proposal is made that " steel " be the generic name for all varieties of usefully malleable iron with less than 2.2 per cent. of carbon. This term would then include wrought iron, puddled steel, blister steel, cemented bar, single-and double-shear steel, ingot iron, soft steel, mild steel, C steel, and alloy steels. The iron of commerce would then be divided ; that which is usefully malleable being kno'wn as " steel," and what is not usefully malleable known as " cast iron."
