MONKOE COUNTY. 571 



ing of wide range that may serve as a datum line by which the geologist 

 may be guided. The dip of the strata, moreover, is not uniform, and, 

 consequently, is not a reliable guide until it is determined for a given 

 area ; and identification of the same seam of coal or other stratum at 

 two or more different points is a prerequisite to this determination of 

 dip. Hence in a large part of Monroe county the chief geological factors 

 are unknown terms. The supposition that the Evans coal, near Woods- 

 field, is the diminished equivalent of the Cumberland, or upper Barnes- 

 ville seam, appears the more probable one, and I have so given it on the 

 map of grouped sections. The other seams of coal are all, I think, ac- 

 curately brought into their proper relation to this, as shown on the map. 



FRANKLIN TOWNSHIP. 



This township lies on the western part of the county, and borders 

 Stock township, in Noble county. The land in the northern part of the 

 township is high, and divides the waters of Clear Creek — a branch of the 

 Little Muskingum River — from those of Wills Creek, which flow north- 

 ward. 



There is considerable limestone to be seen, and the soil is generally 

 productive. 



The Cumberland seam of coal, which extends so generally through 

 Noble county, and which is found in the hills at Carlisle, is found in 

 the neighborhood of Stafford. The larger developments seen were on 

 Road Fork, and they may be located just over the line, in Elk township. 

 Here the coal is four feet six inches thick.

This section is by oversight placed on the Noble County Map of 

 Grouped Sections XII., No. 33. 

 The creek at Okey's Mill, on Clear Fork, is reported to be forty-five 

 feet higher than Road Fork at the woolen mill, but the coal at both 

 places is covered by the same buff limestone. Further down Road Fork 

 the limestone is replaced by sandstone. There are changes in thickness 

 of the coal and in the lithological character of the associated strata, and
