He heard the click of iron-shod hoofs on stone, the coarse laughter of men, and then voices gradually dying away. Long moments passed. Then he rose. The rustlers were riding into a canyon. Their horses were tired, and they had several pack animals; evidently they had traveled far. Venters doubted that they were the rustlers who had driven the red herd. Olding's band had split. Venters watched these horsemen disappear under a bold canyon wall.

The rustlers had come from the northwest side of the oval.

Venters kept a steady gaze in that direction, hoping, if there were more, to see from what canyon they rode. A quarter of an hour went by. Reward for his vigilance came when he descried three more mounted men, far over to the north. But out of what canyon they had ridden it was too late to tell. He watched the three ride across the oval and round the jutting red corner where the others had gone.

"Up that canyon!" exclaimed Venters. "Oldring's den! I've found it!"

A knotty point for Venters was the fact that the cattle tracks all pointed west. The broad trail came from the direction of the canyon into which the rustlers had ridden, and undoubtedly the cattle had been driven out of it across the oval. There were no tracks pointing the other way. It had been in his mind that Oldring had driven the red herd toward the rendezvous, and not from it. Where did that broad trail come down into the pass, and where did it lead? Venters knew he wasted time in pondering the question, but it held a fascination not easily dispelled. For many years Oldring's mysterious entrance and exit to Deception Pass had been all-absorbing topics to sage-riders.

All at once the dog put an end to Venters's pondering. Ring sniffed the air, turned slowly in his tracks with a whine, and then growled. Venters wheeled. Two horsemen were within a hundred yards, coming straight at him. One, lagging behind the other, was Oldring's Masked Rider.

Venters cunningly sank, slowly trying to merge into sage-brush.

But, guarded as his action was, the first horse detected it. He stopped short, snorted, and shot up his ears. The rustler bent forward, as if keenly peering ahead. Then, with a swift sweep, he jerked a gun from its sheath and fired.

The bullet zipped through the sage-brush. Flying bits of wood struck Venters, and the hot, stinging pain seemed to lift him in one leap. Like a flash the blue barrel of his rifle gleamed level and he shot once--twice.

The foremost rustler dropped his weapon and toppled from his saddle, to fall with his foot catching in a stirrup. The horse snorted wildly and plunged away, dragging the rustler through the sage.
