The average percentage of water is 4, but little more than that of the 
Briar Hill, which is 3.84. The average percentage of ash—excluding 
that of No. 3, which is exceptionally large—is 3.77, comparing favorably 
with our best coals. The average percentage of fixed carbon is 58.10, 
while that of the sulphur is 1.15, of which all, except 0.49, passes off in 
coking. 
Prof. T. Sterry Hunt, in a. pamphlet on “The Hocking Valley Coal- 
field and its Iron Ores,” p. 42, says, in reference to the above analyses: 
“The proportion of sulphur in the Bayley’s Run seam; though somewhat 
larger than that of the Great Vein, is not large when compared with 
most other coals in Ohio and elsewhere. From the analyses of Ohio coals 
published by Prof. Wormley, I select a few samples. The average amount 
of sulphur in seven (7) samples of the coal mined at Cambridge, in 
Guernsey county, is 1.98 per cent.; that of nine (9) from Coshocton 
county, 2.21; of nine (9) from Stark county, 1.94; of ten (10) from 
Holmes, 2.15; and of seven (7) from Columbiana, 1.95. Of the coals of 
Great Britain, as appears from an extended series of analyses, made a 
few years since for the British Admiralty, the average amount of sul- 
phur in thirty-seven (87) Welsh coals was 1.42; of twenty-eight (28) from 
Lancashire, 1.42; of eight (8) Scotch coals, 1.45; and of seventeen (17) 
from New Castle, 0.94. The coke of Durham, esteemed in England as 
the best fuel for iron smelting, retains from 0.60 to 0.80 of sulphur. So
