Excerpt from Coal: Report of Henry E. Colton, Geologist and Inspectors of Mines on the Coal Mines of Tennessee, and Other Minerals, to A. W. Hawkins, Commissioner, Agriculture, Statistics and Mines The superficial area in the State of Tennessee, covered by coal 2bearing strata, amounts to square miles, but this does not fairly represent the amount of coal in the State, as all this area has at least one seam of coal, a large proportion more than two, and a very considerable area has six or more workable seams. It is thus seen that the mere area of a coal field may be a very poor indica tion of the quantity of coal it contains, and without an examination into the thickness of the seams, and the quality of the coal therein, any judgment formed from area alone may be very incorrect. Missouri contains vastly more coal area than Tennessee, yet one seam in Tennessee is worth more for economic purposes than all the coal of Missouri.
