But this incident meant to Jack that what he had dreaded most was actually happening.
The subterranean watercourse was narrowing.
Hardly had the thought flashed through his mind before he felt himself sucked by what seemed an invisible arm below the surface. At the same instant Ralph was torn from his arms, and both boys, submerged in a narrow part of the tunnel, were drawn through the dark tube at the speed of an express train.
"The end!" was the thought that flashed through Jack's mind as he felt that his worst apprehension had come true.
But it was not the end, for an instant later he was shot out of the terrible restriction of the narrow irrigation tube into brilliant, blinding sunlight.
"Why, this is a sort of scenic railway!" was the whimsical idea that sped across the boy's mind as he gazed about him. The current had ceased dashing him about, and he was floating in a large pool from which ramifications of sluiceways led in every direction. It was the main retaining basin of the irrigation works. Weakened though he was, Jack found no difficulty in swimming here, and, to his delight, not many feet from him Ralph was still struggling feebly for life. A few strokes brought the boy to his chum's side, and a few strokes more brought them both ashore.
They reached the shallow bank, and Jack laid Ralph down. As he did so, the other boy fainted in good earnest. As Jack bent over his chum he was startled to hear a voice above, and looking up, saw a man in irrigation boots, with a big shovel in his hand, gazing at them curiously.
"Say, are you real, or just what the ground grew?" demanded the stranger. "The advertisements of this land company say their land'll grow anything, but dear land of Goshen! I didn't know it grew boys. That's a crop I've no use for. I've four of my own, and——"
"We're real boys, have nothing to do with any land company, and don't want to, either, after our experience in their water tunnel; and if you can help me get my chum up on the bank and help me revive him, I'll be much obliged," rejoined Jack, all in one breath.
