genius.
It is probable that the first Wedgwoods take their name from the hamlet of Weggewood in Staffordshire. There had been Wedgwoods in Burslem from a very early period, and this name occupies a large space in the parish registers during the seventeenth and eighteenth centuries; of the fifty small potters settled there, many bore this honoured name. The ware consisted of articles in common use, such as butter-pots, basins, jugs, and porringers. The black glazed and ruddy pottery then in use was much improved after an immigration of Dutchmen and Germans. The Elers, who followed the Prince of Orange, introduced the Delft ware and the salt glaze. They produced a kind of red ware, and Egyptian black; but disgusted at the discovery of their secret methods by Astbury and Twyford, they removed to Chelsea in 1710. An important improvement was made by Astbury, that of making ware white by means of burnt flint. Samuel Astbury, a son of this famous potter, married an aunt of Josiah Wedgwood. But the art was then in its infancy, not more than one hundred people being employed in this way in the district of Burslem, as compared with about ten thousand now, with an annual export of goods amounting to about two hundred thousand pounds, besides what are utilised in home-trade. John Wesley, after visiting Burslem in 1760, and twenty years later in 1781, remarked how the whole face of the country had been improved in that period. Inhabitants had flowed in, the wilderness had become a fruitful field, and the country was not more improved than the people.
All the school education young Josiah received was over in his ninth year, and it amounted to only a slight grounding in reading, writing, and arithmetic. But his practical or technical education went on continually, while he afterwards supplemented many of the deficiencies of early years by a wide course of study. After the death ofhis father, he began the practical business of life as a potter in his ninth year, by learning the throwing branch of the trade. The thrower moulds the vessel out of the moist clay from the potter's wheel into the required shape, and hands it on to be dealt with by the stouker, who adds the handle. Josiah at eleven proved a clever thrower of the black and mottled ware then in vogue, such as baking-dishes, pitchers, and milk-cans. But a severe attack of virulent smallpox almost terminated his career, and left a weakness in his right knee, which developed, so that this limb had to be amputated at a later date. He was bound apprentice to his brother Thomas in 1744, when in his fourteenth year; but this weak knee, which hampered him so much, proved a blessing in disguise, for it sent him from the thrower's place to the moulder's board, where he improved the ware, his first effort being an ornamental teapot made of the ochreous clay of the district. Other work of this period comprised plates, pickle-leaves, knife-hafts, and snuff-boxes. At the same time he made experiments in the chemistry of the material he was using. Wedgwood's great study was that of different kinds of colouring matter for clays, but at the same time he mastered every branch of the art. That he was a well-behaved young man is evident from the fact that he was held up in the neighbourhood as a pattern for emulation.

But his brother Thomas, who moved along in the old rut, had small sympathy with all this experimenting, and thought Josiah flighty and full of fancies. After remaining for a time with his brother, at the completion of his apprenticeship Wedgwood became partner in 1752, in a small pottery near Stoke-upon-Trent: soon after, Mr Whieldon, one of the most eminent potters of the day, joined the firm. Here Wedgwood took pains to discover new methods and striking designs, as trade was thendepressed. New green earthenware was produced, as smooth as glass, for dessert service, moulded in the form of leaves; also toilet ware, snuff-boxes, and articles coloured in imitation of precious stones, which the jewellers of that time sold largely. Other articles of manufacture were blue-flowered cups and saucers, and varicoloured teapots. Wedgwood, on the expiry of his partnership with Whieldon, started on his own account in his native Burslem in 1760. His capital must have been small, as the sum of twenty pounds was all he had received from his father's estate. He rented Ivy House and Works at ten pounds a year, and engaged his second-cousin, Thomas, as workman at eight shillings and sixpence a week. He gradually acquired a reputation for the taste and excellence of design of his green glazed ware, his tortoiseshell and tinted snuff-boxes, and white medallions. A specially designed tea-service, representing different fruits and vegetables, sold well, and, as might be expected, was at once widely imitated. He hired new works on the site now partly occupied by the Wedgwood Institute, and introduced various new tools and appliances. His kilns for firing his fine ware gave him the greatest trouble, and had to be often renewed. James Brindley, when puzzled in thinking out some engineering problem, used to retire to bed and work it out in his head before he got up. Sir Josiah Mason, the Birmingham pen-maker, used to simmer over in his mind on the previous night the work for the next day. Wedgwood had a similar habit, which kept him often awake during the early part of the night. Probably owing to the fortunate execution of an order through Miss Chetwynd, maid of honour to Queen Charlotte, of a complete cream service in green and gold, Wedgwood secured the patronage of royalty, and was appointed Queen's Potter in 1763. His Queen's ware became popular, and secured him much additional business.
