Discover the architects and construction engineers of the animal world! From underground aardvark burrows to giant termite mounds, find out how animals build homes to keep them snug and safe from predators.

Many farmers do not realize that small streams may be used in generating electricity. Electrical equipment on the farm saves time and labor, but if it is to be a sound investment the cost of installation should not be greater than the benefits obtained can justify. 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 regarding 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.
