rock at which is a now abandoned limekiln. The rock here was burned 

 by Mr Philip Le Boutillier and from him I learn that the burning 

 has been only partly successful but at times a purer limestone has been 



brought to the kiln from the 

 outcrops at Cape Blanc, two 

 miles south. 



The rocks at this limekiln 

 are an undoubted part of those 

 at Cape Canon though the beds 

 are heavier limestones much 

 seamed with calcite veinules, 

 largely a limestone conglom- 

 erate. They have a thickness 

 of 200 feet. A single bed of 

 a similar conglomerate was 

 observed infolded in the schists 

 of Cape Canon. 



Just beneath these con- 

 glomerates on the south slope 

 are even bedded impure gray limestones and from detached blocks here 

 fossils have been obtained. There is some reason in regarding these 

 fossil-bearing blocks as not pertaining to this spot though concerning 

 this point I would not venture to be unqualified in my statement. These 

 fossils are : 



Plectambonites sericeus (Sowerfy) (very common) 

 Rafinesquina, a geniculated species 

 Leptaena rhoraboidalis {Wilckens) 

 Protozyga exigua Hall 

 Ambonychia sp. 



Ceraurus pleurexanthemus Green 



Though few in number, the species abound in individuals and the 

 assemblage clearly indicates a late stage of the Lower Siluric equivalent to 

 middle or upper Trenton age.
