Excerpt from Safety and Efficiency in Mine Tunneling In most of the published accounts of tunnel work the writers do not attempt to criticize the methods they are describing. The arti cles usually present accurate descriptions of equipment and of vari ous phases of working Operations, with occasional figures showing the cost of the work; rarely do they include a discussion of the means for preserving the health and life of the employees or data bearing on the choice and efficiency of equipment, or an analysis of methods and costs. As a result, the reader who endeavors to draw conclusions is dependent wholly on his own resources. In this bulletin, on the contrary, the making of such analyses will be a primary considera tion, but as the purpose of the bulletin is to give an impartial dis interested report, the criticisms made are intended to be constructive rather than destructive. For that reason emphasis is placed on safe, efficient, and economical methods and on good points of equipment, whereas bad practice and obsolete machinery are ignored, except, perhaps, as examples of what was inadvisable or as having some bearing historically. Thus the authors hope to set forth a guide for future work rather than an unillumined record of past or present achievement.
