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 S. 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 L 20 feet broad and 20 feet deep ! The sides, as before, curv e 

 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. 



III. ERRATICS, MORAINES, KAMES, ETC. 



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 tying to the north-west of 

 Lake Rossignol in Queen's County, and along the county lines 

 separating Digby County from Shelburne and Yarmouth. Here, 

 over an extensive tract, including the so-called Blue Mountains,
