Men working on the prairie or in the bush of Canada are usually boarded by their employers at a weekly charge, and there were a good many of them engaged on the track. As a result of it, the iron shack was partly filled with provisions, and when Slaney and the trooper entered by the front they had seen a pile of cases and flour-bags apparently built up against one wall. It was, however, growing dark then, and neither of them had noticed that there was a narrow space behind the provisions which had been left to facilitate the entrance of the cook. Winthrop, it was clear, had slipped out through it in the darkness, and the shack had prevented either of the watchers from seeing him crawl away across the prairie. It occurred to Slaney that from the position of the tents it was scarcely likely he had got away quite unnoticed, but he had reasons for believing that it would be difficult to elicit any reliable information on that point from the man's comrades.

There was only one thing to be done, and that was to mount as soon as possible and endeavor to pick up the fugitive's trail; but when they reached the spot where they had left their horses there was no sign of them, and it was half an hour before the trooper came upon them some distance up the coulée. Slaney was quite convinced that neither of the beasts had succeeded in dragging the picket out of the ground unassisted, but this was a thing he could not prove; and when the cook had supplied them with a hastily prepared breakfast he and the trooper rode away across the prairie.

CHAPTER XVII
A COMPROMISE

Thorne was driving Alison home from Graham's Bluff one afternoon about a week after Winthrop's escape when a couple of horsemen became visible on the crest of a low rise. The girl glanced at them from under her white parasol, which shone dazzlingly in the fierce sunlight, and then fixed her eyes on her companion.

"They're coming this way, aren't they?" she asked.

"They seem to be," replied Thorne. "One of them looks like the corporal, and I shouldn't wonder if he wanted a word with me."

He saw the girl's slight start, but was not greatly flattered, as he could not be sure whether it resulted from concern on his behalf or mere annoyance. He knew what she thought of Winthrop.

"There's no cause for alarm," he added with a laugh. "I haven't done anything particularly unlawful for some time."

He had half expected Alison to explain that she was not alarmed at all, but she disappointed him, and he wondered whether there was any significance in this. He had already discovered that she did not invariably reveal exactly what she felt.
