"How about keeping watch?" asked Ashton, when he returned with the cleansed dishes. "Shall I take first or second?" "Neither," answered Blake. "You will need all the sleep and rest you can get. Tomorrow may be a hard day. Turn in at once." "If you insist," acquiesced Ashton. "I still am rather weak and dizzy." He went to the tent and disappeared. Blake took the lantern and strolled across to the wagon, to look at the numerous articles brought by Gowan. He set the lantern over in the wagon bed on top of what seemed to be a heap of empty oat sacks, while he overhauled the load. It included three coils of rope of a hundred feet each, a keg of railroad spikes, two dozen picket-pins, two heavy hammers, a pick and shovel, and a crowbar. The last three articles had not been ordered by Blake. The puncher had brought them along, apparently with a hazy idea that the descent of the canyon would be something on the order of mining. There were also in the wagon two five-gallon kerosene cans to use in carrying water up the mountain, a sack of oats, Gowan's saddle, and two packsaddles. In shifting one of the packsaddles to get at the hammers, Blake knocked it against the sack on which the lantern had been set. The lantern suddenly fell over on its side. Blake reached in to pick it up, and perceived that the sack was rising in a mound. He caught up one of the hammers, and held it poised for a stroke. From the sack came a muffled rattle. The hammer descended in a smashing blow. The sack rose and fell as if something under it was squirming about convulsively. But to Blake's surprise it did not fall aside and disclose that which was making the violent movement. The squirming lessened. He grasped an outer corner of the sack and jerked it upward. It failed to flip into the air. The lower part sagged heavily. The squirmer was inside and--the mouth of the sack was tied fast. Blake looked at it thoughtfully. After some moments, he placed the sack where it had lain at first, and upset the keg of spikes on top of it. He then carefully examined Gowan's saddle; but it told him nothing. He shook his head doubtfully, and returned to camp. Going quietly around to Gowan, he set down the lantern close before the puncher's face and stopped to light a cigar. Gowan stirred restlessly and rolled half over, but did not open his eyes. Blake smoked his cigar, extinguished the lantern, and quietly stretched out on the edge of the sleeper's blankets. In a few moments he, too, was asleep. About two o'clock Gowan stirred and rolled over, pulling at his blankets. Instantly Blake was wide awake. The puncher mumbled, drew the blankets closer about him, and lay quiet. Blake went into the tent and dozed on his own blankets until roused by the chill of dawn. He went down for a plunge in the pool, and was dressed and back at the fireplace, cooking breakfast, when Gowan started up out of his heavy slumber.
