This manual is intended as a handbook of practical information for those who are called upon to operate a commercial or military electric plant without having had previous experience, while it will also be found to contain much of value to the engineer. It is written with the aid of notes actually obtained in handling the apparatus described, the chapter on incandescent lamps being especially notable, as this chapter has not been given in other works the prominence it deserves. In the selection and composition of the tables the author has endeavored to make them applicable to both American and foreign practice. The text is very fully illustrated, making the manual of exceptional value. The book is strongly commended to those desiring information on this subject.
