There are, no doubt, manypersons still living who witnessed this combined converting andcasting apparatus in successful operation. Two Io-inches square ingots, made with this apparatus, weresent to the Dowlais Iron Works in Wales, and, without hammer-ing, were rolled into two flat-footed rails on the 6th of Septem-ber, 1856; that is, twenty-four days after the reading of the Cheltenham paper. They were rolled under the personalsuperintendence of Mr. Edward Williams, past president of theIron and Steel Institute. Two pieces of these rails are still keptat the Institute in a large glass case containing many otherexamples of the early working of my process in London and inSheffield. Before concluding this brief sketch of the earliest forms ofapparatus designed by me to facilitate or improve the process, The Iron and Steel Magazine

The Genesis of the Bessemer Process 495 I must revert to the difficulties inseparable from a fixed con-verter. In this form of apparatus much heat is dissipated bythe blowing which takes place during the running in of the metaland by the continuation of the blast after the metal is convertedand during the whole time of its discharge, which is a period ofuncertain length. There is also the difficulty of stopping theprocess if anything goes wrong with the blast engine, or if atuyere gives way. I searched diligently for a remedy for theseand other grave defects, which at that time appeared impossibleto remove, until the happy idea occurred to me of mountingthe converter on axis, so as to be able to keep the tuyeres abovethe metal until the charge of molten iron was run in, thus per-mitting the blowing of the whole charge to be commenced at oneand the same time, and admitting also of the cessation of blowingduring the discharge. This movement of the converter per-mitted a stoppage of the
