heavy bedded dense crystalline crinoidal limestone in which also occurs Syphidula pulestro. Higher the blue limestone is in thinner beds and their gradually introduces more chert and goes a dull shale. Up to the Archolina bed the thickness is 44 feet I saw no guide from these beds, [illegible] Above the Archolina given the limestone are also this bedded dense crinoidal, measuring for 43 feet. This then is the contact with the Beecroft. The Beecroft is a series of heavy bedded darker with chert and more crystalline limestone than the New Scotland below. [illegible] has collected two specific concerns Syphidula pseudopulestro (the specimen does not show of the smooth exterior) and so by Dalmanite's tail. Thickness about 23 feet. Then follows a great mass of black bituminous smelly shale that weathers down into a blocky cherty material, which would begin in a 20 inch thin joint line. The lower 30 feet almost all shale. Then 12 feet of cherty then bedded blocky material. Then 6 feet of blue shale followed by 12 feet of blocky material. Then 6 feet of more cherty material that weathers out into greyish cherty blocks. Two faults then came in and a [illegible]
