the bay; but at the time i' Avas seen but little water ran 

 out; and in the lower part of its course it consisted of stretches 

 of water connected by narrow rivalets. Some of the pools were 

 of considerable depth. The bottom is commonly muddy, but oc- 

 casional beds of sand occur. -There was no vegetation. 



WOOD SLOUGH. 



Wood Slough is also a narrow channel extending obliquely 

 across the lower part of the Illinois bottom-land from river to 

 bay. It formerly entered the bay opposite the north end of 

 Quincy, but the building of an embankment for a railroad bridge 

 cut it off from this outlet so that it now turns west at its lower 

 end and, running along the embankment, empties into the river 

 again. Throughout its course it is very nearly parallel with the west 

 shore of the island, in some cases being only a few rods away from 

 the river. The river enters it four miles northwest of Quincy. 

 and a mile and a half below this it breaks through the bank to 

 the river again, so that at low water its lower part may not be 

 continuous with the rest. It is perhaps three and a half miles 

 long, — a narrow, muddy ditch of shallow water, completely devoid 

 of vegetation, and containing such animals only as are so unfor- 

 tunate as to be entrapped in it by the subsiding spring floo^. 



CLAUS LAKE. 



This lake is a small temporary pool in the bottom-land about 

 one fourth mile east of the north division of Wood Slough. It is 

 very shallow, — at no place up to the mens' waists; has the usaal 

 muddy bottom; and lacks vegetation. 



DEAD man's slough. 



Dead Man's Slough is a name applied by the fishing crew to a 

 shallow, muddy pool in the woods about a quarter of a mile from 

 the river above the north end of Wood Slough. 



MOSS lake. 



Moss Lake, on the southern part of Long Island, the largest of 

 the LaGrange group, is very similar to the last two in general 

 character, being an isolated pond in the woods. It is, however, 

 much deeper than they, and its water is cooler and clearer. It is 

 surrounded by a growth of hickory, elm, sycamore, and grape.^ Its 

 length is less than a fourth of a mile, and its width froni 150 to 

 200 feet. No aquatic vegetation was growing in it when it was 

 seined in August. 



LILY LAKE. 



Lily Lake is one of a group of three lakes which lie between the 

 lower end of Wood Slough and Quincy Bay. They have a common 

 outlet during the fore part of the summer through Wood Slough.
