Geological Map of Newfoundland, 1919.
James Howley's 1919 geological map of Newfoundland showing, in addition to the geological features of the island, William Cormack's 1822 traverse and the extent of the railroad, the telegraph line and the 1875 railway survey.

The blue sections of the telegraph line were submarine cables. The one in Trinity Bay, going north-east, was the transatlantic cable, while the one in Placentia Bay, going south-west, was the line joining Newfoundland to St. Pierre and then Nova Scotia.
