THE successful education of the man in the shop is a question of vital importance. The difficulties under which he toils in his struggle for advancement, and his daily labor, render impossible the usual means of education, and prevent the attending of a resident technical school. Probably the most successful substitute for such a school is the correspondence method of instruction. Thousands of mechanics are improving their conditions by devoting a half hour each day in systematic study under the direction of men who have had long experience in teaching, and in practical shop work. There are, however, many who cannot afford the time and expense necessary for even a correspondence school course. For such the Cyclopedia of Modern Shop Practice is prepared.

This Cyclopedia is compiled from the most practical and most valuable Instruction Papers of the American School of Correspondence. These Instruction Papers have been prepared especially for home study and are intended primarily for such work. As their extended use in the American School of Correspondence has proved them to be of great practical value, and a successful means of instruction, they form a reliable treatise on the subject of shop practice.

The correspondence student needs a thoroughly technical work free from superfluous theory; in like manner the reader of the Cyclopedia must have the necessary theories carefully explained, and the results of practical experience clearly pointed out. By giving the best material on shop practice to the busy man in the shop, the editors hope that he will achieve the success that results from a combined knowledge of theory and practice.
