above drainage, so that the loss by erosion is small. The following table 

 of analyses by Prof. Wormly indicates its character : 



No. 1, from C. Southerton's bank, Bayley's Run, Section 34. 



No. 2, from Section 7, Trimble township, lower part of seam. 



No. 3, " " " upper 



No. 4, from Chappalear bank, near line between Dover and Trimble. 



No. 5, from Allen bank, mouth of Mud Fork. 



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 1.13, of which all, except 0.49, pa'3ses 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, 2.16 ; 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 tor the British Admiralty, the average amount of sul- 

 phur in thirty-seven (37) 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
