"I don't doubt that. He and his friend Holt are great little explainers."

In spite of his bitterness Sheba felt a change in him. She seemed to have a glimpse of his turbid soul engaged in battle. He turned away without shaking hands, but it struck her that he was not implacable.

While they were at luncheon half a dozen pack-mules laden with supplies for a telephone construction line outfit had passed. Their small, sharp-shod hoofs had punched sink-holes in the trail at every step. Instead of a smooth bottom the dogs found a slushy bog cut to pieces.

At the end of an hour of wallowing Macdonald called a halt.

"There is a cutoff just below here. It will save us nearly two miles, but we'll have to break trail. Swing to the right just below the big willow," he told Elliot. "I'll join you presently and relieve you on the job. But first Miss O'Neill and I are going for a little side trip."

All three of them looked at him in sharp surprise. Gordon opened his lips to answer and closed them again without speaking. Sheba had flashed a warning to him.

"I hope this trip isn't very far off the trail," she said quietly. "I'm just a wee bit tired."

"It's not far," the mine-owner said curtly.

He was busy unpacking his sled. Presently he found the dog moccasins for which he had been looking, repacked his sled, and fitted the shoes to the bleeding feet of the team leader. Elliot, suspicious and uncertain what to do, watched him at work, but at a signal from Sheba turned reluctantly away and drove down to the cutoff.

Macdonald turned his dogs out of the trail and followed a little ridge for perhaps a quarter of a mile. Sheba trudged behind him. She was full of wonder at what he meant to do, but she asked no questions. Some wise instinct was telling her to do exactly as he said.
