  DeRuyter, Madison Co., N.Y.
Monday, October 8, 1888 -
  This forenoon, I have identified the Tully Group in a gorge on Lot [[strikethrough]] 20 [[/strikethrough]] 35 DeRuyter, Madison Co. It forms the top of a series of Cascades, the bottom being, as usual, in the Hamilton Shales. 
From my observations on this hill, I am convinced that the Tully also cuts the next hill north.
