Excerpt from Applied Science, Vol. 22: Incorporated With Transactions of the University of Toronto Engineering Society; November, '08 to April, '09 The profession of mining engineering embodies very much more than any one man's mind could possibly encompass. And there is a limitless number of subdivisions or combinations of subdivisions for the specialist in which to bury himself. In general, mining engineers are divide-d into two main classes. Viz., Mining Engineers and Metallurgical Engineers. Under this classification in its closest sense, the mining engineer has to do with the getting of ore to the point where it lies in a broken state at the surface, and the metallurgical engineer carries on the work from this point until the metals are finally extracted from the ore. But as a general rule the metallurgical engineer's work is confined to smelting operations, while the processes of mechanical concentration of ores, and even the leaching and lixi viation processes are in the hands of the mining engineer in charge of the other mining work. The reason of this is to be found in the fact that as a rule the mechanical concentration and lixivia tion of ores is carried on at the mines under the one management: while smelting is generally done at some central point at a distance from the mining operations. The department of smelting I must leave out of consideration. And trust some other graduate will take up this very important branc'h.
