400 GEOLOGY OF OHIO. 
The stratum in question is a so-called blackband deposit, imme- 
diately over the Lower Kittanning coal (No. 5), occurring at a few 
points in German township, in Holmes county, and perhaps also in 
contiguous territory. Professor Andrews describes it as follows: 
“Quite to my surprise, I found very large deposits of blackband 
over coal No. 5. At one point, where coals No. 6 and No. 5 are both 
well exposed, the shales between the two seams, here 18 to 20 feet apart, 
are very thickly studded with large nodular masses of ore, and hun- 
dreds of tons were exposed in the immediate neighborhood. Buta half 
mile away, we find 10 feet or more of the black bituminous shale over 
No. 5 so largely charged with iron in even diffusion as to constitute a 
blackband ore. . . North about a mile and a half is an extensive 
and elevated ridge where the exposed blackband over No. 5 is 10 feet 
thick. It is of equal thickness at another exposure in the same ridge 
about a mile further north. About 24 miles in a northwest direction 
from the last-mentioned point is another exposure where the blackband 
ore is equally thick, 7 feet 6 inches being in sight, with probably con- 
siderably more below.” 
Analyses were made of two of these deposits, one of the analyses 
being supposed to cover 7 feet 6 inches of ore, and the other 5 feet 6 
inches. The samples yielded of metallic iron, 27.32 and 22.62 per cent., 
respectively. These figures place the ores, as Professor Andrews justly 
remarked, on a level with the Tuscarawas blackband. 
The table of analyses is given herewith from Professor Andrews’s 
report : 
““T give, in the following table, the results of the analyses of these 
ores over coal No. 5, and also of the blackband over No. 7, from Tus- 
carawas county, copied from the Ohio Geological Reports. All the 
analyses were by Prof. Wormley. 
The analyses show that the blackband ores over coal No. 5 
are of excellent quality, and compare favorably with the famous black- 
band ores over coal No. 7, in Tuscarawas county.” 
No. 1. Blackband over coal No. 5. 
No. 2. Blackband over coal No. 5. 
Nos. 3, 4, 5 and 6, are Tuscarawas blackbands over No. 7 coal.
