slightly smaller than that of the trap, or the same as the obser- 
vation taken in the brook. 
In some of the lower fine grained calcareous shales sun cracks 
frequently occur and together with trail-like markings and 
carbonaceeus impressions of branching fucoid-like plants point 
to shallow water or tidal conditions prevailing during the 
deposition of the lowest layers. The fineness of the material of 
these lowest layers also indicates a very gradual quiet submer- 
gence of the disintegrated Trap rock and the absence of heavy 
waves upon the subsiding beaches. The heavier bedded lime- 
stone is quite free from inorganie sediment, and is a deposit in 
deeper and purer water. The heavy bedded brown sandstone 
marks some change bringing about a great increase of inorganic 
sediment. Whether it was a re-elevation bringing the area 
nearer shore, or advent of currents carrying such sediment is at 
present undetermined. 
Fossils oceur in the underlying shale and limestone, altho’ 
they are, as a rule, poorly preserved. Among those collected 
are fish scales and teeth, objects resembling the seed cones of 
gymnosperms, marine fucoids, and Jong, tapering, generally 
straight, objects that are thought to be the shells of cephalopods. 
These occur in the limestone and calcareous sandstone often in 
great profusion and may reach a length of eight or ten feet, and 
a diameter at the larger end of eight or nine inches. The 
smaller ends are rounded, and usually about one, though some- 
times two or three, inches in diameter. They are cylindrically 
or longitudinally knobbed, hollow in the centre, and composed 
mainly of a red jasper. That these forms are of organic origin 
and are not concretions is indicated by their similarity in form 
and by their lying, in one bed, in such numbers that they cross 
each other in every conceivable way, but always the character- 
istic form of each individual can be determined. In all cases 
the finer lamine of the beds are pressed down beneath by the 
weight of the object, and those deposited after curve up over it 
without interruption. Other forms occur here also. One cf 
these was twenty-seven inches in diameter and appeared cup- 
like in shape.
