The face of the dam on that part slowly settled down into a vast U.

Then the waters came through, leaping--a solid face of water such as no man may comprehend.
An instant, and the canyon below the dam was fifty feet deep with a substance which seemed not water, but a mass of shrieking and screaming demons set loose under the name of no known element.

There came a vast roar, but with it a number of smaller sounds, as of voices deep down under the flood, glass splintering, rocks rumbling.

The gorge seemed inhabited by furies.

And back of this came the pressure of twenty miles of water, a hundred feet deep, which would come through.
