134 GEOLOGY OF OHIO. 



son counties. In Jackson it regains somewhat of its traditional char- 

 acter and value, and is quite extensively mined and used as a furnace 

 coal. It is here from 3J to 4£ feet in thickness, is black and pure, resem- 

 bling in appearance, as it does in properties, the coal of the Mahoning 

 valley. It is, however, somewhat more laminated, and, perhaps, ap- 

 proaches nearer to the " block coal " of Brazil, Indiana. 



How far Coal No. 1 extends through the coal basin, south and east of 

 its line of outcrop, has not yet been fully learned. It is reported to have 

 been reached in borings made at Cameron's Mill, on Bull Creek, Middle- 

 ton township, Columbiana county, at the depth of 166 feet, and is there 

 said to be four feet in thickness. It is also said to have been struck in 

 two wells bored in the valley of the Little Beaver, near Williamsport ; 

 but in the oil wells bored at Smith's Ferry and Island Run no traces of 

 it seem to have been obtained. This is not positive proof, however, 

 that it was not passed through by all of them, as the boring was usually 

 done with a rope, and no attention was paid to anything struck in boring 

 unless it was oil. I have myself seen abundant particles of coal brought 

 up in the sand-pump from a well at Smith's Perry ; but in other borings 

 made at a distance of only a few rods no coal was reported to have been 

 penetrated. At Limaville, on the line between Stark and Portage, the 

 Briar Hill coal was unquestionably reached in the boring of Dr. Dales. 

 In a well bored by Mr. Swalm, at Canton, Stark county, Coal No. 1 is 

 reported to have been struck at a depth of 160 feet below the Zoar lime- 

 stone. It is said to be there 6 feet in thickness. Quite a number of 

 borings made in the vicinity of Canton in search of this seam passed 

 through it, but in all these cases it is reported to have been thin — from 

 6 to 30 inches. 



In borings made at the mouth of the Nimishillen, near Sandyville, 

 and at the Goshen salt well, above Dover, Tuscarawas county, the Mas- 

 sillon coal is said to have been struck, but I have not yet been able to 

 ascertain the truth of the report. In the boring made at the Sugar Creek 

 salt works the place of Coal No. 1 was distinctly marked, but it was 

 very thin. 



In the two wells bored at Urichsville two thin seams of coal were 

 passed through under that of the Zoar limestone (No. 3) ; and at the dis- 

 tance of 165 feet below No. 3 a mass of coal and slate, several feet in 

 thickness, was passed through. This may represent Coal No. 1, as no 

 coal was found below it. 



On the Ohio, below the mouth of Yellow Creek, a number of borings 

 indicated a coal seam of remarkable thickness, some 80 or 90 feet below 

 Coal No. 3, but when a shaft was sunk to it it was found to be mostly 

 black shale, and worthless.
