The first analysis is derived from the coal of the entire seam, as 
shown inaroom. ‘The second 1esult was got from sampling the loaded 
railroad cars. The third analysis was of a single block selected as the 
best of the seam (see page 148). 
Between Dell Roy and Sherrodsville there are numerous country 
banks, in all of which the coal is found in good quality and good thick- 
ness. Among them may be named the banks of Pearch, Tholy and 
Yant. All hold the seam in fair volume, but best of all, they indicate 
the wide extent of the general field. 
At Sherrodsville the seam is a little lighter in volume, but this loss 
is more than compensated in an increased steadiness. The coal runs 
about 4 feet in thickness. Its structure is shown in the following
