within 2 miles of shore. 
(c) A comparison of the first two columns shows the possibility of there 
being a greater number of species in the western part of the lake than in the 
eastern end. There is a possibility also that quantitative differences exist in 
these regions as well as qualitative. | 
The results of this study serve to emphasize anew the importance of the 
plankton fauna of our inland waters, and the necessity for a thorough quantita- 
tive, qualitative and distributional investigation of these organisms, including 
particularly their relations to the production, distribution and movements of 
fish.
