Borings for salt and oil made in various portions carry the section 

 much lower. At Freeport a bed said to be seven feet thick was struck 

 at about one hundred feet below No. 35, and at New Market it is reported 

 four feet at about the same distance, while twenty-five feet lower another 

 seam was found five and one-half feet thick. The upper is undoubtedly 

 Coal No. 6, worked extensively at Urichsville, and the lower is Coal No. 

 5, worked at Trenton, Tuscarawas county. These two seams may prop- 

 erly be added to the list of available coals, as there are many localities 

 in Freeport, Washington, and Monroe townships where Coal No. 6 can be 

 reached by shafting to a depth of not more than sixty feet, and Coal No. 

 5 is not likely to be more than thirty or forty feet below it. 



Lower Barren Group. — With the exception of No. 38, which, as the 

 equivalent of the Mahoning sandstone, is the upper member of Rogers's 

 Lower Coal Group, the strata below No. 21 of the general section belong 

 to the Lower Barren Group. The variations of the eoal seams are as 

 striking as in Pennsylvania or West Virginia, and changes in the other 

 strata are so frequent and abrupt as to cause much difficulty in recon- 

 ciling local sections. 



The Mahoning sandstone is observable only in the south-western por- 

 tion of the county, in Washington township, along the Stillwater. As 

 seen here it is usually a coarse-grained rock, containing numerous layers 

 of- conglomerate. It is slightly ferruginous, and light olive in color. 

 Though too soft for use in door-sills or steps, it answers admirably for 

 ordinary building, and makes a handsome stone. It can be split and 

 dressed with great ease. 



Coal No. 6a was seen only in Washington township, not far from 

 Brainerd's Mills. At other points, where the strata are cut to a sufficient 

 depth to expose this bed, it was not observed. 



Coal No. 7 is well developed in Freeport, Washington, Franklin, and 

 Monroe townships, and is worked in all of these to a greater or less ex- 

 tent. In Freeport township it disappears under the Stillwater a short 

 distance south from Freeport, near which place it is worked by Mr. Leeper. 

 At his bank the coal is about three feet thick, with a clay parting one- 

 half to one and one-half inch thick a little below the middle. Near the 

 top is a thin pyrites streak, and nodular pyrites is found here and there 

 throughout the bed. The pyrites is surrounded by soft coal, and is easily 

 separated. The coal here is of moderately good quality. A number of
