1201B.
  Here, a few feet further down the hill, we find the Tully Limestone in force, a full 100 feet below the top
of the ridge, on the north bank of Gaylord's Gulf.
In one of the upper rocks, we find many Trilobites.
1201C. About 150 feet lower, is a fall in Gaylord's Gulf stream, about 50 feet.
This rock resembles, very strikingly, the Lower Section of Tully Limestone. Calciferous 
Arenaceous Shale.
The entire aspect of the rocks, in situ, 25 feet above the upper rock in the falls, is that of the Lower Section of Tully Limestone; but it is fully 150 feet lower than the Tully, found above.
