iron and steel may be obtained. One of the most valuable forms of the metal is described by Mr. Bessemer as "semi-steel," being in hardness about midway between ordinary cast-steel and soft malleable iron. The Bessemer processes are now in full operation in England as well as abroad, both for converting crude into malleable iron, and for producing steel; and the results are expected to prove of the greatest practical utility in all cases where iron and steel are extensively employed. Yet, like every other invention, this of Mr. Bessemer had long been dreamt of, if not really made. We are informed in Warner's Tour through the Northern. Counties of England, published at Bath in 1801, that a Mr. Reed of Whitehaven had succeeded at that early period in making steel direct from the ore; and Mr. Mushet clearly alludes to the process in his "Papers on Iron and Steel." Nevertheless, Mr. Bessemer is entitled to the merit of working out the idea, and bringing the process to perfection, by his great skill and indomitable perseverance. In the Heath process, carburet of manganese is employed to aid the conversion of iron into steel, while it also confers on the metal the property of welding and working more soundly under the hammer--a fact discovered by Mr. Heath while residing in India. Mr. Mushet's process is of a similar character. Another inventor, Major Uchatius, an Austrian engineer, granulates crude iron while in a molten state by pouring it into water, and then subjecting it to the process of conversion. Some of the manufacturers still affect secrecy in their operations; but as one of the Sanderson firm--famous for the excellence of their steel--remarked to a visitor when showing him over their works, "the great secret is to have the courage to be honest--a spirit to purchase the best material, and the means and disposition to do justice to it in the manufacture." It remains to be added, that much of the success of the Sheffield manufactures is attributable to the practical skill of the workmen, who have profited by the accumulated experience treasured up by their class through many generations. The results of the innumerable experiments conducted before their eyes have issued in a most valuable though unwritten code of practice, the details of which are known only to themselves. They are also a most laborious class; and Le Play says of them, when alluding to the fact of a single workman superintending the ope
