If the Pennsylvanian should be drawn at the base of these sandy- argillaceous li and shales both here and in the Catskills. * See below, and Monte page I did not see a trace of a Hastroid here today nor has anyone ever found me. They certainly are not from the Drapanocella limestone paper, and those gotten by Drillis must come from either the shale below or the argillaceous li. beneath. Beneath the argillaceous li. comes in the dark- Hue shales of the Carey. What their relations are here with the Judd fault cannot be determined because of the Chretone Fault. There is a part thickness of Carey here to judge by the valley on the 7th side of Limestone Ridge. Here is at least 100 feet of Carey. Over the Drapanocella Limestone is the Clinton Shale reported to have a thickness of 3000 feet. It has ferruginous sandstones. Ballis' various Drapanocella series sections show that the sedimentation is very variable. This is in har- mony with the fact of the beginning of a new period and one of very rapid deposition. * In the Benayan horizon I got large Pateclostium, Northen- ia, one cut end, and saw two others that I thought were Camptophyllum Torquium (small about 3 times in diameter).
