Every moment it was increasing.
“Bejabers, Misther Frank, is there much more wather comin’?” cried Barney. “Shure if so, I’m thinkin’ we’d better be after getting out of here.”
“Right?” cried the young inventor, excitedly, “but where can it come from?”
He ran to an eminence near and from which a good view of the upper canyon could be had.
And there Frank beheld a thrilling sight.
At the upper end of the canyon was a large lake made by an accumulation of logs and debris across the source of the canyon.
Here half a score of men with axes and iron bars were engaged in breaking the dam so as to let the whole lake down into the gorge.
It would mean a flood of awful sort if they succeeded.
It would surely sweep the canyon clear, and the position of Barney was a most perilous one.
Frank saw this with horror.
