Synopsis

Excerpt from The Life of Inland Waters: An Elementary Text Book of Fresh-Water Biology for American Students

Our interests in water life are manifold. They are in part economic interests, for the water furnishes us food. They are in part aesthetic interests, for aquatic creatures are wonderful to see, and graceful and often very beautiful. They are in part educational interests, for in the water live the more primitive forms of life, the ones that best reveal the course Of organic evolu tion. They are in part sanitary interests; interests in pure water to drink, and in control of water-borne diseases, and of the aquatic organisms that disseminate diseases. They are in part social interests, for clean shores are the chosen places for water sports and for public and private recreation. They are in part civic interests, for the cultivation of water products for human food tends to increase our sustenance, and to diversify our industries. Surely these things justify an earnest effort to make some knowledge of water life available to any one who may desire it.

The present text is mainly made up of the lectures of the senior author. The illustrations, where not otherwise credited, are mainly the work of the junior author. Yet we have worked jointly on every page Of the book. We are indebted for helpful suggestions regarding the text to Professors E. M. Chamot, G. C. Embody, A. H. Wright, and to Dr. W. A. Clemens. Miss Olive Tuttle has given much help with the Copied figures.