An engine lathe which he introduced greatly forwarded his designs; and the wareroom opened in London for the exhibition of his now famous Queen's ware, Etruscan vases, and other works, drew attention to the excellence of his work. He started works besides at Chelsea, supervised by his partner Bentley, where modellers, enamellers, and artists were employed, so that the cares of his business, 'pot-making and navigating'—the latter the carrying through of the Grand Trunk Canal—entirely filled his mind and time at this period. So busy was he, that he sometimes wondered whether he was an engineer, a landowner, or a potter. Meanwhile, a step he had no cause to regret was his marriage in 1764 to Sarah Wedgwood, no relation of his own, a handsome lady of good education and of some fortune.
Wedgwood had begun to imitate the classic works of the Greeks found in public and private collections, and produced his unglazed black porcelain, which he named Basaltes, in 1766. The demand for his vases at this time was so great that he could have sold fifty or one hundred pounds' worth a day, if he had been able to produce them fast enough. He was now patronised by royalty, by the Empress of Russia, and the nobility generally. A large service for Queen Charlotte took three years to execute, as part of the commission consisted in painting on the ware, in black enamel, about twelve hundred views of palaces, seats of the nobility, and remarkable places. A service for the Empress of Russia took eight years to complete. It consisted of nine hundred and fifty-two pieces, of which the cost was believed to have been three thousand pounds, although this scarcely paid Wedgwood's working expenses.
Prosperity elbowed Wedgwood out of his old buildings in Burslem, and led him to purchase land two miles away, on the line of the proposed Grand Trunk Canal, wherehis flourishing manufactories and model workmen's houses sprang up gradually, and were namedEtruria, after the Italian home of the famous Etruscans, whose work he admired and imitated. His works were partly removed thither in 1769, and wholly in 1771. At this time he showed great public spirit, and aided in getting an Act of Parliament for better roads in the neighbourhood, and backed Brindley and Earl Gower in their Grand Trunk Canal scheme, which was destined, when completed, to cheapen and quicken the carriage of goods to Liverpool, Bristol, and Hull. The opposition was keen: and Wedgwood issued a pamphlet showing the benefits which would accrue to trade in the Midlands by the proposed waterway. When victory was secured, after the passing of the Act there was a holiday and great rejoicing in Burslem and the neighbourhood, and the first sod of the canal was cut by Wedgwood, July 26, 1766. He was also appointed treasurer of the new undertaking, which was eleven years in progress. Brindley, the greatest engineer then in England, doubtless sacrificed his life to its success, as he died of continual harassment and diabetes at the early age of fifty-six. Wedgwood had an immense admiration for Brindley's work and character. In the prospect of spending a day with him, he said: 'As I always edify full as much in that man's company as at church, I promise myself to be much wiser the day following.' Like Carlyle, who whimsically put the builder of a bridge before the writer of a book, Wedgwood placed the man who designed the outline of a jug or the turn of a teapot far below the creator of a canal or the builder of a city.
