A coarse grit, or quartzite, much resembling the coarse grit at 

 Mount Uniacke, has been already described as occurring at 

 Waverley, where it is especially distinguished by concretionary 

 forms and fossils, supposed to be the Palaeotrochis of Emmons. 

 Hence it has been marked on the map as Concretionary Quartzite. 



In the following section, made by Mr. Clarke in the spring of 

 last year, the concretionary quartzite occurs in that part of the 

 section enclosed within brackets, and it is the 431 feet of strata 

 at Waverley, composed of 421 feet of " whin,'' and 9 feet 3 inches 

 of slate, which I propose provisionally to place as the equivalent 

 of the 380 feet belt at Mount Uniacke.

 and 183, on North and South Course.
