The present paper compares the condition of the bottom fauna of Peoria Lake as found in July-September, 1922, with that of the summer of 1920, which was probably very close to its point of low condition following the mortality of 1917-1918, just referred to; with the result, in general, of indicating an essentially slight though measurable improvement in the two years.
