At N. Mt. the Beecraft has a thickness of not less than 32 feet. The fossils are from the middle, Echinocanins more common about 25 feet. At North Mountain, the Oriskany has a thickness nearer 20 feet. It can be more seen on the north side of the R.R. cut. In lago Hocus thinnest and saw a very large Spirifera one of the forms of S. munchionii, regalete and not very timid with broad low rounded plications. The Tuscarora passes at N. Mountain. Probably cut under the Oriskany appear to be shoved up against the Beecraft above. at N. Mountain while at Hedgesville it is not so far and therefore reforms the Tuscarora. All of the Tuscarora may therefore not be exposed.
