"I should say so!" gasped Dick. "It all happened so suddenly that I don't know yet what it was all about."
"The stream suddenly started flowing again," spoke Bud. "That's all there was to it. Must have been dammed up some place, and suddenly released. It's still rising, too," he added, as he leaned forward and held the lantern down over the ledge where he and his cousins had taken refuge.
"Rising?" sharply inquired Nort, and there was a tone of anxiety in his voice.
"Yes," remarked Bud, as he swung the lantern to and fro. "We didn't get up here any too soon, fellows! Look, the water would be up to our waists down there now, in the most shallow place, and it's got speed like one of Christy Mathewson's curves!"
His cousins could see that he had not exaggerated the matter. The waters were rising. Inch by inch, and foot by foot, the flood was approaching the crest. Where the boy ranchers had sat in the almost dry bed of the stream, to eat their lunch, there was now a mad race of swirling waters. Where they had stood, before climbing up to the ledge of safety, there was now three feet depth of water. And, as Bud had said, it was flowing along so swiftly, like the stream which turns a mill-wheel, that the boys could hardly have been able to keep their feet had they been down in the current, or even on the weakest edge of it.
But, as they were, they were safe for the time being. How long that would be the case none could tell. They could see, in the gleam of the one lantern saved in the mad rush, that the stream was coursing along as it had never coursed before.
"There must be a powerful lot of water coming out of the reservoir pipe," Nort remarked.
"Biggest ever, with all this water behind forcing it out," agreed Bud. "I hope the pipe holds."
"It isn't as if the pipe were the only outlet," said Dick. "You know the water can flow out of the tunnel above, and on either side of the conduit."
"Yes," agreed Bud, "and dad had it put in that way on purpose, so if ever a big flood did come, the tunnel could relieve itself without ripping away the pipe and reservoir. There's a sort of spillway at one side of the reservoir, you know."
