GUERNSEY COUNTY. 531 
This ore, when roasted, will lose its water, volatile or bituminous 
matter, the carbonic acid of the carbonates of iron and lime, and all, or 
nearly all, of its slight amount of sulphur. There is hardly enough 
bituminous matter in this ore to serve as a fuel in roasting it. A sam- 
ple of the blackband ore from Newcomerstown, obtained by Mr. Gilbert 
for comparison, yielded 24.00 per cent. of metallic iron. Both ores are very 
free from sulphur and phosphorus. From more recent visits to Cassell’s 
Station, I am led to think the average of the blackband better than the 
sample analyzed. : 
CAMBRIDGE TOWNSHIP. 
This township contains Cambridge, the county seat of the county. A 
section was taken on the high and isolated hill a little south-west of the 
town, as follows:

15. Blossom of coal. 
(See Map XII., No. 6.) 
In this section No. 15 is the Cambridge, or Scott’s coal; No. 11, the 
equivalent of a seam found forty-two feet above Scott’s bank; No. 7, the 
equivalent of the cannel coal at Horatio Grummond’s, in Adams town- 
ship; and No. 1, the equivalent of the Anderson coal, near Campbell’s 
Station. This section, therefore, is a key by which the intervals may 
be judged elsewhere. A section was taken on Tunnel Hill, west of 
Cambridge, from the highest coal, on the very summit, to the level of 
the railroad track. The exposures were chiefly in a slide in the hill- 
side, in the approach to the tunnel on the west side of the hill :
