Walnut Creek and Lockbourne. The reservoir soon proved inade- 
quate for the canal, and in 1834 about 700 acres (280 hectars) 
were added, forming its present area. Its watershed embraces 
about go square miles (2331 hectars), which cannot be greatly 
enlarged. The lake then known as Licking Reservoir has, however, 
never stored a sufficient water supply and is not used for transpor- 
tation purposes now. A large number of trees then standing soon 
died and fell into the water, where they remained beneath the 
surface. The majority of the trees were gradually cut away with

their stumps exposed during low water. Only recently (the winter 
of 1908) the greater part of these stumps has been removed. 
Near the northern bank of the lake, about one-half mile (0.16 
km.) southeast of Buckeye Lake station, is the bog island, approxi- 
mately one-tenth the dimensions of the lake (fig. 3). In position 
it is more or less sheltered by hills and a woodlot. The peat 
mass rises and falls with the changing water level of the lake, and 
supports a vigorous growth of trees, low bushes, sphagnum mosses, 
and cranberrries. Borings were made at various points on the 
island with a sampling tool devised by Davis (2), to determine 
the depth and the character of the peat. About 50 soundings 
were made, which indicate an average depth of peat of 30~35 feet 
(9-10 m.) along the southern shore of the bog island, and 11 feet
