PREFACE. YIITLE much has been written with regard to methods of mining ore and many excellent descriptions of the methods employed in the mines of the United States and abroad are to be found in the technical press, yet there is no work in which systematic and detailed descriptions of the various typical methods are to be found. he writer has therefore attempted to prepare a work on ore mining methods alone, which it is hoped may prove useful to both the student and the practical man in acquiring a knowledge of ore mining and in comparing methods. That the work may be of the most service, the descriptions have been made brief and many illustrations employed to supplement them. Illustrations taken from photographs of mine models have been extensively used and possess the advantage over diagrams in that by relief three dimensions are shown. Further, the application of each method has been specifically stated, together with the advantages and disadvantages of its use. The classification of methods followed is based upon size of deposit, rather than kind of mineral or metal and character of deposit, which seems the simplest and most logical method of treatment. The idea has been to describe only those methods which have proved successful not only in one locality but several, and not to consider proposed methods nor those in the experimental stage. In order to verify descriptions and to study methods more in detail the writer has visited the mines in which practically v all of the methods described arc cmplo-ed ho evepre, r - sonal inspection has been confined to the mines of the United States. The present volume, I-hich is the second edition, has been completely revised and much new material has been added. includi lg a chapter 011 development of mines.
