Prof. E. A. Birge of the University of Wisconsin delivered the 
evening’s lecture on “An Inland Lake.” This lecture was illustrated 
by numerous lantern slides, showing the various forms of plant and 
animal life. Prof. Birge called especial attention to the difference in 
the abundance of life in the deep and shallow lakes. In shallow lakes, 
the water circulates much more freely and consequently there is a 
better distribution of the food materials. As a result of tliis fact, 
the shallower lakes support a much richer flora and fauna than do the 
deeper lakes of the same area. 
After a brief discussion, the meeting adjourned.
