HOCKING VALLEY COAL FIELD. 965 
_ The great value of the coal in this portion of the field is, in part, 
due to the fact that the two lower benches are so fully developed here, 
their aggregate thickness equaling, or slightly exceeding, 4 feet. The 
composition of the Carbon Hill coal is shown in the following 
analysis :

There is but very little coal in Ohio that is better than this. 
The Consolidated Coal Company’s mine on Sand Run is mining 
84 per cent. of its coal at present by machines. The Butler or Harri- 
son machine is used here with great satisfaction. This mine commands 
the coal of 180 acres, and is of exactly the same quality as that last 
_ described. ‘The coal is at long intervals cut by clay veins, and the 
roof rock sometimes comes down into the coal, but no very serious 
interruptions have yet been encountered. The use of the drill in 
proving territory in front of trouble in the seam, is coming into 
general use. The drill isa much less expensive tool with which to 
explore than the miner’s pick. 
Sackett and Smart’s old mine proved very faulty, the coal being 
cut down and out through so much of it as to make the mining un- 
certain and unprofitable. This company has a new lease, just beyond 
the old Somers mine, and the drill shows 9 feet of coal, including the 
cannel, in that direction. The coal is entirely represented by that of - 
the Somers mine. 
Longstreth’s Mine, now No. 19, of the syndicate, is in the same 
noble body of coal that is now being considered. Five Lechner 
mining machines are in operation here, and have been from the opening 
of the mine. The mine ranks amongst the largest, as well as the best, 
of the Hocking Valley. The structure and composition of the coal 
are represented in the preceding figure and analysis, the coal being 
continuous and identical with that of the mines before named. The 
composition is given on a succeeding page.
