NOVA SCOTIAN GEOLOGY—HONEYMAN, 29s 
5. Post Pliocene——The boulders of Amygdaloid in the drift 
eutting east of Acadia College, Wolfville, have already been re- 
ferred to. In the hollow over against the Gaspereaux Valley, at 
the junction of the Pre-carboniferous and Carboniferous strata. 
already noticed, the occurrence of similar boulders was so strilk- 
ing, that it appeared as if the rocks must be in situ. In the 
Gaspereaux Valley they were seen in sufficient abundance. | 
also discovered them at Greenfield on the Halfway River. There 
is no doubt but that they are to be found in intermediate drift, 
if looked for. Mr. Ellershousen informed me that they occurred 
in the drift at Ardoise. They are to be found all along in the 
drift cuttings of the Windsor Railway. In previous paper, “On 
the Superficial Geology of Halifax Co,’—Transactions, 1876-7— 
| I pointed them out in great abundance in the drift cuttings be- 
tween the Beaver Bank Station and the Windsor Junction. At 
the Windsor Junction they are found in abundance at the drift. 
They occur in the drift at Bedford, in the Navy Island, in 
Bedford Basin, in the drift cuttings at Richmond, in the Citadel 
Hill, in the Dartmouth drift beds, in George’s Island, MeNab’s 
Island, Point Pleasant; apparently at Ketch Harbor, Sambro, 
Devil’s Island, and along the Eastern shore as far as Three 
Fathom Harbor. Thus notably has the Blomidon area of rocks. 
suffered from the exactions of post trappean and post pliocene 
agencies. Its height must therefore have been considerably 
greater than we now find it. The sandstone of the valley must 
have risen to a greater elevation than at present, forming a 
highway for the transit of the mountain debris, the valley 
having been subsequently formed, and the pathway destroyedt 
The remains of these sandstones on the sides of the Trappean 
area, and the sections on the shore, running almost on a level 
with the Trap elevation, as well as the elevation of the drift on 
the south side of the valley, tend to prove the former existence 
of this highway. If Minas Basin then existed, its boundaries 
must have differed greatly from those now apparent. The 
creeks and sections of new red Sandstone now extending be- 
tween Blomidon and Grand Pre were unformed, and the 
Kstuary of the Avon unknown. These were doubtless exten-
