JEFFERSON COUNTY. 773 



Lenticular nodules of pyrites occur here weighing from one to fifty 

 pounds. The pyrites band is persistent, and the coal is easily mined. 



The rocks between Coal No. 8 and the railroad level show little of 

 interest. The Crinoidal Limestone was seen at several localities along 

 the creeks emptying into the Ohio, and seems to hold a regular horizon 

 about two hundred and twenty-five feet below No. 8. On Mclntyre's 

 Creek, a thin coal about six inches thick occurs nearly one hundred feet 

 below that bed. 



Near the mouth of Rush Run, Messrs. Peck & Rumsey mine Goal No. 6,. 

 by means of a shaft two hundred and sixty-eight feet deep. The coal 

 is seven feet thick, including a roof coal of two feet, which is very poor 

 and full of pyrites. Followed north-westward in the mine, this roof 

 thins out and leaves five feet of good coal. Pyrites occurs throughout 

 the bed in nodules, but is irregularly distributed. The lower bench is 

 much softer than the upper. This coal yields a brilliant gas, but owing 

 to the large percentage of sulphur, cannot be used profitably in gas 

 manufacture. The slack makes a handsome but not compact' coke. Fire- 

 damp accumulates in the abandoned portions of this mine, but does not 

 prove troublesome. 



Wayne Township. — Here Goal No. 8 lies far up in the hills, while the 

 general surface is rather lower than in Smithfield township. The aver- 

 age altitude of the coal above the Pan-Handle Railroad is probably not 

 far from two hundred and sixty feet. It is worked near Bloomfield at 

 various points along the road leading from Unionport to York. At 

 Bloomfield the main coal is from four feet six inches to four feet nine 

 inches, and the roof coal is about one foot thick. 



About half a mile south from Unionport this coal is mined by Mr. J. 

 Ferguson and Mr. S. Cannan. At a short distance from these openings, 

 which are two hundred and ninety feet above Unionport, the following 

 section is seen in the road : 



1. Partially exposed, chiefly sandstone with two layers of 



limestone -- 100 feet. 



2. CoaZ iVo. 10, slaty and worthless 2 " 



3. Arenaceous shale 69 " 



4. Coal No. 8 4 " 3 inches. 



5. Fire-clay - 1 " 



6. Ferruginous limestone — --. 1 " 



Here, then, the interval between 8 and 10 has been reduced to sixty 

 feet, and the strata intervening between Coal No. 8 and the sandstone 

 under Coal No. 10, have entirely disappeared, viz.: one hundred and 

 fifteen feet of limestone, twenty-five of sandstone, and the included 

 Coals No. 8a and 8c, all of which occur in Mt. Pleasant township. 



In the section just given, Coal No. 8 appears to haTe no roof coal. At
