 runs in a westerly direction to IJattory Point, and the 

 eastern end of which is surmonntcd by an ancient camp. 

 The Mountain Limestone is nearly vertical, varying in the 

 main ridge from 10° to 15° on either side of the pei'pen- 

 dicular. Its northern or channel side is fringed with 

 Dolomitic Conglomeiuto, beneath which here and there Coal 

 Measui'o Sandstone is exposed to view. It is separated on 

 its southern flank from the Old lied Sandstone of Wood 

 Hill by a line of depression also filled with. Triassic beds, 

 beneath which in. all probability lie Lower Limestone Sliah)s. 

 A little band of Trias seems to sepiwate the main ridge 

 from the smaller ridge on which the battery stands. The 

 beds at Battery Point are found to dip at a less stoop 

 angle of 50° to G0° to the N.E. Thoy are full of Crinoidal 

 fragments with some Spirifers, and would seem to belong to 

 the base of the Mountain Limestone series. 



Skirting tlio shore of Wood Hill 15ay, wo soon conic to an 

 exposure of Lower Limestone Shales, where the beds are 

 folded into quickly succeeding cui'ves, the summits of tho 

 anticlinals being eaten into by denudation. To tho south, 

 of tliis exposure the Bryozoa Bed is again displayed. The 

 strike of the folded beds is E. by S. 



Still continuing to skirt the bay, witii tho isolated knoll 

 of Wood Hill to our loft (1j.), wc cross a triangular patch of 

 alluvial ground, between which and tlie Sovprn muds is a 

 beach-ridgo of Old lied pebbles. Near the charred remains 

 of tho Beach Hotel we find the Old lied Sandstone well 

 exposed. The strata show strong conglomeratic beds, witli 

 pebbles of opaque white quartz ; sandy beds, with excellent 

 examples of false bedding; and, where the wearing back of 

 t.lif^ cliff h:is exposed tho surface of irh(^ IkmIh, .■ibmuin/ut
