His instructions were very few; he knew what to do. That was to ride back to the gulch, and select a good spot, one which combined two advantages, commanding a far-reaching view down the wild approach, while affording good cover and concealment for him.
He started at once, riding off and giving two good long earnest looks at the busy party placing their loads on the mules’ backs.
Then a turn amongst the rocks hid him from sight, and the boy felt his heart sink, in spite of the way in which he braced himself up for his task, for the gulch looked more and more dark and forbidding as he rode on, the sides closed in closer, it seemed, than they had been when he came, and as he strained his eyes forward along the trackless way, bush after bush and rock after rock in the distance sent his heart, as it were, with a bound to his throat, so nearly did his imagination make these objects approach the aspect of savage Indians riding slowly towards him.
But a second glance generally resolved them into what they were, fancy paintings, and he bit his lips fiercely with annoyance as he called himself coward and one quite unfit for such a task.
He had ridden onward for some time before he found a post that seemed in any way suitable, for the gulch turned and doubled and zigzagged here and there in a way that gave him sadly shortened views, and he was at last about to turn back to the best place he had passed, bad as it was, when he recognised a corner in front as being formed by a rock that he remembered seeing for long enough on their approach, one that never seemed to get any nearer, and to his joy when he now reached it he found everything he desired—command of the gulch for quite a mile, plenty of cover to hide him and his pony from the view of those who came along, and, what was very acceptable then, a tiny basin of pure cold water in which his mustang gladly plunged its muzzle for a long, deep drink.
Then with a sigh of relief the scout took up his position to watch for the coming danger, knowing as he did that he had only to draw back a few yards for the great elbow-like rock to cover his retreat so that he could hurry away with the warning of danger and give all time to seek the cells that they were to defend.
“They ought to have loaded up by now,” he said to himself, “and all has turned out splendidly, while perhaps after all the Indians may never find this deep, dark gulch. It was only by accident that we did.”
Chris had just comforted himself with this notion when a horrible thought assailed him. It was this—
All the way he came he had been keeping up a good lookout in front for the approaching danger, and had never once thought of looking up to right or left for some narrow side valley or gash by which the danger might suddenly descend into the narrow way.
The thought was so terrible that he turned cold and looked back, half-expecting to see a group of the bronze warriors in his rear; and then his too busy imagination pictured more, the whole band in fact riding down by the gash in the rocks that he ought to have seen, and stealthily coming on to surprise those whom it had been his duty to save.
