Excerpt from The Production of Iron and Steel in Its Economic and Social Relations, Vol. 1 In closing this brief statement of the remarkable specimens of cast steel in the Exposition, the products of the Bochum Company (prussia) Should not be overlooked. An enormous cast-steel bell, weighing pounds, remarkable for the admirable proportion which existed between its size and its tone, was not, however, more wonderful than the cast-steel railway wheels made in sets of ten or a dozen, united by a thin shaft of metal running through the centres, thus eu abling one sinking head to answer for the whole quantity, and securing greater density and soundness in the metal. These wheels, when cut apart and turned up, were beautifully sound and clean, and gave evidence of ability to cast steel with as much facility as ordinary cast iron. Another evidence of this was to be found in a locomotive cylinder, bored and of such finish and soundness as not merely to excite general admiration, but, induced the belief that possibly it was cast iron which had been deprived of its carbon by being annealed in a bath of oxide of iron, or some other decarbonizing material. In the Swiss department, machine-cut steel files were exhibited fully equal to any cut by hand; and this result is said to be due to the grinding of the blanks across the face instead of lengthwise, a point which may have great value to our own makers of files.
