2 Anthracite formation of Wilkesbarre, &e. 
Harrisburgh, Columbia, and other towns on the river, where 
it sells at from $4 to $4 50 per ton. At Philadelphia, it 
brings from 30 to 40 cents per bushel. 
Very respectfully, your obedient servant, 
ZACHARIAH CIST. 
P.S. The accompanying view of one of our Coal Mines, 
presents a section sufficiently complete of the strata of most 
of them. 
Section of the strata at Smiru’s bed, on the West side of 
the river. Dip to the South, about 20°, 
1. Sand stone of the mountain, composed of coarse stone 
and quartz, from the size of shot to that of a pea, grain 
rather regular, used for building, very compact, and diffi- 
cult to dress—color dark. This runs of great thickness, 
ee in detached masses heaped on one another. 
2. Slate, with considerable quantity of minute fragments of 
mica interspersed, containing vegetable impressions, fif- 
teen feet thick. 
3. Micaceous sand stone, four feet thick, easily worked, 
and used for grind stones, for which it is well adapted— 
color light blue. 
4. Slaty coal, two feet thick, left to form the roof of the 
mine. 
5. Coal worked, eighteen feet. 
6. Tough fine blue clay, two inches. 
7. Sand stone, containing but little mica. The first part of 
this is easily bored through, but it becomes gradually 
harder. About thirty feet of this stratum is exposed—its 
depth is unascertained. 
Section of Bowman’s mine, on the east side of the river— 
dip to the north at about 15°. 
1, Coarse sandy schist, as you proceed in depth passing 
into argillite sixteen feet. This stratum contains vege- 
table impressions. 
2. Coal, twenty-five feet thick. 
3. Argillite, with pyrites imbedded, and investing the sur- 
face one foot thick. These pyrites seldom exceed one- 
fourth of an inch square, and are much flattened ; the
