74 NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK BAILEY. 



Plate V, accompanying this paper, represents the basaltic 

 structure as seen at Israel Cove, near the southern end of Petite 

 Passage. 



Some fine basaltic scenery, of which a sketch is given in 

 " Acadian Geology," is also to be seen on Briar Island, near 

 Westport, but in general the land here is lower and the features 

 less bold than about the Petite Passage. 



That so prominent a ridge as that of Digby Neck should 

 have been greatly affected by the conditions incidental to the 

 glacial period, would naturally be expected. These are, however, 

 shown rather in the evidences of enormous denudation than in 

 the production of new deposits. Portions of the ridge are, it is 

 true, somewhat deeply buried in boulder clay ; and boulders 

 (including in a few instances granitic and felsitic blocks which 

 must have come from the other side of the Bay of Fundy) are 

 scattered over all parts of its surface; but the occurrence in great 

 profusion of the characteristic rocks of the peninsula along the 

 southern side of St. Mary's Bay, and, though less abundantly, 

 over Yarmouth and Shelburne Counties, even to the Atlantic 

 seaboard, gives forcible illustration of the extent to which the 

 substance of the peninsula has been removed. 



The fact also that the* transverse valleys of Sandy Cove, 

 Petite Passage and Grand Passage, as well as others less con- 

 spicuous, are oblique to the peninsula arid almost exactty parallel 

 to each other, while their course corresponds with that of the 

 glacial striation of the district, goes far to favor the view that 

 they owe their origin, partly if not wholly, as has been suggested 

 in the case of Digby Gut, to the excavating action of glacial 

 streams. The occurrence of striations on the surface of the 

 basaltic columns in Israel Cove, and within a few feet of the 

 surface of the water, gives further probability to this view. 



MINERALS. 



The minerals of Digby Neck are the same as those found in 

 other parts of the North Mountain Range, but are less abundant 

 and less varied than in the section of the latter which lies east 

 of Digby Gut.
