Excerpt from Modern Tunneling In most of the published accounts of tunnel work, the writers usually do not attempt to criticise the methods they are de scribing. It is customary for such articles to contain accurate descriptions of equipment, various phases of working operations, and occasionally figures showing the cost of the work, but rarely do they include a discussion of the means for preserving the health and life'of the employees, or data bearing upon the choice and efficiency of equipment or an analysis of methods and costs. As a result, the reader in drawing conclusions is dependent wholly upon his own resources. In this volume, on the con trary, the making of such analyses will be a primary considera tion. It is desirable, nevertheless, in an impartial, disinterested book of this character to use constructive rather than destruc tive criticism. For that reason emphasis will be placed upon safe, efficient, and economical methods, and upon good points of equipment, While bad practice and obsolete machinery will be ignored except, perhaps, as examples of the inadvisable or as they have 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.
