TUSCARAWAS COUNTY. 65 



Huff's Run, at Mineral Point, it yielded four and a half cubic, feet of gas 

 of high illuminating power. This gas, however, required considerable 

 purification to free it from sulphur. The coke formed in the gas retorts 

 was pronounced first-class. 



Coal No. 5 is the seam worked for many years near Bolivar ; it is there 

 from three to three and a half feet in thickness. About Zoar it is found 

 on both sides of the Tuscarawas, showing very much as at Bolivar, in 

 the mines belonging to the Zoar Community, west of the river, worked 

 for some years by Mr. Medill. This seam at one point was folded upon 

 itself and thickened to thirteen feet. At Mineral Point it shows a sim- 

 ilar disturbance in the mines of Mr. C. E. Holden. This peculiar phe- 

 nomenon was occasioned by the forcing out of a belt of coal from its 

 natural position over another part of the same seam. The force by 

 which this displacement was produced seems to have acted laterally, and 

 affected the coal in a belt of about one hundred feet wide. In driving 

 one of the entries in the mines at Mineral Point, a "horseback" was en- 

 countered, formed by the descent of the roof shale, which had evidently 

 been forced downward, and was very much broken up. After cutting 

 through this, the coal was regained, but here refolded on itself. In some 

 places a layer of shale was intei posed between the two strata of coal, in 

 others they were in immediate contact. After passing beyond the dis- 

 turbed belt the coal seam resumed its normal position and thickness. 



On the south side of Huff's Run, at Mineral Point, Coal No. 5 has a 

 thickness of about four feet, and appears better than in any other local- 

 ity where it has been opened in the county. Here it underlies a broad 

 table land, and seems capable of supplying a very large amount of ex- 

 cellent coal. 



At the old Fairfield Furnace, three miles below Mineral Point, Coal 

 No. 6 is found to be two feet in thickness ; at Dover it is the seam mined 

 to supply fuel to the salt well, and has here a thickness of about three 

 feet. From this point it runs through the hills on the west side of the 

 Tuscarawas all the way to and below Port Washington; it is generally 

 thinner, however, in this direction, rarely exceeding three feet in thick- 

 ness. It is opened at the new furnaces below Port Washington, and 

 shows here a thickness of two and a half feet— a moderately good coal. 

 On the river bank, near Burton's ore-shoot, it was formerly worked, and 

 is said to have been four feet in thickness. 



At Lock 17, Coal No. 5 is two feet in thickness, about twenty feet below 

 Coal No. 6, and seventy feet above the Putnam Hill limestone ; the lime- 

 stone is here one and a half feet thick, underlain by one foot of coal. 

 At Trenton, Coal No. 5 is thirty feet below No. 6, and has been worked
