The rocks along the channel of the creek above these falls are called 
Genesee shales by Prof. White; but at the brink of the falls the pro- 
fessor states that the creek has cut down to the Hamilton sandstone, 
when it descends 75 feet vertically, and then passing out through a 
narrow channel descends another 50 feet. 1 
No. 1476 B3. — From the ledges along the side of the path below the 
lower falls. Here the shales are more argillaceous than those along the 
path by the upper falls, and fossils are more common.

No. 1476 B4. — A prominent ledge of rocks south of the road, 1 J miles 
up the falls road from Bushkill, and opposite sign board " one-half mile 
to Bushkill Falls." The rocks are moderately coarse arenaceous shales. 
Fossils are not very common, trilobites being the most abundant. It 
seems rather remarkable that Prof. White, when describing the Hamil- 
ton sandstones, should state: " Not a single specimen of a trilobite 
"was observed in all this thickness of rock, at the many localities where
