Page 291 - ... and thus complete vertical sections are difficult to obtain. The imperfections of the sections naturally strengthened the prevalent opinion of the non-continuity of the coal beds, and they were frequently regarded as sporadic and almost valueless as geological horizons. It is undoubtedly true that the normal condition of a Barren Measure coal bed is to be small, slaty, variable, and worthless for practical purposes. There seems -to be no doubt that at the time of the deposition of these rocks...

Page 78 - At the outcrop at the mouth of the mine the bed shows 8' 6" thick, including clay partings. The coal is lowered down from the mine by an incline plane. This places it on to the Salisbury and Baltimore railroad, which has a short branch up the ravine to the mine. The daily shipment (September, 1876) is about 200 tons. A specimen of the coal forwarded to the Laboratory of the Survey in Harrisburg yielded on analysis (AS M'Creath.) r. "Water 1.385 Volatile matter 21.470 Fixed carbon 69.352 Sulphur .763...

Page 23 - Sandstone ; from thence to the Serai Conglomerate the rocks are well known. The hiatus in the section does not amount to as much as 100 feet, for 500 feet of Barren Measures have been measured, and the group is here certainly not in excess, if at all, of its normal thickness of from 550 to 600 feet. The developments between Berlin and Pine Hill Church are . very complete. By their aid the several coal beds and limestone strata may be easily followed throughout this distance. The following compiled...
