at this point, and deposited over the lower bench these fifty-two feet of 
sandy shale, above which there was again deposited patches of coal on 
the horizon of upper benches of the Great Vein. An opening in the 
Great Vein, on Section 5, Pleasant township, where it is in its proper 
position below the sand-rock, and a little north of the place where it as- 
sumes its normal thickness, tends to confirm this conclusion. It is there 
very irregular in thickness, in two benches, with compact sandstone 
parting. <A section is as follows:

South of this point, it assumes all of its best characteristics, and ap- 
pears a little above the bottom of the valleys, in thickness from nine to 
thirteen feet, and dipping to the south-east a little faster than the fall of 
the streams, so that in the south and east parts of Monroe, it is found 
beneath the surface of the lowest valleys. In the east part of South 
Lick township, it is somewhat thin and higher up in the hills, so that 
it is there easily accessible by drifting. 
The following is a section of this coal on Benjamin Saunders’s land,

On Rector’s Fork is a very fine exposure of the coal, where the stream, 
for a long distance, bas cut away the upper and most of the middle 
bench, and flows upon a solid bed of coal. |
