Limestone, light colored and mag- 

 nesian representing the upper- 

 most course of quarry which in 

 many cases has been removed.. .60 inches 152 cm. 



Limestone of the second course. 

 Hard, massive, and very similar 

 to the overlying bed from which 

 it is distinguished only by differ- 

 ence in thickness. Both these 

 B. { courses contain a tabulate coral, 

 generally poorly preserved except 

 in one locality, to which refer- 

 ence will be made later 41 104 cm. 



Limestone. This is the lowest cour- 

 se generally quarried. Less mas- 

 sive than either of above, quite 

 often breaking into laminae 2 to 

 10 inches (5 to 25cm.) in thick- 

 ness 48 " 122 cm. 



In one portion of this quarry operations were at one 

 time continued below this, revealing the following: — 



C. 



D 



Shale, red and nodular in char- 

 acter. The individual nodules 

 are fairly hard, but the mass 

 does not form a consistent bed . . 15 inches, 38 cm. 



Limestone, yellowish in colour, 

 hard and porous, probably mag- 

 nesian. The pores are large, 

 resulting probably from weather- 

 ing out of fossils or other more 

 soluble content. Tabulate cor- 

 als and cephalopod remains occur 

 in this layer 31 " 79 cm. 



Limestone, similar to above, but 

 lower half is darker in colour, and 

 has much finer pores, uniformly 

 distributed. Forms the "free- 

 stone" of this level 41 " 104 cm.
