Abstract

This paper presents bacteriological analyses of the deposits of Lake Mendota, a fresh-water lake in Wisconsin. Samples were taken from two different stations in both winter and summer from the surface of the deposit and from the underlying marl. A varied flora was found, including most of the groups of soil microorganisms. The nitrifying and cellulose decomposing bacteria were detected only in a few instances in the surface muds.
