low, swampy land, and the country back of the swamp rises scarcely ten 

 feet above the lake. Farther south clay hills rise abruptly to an 

 elevation of 25 or 30 feet on both sides of the lake. The road run- 

 ning N. and S. east of the lake crosses five massive clay ridges 

 trending east and west within a mile, each rising 30 feet or more 

 above the lakes. There are three small islands and considerable shal- 

 low water in the southwestern part of the lake and the northern 



part is rather shallow, but fully one-half the area is covered with deep 

 water. The area drained into the lake is very narrow. I saw only one 

 inlet and that was short and small. Soundings, at intervals of about 80 

 feet, commencing on the east and following the axis of the lake, were as 

 follows: 24, 30, 30, 30, 30, 36, 42, 36, 36, 30, 24, 21, 18, 9, 6, 4, 4, 6, 6, 

 18, 21, 27, 33, 39, 45, 45, 45, 45, 39. 42, 60, 75, 81, 81, 84, 87, 90, 95, 96. 

 102, 102, 102, 105, 106, 106, 105, 105, 106, 105, 105, 105, 105, 96, 93, 93. 

 96, 99, 93, 81, 81, 81, 96, 99, 100, 99, 96, 99, 84, 75, 54, 42, 21, 27, §0, 

 42, 45, 45, 48, 45, 42, 36, 30, 27, 27, 27, 30, 30, 27, 27, 21, 15, 12, 12. 12.
