vy agent, in which he is said to have realized considerable profits. It was while conducting this business that he became aware of the inferiority of British iron compared with that obtained from foreign countries. The English wrought iron was considered so bad that it was prohibited from all government supplies, while the ca

teps he arrived at results of so much importance to the British iron trade, no one can now tell. All that is known is, that about the year 1775 he relinquished his business as a navy agent, and took a lease of certain premises at Fontley, near Fareham, at the north-western c

until it was reduced to a loop and drawn out into bar-iron under a common forge-hammer. Then the brothers Cranege, in 1766, adopted the reverberatory or air furnace, in which they placed the pig or cast iron, and without blast or the addition of anything more than common raw pit-coal, converted the same into good malleable iron, which being taken red hot from the reverberatory furnace to the forge hammer, was drawn into bars according to the will of the workman. Peter Onions of Merthyr Tydvil, in 1783, carried the manufacture a stage further, as described by him in his patent of that year. Having charged his furnace ("bound with iron work and well annealed") with pig or fused cast iron from the smelting furnace, it was closed up and the doors were luted with sand. The fire was urged by a blast admitt

course of a few years, to raise it to the highest state of prosperity. As early as 1786, Lord Sheffield recognised the great national importance of Cort's improvements in the following words:-"If Mr. Cort's very ingenious and meritorious improvements in the art of making and working iron, the steam-engine of Boulton and Watt, and Lord Dundonald's discovery of making coke at half the present price, should all succeed, it is not asserting to

ering so as to be thinner at one end than the other, laid over one another in the manner of bricks in buildings, so that the ends should everywhere overlay each other. The faggots so prepared, to the amount of half a ton more or less, were then to be put into a common air or balling furnace, and brought to a welding heat, which was accomplished by his method in a much shorter time than in any hollow fire; and when the heat was perfect, the faggots were then brought under a forge-hammer of great size and weight, and welded into a solid mass. Mr. Cort alleges in the specification that iron for "larger uses" thus finished, is in all respect's possessed of the highest degree of perfection; and that the fire in the balling furnace is better suited, from its regularity and penetrating quality, t

d combining and applying them in a more effective practical form than had ever been done before. This power of apprehending the best methods, and embodying the details in one complete whole, marks the practical, clear-sighted man, and in certain cases amounts almost to a g

iron. Cort, however, carried the process further, and made it more effectual in all respects. His method may be thus briefly described: the bottom of the reverberatory furnace was hollow, so as to contain the fluid metal, introduced into it by ladles; the heat being kept up by pit-coal or other fuel. When the furnace was charged, the doors were closed until the metal was sufficiently fused, when the workman opened an aperture and worked or stirred about the metal with iron bars, when an ebullition took place, during the co

had an extraordinary effect upon the production of iron. It created a largely increased demand for the article for the purposes of the shafting and machinery which it was employed to drive; while at the same time it cleared pits of water which before were unworkable, and by being extensively applied to the blowing of iron-furnaces and the working of the rolling-mills, it thus gave a still further impetus to the manufacture of the metal. It would be beside our purpose to enter into any statistical detail on the subject; but it will be sufficient to state that the production of iron, which in the early part of last century amounted to

very of a new mechanical Power, in reversing the action of the wedge, by the application of force to four surfaces, so as to elongate a mass, instead of applying force to a mass to divide the four surfaces." One of the best authorities in the iron tra

then (in 1787) forging only ten tons of bar-iron weekly under the hammer; and when he saw the superior processes invented by Cort he readily entered into a contract with him to work under his patents at ten shillings a ton royalty, In 1812 a letter from Mr. Crawshay to the Secretary of Lord Sheffield was read to the House of Commons, descriptive of his method of working iron, in which he said, "I took it from a Mr. Cort, who had a little mill at Fontley in Hampshire: I have thus acquainted you with my method, by which I am now making more than ten thous

his public accounts to the extent of 39,676L, and his books and papers were immediately taken possession of by the Government. On examination it was found that the debts due to Jellicoe amounted to 89,657L, included in which was a sum of not less than 54,853L. owing to him by the Cort partnership. In the public investigation which afterwards took place, it appeared that the capital possessed by Cort being insufficient to enable him to pursue his experiments, which were of a very expensive character, Adam Jellicoe had advanced money from time to time for the purpose, securing himself by a deed of agreement entitling him to one-half the stock and profits of all his contracts; and in further consideration of the capital advanced by Jellicoe beyond his equal share, Cort subsequently assigned to him all his patent rights as collateral security. As Jellicoe had the reputation of being a rich man, Cort had not the slightest suspicion of the source from which he obtained the advances made by him to the firm, nor has any connivance whatever on the part of Cort been suggested. At the same time it must be admitted that the connexion was not free from suspicion, and, to say the least, it was a singularly unfortunate one. It was fo

