The destructive cloudbursts that sometimes break with cyclonic suddenness in the West are as short-lived as they are violent. It is impossible that it should be otherwise, for they consist simply of a sudden precipitation or fall of an enormous mass of water from the skies, which naturally hunts with the utmost swiftness for the lowest level. That found, the frightful flurry is speedily over.

It was with unspeakable relief that George and Victor Shelton finally saw that the torrent had ceased to climb the slope. A few minutes later they uttered a prayer of thankfulness when they perceived that the volume was diminishing and the margin of the torrent was steadily retreating down the incline again. All danger for the time was over.

“How is it that Mul-tal-la is on the other side of the valley?” asked George.

“I don’t know. He left camp soon after you lay down, telling me he wouldn’t be gone long. He must have had some business or pleasure to look after. I thought maybe he had gone to make a call on some of his people. It was lucky for us that he saw what was coming and gave us warning in time.”


CHAPTER XIV
SHOSHONE CALLERS.

THE torrent loosed by the cloudburst steadily grew less and less, and at the end of two hours the stream had shrunk almost to its former insignificant proportions. The boys might have returned to the site of the camp and remained in safety until morning, but they had no inclination to do so. Indeed, it would have been hard to identify the spot, for the grass everywhere lay as flat as if a mountainous roller had pressed it down. Here and there could be dimly seen the trees, some shorn of their limbs, so that they were like so many logs, twisted and pronged stumps and, strange as it may seem, boulders weighing in some instances several tons, lay where they had been flung by the raging waters.

When no doubt remained that the danger was over, the bridles, saddles and packs were again placed on the ground and the horses set free. It was impossible to start another fire, since no fuel was obtainable, and the brothers sat on the ground, wrapped in their blankets and near enough to feel their mutual warmth. The shock through which they had passed drove away all inclination to sleep, and they talked and speculated until the gray light of morning glowed in the east.

Naturally they looked for the return of the Blackfoot, who had left them the night before. The valley, strewn with the debris of the flood, stretched out before them, and they gazed up and down its winding extent and across to the corresponding slope, but without seeing man or animal. Not the least striking feature of the scene was the carcasses of several elks and antelopes, while in the distance was recognized the brown, bulky body of an immense bison or buffalo. These various animals, doubtless with others that were not visible, had paid the penalty of being caught in the irrestrainable rush of the torrent.

That Mul-tal-la had met with any mishap was impossible, for it was he who discovered the nature of the peril before the brothers knew of it. The same recourse was at his command, for all he had to do was to make for the higher land, where he would be beyond reach of the wrathful waters.
