of grasses and smaller sedges cover the shores. In adjoining woodlands 
I have found two species of orchids, the nodding pogonia (P. triantho- 
phora) and the coral-root (Corallorhiza odontorhiza). 
Round Lake is seven-eighths of a mile long and one-half of a mile 
wide. The water supply is derived from Cedar and Shriner lakes. Round 
Lake is shallower and warmer than Shriner and the water is less clear. 
Excepting small stretches of sandy beach along the northeastern and 
southern sides, the shores of the lake are soft and miry. The dredging of 
Thorn Creek has lowered the lake until at several places at a distance from 
shore the potamogetons reach the surface of the water. Lowering the 
lake five feet more will fill it with sand bars or even reduce it to a num- 
ber of ponds. An extensive tract near the head of Thorn Creek, which 
five year's ago was a Swamp, is now under cultivation. Among the farmers 
of the neighborhood the practice is common of planting artichoke among 
the spatter-dock where the lowering of the lake has exposed the land. In 
the fall this is turned over to hogs and their persistent rooting in the soft 
earth pulverizes and dries the soil most effectually. 
The vegetation about Round is ranker even than about Shriner 
Lake, and spatter-dock (Nuphar), which is rather rare there, almost sur- 
rounds this lake. In September, 1897, my friend, Mr. C. C. Deam, of Bluff- 
ton, Indiana, found the reversed bladderwort (Utricularia resupinata) 
growing along the western shore. Greater bladderwort (U. vulgaris) is 
abundant, and with potamogetons, eel grass (Vallisneria), hormwort (Cera- 
tophyllun) water-milfoil (Myriophyllum), and stiff white water-crowfoot 
completely clothes the bottom of the shallower parts of the lake. 
Not only is the vegetation more Juxuriant about Round Lake than 
about Shriner, but the former lake seems biologically richer in every way. 
Shriner is a beautiful, deep, clear, blue reservoir of spring water, while 
Round Lake is a warm, shallow basin, surrounded by marshes, and con- 
taining the overflow of two lakes, and the drainage of neighboring woods 
and fields. Mi. Kirsch has recorded twenty-one species of fish for Shriner 
_Lake and twenty-five species for Round Lake. I have not observed any 
“crawfish at Shriner Lake, but about the’ shores of Round Lake the bur- 
rows and chimneys of Cambarus diogenes are common. While the two 
lakes have each furnished about the same number of species of dragon- 
flies, these insects are usually much more numerous about Round than 
about Shriner.
