TABULATION AND DESCRIPTION OF NEW DATA 223 



at New Glasgow they are 85 feet and somewhat higher at Truro. At the 

 latter place and other stations on the Bay of Fiindy and its branches the 

 marine level is complicated by the probably large tidal range, even at the 

 time of deep submergence. At Truro some weak evidence of water work 

 was seen up to 100 feet, but excellent plains at 85 feet. The theoretical 

 level is taken as 90 feet. 



At Halifax the uplifted shore features are weak and rather uncertain, 

 and on account of continuous fog they were not sufficiently examined; 

 but the final adjustment of the isobases confirms the determination made 

 on the ground, about 60 feet. Weak evidences at about the same height 

 appear along Saint Margaret and Mahone bays. 



From Liverpool around to Yarmouth the coast is strewn with huge 

 granite blocks derived from the land on the northwest (plate 17). From 

 Yarmouth to Digby the shore was not seen, the railroad lying across the 

 interior, mostly in forest. At Digby and along the Annapolis Basin good 

 delta plains and shorelines are conspicuous and were estimated in height 

 up to 90 feet; but the maximum was not determined. According to the 

 isobases, the altitude of the summit level here should be about 100 feet. 

 The famous Annapolis Valley is filled with handsome gravel plains. The 

 railroad, passing northeast, drops to 27 feet at Bridgeton and then rises 

 steadily on the plains to 100 feet at Aylesford and to 138 feet at Berwick, 

 the summit of grade. Probably some allowance must be made in this 

 valley for the very high tides and storm waters forced across the col. The 

 map makes the marine plane here about 125 feet, in agreement v^^ith the 

 field conclusion. 



About the Minas Basin the land is low. Up the Kennetcook Eiver the 

 delta and stream plains in the narrow valley are excellently displayed. 

 The county of Cumberland, north of Cobequid highland, exhibits abun- 

 dant submergence features, and the same is true of all the coast of Cum- 

 berland Strait and George Bay, counties of Pictou and Antigonish. In 

 the district of Amherst and Springhill detrital plains are seen much above 

 the theoretic marine level. These are attributed to the smoothing work 

 of the extreme high tides which probably swept this area during the sub- 

 mergence. 



In the valley of West Eiver, between Antigonish and James Eiver sta- 

 tion, is a very heavy gravel kame area, and the aggraded plains rise from 

 about 15 feet at Antigonish to 235 feet in the 9^/2 miles to James Eiver, 

 giving a gradient of 23 feet per mile. 



East of Halifax the multitude of streams with flow direct to the At- 

 lantic should hold excellent and positive summit deltas, but the coast is 

 not easily accessible and is very wild away from the shore.
