below Brocket's bridge on the east bank of the creek. The rock of the falls is of slate, and 

 so also is the west bank. Where the Trenton limestone appears from under the slate, is the 

 point to commence ascending the creek, so that the upraised slate may be seen to the greatest 

 advantage. The upUft consists of the calciferous, presenting its usual wall-like appearance, 

 rising about seventy feet or more, and capped in part with the birdseye. In ascending the 

 creek from the Trenton limestone, the Utica slate, with its thin layers or flags of interposed 

 impure limestone, appear layer by layer, the curve and elevation gradually increasing from 

 that point, and finally attaining the height of at least sixty feet ; the slate, from the angle of 

 the curve where highest, holding a vertical position.
