of Potato hill, Potsdam shales lie in contact with Burnet marbles. To- 
wards the top of the escarpment fossils said by Professor Hill to be from 
the horizon of the Trinity sands, the base of the 4,000 feet of Cretaceous 
strata, are quite plentiful. These are about on the level of the Potsdam 
fossils not two miles away. 
“The contact of the Carboniferous with granites, which are overlain by 
horizontal sandstones, and of the Potsdam sandstones and shales with 
Burnet marbles at three different localities, suggest the presence of a 
system of faults — vertical displacements — which must be taken into 
■account while considering the level of the central area when the Creta- 
ceous was deposited. 
“The , injection of granitic material into the Packsaddle schis'ts; the clean, 
fault-like contact of the ‘'Shinbone’ Carboniferous with the granites; and 
the apparent formation of the lower beds of the nearly horizontal strata of 
the Potsdam from the decomposed constituents of the underlying granites, 
all point out the post-Packsaddle and Pre-Potsdam age of the latter.”
