oreenstone, etc., are the most usual kinds of rock, though many fragments 
of limestone and shale prevail. From the kind and character of the rock 
composing these kames, I take the material to be re-wrought material of 
the glacial drift. 
A few of the ordinary fossils were: Spirifer mucronatus, Avicula emacer- 
ata (2), Rhynchonella capax, and many cyathophylloid and silicious favosi- 
toid corals. The native Niagara and Waterlime Groups also contribute 
a number of specimens. In most cases the fossils, like the other pebbles, 
are very much worn, and thereby rendered almost unrecognizable. 
Below is a section of one of those isolated kames spoken of, known as 
“Bunker Hill,” situated about a mile and a half south-west from Green- 
ville, near the Pittsburg, Cincinnati and St. Louis Railroad :

In this instance there were no bowlders at all, and three-fourths of the 
pebbles consisted of limestone and blue shale. The layers, too, were ex- 
ceedingly well stratified, and largely present the interlocking appearance. 
A dozen different sections might be given, but the two selected here 
present the greatest variance of any two yet observed, and may be con- 
sidered as combining the characteristics of all.
