This work is a textbook of fresh-water life dealing with its forms, its conditions, its fitnesses, its associations, and its economic aspects. The ecologic side of fresh-water biology is emphasized. Due consideration is given to the educational, economic, sanitary, social, civic, and aesthetic aspects of the subject.
Limnology in America today is in its infancy. The value of its past achievements is just beginning to be appreciated. The benefits to come from a more intensive study of water life arc just beginning to be disclosed. That there is a widespread interest is already manifest in the large number of biological stations at which limnological work is being done.
We recommend this volume as a general introduction to all students and teachers of this subject.

James G. Needham (1868–1957) studied with John Henry Comstock at Cornell University from 1896 to 1898. From 1898 to 1907, he taught biology at Lake Forest University and then returned to Cornell as Assistant Professor of Limnology. In 1914, when Professor Comstock retired, Needham succeeded him as head of the Department of Entomology at Cornell, a position he held until his retirement in 1935. He published numerous scientific articles, educational papers, and textbooks; he also wrote poetry and philosophical writings.
