A peculiarity of this mine is, that the 10-inch cannel is a market- 
able coal. It yields about 10 per cent. of ash, but burns cheerfully, 
and makes in some respects a desirable grate fuel. If a careful 
selection is maintained, a good quality can be assured, but part of the 
bench is long-grained and high in ash, degenerating into slate. Per- 
manent market is not yet assured for this part of the seam. 
The Sand Run coal ranges from 7 to 94 feet. On the Carbon Hill 
side, the seam does not often overrun 7% feet. 
The structure of the Carbon Hill seam is represented in the 
following figure. (Mine No. 17): »
