Not illustrated. 1875 Excerpt: ...else in this State are there so many coal-beds, or such an aggregate mass of coal. At many other points, however, there is a back bench upon the main conglomerate containing these upper measures. The Main Sewanee, the Kelly, the Haley, the Wheeler and Rockwood veins, Prof. Saflbrd thinks, are all the same bed, and are all above the main conglomerate and included in the upper coal-measures. The following section of these upper coal-measures of Tennessee is given by Prof. Safford, the letters in parentheses being added, and was taken at Colonel "Wheeler's, in Campbell County, about four miles in a southwest direction from Jacksboro'.

If called upon to fix it, provisionally, he would make it bed 13; neither was he able to ascertain how high it was above the conglomerate. The small rider, one foot thick, nine feet above it, with shale and fire-clay between, the stigmaria in its floor, and its position in the series with three other good seams, and then 512 feet of Barren Measures with only one-foot seams in it, and the two other seams, apparently in the upper coal-measures, corresponding to the Pittsburg and Greensburg, gives the section a strong general resemblance to our Pennsylvania system; and, if so, the above represents the whole of it.
