reached is 4 ft.5 in. In this case the 4-inch slate dies out, and the 
cannel band becomes coal. hie 
The coal is taken without powder. It is strong, and mines large, 
the Black Diamond coal having a little advantage in this respect also. 
Ordinary mining makes about 1 ton of nut to 8 tons of lump coal, and 
1 ton of slack to 4 tons of lump. The nut sells close to the lump coal 
for domestic use, and the slack can be made to pay its way to market 
at least. The screens employed are % inch at Scott’s, and 14 inches at 
the other banks. The whole area of coal belonging to the several 
mines will aggregate perhaps 100 acres, the Scott mine having about as 
much acreage as the other two combined. A number of acres have 
been worked out, but no reliable estimate is at hand. 
There are other tracts of the coal in the vicinity. West of Pal- 
myra a tract of perhaps 50 acres has been proved. It was in fact the 
first large body of the coal that was struck in the explorations of 25 
years ago. Lacking facilities for transportation, the property is un- 
developed. 
A new basin is now being tested by sinking a shaft, 1? miles south- 
east of Diamond, by H. H. Gillingham and Company. The promise 
seems fair for a deposit of some value. 
The composition of the Palmyra coal is shown in the following 
analyses (Lord) : 
1. Palmyra Coal Company. 
2. Scott Coal Company. 
3. Cannel bench, Scott mine, bottom. 
4. Same, middle. 
5. Same, top.
