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 mat kings 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 benches. The heavier bedded lime- 

 stone is quite free from inorganic sediment, and is a deposit in 

 deeper and purer water. The heavy bedded brown sandstone 

 marks some change bringing about a ureat 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 occur 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 .*eed cones of 

 gymno^perms, marine fucoids, and long, 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 aie 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 laminae 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.
