Excerpt from The Copper Mines of the World The present work is the outgrowth of the need felt by the author of a book presenting the kwn facts concerning the copper deposits of the world. It is confessedly in part a compilation; for, while the writer has seen almost all the big mines of the United States, Canada, and Mexico, which furnish two-thirds of the world's output, he has culled freely from the detailed studies of others for descriptions of them as well as of foreign districts. Much interesting matter concerning the lesser and ecomically unimportant deposits of Europe has been omitted in the attempt to present more than a scrap-book collection of mine descrip tions, and to keep the matter written within a reasonable number of pages. Many important occurrences receive but Short accounts, and many deposits of present importance are fully described. The first circumstance is due to a lack of reliable information; the second, either to a belief in the future importance of the deposit or to a de sire to prevent the waste of money on worthless properties. No attempt is made to present the facts concerning the financial as peet of properties. For this purpose I recommend the Copper Hand book, Of Horace J. Stevens, which covers that field thoroughly, and Should be owned by every one interested in copper-mining companies. The reduction of copper ores is well and authoritatively treated in Peters' Modern Copper Smelting and the reader is referred to that work for such information.
