If, perchance, we die abroad, we may return in a casket of steel. Preceding, accompanying, and permitting this great increase in the uses of iron and steel, there has been development in its manufacture. The multitude of uses means that there must be many grades and kinds of iron and steel, and that the manufacturer must have perfect control of the product turned out in the various stages of its manufacture. This control he has. It is therefore natural to expect that the blast furnace should be among the most thoroughly organized and most highly developed pieces of mechanism yet devised. It is certainly the most fearful of all man's creations, and considering the character of the process which goes on within it and its unapproachable heat, it is under a wonderful degree of control. At the present time, the best blast furnaces are a hundred feet high, consist of a great iron stack lined with some nonfusible material, and when in operation are filled from top to bottom with roaring fire. Into their fiery throats are fed alternately small carloads of coke and ore and limestone, and from the bottom there flows away at inter-k vals two molten streams--one the precious iron upon which our civilization rests; the other the Two Modern Blast Furnaces With Row Of Stoves Between useless slag, to be got rid of in the cheapest possible way. The unassisted fuel could not furnish enough heat to extract the iron from the ore without the presence of the limestone flux, which greatly reduces the melting temperature and helps get rid of impurities in the following manner. All ore contains a certain amount of waste more
