GEOLOGICAL NOTES—HONEYMAN. 169 
noble profile ; proceeding, we viewed its triassic sections onward 
to Grand Pre, without difficulty. These sections represent the 
triassic formation of Cornwallis and Annapolis Valley. From 
the occurrence of the same formation on either side of the Basin, 
and to the eastward, as well as from the sections just referred 
to, we can safely infer that this formation extended, or yet ex- 
tends, from Parrsboro’ to Grand Pre,—a distance of 15 miles. 
The sections on the shore may therefore be added to our section. 
Approaching the estuary of the Avon, attention was directed to 
the interesting section of lower carboniferous strata called Hor- 
ton Bluff. Great outcrops of gypsum were observed on the right, 
and Cheverie triassic and lower carboniferous on the left. 
WINDSOR. 
Reaching Windsor we examined the interesting lower earbo- 
niferous section above the old Avon Bridge. Attention was first 
‘directed to the fossiliferous limestones, and the outcropping 
gypsum. Here very fine masses of selenite were found. Dr. 
Blanford observed the abundance of trappean boulders, and 
supposed that there must be a dyke in the neighborhood. Being 
assured that these amygdaloidal and otherwise were transported, 
he regarded Partridge Island as the source of supply. The 
abundance of associated boulders of crystalline rocks confirms 
the supposition. I will give the reason why. 
I had not examined these since I commenced my investigations 
in glacial transportation. I did not remember of the occurrence 
of any other than amygdaloid boulders. I had observed amyg- 
daloid at Blomidon, and had referred the amygdaloids in the 
drift of Halifax, &e., to Blomidon. 
The boulders of other crystalline rocks, sueh as syenites, dior- 
ites, &e., now observed at the Avon section, associated with the 
amygdaloids, basalts, and other trappean rocks, shew transporta- 
tion from the Cobequid Mountains, beyond Parrsboro’. Partridge 
{sland, being in their course, could not escape a levy any more 
than Blomidon, so that we may consider both as sources of sup- 
ply of amygdaloid and other trappean boulders. The glacier 
may thus be credited with facilitating the construction of the
