to the Upper Freeport coal bed. Number 8 contains at some places 60 

 feet of red shale, the "Big lied" of counties farther south ; the red bed, 

 Number 6, is apparently the same with that seen in the eastern locali- 

 ties. No trace of the Elk Lick coal appears in any of the sections 

 and the Harlem is very uncertain, but the Anderson is persistent at about 

 70 feet below the Ames, sometimes resting almost directly on the Cam- 

 bridge limestone. The sandstone, Number 12, is at the place of the 

 Cowrun. The Brush Creek coal and limestone are very thin and the 

 former is reported very rarely.* 



Morgan county is south from Muskingum. In the central and north- 

 ern portion the Pittsburg coal bed is 142 to 150 feet above the Ames 

 limestone. A thin limestone appears occasionally at a few feet below 

 the Pittsburg and a 2-foot coal bed is at 73 feet, possibly the Jeffers of 

 more southern localities. The Harlem coal bed is double in some places, 

 the upper division directly under the Ames, and the lower, occasionally 

 of workable thickness, at 20 or even 30 feet lower and resting on the 

 Ewing limestone. Still lower is the Patriot coal of Lovejoy, about 40
