What a Prominent Trade Paper Says About It.

A Handbook of Practical Value—The latest addition to the popular type of automobile handbook. “The How and Why of the Automobile,” by Fay L. Faurote, fulfills what its author has set himself to achieve, namely, to present a plain, easily understood description of the modern automobile. Assuming that his reader knows nothing about the subject, the author introduces the automobile in as simple and untechnical a manner as possible. The entire field is covered and covered so completely that the work can be recommended as a handbook for beginners or those with only a limited knowledge of this subject.—Automobile, April 18.
