EXPLANATION OF MAP. 



The course of the old Kanawha System frorn St. Albans, W. Va., to Wav- 

 erly, Ohio, is indicated by dotted lines representing the breadth of its channel. 

 The northward discharge from the Symmes Creek drainage basin is similarly 

 shown. 



The position of cols is indicated by a cross bar. In cases where some 

 doubt is felt concerning the col a query mark (?) is affixed. 



The vagueness of the glacial boundary in this region is such as to render it 

 difficult to determine with accuracy. It should be noted that the boundary 

 here represented lies a few miles outside the lines which Prof. G. F. Wright 

 has published. The departure however seldom reaches lo miles.
