that it will be seen that the coal of the Great Vein of the Hocking Val- 

 ley and that of the upper or Bayley's Run seam are more than ordinarily 

 free from sulphur." 



This coal in a raw state will be found an excellent fuel for all domestic 

 and manufacturing purposes where its melting character is not objec- 

 tionable, and it gives promise of furnishing a better coke than any other 

 coal in the state. Experiments have been made in a small way by coking 

 it in a single new oven not thoroughly dried, at Shawnee, and under 

 these unfavorable circumstances, the product was a hard, bright metallic 

 coke, evidently containing little sulphur, which is highly commended 

 by good judges of coke. The following is the analysis of it, made by 

 S. B. Newberry : 



Carbon 86.95 



Ash 13.05 



Total 100.00 



Sulphur ■- 1.68 



This specimen shows a larger percentage of sulphur than the average 

 analysis of the coal would indicate, and probably larger than the average 

 of the coke. 



So thoroughly persuaded is Prof. Andrews, who has carefully explored 

 this region, of the excellent coking character of this coal, that he says 

 he is inclined to believe that in the future the Bayley's Run coal in the 

 Lower Sunday Creek region will be even more valuable than the great 

 seam underlying it. It has been mined for local consumption in some 

 half dozen places, and in all of them appears of excellent quality. 



Above the Bayley's Run coal are several thin seams of coal, none of 

 which have been specially explored, and none of them disclosing out- 

 crops which give promise of a workable thickness until the Pittsburgh 

 coal is reached. The latter belongs to the upper Coal Measures, and is 

 found in the hills east of Sunday Creek at an elevation a little less than 

 five hundred feet above the Great Vein. It ranges in thickness from four 

 to eight feet, is a soft, melting coal with a high heating power, but con- 

 taining apparently a rather large per centage of sulphur. Its character 

 and location will prevent its being mined, except for local consumption, 

 for very many years. There is doubtless much valuable coal on this hori- 

 zon, but it constitutes a part of the reserve supply for consumption in 

 the indefinite future, when the more valuable coals are approaching 

 exhaustion. 



IRON ORES. 



Prof. J. P. Weethee, who lives near the town site of Ewing, has de- 

 voted much time to the study of the iron ores of the lower Sunday Creek
