Thorn Creek, which leaves the lake on the south, passing into Blue River, 
then into Eel River, and so into the Wabash. 
The outlet from Shriner Lake to Round Lake is a narrow artificial 
channel. The connection between Cedar Lake and Round Lake is formed 
by a marsh, grown up with cat-tail flag (Typha latifolia), button-bush 
(Cephalanthus occidentalis), swamp loosestrife (Decodon verticillatus), and 
a variety of other marsh plants, with occasional stretches of open water. 
But little time was spent about Cedar Lake. Its shores are covered 
with underbrush, and the bottom of the lake is so soft and, near the 
shore, so encumbered with tree trunks and branches that collecting is very 
difficult. A number of dragonflies were taken, but nothing was found 
here that was not observed at Round and Shriner. 
Shriner Lake is one and one-quarter miles long, east and west, and one- 
quarter of a mile wide.* A small stream, which is dry most of the year, 
enters the lake at its southwestern part; but springs are almost the entire 
source of water supply. The temperature for some points at the bottom 
of the lake is as low as 50 degrees. The shores are sandy, and, with the 
exception of a portion of the northern part, solid and firm. Generally the 
bottom slopes rapidly from the shore line of deep water. The greatest 
depth is over seventy feet. Back from the water line the shores rise in 
low bluffs, covered with oak, maple and beech timber. A few sycamores 
and cottonwoods grow near the water’s edge. About the western and 
northwestern parts of the lake the land has been cleared, and is now 
under cultivation. 
The flora of the region is rich. Among the more conspicuous plants 
the following may be mentioned: Water-lily (Vymphea odorata), spatter- 
dock (Nuphar advena), water-shield (Brassenia  peltata), bladderwort 
(Utricularia vulgaris), stiff white water-crowfoot (Bidens Beckii), water- 
weed (Llodea Canadensis), cat-tail flag (Typha latifolia), arrow-head (Sagit- 
taria), pickerel-weed (Pontederia), several species of pondweeds (Pota- 
mogeton), pipewort (Lriocaulon  septangulare), Qdulichium (Dulichium 
arundinaceum), several species of spike-rush (Eleocharis), several species 
of bullrushes (among them WS. atrovirens, S. lineatus, S. Americanus, and SS. 
lacustris), beak rush (Rhynchospora glomerata), bog rush (Juncus Canadensis 
var. longicaudatus), and several species of Cyperus. Thistles, goldenrods, 
asters, mints, knotweeds (Polygonum), and blue flag (Jris), with a variety
