832 GEOLOGY OF OHIO. 
Passing over the hill to Sand Run, I found, about half a mile south of 
the road from Carbon Hill to Straitsville, an exposure of the Nelsonville 
seam, which gave the following measurements:

On the lands of the Crafts Iron Company, near the junction of Little 
Monday Creek with Monday Creek, the Nelsonville seam lies in the high 
hills west or north-west of the furnace. I made no measurements of the 
coal, but the seam is reported to be nine and one-half feet thick. The 
coal, as mined, appeared remarkably well. It mines in large blocks, is 
free from slate, and contains very little visible bi-sulphide of iron. 
Unless there is sulphur in other combination—which analyses only will 
detect—I should confidently predict that this will prove a very success- 
ful furnace coal. The coal will be brought down to the furnace by a 
tram-road, and the same road will bring down the ore. 
The valley of Lost Run reveals the coal in fine thickness, as we should 
expect, this branch of Monday Creek being the next one south of Sugar 
Run, where are the New Straitsville mines. At one exposure—at what 
was called J. D. Clarke’s opening—the coal was found to measure ten 
feet four inches, exclusive of the usual shale partings. On the land of 
the late William Ward, Esq., the lower eight feet of good coal were seen, 
the top not being uncovered. On the land of Thomas Barnes, the seam 
measured nine feet ten inches. In 1869, I obtained samples of the Lost 
Run coal—three from the Ward opening, and three from the Clarke bank 
—which were analyzed by Professor Wormley: No. 1 from middle of 
lower bench; No. 2 from middle of the middle bench. Nos. 8, 4, 5, and 
6 represented the upper bench in ascending order. Of these, Nos. 1, 2, 
and 4came from the Ward land, and the others from Clarke’s bank.
