vicinity. It some instances it resembles the triassic sandstone, 

 but differs from it in containing no calcium carbonate. I have 

 traced this formation to within a short distance of the shale 

 but have not been able to observe the junction of the two. Its 

 age has not been accurately determined, but it may be sub- 

 carboniferous. 



EVIDENCES OF GLACIATION. 



Drift material from the North Mountain abounds on the 

 South Mountain, being especially plentiful in the gulches and 

 beds of brooks. This is mainly Amygdaloidal trap, which, not- 

 withstanding its tendency to decompose through weathering, is 

 found in somewhat large masses. In Wolfville, it is found in 

 the soil to a considerable depth, especially along the line of a 

 former beach. I have also found small boulders of syenite and 

 diorite, which must have come from the Cobequid Mountains, as 

 they resemble the rocks found in that range, and are unlike any 

 country rock I have seen on this side of the Minas Basin. 



STRLE. 



On the summit of the ridge south of Wolfville, in the hard, 

 fine-grained shale exposed on the side of the highway, parallel 

 markings may be seen in different places, evidently glacial 

 striae. I have also observed coarse markings on a freshly 

 exposed surface of Wickwire stone. These scorings all trend in 

 a south-easterly direction. 



EVIDENCES OF ELEVATION AND SUBSIDENCE. 



The encrinites found on New Canaan mountain indicate that 

 that formation was at one time covered by the sea, but its 

 present altitude is probably due to the upthrust of the mountain 

 range as distinguished from elevation over large areas. There 

 is good evidence, however, that the sea was at one time nearly 

 50 feet higher than at present in an old beach formation, extend- 

 ing along the line of Acadia Street, parallel to the present water 

 frontage. This, wherever dug into, presents a similar structure 

 of rounded stones, evidently well worn by attrition. Imme- 

 diately to the south of this, and at a higher elevation, is a
