As the gates, with accelerated motion when the current caught them, clanged together, we beheld a spectacle that almost stopped the beating of our hearts.
The great Syrtis seemed to gather itself for a moment, and then it leaped upon the obstruction and buried its waters into one vast foaming geyser that seemed to shoot a thousand feet skyward.
But the metal gates withstood the shock, though buried from our sight in the seething white mass, and the baffled waters instantly swirled around in ten thousand gigantic eddies, rising to the level of our window and beginning to inundate the power house before we fairly comprehended our peril.
"We have done the work," said Mr. Edison, smiling grimly. "Now we had better get out of this before the flood bursts upon us."
The warning came none too soon. It was necessary to act upon it at once if we would save our lives. Even before we could reach the entrance to the long passage through which we had come into the great engine room, the water had risen half-way to our knees. Colonel Smith, catching Aina under his arm, led the way. The roar of the maddened torrent behind deafened us.
As we ran through the passage the water followed us, with a wicked swishing sound, and within five seconds it was above our knees; in ten seconds up to our waists.
The great danger now was that we should be swept from our feet, and once down in that torrent there would have been little chance of our ever getting our heads above its level. Supporting ourselves as best we could with the aid of the walls, we partly ran, and were partly swept along, until when we reached the outer end of the passage and emerged into the open air, the flood was swirling about our shoulders.
Here there was an opportunity to clutch some of the ornamental work surrounding the doorway, and thus we managed to stay our mad progress, and gradually to work out of the current until we found that the water, having now an abundance of room to spread, had fallen again as low as our knees.
But suddenly we heard the thunder of the banks tumbling behind us, and to the right and left, and the savage growl of the released water as it sprang through the breaches.
To my dying day, I think, I shall not forget the sight of a great fluid column that burst through the dike at the edge of the grove of trees, and, by the tremendous impetus of its rush, seemed turned into a solid thing.
