We propose now to go northward in the direction of our main 
glacial line, N. 40° W., to notice its Geology and to indicate the 
formations that have produced the drift material already referred 
to. From Halifax Harbour Mouth, a distance of 33 miles, 
(Mackinlays’ Map) we have the Lower Cambrian Formation 
with its Quartzites and Argillites and associated Granites, west 
side of the Harbour and Mount Uniacke. On our way we have 
passed through the County of Halifax and entered the County 
of Hants. We now enter the Carboniferous Formation with its 
Sandstones, Limestones and Gypsums. The Limestones are 
sometimes fossiliferous (Fauna) the Sandstones, &., having Flora. 
Passing through these 21 miles we reach the “Mines Basin,” 
Reaching the other side we have gone 18 miles. The Formation 
lying under the water is the Triassic. (New Red Sandstone.) 
At 12 miles distance we passed Blomidon with its Basalts and 
Amyegdaloids and Sandstones. On the north side of the Basin 
‘we have Partridge Island similarly constituted. We are now in 
Cumberland County at the junction of the Triassic with the 
Carboniferous Formation. Proceeding through Parrsboro’ we 
traverse its Carboniferous to a distance of 4 miles. We have 
reached the Cobequid Mountains with (a) its Upper Silurian 
Formation (metamorphic.) This is the band that contains the 
Londonderry Iron Mines, about 40 miles to the eastward. After 
going ten miles and a half we reach Crystalline, Metamor-
