226 GEOLOGT OF OHIO. 



7a, except, perhaps, in the north-western corner. The section, as obtained 

 from Salesville to Washington, is as follows : 



FT. IN. 



1. Shales EO 



2. Limestone 2 0- 



3. Shales 55 



4. Crinoidal limestone 4 



5. Shales 12 



6. Sandstone 50 



7. Limestone 2 



8. Shales(8een) 10 



South-east of a line running north-east and south-wesfr through Wash- 

 ington No. 76 is not seen, but north-west of such a line it sometimes ap- 

 pears. Mr. Alexander Barton works it a short distance north of the vil- 

 lage. The coal is two feet four inches thick, and is of very fair quality. 



Oxford Towt^ship. — Just east from Middletown Coal No. 8 is worked by 

 Mr. Thomas Ford in section 31. There the following section was ob- 

 tained : 



FT. DJ. 



1. Coal 1 



2. Shale 1 



3. Coal - 4 2 



4. Fire-clay 1 6 



5. Sandstones and shales 147 



6. Crinoidal limestone 3 



7. Shales and sandstone to creek 40 



The coal is of good quality, but of rather less specific gravity than 

 that from other banks in the neighborhood. Mr. Boyd Forbes's bank in 

 section 25 has the same characteristics. The strata above the coal are 

 altogether sandstone for a distance of one hundred feet, and no signs of 

 Nos. 9 or 10 were seen. Nodules of limestone occur on top of the hill. 



Following the National Road from Middletown east, Coal No. 8 is first 

 seen in a deserted opening in section 20, belonging to Nancy Yurkle. 

 Near the Antrim road Mr. Bailey has made several openings. Here the 

 coal averages four feet, with one foot of roof-coal. The pyrites band in 

 the upper bench and the slate partings are well marked and persistent. 

 The coal is compact, of good quality, and generally free from pyrites. Two 

 and one-half miles east of Middletown Mr. McCullough has opened the 

 same coal by means of a shaft. The coal is three feet six inches thick, 

 and is regarded as of excellent quality. It contains many films of car- 

 bonate of lime. This bed continues accessible to the county line, and is 

 worked at several localities along the National Road. The rocks above 

 are sandstone for seventy feet, excepting a thin shale midway, contain- 

 ing a few nodules of limestone.
