"I believe so," said Urmston, who felt a bit uneasy.

The stranger moved his hand a trifle, so that the butt of a pistol appeared above the edge of the holster.

"Then walk straight in front of you, through the bluff, and out on to the prairie," he said. "If you turn round, or come back in the next ten minutes, you're going to have trouble with my partner, who is watching you."

Urmston did not move at once. He did not think this visit promised anything particularly pleasant to Leland, but that was, after all, not his affair. Still, though he was not expecting either of them just then, there was a chance that Carrie or Mrs. Annersly might enter the bluff. He had no reason to suppose that the stranger would cause them any annoyance if they did, but the man's appearance was far from prepossessing.

"Well," said the latter sharply, "what in the name of thunder are you stopping for? Hump yourself before you're sorry."

Urmston saw the pistol slide almost out of the holster, and the man's hand move on the bridle. The gestures were suggestive, and he did as he was bidden. Carrie, he decided, had not come out yet, or he would have seen her. He did not stop until rather more than the prescribed ten minutes had expired, and then found himself well out in the silent prairie. It was almost dark now, but he thought he saw a dim object moving down the edge of the wheat, and that he could hear the muffled beat of hoofs. There was only one horse, however, and he realised that the part he had played had, perhaps, not been an altogether brilliant one. On the whole, he fancied, it would be advisable to say nothing about it. He went back through the bluff, and came upon Carrie moving across the space of dusty grass between it and the house.

"Do you know who it was that rode through the bluff a little while ago?" she asked.

"No," said Urmston, as carelessly as he could, "I certainly do not."

Carrie, so far as he could make out, appeared a trifle astonished. "Well," she said, "I thought you must have met the man. I saw him come out and ride towards the house, but didn't seem to recognise him. Still, I daresay he was one of our visitors' cattle boys."

"I scarcely think it's worth worrying about," said Urmston, reflectively. "For one thing, it's too beautiful a night to waste in thinking about a Canadian stock-rider. One would hardly imagine any of them are sufficiently interesting to warrant it."
