Highgate Centre, Friday Sep. 22-1922 Started in the gorge of the Minisquoi River, due on the north side of the river. One sees that the dol. at the top of the Section is decidedly an intertr. emyl. Further that there is one apparent contact with the Highgate series. From here upwards in section, and up the river the section is as follows: Basal impure li. filtering close into intert. emyl. below. About one foot thick. 1/2 ft The banded li, seen in the railway cut. 5 feet. It is here in two beds, Lamination equal. See the sample. Intertwined dark blue thinnes of li with darker to black lengy shells. Beds as a rule one and three eighths long. 21 feet. One zone of laminated dull blue li., like the zone below bright thin blue li (1/2 to 1") interbedded. 5 feet. Thin bedded dark blue li. 1 4 Laminated li. as before 1/2 4 Thin bedded li., laminated beds, and intert emyl., with very small fossils. This emyl. is the same thing as the one seen on much one-half miles to the south of Canadian bridge, in the Doravton emplacements. At Highgate this emyl. swells to about one foot in thickness, but at the north it is several foot thick. About 60' Dark blue shale limestone emyl. slightly ochreous. The li., fossils are are small 1-2 wide though some are 4 wide and may occur. Total thickness about 5'6"
