Edward B. Durham

[1][2] Durham received his MA in mining at the Columbia University in 1893, where he was classmate of Halbert Powers Gillette.

In 1901 back at Columbia University he started lecturing mining, and was eventually promoted to Professor.

[6] In 1918 he published one of his latest known articles on "Aerial tramways and cableways" in the Mining Engineers' Handbook.

The principle of flow sheets is of wide application; in business, it can be used to show the organization of the staff and to whom each is responsible; in manufacturing, the passage of the material through the works, from department to department, and even the steps in each department, can be shown; in milling or metallurgical operations, the passage of the material from process to process and the resulting products and their disposal can be shown; in power distribution, the heat generated by coal under the boilers can be followed in its change to mechanical power and its application to various machines.

The reviewer has not seen any book which surpasses it in the treatment of the subject, or in general arrangement, clearness and brevity of statement.
