GLACIAL TRANSPORTATION—HONEYMAN. 35 
subsequently of the Archean rocks of Nova Scotia and Cape 
Breton, or elsewhere, I have not found another rock like it. On 
re-examining the shore where the boulders lay, I observed similar 
-boulders rolling down the bank out of the drift which overlies 
the gypsums and limestones. I consequently concluded that the 
boulders had been derived from the Archean rock on Northum- 
berland Strait,—having been transported a distance of 10 miles. 
A line drawn on the Admiralty Chart from the position of the 
rock to that of the boulders on the shore, runs S. 20 E., N. 20 
W., magnetic. This is parallel to the line of Blomidon amygda- 
loid transportation. This is a striking coincidence. It is also 
parallel to the intermediate glacial lines of Gay’s River road and 
the Gore. (Acadian Geology Table.) 
Further west in the Arisaig Township, we have the jaspi- 
deous rocks of Frenchman’s Barn and of Arisaig Pier, trans- 
ported southwardly ; massive boulders being found landed on 
the higher grounds. 
ADMIRALTY CHART LINES. 
My working chart shows the Strait of Canseau running 
parallel with the extension of the Northumberland Strait and 
Morristown (Antigonish) Archean transportation course, and all 
the Atlantic coast harbours of Nova Scotia, as far west as Ship 
harbour, approximately parallel. From Ship. harbour to Halifax 
harbour the harbours follow approximately the course of lines 
made by local glaciers. (See preceding Papers. Trans. 1875-6, 
and 1881. S. and £.) 
Halifax harbour and the estuary of the Avon are in the line 
of the Blomidon and Halifax glacier, which has transported the 
triassic amygdaloids. The Archean transportation glacier con- 
verging on Bedford Basin. The Blomidon Bieiatich, lines 
extended N. W., pass through the depression ae the Cobequid 
mountains,

‘As I have noticed in other papers on general geology, 
triassic amygdaloids, from North Mountain, a continuation of 
Blomidon, were collected by myself in the drift cuttings of the
