256 GEOLOGY OF OHIO. 
The normal measures reappear here, though the points at which 
the two sections are taken are but a few miles apart. A number of 
these last-mentioned facts belong to Monroe township, Harrison county. 
This brief review has been made to cover the present development 
of the Lower Coal Measures of Carroll county, including also the state- 
ments necessary as to the Brush Creek coal. This does not include quite 
all the coal seams of the county, as one of the Barren Measure seams is 
worked ‘to a small extent in several townships, but principally in Lee. 
It is known as the Harlem coal. It is found about 40 feet below the 
Crinoidal limestone. It is of good quality, but its small volume pre- 
cludes the present possibility of its being made a basis of large work. 
The Pittsburgh coal comes into the county, so far as known, only as a 
“blossom” on the highest hills. 
Vil. COAL MINES OF TUSCARAWAS COUNTY. 
The type section of Tuscarawas county is to be found in the actual 
sections already reported in Figures XIX and XX. All of the work- 
able coals of the county are shown here in their relations to each other. 
There are six separate and distinct seams of coal that are mined in 
the county, but there are only two that attain any considerable value as 
sources of fuel, and in fact a single seam far outweighs all the rest 
combined. 
The seams that are mined in the county are the following, viz.: 
Upper Freeport coal. 
Lower Freeport coal. 
Middle Kittanning coal. 
Lower Kittanning coal. 
Brookville coal. 
Tionesta coal. 
Openings are frequently made to the Mercer coals, but these seams 
add little to the fuel supply of the few districts in which they are 
found, so far as is now known. | 
Of the coal seams that are worked, the Middle Kittanning (No. 6 
of Newberry) is by far the most important. The large mines of the
