Good illustrations of peneplains arc seen here on all sides in the 
uniform hights to which the different rocks have been eroded. The 
gneiss schists sandstone and dikes rocks varying much in hardness, 
have been eroded approximately to the same level. Many other points 
in llu' i)liysiography of the region are impressed u])()n the students in 
their trips, (llacial drift rind slriations are abundant in and about the 
eity. 
On election day an all-day trip is taken to some point within fifty 
miles of the city. This fall it was up into the Hudson River high- 
lands. The West Shore R. R. was taken to Grassy Point and from 
there the class walked to Ft. Montgomery. On the way excellent ex- 
posures of Champlain clays were noticed and the consequent develop- 
ment of the brick industry. Near Stony Point where lunch was eaten, 
the Basal Triassic conglomerate and the contact of mica schist on 
the Cortlandt eruptive series were noticed. North of Stony Point fine 
exposures of Cambrian limestone were examined carefully for fossils 
but none were found." Farther north still tha class entered the high- 
lands with its Archean gneiss, trap dikes and celebrated scenery.
