"It sounds strange," commented Nevis. "Can you remember when it was?"

The conductor contrived to do so, and Nevis was not astonished when he heard the date. He decided that it would be wise to compare his conclusion with any views his companion might have about the matter.

"It's possible it was only one of the boys stealing a ride," he suggested.

"In that case he needn't have been so scared of Bill," was the answer. "It's most unlikely he'd have got out on the prairie after him. Strikes me the man was mighty anxious nobody should see him. Anyway, I thought no more about the thing, and only remembered it to-night."

Just then the scream of a whistle came ringing up the track, and the conductor pointed to a fan-shaped blaze of brightness which swept up out of the prairie.

"The express; I'll have to get along. We'll be off in two or three minutes now."

Nevis lighted a cigar as soon as he was left alone, and by the time the great express had flashed by with a clash and clatter he felt convinced that Corporal Slaney had erred in assuming that Winthrop had escaped across the frontier. Having arrived at this decision, he strolled back into the lighted car as the train crept out across the switches on to the waste of prairie. He had now something to act upon.

In the meanwhile, a weary man, dressed in somewhat ragged duck, sat one evening outside a tent pitched in the hollow of a prairie coulée, with a letter in his hand. His attitude was suggestive of dejection, but he clenched the paper in hard, brown fingers, and there was an ominous look in his weather-darkened face. It was careworn, though he was young, and his general appearance and expression seemed to indicate that he was a simple man who had borne a burden too heavy for him, until at last he had revolted in desperation against the intolerable load.

A new branch line crept along the side of the shallow coulée, which wound deviously across the great white sea of grass, and the trestles of a half-finished bridge rose, a gaunt skeleton of timber, above the creek that flowed through the valley. A cluster of tents and a galvanized iron shack, with a funnel projecting above it, crowned the crest of a neighboring ridge, and a murmur of voices and laughter rose faintly from the groups of men who lay about them. Winthrop, however, had pitched his camp a little distance from the others, so as to be nearer his work, which consisted in removing the soil from the side of the coulée to make room for the road-bed. He had obtained a team from a neighboring rancher, and a satisfactory rate of payment from the railroad contractor. Indeed, during the last few weeks he had almost fancied that he was at last leaving his troubles behind him, and then that afternoon another blow had suddenly fallen. The letter from Lucy Calvert contained the disturbing news that Nevis, who seemed to have discovered that he had not left Canada, was still in pursuit of him.

Presently two of his comrades from the camp strolled up to his tent and stretched themselves out on the harsh, white grass in front of it. They were attired as he was, and they had toiled hard under a scorching sun all day handling heavy rails, but one was a man of excellent education, and the other had owned a wheat farm until the frost had reaped his crop and ruined him.
