places, and not more than three of the outcrops could be other 

 than outliers. 



A few of these outcrops may be described briefly. About 

 7 miles northwest of Zanesville on the north side of the Licking 

 River and about 11 miles north of the Fultonham outcrops 

 described by Morse, two outcrops were found well exposed 

 in ravines about 3^ mile apart. The limestone is bluish gray, 

 fine grained, compact, without prominent bedding planes and 

 3 to 7 feet in thickness. No fossils were found, and it appears 

 to be the lower division of the Maxville described by Morse. 

 Apparently it rests conformably upon the Logan shale, but is 

 overlain unconformably by Coal Measure sandstone. 



It was again found in bed north of the Walhonding River, 

 23^ miles north of Walhonding Village and 2 miles south of 

 the village of Tiverton Center in northwestern Coshocton 

 County. There six feet of the limestone is well exposed in a 

 deep ravine, contains considerable iron, weathers to the color 

 of yellow clay — indeed almost to the yellow of ochre. The 

 top and bottom weather to a brown. It looks so very like a 

 compact yellow clay that one's first impression of it is that 

 it really is a bed of clay. Digging into the yellow mass 4 to 6 

 inches dispels the illusion by finding the familiar fine grained 

 light gray limestone. The upper surface as seen in the ravine 

 side is uneven and is overlain by 2 feet of light green mud 

 mingled with flinty cobbles of limestone. The mud bed 

 appears to be the residual material of the decomposing limestone. 



Resting directly upon the mud bed is the pebbly Coal 

 Measure rock. This peculiar green mud carrying angular 

 cobble stones, and the underlying limestone weathering to an 

 ochre color is very like exposures found by Morse far to the 

 southward. 



Eight miles southeast of the above exposure is the town of 

 Warsaw. Several outcrops occur at 1 to 4 miles north and 

 east of this place which range from 2 to 9 feet in thickness. 

 Two miles east of Warsaw an outcrop presents the ochre 

 weathering phase in marked degree. Four miles east of Warsaw 

 and () miles northwest of Coshocton in the high bluff over- 

 looking the junction of Killbuck Creek and Walhonding River 

 occurs the most easterly outcrop found. Three feet of hard 

 gray limestone in several layers weathering brown are exposed 

 and with neither top nor bottom seen.
