Excerpt from International Library of Technology: A Series of Textbooks for Persons Engaged in the Engineering Professions and Trades or for Those Who Desire Information Concerning Them, Fully Illustrated and Containing Numerous Practical Examples and Their Solutions The present is the first Of a series of three volumes devoted to mining engineering and treats on mine gases, mine venti lation, economic geology of coal, prospecting for coal, loca tion of Openings, shafts, slopes, drifts, methods of working coal mines, and electric mining machinery. Mine Ventila tion, Part 1, treats on the theory of mine ventilation, and it is believed presents this somewhat difficult subject in clearer and simpler language than has heretofore been successfully attempted. The papers relating to electric mining explain the workings, advantages, and disadvantages Of machinery operated by electricity that are used in mining operations; they treat on electrically driven hoisting, haulage, and coal cutting machinery, electric pumps and pumping, and signal ing and lighting by electricity. The method of numbering the pages, cuts, articles, etc. Is such that each subject or part, when the subject is divided into two or more parts, is complete in itself; hence, in order to make the index intelligible, it was necessary to give each subject or part a number. This number is placed at the top of each page, on the headline, opposite the page number; and to distinguish it from the page number it is preceded by the printer´s section mark Consequently, a refer ence such as 37, page 26, will be readily found by looking along the inside edges of the headlines until §37 is found, and then through §37 until page 26 is found.
