THE LOWER COAL MEASURES. 239 
These figures show a good coal. They are decidedly above the 
average for this seam. The coal has heavy cover, and quite a large 
areao f itis tributary to the mine. Like the Richards mine, it also lies 
near the outer margin of the Kittanning horizon for this region. 
Near Burton’s Switch, and in connection with the mines now 
described, the following general section was obtained :

There is one other important field of the Middle Kittanning seam 
(No. 6) in Stark county. It is in Osnaburg township. The coal has 
been worked here in numerous small mines for many years, and a large 
part of the supply of Canton has hitherto been obtained from this 
source. Since the building of the Connotton Valley Railway, two 
shipping banks have been opened near the village of Osnaburg, and are 
now in operation. The coal from this neighborhood has an excellent 
name. A small part of the seam is highiy valued as smith coal, and is 
often sold separately for this purpose at advanced price. In general, 
the product of these mines commands a higher price in the neighboring 
towns and villages than the other coals that the railroads supply. The 
seam is 3 ft. 6 in. thick, and although the seam lies quite high, being 
624 feet above Lake Erie, a large acreage is to be found here. The 
average composition of the whole seam is shown in the following 
analysis of the coal of the Osnaburg Coal Company :
