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. 88, 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 WaaHaneten township, not far from 
Brainerd’s Mills. At other points, where the strata are cut toa sufficient 
depth to expose this bed, it was not observed. 
Coal No. 71s 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
