“10. Jonathan Creek is a tributary of the Muskingum, rising 
in Thorn township, Perry county, near sa eastern end o 
Licking Summit reservoir. e valle which it runs af- 
forded an important outlet to the Aasatad region. It is about 
a mile wide, and kame-like ridges of gravel, from fifteen to 
ee feet in ne extend for a mile or more down the val- 
another creek, whose headwaters are near Somerset, and out: 
side of the glaciated region where terraces and all other signs 
of drift are altogether absent. 
The Hocking River issues from the glaciated area at 
Lancaster. I did not examine the present valley of the stream 
outlet. Gravel is specially abundant where small tributaries 
have come in from the glaciated region just to the north. At 
the mouth of Raccoon Creek, near Berne station, gravel depos- 
its rise Se hills sixty feet. 
12. The Scioto Fiver occupies a much broader valley than 
any of the preceding, and is much the largest stream issuing 
from the glaciated region before reaching the Ohio. The gla- 
cial boundary crosses it a few miles above Chillicothe, and the 
terraces from Circleville down are worthy of close study ; but 1 
must confine myself to the gravel deposits near the glacial 
boundary. In the southern part of section 29, Green township, 
three miles east of the river, there are enormous kames risin 
(according to barometer) 150 feet above the general level, ba: 
running in a north and south direction.~ The material of this 
kame is rather fine, and consists principally of limestone peb- 
bles. Above this point the plain is very broad and extensive ; 
below this, the valley contracts toa width not over two miles, 
and is bounded upon either side by pre pon sandstone hills, 
ee rise 500 or 600 feet above the valley. On goin 
these kames to the river, westward, chive broad parallel ridges 
are encountered, each one in order ‘toward the river extending 
sore south. The second one of these rises abruptly to a
