From these records it will be seen that in the trough of the present 
Lake the prevailing direction of the glacial strie is 10° south of 
west, and the movement, as demonstrated by the observations made 
on Kelley’s Island and Put-in-Bay Island by myself, on West Sister 
Island and at Monclova by Mr. G. K. Gilbert, was from the east west- 
ward; and farther, that in the basin of the lake, but south-west of the 
Lake itself, the movement of the glacier was deflected southward until 
it became south-west. An interesting fact in this connection has been 
noticed by Mr. Gilbert, Mr. Winchell, and myself, that in this portion of 
the State a series of glacial marks, which have nearly a north and south 
bearing, are obliterated by the stronger, fresher, and more numerous 
srooves of which the bearing is nearly east and west. As I have shown 
elsewhere, the strie which cover the highlands and southern portions of 
the State were probably made by the continental gracier which existed 
during the period of greatest cold, and which had in Ohio a movement 
from the north toward the south or south-east; while the glacier which 
moved from the east westward in the lake basin was a local glacier of
