HOCKING VALLEY COAL FIELD 975 
of the output, however, seems to be kept up fairly well,’aside from a 
considerable increase in sulphur. | 
The main interruptions come from clay veins, which disturb the 
coal of a considerable territory in the southern parts of Sections 11 
and 17. In fact, an east and west line through this territory leaves the 
steady and unbroken portions of the seam to the northward. 
A little beyond Maple Hill Mine, on the Monday Creek branch of 
the railroad, the small mine of Juniper Brothers is located. The seam 
is found here of its normal measure and quality. The capacity of the 
mine is 10-12 cars daily. 
Throughout this field the rider seam of the Hocking Valley 
supplement is often found, but never mined. It is seldom more than 
2 feet thick, and generally much less. It is 2 to 4 feet above the top 
of the true seam. The composition of the Nelsonville coal will be shown 
in the table of analyses that follow:

These figures explain themselves. The chief feature is the in- 
crease of sulphur in coming southward from Ward township, and west- 
ward from Monday Creek. This element is by no means in excess for 
Ohio coals, but it is 2 or 3 times as large as is shown in the chief mines 
of the valley. | 
On the west side of the river, the following shipping mines are 
found, viz. :
