locally known as Crow’s Neck Point. The rocks here are mica- 
schists, conspicuously studded with staurolitic crystals, as well as 
with irregular knobs or blotches, (some 6 x 3 or 4 inches in 
size,) which are in part at least half-formed crystals of andalusite. 
The rocks are massive but distinctly bedded, with a 8. W. dip of 
20°; and at right angles to this dip runs a trough or gully, 
similar in character and doubtless in origin also, to that of 
Lockeport Island described above, but in this instance not less 
than 20 feet broad and 20 feet deep! The sides, as before, curve 
regularly to the axis, and are everywhere smoothed and striated 
along lines parallel to the latter. : 
It is to be regretted that the writer, at the time of his visit 
to this locality, was unprovided with a camera. A view of this 
trough would, however, be less satisfactory than that of Locke- 
port Island, as in this instance the trough is in part occupied 
by a large boulder (possibly concerned in its origination), 
which somewhat obscures the prospect. Other troughs of less 
magnitude, but yet of unusual size, are found in the same 
neighbourhood.

Nova Scotia presents, almost everywhere, abundant oppor- 
tunities for the study of surface geology, more particularly as 
dependant upon the ice-movements and probable general glacia- 
tion of the Pleistocene Era ; but nowhere are such opportunities 
more forcibly pressed upon one’s attention than in the south- 
western counties. Some of the facts there exhibited have 
already been made the subject of comment by the writer, as well 
as by others, in the Proceedings of the Institute. It is not the 
intention of this paper to discuss them further here, but only to 
direct attention to a few localities in which they are especially 
noticeable. 
Boulders.—Of boulder-strewn districts probably none is more 
remarkable than that of the tract lying to the north-west of 
Lake Rossignol in Queen’s County, and along the ccunty lines 
separating Digby County from Shelburne and Yarmouth. Here, 
over an extensive tract, including the so-called blue Mountains,
