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 and almost exactly 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.
