"thrown into irregular masses and in places into round balls. Once the irregularities follows a dark bituminous sandy shale filling the depressions and the regular bedded, laminated in appearance, [illegible] sandstone. There can be no doubt that the section is here broken, and that the irregular layers go with the Lockport. Have a piece of the basal sandstone above the irregular layer. The sand rapidly becomes less and the beds become a fine grained crystalline dense dolomite. All of this in fine fab. These basal beds have no fossils of any kind. The same thing of contact between the Rochester and Lockport is there seen at Rochester, Niagara Falls and Swope- by. The lack of evidence for a break. As usual the most eastern contacts introduce sand, not seen even at Niagara Falls and certainly but a few grains at Swope."
