“She was pretty,” replied Philip, “so pretty that I brought her picture along for my collection at home.” He looked about for McGill. “Where's the doctor?”

Falkner's face was very white as he explained what had happened during the other's absence.

“He said that he would camp early this afternoon so that you could overtake them,” he finished after he had described the capture and the doctor's departure. “The doctor thought you would want to lose no time in getting the prisoners to Fort Smith, and that he could get a good start before night. To-morrow or the next day I am going to follow with the other team. I'd go with you if he hadn't commanded me to remain here and nurse my head for another twenty-four hours.”

Philip shrugged his shoulders, and the two had little to say as they ate their dinners. After an hour's rest he prepared a light pack and took up the doctor's trail. Inwardly he rankled at the unusual hand which the little professor was playing in leaving Pierre's cabin with the prisoners, and yet he was confident that McGill would wait for him. Mile after mile he traveled down the creek. At dusk there was no sign of his new friend. Just before dark he climbed a dead stub at the summit of a high ridge and half a dozen miles of the unbroken barren stretched out before his eyes.

At six o'clock he stopped to cook some tea and warm his meat and bannock. After that he traveled until ten, then built a big fire and gave up the pursuit until morning. At dawn he started again, and not until the forenoon was half gone did he find where the doctor had stopped to camp.

The ashes of his fire were still warm beneath and the snow was trampled hard around them. In the north the clouds were piling up, betokening a storm such as it was not well for a man in Philip's condition of fatigue to face. Already some flavor of the approaching blizzard was carried to him on the wind.

So he hurried on. Fortunately the storm died away after an hour or two of fierce wind. Still he did not come up with McGill, and he camped again for the night, cursing the little professor who was racing on ahead of him. It was noon of the following day when he came in sight of the few log cabins at Fort Smith, situated in a treeless and snow-smothered sweep of the plain on the other side of the Slave. He crossed the river and hurried past the row of buildings that led to post headquarters. In front of the company office were gathered a little crowd of men, women and children. He pushed his way through and stopped at the bottom of the three log steps which led up to the door.

At the top was Professor McGill, coming out. His face was a puzzle. His eyes had in them a stony stare as he gazed down at Philip. Then he descended slowly, like one moving in a dream. “Good Heavens,” he said huskily, and only for Philip's ears, “do you know what I've done, Phil?”

“What?” demanded Philip.

The doctor came down to the last step.
