GLACIAL DISTRIBUTION IN CANADA.

1. Triassic Amygdaloids (A) and Carboniferous Boulders.— 
The author's investigations of glacial distribution in Canada began 
in 1873. On the beach at Cow Bay, east of Halifax Harbour, 
Nova Scotia, abundance of amygdaloid boulders were seen. 
These were at once referred to Cape Blomidon, whose rocks are 
Triassic basalts, amygdaloids, &e. Blomidon, or some part of its 
rock extension to Five Islands, N. E., and Brier Island, is the only 
- series of rocks in Eastern Canada which could produce these 
boulders. Red Head, on the east side of Cow Bay, was seen to be 
the secondary source of the boulders. From this bluff of drift 
large and small amygdaloid boulders had just fallen. Here an 
agate was found, and specimens of Blomidon zeolites. Great 
masses of Cambrian quartzites had recently fallen, and were still 
imbedded in drift. These were strikingly grooved and striated on 
varying sides. Rock surfaces had also been observed on our way 
showing glaciation. Action and reaction were thus suggested. 
A copy of the Admiralty Chart, on which Blomidon and Halifax 
both appear, was procured. A very fine and extensive glaciated 
expanse of Cambrian argillites at Pleasant Park, Halifax Harbour, 
was located on this map. The direction of the glaciation and 
grooves, 8. 20 E., N. 20 W., was extended, and found to pass in 
front of Blomidon. Deep grooves were seen having a south-east 
termination, where the graver had evidently been fractured by 
coming in contact with hard edges of tilted and crumpled strata, 
the grooves terminating in small st77@, running in different direc- 
tions and disappearing. These show that the glaciating agency 
had evidently come from the N. W., the direction of Blomidon.
