Although it was eleven o'clock, Aldous proceeded in the direction of the engineers' camp, still another quarter of a mile deeper in the bush.

He was restless.

He did not feel that he could sleep that night.

The engineers' camp he expected to find in darkness, and he was surprised when he saw a light burning brightly in Keller's cabin.
Keller was the assistant divisional engineer, and they had become good friends.

It was Keller who had set the first surveyor's line at Tete Jaune, and it was he who had reported it as the strategic point from which to push forward the fight against mountain and wilderness, both by river and rail.
He was, in a way, accountable for the existence of Tete Jaune just where it did exist, and he knew more about it than any other man in the employ of the Grand Trunk Pacific.
