Excerpt from Mining and Mining Machinery: Explaining the Methods of Obtaining Minerals, Precious Stones, &C., , In All Parts of the World In the following pages the author has endeavoured to give the general reader an idea of how mining is carried on. He wishes it to be understood that the book is not designed for students in the ordinary acceptance of the term, though possibly those who are commencing the study of mining may find a perusal of its pages of assistance as an introduction to the standard mining text books. The author's idea in preparing the book has been, to give those who are interested in mining, those who may have shares in mining, and who may be surprised at the ups and downs of the values of those shares, some idea of the great uncertainty attending mining operations. The author wishes to acknowledge his indebtedness to the Editors of The Engineering and Mining Journal, and Coal Age, of New York, Mines and Minerals of Scranton, Pa., South African Engineering, of London, Iron and Coal Trades Review, also to Mr. H. Bulmann, The Ingersoll Rand Company, The Hardy Patent Pick Company, The Jeffrey Manufacturing Company, The Sullivan Machinery Company, Messrs. Ackroyd and Best, and The C.E.A.G. Electric Lamp Company, for the illustrations that are made use of in the book. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
