While the treatment of some of the subjects included is necessarily brief, we have striven to anticipate the daily wants of the user and to give him, in the manner best suited to his needs, the informa¬ tion he desires. The breaker boy, the driver, the helper will find many useful hints to help him in his work and to assist him in securing advance¬ ment. From a vast number of reference tables and formulas only the best have been selected and incorporated, and these have been thoroughly explained. This feature in itself should result in a great saving of time and in preventing the selection of the wrong table or formula. The subjects of surveying, use and care of wire ropes in connection with hoisting and haulage, electric¬ ity, opening of mines, timbering, methods of working, and of ventilation have received special attention. Safety appliances, which include elec¬ tric signaling devices and safety lamps, are treated in detail, as is also the care and use of m IV PREFACE explosives.
