"In the afternoon tried to see contact between the Niagara and Clinton but failed to find the place where Williams had seen it. The Niagara at the supposed base has molds of a Pentamerus near Morgans but with a very curved dorsal valve and without fold or sinus. These holes in the dolomite are very common. The Niagara is a heavy builded grey dolomite, in places gummish, that weathers into thin flakes. In general it is devoid of fossils. Williams states that below these Pentameres he observes the Clinton with Leptoceras planicostatum. We did not see this but still came and far away from the cliff we again saw the fossils like those collected yesterday. One Eridophyllum in the Clinton was at least 30 inches across. The reef character of the limestone was again seen here. Monitwaning Aug 7-1912, Wednesday. Rained all day and remained at Queens Hotel.
