"The purpose of this bulletin is to acquaint farmers with the possibilities of developing the power of small streams by converting it into electrical energy and the uses to which such power can be put; to give information which will enable them to avoid unnecessary expenditures; to explain how to determine the power a stream will supply; and to indicate the sources from which to secure additional information in regard to the approximate cost of installing a plant suited to the power available. The details of design, installation, and operation of electrical equipment are not within the scope of this bulletin." -- p. ii

Revised edition. "This bulletin aims to furnish, in concise form, information that will be of practical help to the beginner in fruit growing. It deals with the widely grown temperate-climate fruits, such as the apple, pear, peach, and plum. Lists of desirable varieties of these fruits are given for the different parts of the country. Because of the number of fruits considered and the territory covered, cultural directions are necessarily brief, but they cover the most important general points." -- p. 2