In the career of a man of genius and original powers, the period of early struggle is often the most interesting. When prosperity comes, after difficulties have been surmounted, there is generally less to challenge attention. But Wedgwood's career was still one of continual progressup to the very close. His Queen's ware, made of the whitest clay from Devon and Dorset, was greatly in demand, and much improved. The fine earthenwares and porcelains which became the basis of such manufactures were originated here. Young men of artistic taste were employed and encouraged to supply designs, and a school of instruction for drawing, painting, and modelling was started. Artists such as Coward and Hoskins modelled the 'Sleeping Boy,' one of the finest and largest of his works. John Bacon, afterwards known as a sculptor, was one of his artists, as also James Tassie of Glasgow. Wedgwood engaged capable men wherever they could be found. For his Etruscan models he was greatly indebted to Sir W. Hamilton. Specimens of his famous portrait cameos, medallions, and plaques will be found in most of our public museums.
The general health of Wedgwood suffered so much between 1767 and 1768 that he decided to have the limb which had troubled him since his boyhood amputated. He sat, and without wincing, witnessed the surgeons cut off his right leg, for there were then no anæsthetics. 'Mr Wedgwood has this day had his leg taken off,' wrote one of the Burslem clerks at the foot of a London invoice, 'and is as well as can be expected after such an execution.' His wife was his good angel when recovering, and acted as hands and feet and secretary to him; while his partner Bentley (formerly a Liverpool merchant) and Dr Darwin were also kind; and he was almost oppressed with the inquiries of many noble and distinguished persons during convalescence. He had to be content with a wooden leg now. 'Send me,' he wrote to his brother in London, 'by the next wagon a spare leg, which you will find, I believe, in the closet.' He lived to wear out a succession of wooden legs.
Indifference and idleness he could not tolerate, and his fine artistic sense was offended by any bit of imperfect work. In going through his works, he would lift the stick upon which he leaned and smash the offending article, saying, 'This won't do for Josiah Wedgwood.' All the while he had a keen insight into the character of his workmen, although he used to say that he had everything to teach them, even to the making of a table plate.
He was no monopolist, and the only patent he ever took out was for the discovery of the lost art of burning in colours, as in the Etruscan vases. 'Let us make all the good, fine, and new things we can,' he said to Bentley once; 'and so far from being afraid of other people getting our patterns, we should glory in it, and throw out all the hints we can, and if possible, have all the artists in Europe working after our models.' By this means he hoped to secure the goodwill of his best customers and of the public. At the same time he never sacrificed excellence to cheapness. As the sale of painted Etruscan ware declined, his Jasper porcelain—so called from its resemblance to the stone of that name—became popular. The secret of its manufacture was kept for many years. It was composed of flint, potter's clay, carbonate of barytes, andterra ponderosa. This and the Jasper-dip are in several tones and hues of blue; also yellow, lilac, and green. He called in the good genius of Flaxman in 1775; and, for the following twelve years, the afterwards famous sculptor did an immense amount of work and enhanced his own and his patron's reputation. Flaxman did some of his finest work in this Jasper porcelain. Some of Flaxman's designs Wedgwood could scarcely be prevailed upon to part with. A bas-relief of the 'Apotheosis of Homer' went for seven hundred and thirty-five pounds at the sale of his partner Bentley;and the 'Sacrifice to Hymen,' a tablet in blue and white Jasper (1787), brought four hundred and fifteen pounds. The first named is now in the collection of Lord Tweedmouth. Wedgwood's copy of the Barberini or Portland Vase was a great triumph of his art. This vase, which had contained the ashes of the Roman Emperor Alexander Severus and his mother, was of dark-blue glass, with white enamel figures. It now stands in the medal room of the British Museum alongside a model by Wedgwood. It stands 10 inches high, and is the finest specimen of an ancient cameo cut-glass vase known. It was smashed by a madman in 1845, but was afterwards skilfully repaired. Wedgwood made fifty copies in fine earthenware, which were originally sold at 25 guineas each. One of these now fetches £200. The vase itself once changed hands for eighteen hundred guineas, and a copy fetched two hundred and fifteen guineas in 1892.