ng to His Majesty is in great danger of being lost if some more speedy means be not taken for the recovery than by the ordinary process of the Court." Extraordinary measures were therefore adopted. The assignments of Cort's patents, which had been made to Jellicoe in consideration of his advances, were taken possession of; but Samuel Jellicoe, the son of the defaulter, singular to say, was put in possession of the properties at Fontley and Gosport, and continued to enjoy them, to Cort's exclusion, for a period of fourteen years. It does not however appear that any patent right was ever levied by the assignees, and the result of the proceeding was that the whole benefit of Cort's inventions was thus made over to the ironmasters and to the public. Had the estate been properly handled, and the patent rights due unde

Fearing to tackle the popular statesman himself, they inverted the ordinary tactics of an opposition, and fell foul of Dundas, Lord Melville, then Treasurer of the Navy, who had successfully carried the country through the great naval war with revolutionary France. They scrupled not to tax him with gross peculation, and exhibited articles of impeachment against him, which became the subject of elaborate investigation, the result of which is matter of history. In those articles, no reference whatever was made to Lord Melville's supposed complicity with Jellicoe; nor, on the trial that followed, was any reference made to the defalcations of that official. But when Mr. Whitbread,

ussions availed nothing. On the death of Jellicoe, he left his iron works, feeling himself a ruined man. He made many appeals to the Government of the day for restoral of his patents, and offered to find security for payment of the debt due by his firm to the Crown, but in vain. In 1794, an appeal was made to Mr. Pitt by a number of influential members of Parliament, on behalf of the inventor

they never paid him a shilling of royalty. These men of gigantic fortunes have owed much-we might almost say everything-to the ruined projector of "the little mill at Fontley." Their wealth has enriched many families of the older aristocracy, and has been the foundation of

ack, formed his entire fortune. It took him a fortnight to make the journey, in consequence of the badness of the roads. Arrived in London, he sold his pony for fifteen pounds, and the money kept him until he succeeded in finding employment. He was so fortunate as to be taken upon trial by a Mr. Bicklewith, who kept an ironmonger's shop in York Yard, Upper Thames Street; and his first duty there was to clean out the office, put the stools and desks in order for the other clerks, run errands, and act as porter when occasion required. Young Crawshay was very attentive, industrious, and shrewd; and became known in the office as "The Yorkshire Boy." Chiefly because of his "cuteness," his master appointed him to the department of selling flat irons. The London washerwomen of that day were very sharp and not very honest, and it used to be said of them

ill district, of difficult access, and the manufacture being still in a very imperfect state, the progress made was for some time very slow. Land containing coal and iron was deemed of very little value, as maybe inferred from the fact that in the year 1765, Mr. Anthony Bacon, a man of much foresight, took a lease from Lord Talbot, for 99 years, of the minerals under forty square miles of country surrounding the then insignif

iron weekly, and it was of a very inferior character,[11]-the means not having yet been devised at Cyfartha for malleableizing the pit-coal cast-iron with economy or good effect. Yet Crawshay found a ready market for all the iron he could make, and he is said to have counted the gains of the forge-hammer close by his house at the rate of a penny a stroke. In course of time he found it necessary to erect new furnaces, and, having adopted the processes invented by

and was quoted as the highest authority in all questions relating to the trade. Mr. George Crawshay, recently describing the founder of the family at a social meeting at Newcastle, said,-"In these days a name like ours is lost in the infinity of great manufacturing firms which exist through out the land; but in those early times the man who opened out the iron district of Wales stood upon an eminence seen by all the world. It is preserved in the traditions of the family that when the 'Iron King' used to drive from home in his coach-and-four into Wales, all the country turned out to see him, and quite a commotion took place when he passed through Bristol on his way to the works. My great grandfather was succeeded b

We have by his invention, not only ceased to be dependent upon other nations for our supply of iron for tools, implements, and arms, but we have become the greatest exporters of iron, producing more than all other European countries combined.

the committee-that they were overborne by the audacity of Mr. Samuel Homfray, one of the great Welsh ironmasters, whose statements were altogether at variance with known facts-and that it was under his influence that Mr. Gilbert drew up the fallacious report of the committee. The illustrious James Watt, writing to Dr. Black in 1784, as to the iron produced by Cort's process, said, "Though I cannot perfectly agree with you as to its goodness, yet there is much ingenuity in the idea of forming the bars in that manner, which is the only part of his process which has any pretensions to novelty….
