It was getting dark, and a keen wind blew across the ragged pines beside the track, when Jake Foster walked up and down the station at Gardner's Crossing in North Ontario. Winter was moving southwards fast across the wilderness that rolled back to Hudson's Bay, silencing the brawling rivers and calming the stormy lakes, but the frost had scarcely touched the sheltered valley yet and the roar of a rapid throbbed among the trees. The sky had the crystal clearness that is often seen in northern Canada, but a long trail of smoke stretched above the town, and the fumes of soft coal mingled with the aromatic smell of the pines. Gardner's Crossing stood, an outpost of advancing industry, on the edge of the lonely woods.
