Hubbard. 



During the last two summers, while gathering data for a 

 preliminary report on the physiography of the state, the author 

 has found, in several localities of eastern Ohio, evidence of 

 valley glaciers. It is undertaken in this paper to describe some 

 of the long, narrow lakes that were associated with the with- 

 drawal of these valley dependencies of the Wisconsin ice sheet

from several of the rock valleys of northeastern Ohio. As in 

 New York state, only the hilly region has been favorable to 

 the development of such lakes ; and also as in New York, the 

 hilly part contains several rather interesting finger lake basins. 

 But differing from those in the eastern state, our Ohio finger 

 lakes have usually not persisted to the present, nor were they 

 quite so genetically inter-related. 



The following statement is a preliminary report on the lake 

 beds, a report of progress, stating some results of a rapid investi- 

 gation of the Ohio finger lakes. It presents positive evidence 

 of the occurrence of four such lake beds. If our topographic
