III.— SILVER LAKE. 
Silver Lake is one of tlie sources of the Little Sioux River. It is about 2 miles 
long, 1 mile wide, and very shallow, its depth seldom exceeding 6 feet. It contains 
very few game fishes. The larger game fishes are supposed to have been destroyed 
by the cold winters of a few years ago. On the northern side of the lake there is a 
small inlet with a very muddy bottom. We collected in the inlet and on the northern 
shore of the lake, where the bottom is sandy.
