e night. He also knew why he and his fellows had been cooped up
in the cave in the rock in which they lived, all that day, and had not
been allowed to come down and do any work.

They were lying huddled in their little cave, feeling very hungry and
miserable, and whispering together,--for if they spoke out or made any
noise, one of the men below would be likely to fire a load of shot at
them,--when suddenly a strange thing happened.

They heard a great roar like a thousand bulls, which came from the
higher part of the ravine, and peeping out, they saw what seemed like a
wall of rock stretching across the little valley. But in a second they
saw it was not rock--it was water, and before they could take two breaths
it had reached them. Then it passed on, and they saw only the surface of
a furious and raging stream, the waves curling and dashing over each

which always ran at the bottom of the ravine, and which now seemed not
very much bigger than it had been that morning.

But the little brook was all there was in the ravine, except the bare
rocks, wet and glistening. There were no huts, no Rackbirds, nothing.
Even the vines and bushes which had been growing up the sides of the
stream were all gone. Not a weed, not a stick, not a clod of earth, was
left--nothing but a great, rocky ravine, washed bare and clean.

Edna Markham stepped suddenly forward and seized the captain by the arm.
"It was the lake," she cried. "The lake swept down that ravine!"

"Yes," said the captain, "it must have been. But listen--let us hear
more. Go on," he said to Cheditafa, who proceeded to tell how he and his
companions looked o
