GEOLOGY OF OHIO. 107 



In the eastern part of Hanover township the summit of the divide is 

 occupied by the highly colored shales of the Barren Measures, beneath 

 which are seen, near Gilford, Coals No. 7 and No. 6, occupying their 

 normal positions. 



New Lisbon and Vicinity. — Passing over into the valley of the Middle 

 Fork of the Little Beaver, we find, above New Lisbon, in the southern 

 portion of Salem township. Coal No. 6 attaining, in some localities, a 

 thickness of ^ from six to seven feet, as on the Shelton, Arter, and Teegar- 

 den farms. On the Martin farm Coals No. 6 and No. 7 are both exposed 

 in the same section. No. 7 is here but two feet in thickness, but very 

 pure. Coal No. 6 lies sixty feet below it, and is four feet in thickness, 

 having its typical character. At Teegarden's mill the valley is cut 

 lower. The limestone under Coal No. 6 is here exposed in the hillside, 

 and Coal No. 5 is seen in the becl of the stream. 



Further down the creek Coal No. 4 is cut through, here consisting 

 mainly of a mass of- black shale containing a large amount of nodular 

 ore, and eight inches of coal. Below it, near the level of the creek, is a 

 bed of blue limestone, and under it Coal No. 3. This has been quite ex- 

 tensively worked by Mr. C. H. Andrews, and shipped to Niles for use in 

 the rolling-mills, and also largely manufactured into coke on the spot. 



It is here three feet and a half thick, highly bituminous, and contain- 

 ing considerable sulphur. The fire-clay beneath it is six to eight feet 

 thick, and is worked for the manufacture of fire-brick. 



Above the black shale which incloses Coal No. 4, an earthy limestone 

 is found, which is, perhaps, the eastern extension of the Putnam Hill 

 limestone, so largely developed in the Tuscarawas Valley. Above this a 

 trace of coal (No. 5?) is seen, nearly cut out by sandstone. Still higher 

 in the hills is found the white limestone — the Freeport limestone of 

 Pennsylvania — here four to six feet in thickness, of a light color, as its 

 name implies, and furnishing a much whiter lime than most of the Coal 

 Measure limestones. 



From this point to New Lisbon, and below, the walls of the valley are 

 made up essentially of the same elements. The stream runs upon tha 

 sandstone, which lies below Coal No. 3. 



Coal No. 3 has been opened at a great number of localities, and in 

 former years was extensively worked. On the north side of the stream 

 it varies in thickness from three to four feet, and is of fair quality. On 

 the south side it is thinner, and over a considerable area seems to have 

 nearly run out. As usual, the shales above the limestone over No. 3 con- 

 tain much nodular iron ore, and large quantities of it have been dug from 

 the alluvial lands bordering the creek, where it has been left in the 

 erosion of the valley.
