Sep 18 Wednesday. Spent the morning examining the various quarries near Odds Corners. I examined the quarries to the right of the dallsburg one while Beecher visited the one about half mile to the left of the same quarry. The entire series of quarries here begin a little below the Homogreene zone and continue to the top of the Coey- mans which is underlain by the Onondaga. In the Dallsburg quarry we again found more crinoids and Beecher disc- covered the crinoid bed. There can be my doubt that a coral colony exists here. He gave the two quarrymen full instructions to preserve are they find and believe they will soon send us a lot. The section following is a composite of the quarries near Odds Corners.
