Excerpt from book: THE VEINS OF COAL AND THEIR DEPTH. The coal measures, or carboniferous formations, consist of a succession of hard sandstone and black or bluish slate and shales more or less evenly distributed. They are not uniformly laid and are not to be found in the same horizon of the coal measures throughout the anthracite coal fields. As a general rule, however, it may be said, that the upper part of the coal measures consists of softer rocks than the lower sections, although the various rocks may be found at any horizon. The coal measures vary from 100 feet to 3,300 feet in thickness. With the variety iiTtEelr thickness, tKe number and richness of the veins vary. At Tamaqua, the carboniferous formations are 2,300 feet thick and contain 21 coal beds with an aggregate thickness of 126 feet of coal. A short distance from Tamaqua, one bed of the Mammoth vein is 114 feet thick. At Pottsville there are about 3,300 feet of coal measures, with 28 individual beds with an aggregate thickness of 154 feet ojf coal. In the eastern half of the Western Middle field there are 13 individual beds with 110 feet of coal, and at Shenandoah, the Mammoth vein reaches a thickness of 100 feet. This same vein in Black Creek in the Upper Lehigh region is between 60 and 90 feet thick. In the Northern field in the neighborhood of Scranton, the beds aggregate a thickness of 72 feet, while in the vicinity of Wilkesbarre, there are 13 beds of coal having a total thickness of 94 feet. These estimates of the thickness of the coal are not to be taken as the amount of coal that can be marketed, because they contain impurities such as slate and bony coal. The veins vary greatly in richness, freedom from faults and lay either favorable or unfavorable to mining operations. Some of them are only a few inches thick, whil...
