He presently thought of his weapons, drawing them out and reloading them. They recalled the incident of the Red Dog, and for a long time his thoughts dwelt on it, straight, grim lines in his face.

He wondered what Betty would say when she heard of it. Would it affect her future relations with Taggart? His thoughts were still of Betty when the wagon careened out of the level and began to crawl up a slope that led through some hills. The trail grew hazardous, and the horses were forced to proceed slowly. It was near midnight when the wagon dipped into a little gully about a mile and a half from the ranchhouse. Calumet halted the horses at the bottom of the gully, allowing them to drink from the shallow stream that trickled on its way to meet the river which passed through the wood near the ranchhouse.

After the animals had drunk their fill he urged them on again, for he was weary of the ride and anxious to have it over with. It was a long pull, however, and the horses made hard work of it, so that when they reached the crest of the rise they halted of their own accord and stood with their legs braced, breathing heavily.

Calumet waited patiently. He was anxious to get to the Lazy Y, but his sympathy was with the horses. He rolled and lighted another cigarette, holding the match concealed in the palm of his hand so that the breeze might not extinguish it.

Sitting thus, a premonition of danger oppressed him with such force and suddenness that it caused him to throw himself quickly backward. At the exact instant that his back struck the lumber piled behind him he heard the sharp, vicious crack of a rifle, and a bullet thudded dully into one of the wooden stanchions of the wagon frame at the edge of the seat. Another report followed it quickly, and Calumet flung himself headlong toward the rear of the wagon, where he lay for a brief instant, alert, rigid, too full of rage for utterance.

But he was not too angry to think. The shots, he knew, had come from the left of the wagon. They had been too close for comfort, and whoever had shot at him was a good enough marksman, although, he thought, with a bitter grin, a trifle too slow of movement to do any damage to him.

His present position was precarious and he did not stay long in it. Close to the side of the wagon—the side opposite that from which the shots had come—was a shallow gully, deep enough to conceal himself in and fringed at the rear by several big boulders. It was an ideal position and Calumet did not hesitate to take advantage of it. Dropping from the rear of the wagon, he made a leap for the gully, landing in its bottom upon all fours. He heard a crash, and a bullet flattened itself against one of the rocks above his head.

"He ain't so slow, after all," he admitted grudgingly, referring to the concealed marksman.

He kneeled in the gully and looked cautiously over its edge. The wagon was directly in front of him; part of one of the rear wheels was in his line of vision. The horses were standing quietly, undisturbed by the shots. He resolved to keep them where they were, and, exercising the greatest care, he found a good-sized rock and stuck it under the front of the rear wheel nearest him, thus blocking the wagon against them should they become restless.

The moon was at his back, and he grinned with satisfaction as he noted that the rocks behind him threw a deep shadow into the gully. He could not help thinking that his enemy, whoever he was, had not made a happy selection of a spot for an ambuscade, for the moonlight's glare revealed every rock on the other side of the wagon, and the few trees in the wood behind the rocks were far too slender to provide shelter for a man of ordinary size. Calumet chuckled grimly as, with his head slightly above the edge of the gully and concealed behind the felloes of the wagon wheel, he made an examination of the rocks beyond the wagon.
