CARROLL COUNTY. 181 
county, varying greatly in hardness, color, and composition, but every 
where exhibiting the same grouping of fossils, which renders its identi- 
fication so easy and makes it so valuable a guide to the stratigraphical 
relations of a district. 
The shales immediately underlying the Crinoidal limestone contain a 
small percentage of iron. There are few localities, however, where it is 
concentrated, and in none is the concentration sufficient to afford a work- 
able seam of ore. In the neighborhood of Carrollton, both west and 
south, a seam of inferior blackband, varying from three to six inches in 
thickness, is seen three feet below the limestone. In the coal shaft near 
Harlem, Lee township, two seams of blackband are said to have been 
cut, one three and the other four feet thick. The shaft was closed at the 
time of my examination and no specimens had been preserved, so that 
no definite information could be obtained. It is most likely that dark 
shale has been mistaken for blackband, as no evidence of the latter was 
seen in any of the numerous exposures near the village. In the vicin- 
ity of Cannonsburg, Monroe township, the occurrence of ferruginous 
shale at this horizon has given birth to much excitement, and the oracu- 
lar statements of some would-be experts have done much toward rousing 
false hopes in the minds of the inhabitants. A number of localities in 
this township, said to show from ten to fourteen feet of blackband, were 
examined; but in every case the “blackband” proved to be only a dark, 
slightly bituminous shale, containing for the most part a very small per- 
centage of iron, and holding here and there an inch of lean plate ore. 
As the owners generally expressed themselves dissatisfied with the re- 
sults of merely physical examination, specimens of the shale obtained 
on the farm of Dr. Samuel Black were forwarded to Dr. Wormley, with 
the request that he would determine the percentage of iron. He reports 
its composition to be as follows:

In Bygown township, near Waynesburg, a good deal of money has been 
wasted in digging well-holes in this shale, the prospectors supposing 
that it is the extension of the blackband belt of Tuscarawas county. A 
little investigation would have shown that the horizon is too high, as 
the blackband, which is quarried only five miles from this locality, lies 
upon Coal No. 7, more than one hundred feet below this shale. A day’s 
careful examination by a competent geologist would not only have pre-
