This difference in westward inclination of the two main coal beds is somewhat surprising and at the same time interesting. It implies that throughout this area there was a more rapid accumulation of shale forming material to the west during the interval between the production of the two coal beds. This excessive westward thickening averages 8 feet to the mile, the difference between the dip of the two coal beds. The general westward inclination of the _Cherokee shales as a whole along the south line of the state, as shown in Plates I and II, is about 20 feet to the mile. The westward inclination of the Lower or principal coal bed is therefore about the same as that of the Cherokee shales, while the position of the Upper coal bed is such that it is inclined to the general bedding planes of the Cherokee shales. The dip of the Cherokee shales to the north and west, in Cherokee county, is therefore quite marked, which dip soon carries them below the higher geological formations to the north and west, and to such a depth that in a comparatively short distance beyond the upper line of outcrop the accompanying coal strata become, for the present, unworkable. I The Intermediate coal stratum is as persistent in the constancy of its thickness and extent of occurrence as well as in its dip as are the Upper and Lower. Arcadia Area. At Arcadia three strata are found from which considerable coal is removed. The upper stratum comes within a few feet of the summits of Bunker Hill and Coal Mound, at which places it is mined. It resembles the Fort Scott "red"and is much used as a domestic fuel. The second...
