"Stop right there," it said. "We have got you covered."

It was followed by the whip-like crack of a pistol-shot, there was the louder jarring ring of a carbine or a farmer's rifle, and a confused din broke out. Men shouted and scuffled in the gloom, loaded beasts blundered among the trees and the undergrowth, while through it all there rose the detached beat of hoofs.

"One or two of them lit out, anyway," said the trooper. "Guess they'd slash the pack lariat, and get into the saddle when they'd let the whisky go. That sounds like one of the boys after them. Chancing a gallop, too. They'll break their necks certain, if they ride that way through the bluff."

He stopped a minute, and just then a faint silvery radiance swept athwart the birches as the moon shone down. It sparkled on the dropping smear of snow-sheeted trail, and the lad ran forward a pace or two fumbling with his carbine.

"Look out, Mr. Leland!" he shouted. "There are two of them riding slap down on us."

Two indistinct objects swept out of the shadows, and a moment later resolved themselves into men and galloping horses. They were thundering headlong down the sharply falling trail, and Leland felt his nerves tingle as he watched them. He was in a particularly unpleasant temper that night, and the prospect of an encounter stirred the half-frozen blood in him. He glanced over his shoulder, and saw the trooper standing a few paces away from him, and then fixed his gaze up the trail ahead. The horsemen were coming on at a mad gallop, taking their chances of a stumble, and he could see the powdery snow whirl about them like dust. Then they saw him standing grimly still in the middle of the trail, for one shouted a warning to the other, and the trooper cried aloud:

"Hold on! Pull up before we plug you," he said.

There was no answer. The riders were hard and fearless men, probably wanted by Montana sheriffs for things they had done during the cattle war, and they showed no sign of drawing bridle. One of them howled shrilly as he whirled a whip about his shoulders, and for a moment Leland saw him sway in the saddle with the beast stretched out beneath him.

Then there was a flash, and a detonation he scarcely heard, a cloud of smoke that floated up the trail, and man and horse came thundering down on him. He felt the jar of the Marlin rifle on his shoulder as he aimed at the flying form of a horse. In another moment the outlaw was almost upon him. Then in savage recklessness he leapt forward instead of back, with a hand that sought the bridle and an arm the rider's leg. His fingers closed on something—bridle, or saddle, or stirrup—and he clung with a stiffened grasp, while his feet were torn from under him and a rifle flashed.

Exactly what happened after that he did not know, but he was hurled forward, still clutching at something, with feet that scraped the snowy ice of the creek; and then there was a heavy crash, and what he held was torn away from him. He felt himself driven into a bank of snow, and lay there for perhaps a minute wondering vaguely if the life had all been smashed out of him, and listening to a sound of scuffling and floundering close by. Next he essayed to draw one of his feet up, and, to his astonishment, found that he had no great difficulty in accomplishing it. That done, he raised himself shakily, and, scrambling to one of the birches, leaned against it, gasping a little. A few seconds earlier he had been almost certain that he would never stand up again.
