(2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from The Cost of Mining: An Exhibit of the Results of Important Mines Throughout the World Some six years ago a discussion started by Messrs T. A. Rick ard and W. R. Ingalls of the Engineering and Mining Journal on the Cost of Mining attracted considerable discussion from min ing engineers throughout the world, and I contributed some articles. It was natural to continue the investigation of the subject. In 1908, at the suggestion of Mr. Ingalls, I undertook to prepare some more extended articles for the same journal with a view of rationalizing the subject to show how the natural factors inevitably impose certain costs that sound engineering must recognize, and that to attempt economies unjustified by the conditions is the rankest extravagance. This book is the outgrowth of those articles and to a lesser extent of some lectures given at Harvard University and a large amount of discussion and correspondence. The subject is one that is inherently interesting to mining men and mining engineers and it seems possible that it may interest a somewhat wider field. Those who are interested in financial and economic developments can hardly escape some contact with the mining business.
