150 Stand. 46. Mayville, Plat. panderi rarest common in an argil. limestone. Quarry is about 10 ft deep, 970 ft. U.S.G.S. reading [illegible] using barometer. and therefore subject to error. 47. Arg. Placene rock, apparently with Plat. panderi but no good fossil. 48. At 894 about, U.S.G.S. Plat. panderi Dalmarella accidentalis + one Weberill, sinmata. Apparently also are Prasopna.

On summit S of 51, is Devonian chert, with Plat. lyracmired w/chert at base as though the Devonian lime had rested directly on the Upper Mayville. North of 51, is typical Eden with Plat. and [illegible] common. Dalmarella common out in a few layers, rare elsewh. Stephomena Halli rather rare, Prasopna sinata abundant. Eden section about 50 ft. Fault between Eden + Mayville perhapsly E+W, in dir. generally S.W. 151 52. Eden with 2 specimens of Primu- clens, also Plct. crummites ? Dalmarella, Rather numerous limonites, on both sides of the road. 53. Top High Bridge in the Vanuxemia in chert at top, also Orthni large specimens. Must be the lower Mayville bed. Above this is the basal part of the Carbon will not well exposed. At 885 i top of High Bridge, U.S.G.S. 54. High Bridge top occurs at a same level = 885 U.S.G.S., in woods along its road before reading 54. The lime vein at 54 is much more nearly but this main vein is slightly runs a little east of north, but not straight, a little zinc bleas is associated with the limete. The High Bridge + Lexington run west of the river. The counter rock east of this vein was not exposed at time of visit. 55.
