In fragments of shale found in the drift near Kentville, by 

 Haycock, are impressions of Estheria of two slightly different types, 

 both of which must be provisionally called E. ovata. The shale 

 fragments were evidently derived from the Blomidon shale, and 

 they are very similar to some of the hard barren shale exposed at 

 Rossway.

 the Acadian area is a part of the Newark system, and further shows 

 a pronounced similarity between the Newark and the Lettenkohle 

 of Germany.
