"A one-man dog—never anything else."
Half a dozen times during the day Peter had found the scent of Nada and Roger where they had come ashore, and from this night on he associated Breault as a necessary agent in his search for them. And with Breault he went, instinctively guessing the truth.
The next day they found where Nada and McKay had abandoned the canoe, and had struck south through the wilderness. This pleased Breault, who was tired of his poling. This third night there was a new moon, and something about it stirred in Peter an impulse to run ahead and overtake those he was seeking. But a still strong instinct held him to Breault.
Tonight Breault slept like a dead man on his cedar boughs. He was up and had a fire built an hour before dawn, and with the first gray streaking of day was on the trail again. He made no further effort to follow signs of the pursued, for that was a hopeless task. But he knew how McKay was heading, and he traveled swiftly, figuring to cover twice the distance that Nada might travel in the same given time. It was three o'clock in the afternoon when he came to a great ridge, and on its highest pinnacle he stopped.
Peter had grown restless again, and a little more suspicious of Breault. He was not afraid of him, but all that day he had found no scent of Nada or Jolly Roger, and slowly the conviction was impinging itself upon him that he should seek for himself in the wilderness.
Breault saw this restlessness, and understood it.
"I'll keep my eye on the dog," he thought. "He has a nose, and an uncanny sixth sense, and I haven't either. He will bear watching. I believe McKay and the girl cannot be far away. Possibly they have traveled more slowly than I thought, and haven't passed this ridge; or it may be they are down there, in the plain. If so I should catch sign of smoke or fire—in time."
For an hour he kept watch over the plain through his binoculars, seeking for a wisp of smoke that might rise at any time over the treetops. He did not lose sight of Peter, questing out in widening circles below him. And then, quite unexpectedly, something happened. In the edge of a tiny meadow an eighth of a mile away Peter was acting strangely. He was nosing the ground, gulping the wind, twisting eagerly back and forth. Then he set out, steadily and with unmistakable decision, south and west.
In a flash Breault was on his feet, had caught up his pack, and was running for the meadow. And there he found something in the velvety softness of the earth which brought a grim smile to his thin lips as he, too, set out south and west.
The scent he had found, hours old, drew Peter on until in the edge of the dusk of evening it brought him to a foot-worn trail leading to the Hudson's Bay Company post many miles south. In this path, beaten by the feet of generations of forest dwellers, the hard heels of McKay's boots had made their imprint, and after this the scent was clearer under Peter's nose. But with forest-bred caution he still traveled slowly, though his blood was burning like a pitch-fed fire in his veins. Almost as swiftly followed Breault behind him.
