KANSAS PONDS. 
Puoto I. Smith Pond, a muddy pasture pond, frequented by cattle. | 
Here Buenoa was dominant in midsummer. 
Puoro. II. The large barren Brick Plant Pool, clay bottom and clay 
sides, no vegetation and few insects. 
Puorto. III. Rock Pool, a small temporary pool in which Notonecta 
undulata is dominant in early spring. They show as black specks upon 
the water in the photograph. 
Puoto. IV. Another view of Brick Plant Pool. 
PHoto. V. Bismarck Grove Pond, a permanent pond, suitable for 
winter quarters, but containing too little vegetation for many aquatic 
bugs. A few Belostoma were taken here. 
PuHoto. VI. A small pond at brick plant. This pond is overgrown 
with willows and cottonwoods. The bottom is thickly strewn with leaves 
and brush, ideal winter quarters for many bugs. 
Puoto. VII. Cattail Pool from the west end. This end is invaded by 
cattail. The water here is six inches to a foot deep. 
PuHoto. VIII. Cattail Pool from the south. The invading cattail on 
left. Here is the home of Hydrometra. Upon the floating Spirogyra 
are found Hydrometra, Microvelia borealis and Mesovelia mulsanti in 
great numbers. Gerris marginatus is here and there upon the surface. 
This temporary pool lies in a rock quarry and dries up in midsummer.
