His companion had noticed the ground already, and assented. There were no tracks anywhere to be seen over which winter had not come and gone since they had been made. Presently the trail wound into a sultry gulch that hemmed in the heat and seemed to draw down the sun’s rays more vertically. The sorrel horse chose this place to make a try for liberty. He suddenly whirled from the trail, dragging with him his less inventive fellow. Leaving the Virginian with the old mare, Balaam headed them off, for Pedro was quick, and they came jumping down the bank together, but swiftly crossed up on the other side, getting much higher before they could be reached. It was no place for this sort of game, as the sides of the ravine were ploughed with steep channels, broken with jutting knobs of rock, and impeded by short twisted pines that swung out from their roots horizontally over the pitch of the hill. The Virginian helped, but used his horse with more judgment, keeping as much on the level as possible, and endeavoring to anticipate the next turn of the runaways before they made it, while Balaam attempted to follow them close, wheeling short when they doubled, heavily beating up the face of the slope, veering again to come down to the point he had left, and whenever he felt Pedro begin to flag, driving his spurs into the horse and forcing him to keep up the pace. He had set out to overtake and capture on the side of the mountain these two animals who had been running wild for many weeks, and now carried no weight but themselves, and the futility of such work could not penetrate his obstinate and rising temper. He had made up his mind not to give in. The Virginian soon decided to move slowly along for the present, preventing the wild horses from passing down the gulch again, but otherwise saving his own animal from useless fatigue. He saw that Pedro was reeking wet, with mouth open, and constantly stumbling, though he galloped on. The cow-puncher kept the group in sight, driving the packhorse in front of him, and watching the tactics of the sorrel, who had now undoubtedly become the leader of the expedition, and was at the top of the gulch, in vain trying to find an outlet through its rocky rim to the levels above. He soon judged this to be no thoroughfare, and changing his plan, trotted down to the bottom and up the other side, gaining more and more; for in this new descent Pedro had fallen twice. Then the sorrel showed the cleverness of a genuinely vicious horse. The Virginian saw him stop and fall to kicking his companion with all the energy that a short rope would permit. The rope slipped, and both, unencumbered, reached the top and disappeared. Leaving the packhorse for Balaam, the Virginian started after them and came into a high tableland, beyond which the mountains began in earnest. The runaways were moving across toward these at an easy rate. He followed for a moment, then looking back, and seeing no
