feet of coal without any persistent parting, though there are many insig- 

 nificant partings which continue for but a few yards. The coal appears to 

 be more sulphurous here than it is nearer the railroad, and the ash is 

 greater. 



. The bed was followed northward from the railroad for several miles, but 

 its structure there is similar to that seen in the pits on the railroad. 



The dip throughout is north-westward, and the undulations with respect 

 to the track are due to curves in the railroad. 



The especial feature of the bed here, aside from its thickness, is its 

 freedom from sulphur. In the Ligonier valley of Pennsylvania, according 

 to Mr. McCreath's analyses, the sulphur in Upper Freeport coal varies 

 from 1.414 to 4.789, and the coal rarely yields a firm coke. The ash varies 

 from 3 to 6 per cent. Further south, in Upshur and Randolph counties of 

 West Virginia,* the sulphur is high, and the ash is considerable even when 

 the coal is best. 



"Within the area immediately under consideration, the coal from this bed 

 yields an excellent coke. The Austin Company has found a ready market 

 for its product, which in Chicago competes on even terms with the Con- 

 nellsville eoke. Several car loads of coal from the vicinity of Tunnelton 

 Avere sent to Connellsville and there coked. Two lots were sent to the 

 Cambria Iron Works, where analyses were made by Mr. Morrell with the 

 following results : 



Car No. 1, made from sound coal : 



Carbon 93.64 



Sulphur 0.53 



Ash 6.83 



Car No. 3, made from outcrop coal : 



Carbon , 88.05 



Sulphur 1.41 



Ash 10.54 



Coke made from coal obtained at another opening was sent to the Edgar 

 Thompson Steel Works, where it was analysed by Mr. S. A. Ford, with 

 the following results : 



Fixed carbon 88.163 



Volatile matter 0.875 



Sulphur 0.887 



Ash 10.125 



These tests seem to have been sufficiently extensive to determine the 

 value of the coal for coking purposes. The loss in coking, as reported by 

 Mr. M. L. Schaefer, Superintendent of the Austin Company, is about 33 

 per cent, indicating a composition very nearly like that of the Pittsburgh 

 coal bed in the Connellsville basin.

 Virginia, by the writer, read before this Society on February 5, 187-5.
