Believing that the study of Agricultural Engineering should fill an important place in the training of the young man who would make farming the object of his life's work, the author has attempted to furnish in this volume an aid in supplying this part of his training. The application of agricultural engineering methods to agriculture should not only raise the efficiency of the farm worker but should also provide for hlm a more comfortable and healthful home. This volume has been written primarily as a text for secondary schools of agriculture, and for colleges where only a generaf course can be offered.
Claim is not made for much new material concerning the subjects discussed; but rather an attempt has ·been made to place under one cover a general discussion of agricultural engineering subjects which hitherto could not be secured except in several volumes and hence impractical for text-book purposes.

INSTRUCTION pertaining to Farm Machinery and Farm Motors has been quite recently added to the agricultural course in the majority of the agricultural colleges in the United States. Although the need and importance of such a study was self-evident, it was a new field, one in which the knowledge pertaining to the subject had not been prepared and systematized for instructional purposes. The latest book on the subject of Farm Machinery was written by J. J. Thomas in 1869, before the general introduction of labor-saving machinery for farm work. Many books have been written on the various motors used for agricultural purposes, but it is not believed that an attempt has been made to place in one volume a discussion of them all. The authors have felt the need of a text for instructional purposes, and it is this need that has prompted them to prepare this book. It is a revision of the lecture notes used before their classes for several years. These notes were prepared from a careful study of all the available literature on the subject, and from observation made in the field of the machines at work and in the factories where they are made.
