The habitat 
The field work which forms the basis of the present paper was 
carried on at Buckeye Lake, Ohio. The geological record of the 
region is for interest second to few places in Ohio. The strata 
furnish an almost unbroken narrative from the Silurian up to the 
Tertiary. It is a rare thing to find peat bogs in Ohio south of 
latitude 40°, and this circumstance makes the locality as the 
southernmost limit of existing peat formations still more interest-

Buckeye Lake is situated in Licking, Fairfield, and Perry 
counties, about 26 miles (41 km.) east of Columbus, and is at an 
- elevation of 1 50 feet (45 m.) above that of the University campus. 
The area and location are shown on the Thornville sheet of the 
US. Geological Survey (fig. 1). The lake, like many others, is 
one characteristic of the highlands of watersheds throughout 
Ohio and adjoining states. The heath bogs in Wyandot County, 
the extensive bogs in Huron County, possibly among the largest
