the direction of Prof. Herrick, the writer has endeavored to make the 
work as complete as possible, and it is hoped that the following pages

conglomerates I and II were exposed, when it would be impossible to 
misconstrue the relations. As has been stated, the object of the sur-

Waverly in Central and Northern Ohio. With that end in view, sec-

southern part of Ashland County to Cuyahoga Falls, Summit County. 
Over considerable areas it was impossible to trace the transition owing 
to the lack of high vertical sections, but most of the main facts illus- 
trating the sequence were discovered. 
In giving the results, we desire to acknowledge indebtedness to 
Prof. Pike of Garretsville, Portage County, and Mr. J. E. Woodland 
of Wooster, for valuable information respecting localities. Before giv-
