shales, 310 feet. 2. Middle gray and greenish sandstones, 820 feet. 

 1. Lower red shales and sandstones, 320 feet. 



At Quinnimont on the Kanawha River, the transition layers between 

 No. XI and No. XII are shown in the following sec'.ion : 



5. Black fissile slates and shales, 20 feet 



4. Thinly laminated, gray flags and calcareous shales contain- 

 ing in the upper part carbonaceous shales and strings of coal, 50 ft. 



3. Variegated marlites with some nodular limestones, 70 feet... . 



2. Gray calcareous sandstone, 20 feet 



1. Bright red shales, seen 50 feet 



No coal was found in this series in Huntingdon County. 



Prof. Wm. B. Rogers mentions a coal under tlie Conglomerate on little 

 Sewell Mountain, which he queries equivalent to the Sharon Coal of West- 

 ern Pennsylvania. He also notes the occurrence of a seam 4 feet thick in 

 subdivision b west of Lewisburg, Greenbrier County, Va., and of two 

 beds in Montgomery Co., one from 2 to 3^ feet thick, and the other from 6 

 to 9 feet thick composed priucipally of slate. 



2. Ths middle member (Mountain Limestone) is made up of red and gray 

 argillaceous limestone and red shale. The limestone and shale alternate so 

 irregularly that it is hardly possible to distinguish any well-marked subdi- 

 visions. The whole thickness of this member is 49 feet, the correctness of 

 which depends upon the identification of the variegated red and gray 

 massive limestone No. 224 at New Grenada with that at the quarry 

 worked by John "Whitney, near Todd P. O. 



The thickness of the series exposed at New Grenada is 35 ± feet. At the 

 quarry worked by Whitney the highest limestone stratum exposed is No. 

 229, and the low^est No. 221, making 3G feet in all. But if the variegated 

 red and gray limestone bed at New Grenada be the same as that near Todd 

 P. O., then we neither found the lowest stratum at the former locality nor 

 the highest at the latter ; but the lowest exposure at New Grenada is 14 

 feet above the bottom of the series, while the highest near Todd P. O. is 

 13 feet below the top. The possible error (in the event of the erroneous 

 identification of limestone No. 224) is 13 feet, which would make the 

 thickness 3G feet instead of 49.
