Chicago: The Reilly&Britton Company, 1911. 12mo.; 438 pp.; illustrated. Price, $2 net; postage 12 cents extra. The manual is addressed to those who wish to acquire a general yet practical knowledge of electricity without going so far as to take a complete course in electrical engineering. Only the simplest mathematics are used, and an effort is made to weld indissolubly fundamental principles and practical applications. The arrangement and treatment follow closely the course given in the evening classes of the Armour Institute of Technology, and the manual might be used as a text-book in High Schools and Manual Training Schools. A “Workers' Edition” is also issued, in flexible leather with protecting flap, inside pocket, and memoranda pages, at an advance of fifty cents in price over the regular edition. NATIONAL PROBLEMS AFFECTING THE LUMBER INDUSTRY. Tacoma, Washington: National Lumber Manufacturers' Association, 1911. 8vo.; 278 pp. Price $1. The annual conventions of the National Lumber Manufacturers' Association are always pro-ductive of many timely and important papers and addresses. The full proceedings of the ninth annual meeting are given by the volume in hand. There are opinions on Canadian reciprocity, able reviews of the business situation, and remarks on co-operation with the leaders of the conservation movement. The more important papers deal with such subjects as workmen's compensation, the principles of efficiency, currency reform, the Panama Canal in its relation to the lumber industry of the Pacific Coast, substitutes for wood, and the railroads and the lumber industry. Some opposition develops toward the Canadian reciprocity bill, and the measure is condemned as agreeing with no economic theory and as being particularly threatening to the prosperity of the lumber- industry of the United States.
