Excerpt from Handbook of Mining Details This book is a collection of articles that have appeared in the Engineering and Mining Journal during the last two or three years under the general head of "Details of Practical Mining," a department of the Journal that has been appreciated highly by its readers, many of whom have expressed the wish that a collection in book form be made, which has now been done. In the editing of this volume, the work has been chiefly in the selection of the material and its arrangement in chapters. Now and then it has been possible to excise some paragraphs as being unessential and occasionally the phraseology of some articles has been altered a little, the requirements of preparation for the original weekly publication not always having permitted leisurely consideration, but in the main the articles now presented in this book are as they were given in the pages of the Engineering and Mining Journal. However, it has been necessary in a few cases to reduce the size of the engravings. In making this collection the limitation of space necessitated the rejection of all material that did not pertain to the subjects selected for the chapters of the book, and even so it was necessary to dismiss some of the longer articles pertaining to them, which approached the character, of essays rather than being the description and discussion of details. Of course a wealth of contributions pertaining to the arts of ore dressing and metallurgy had to be rejected summarily. The compilation covers the publications in the Engineering and Mining Journal from Aug. 7, 1909, to July 1, 1912. If all of the material that appeared in this department of the Journal during that period of three years had been used it would have been necessary to make a book of several times the size of this. No claim is made that this book is a treatise, exhausting its subject, or any part of it. It is simply a handbook that is a more or less random collection of useful information, being just what passes through the pages of the Engineering and Mining Journal in the course of a few years. No special attempt to round out any subject has been made. Yet it will be found that some subjects are fully treated. With regard to the authority of what is to be found in these pages: The matter in the main is merely descriptive of what is done. Nevertheless, there is frequently the injection of opinion and advice. A great technical journal is directed by its editor and is shaped by its editorial staff, but it is essentially the product of its contributors. It is a co-operative institution and its pages are a symposium of the experiences and views of many professional men.
