of two or three hundred feet, with an opening into a large chamber beyond, on the further side of which we could see part of a gigantic and complicated mass of machinery.
Making as little noise as possible, we pushed ahead along the passage, but when we had arrived within a distance of a dozen paces from the inner end, we stopped, and Colonel Smith, getting down upon his knees, crept forward until he had reached the inner end of the passage. There he peered cautiously around the edge into the chamber, and, turning his head a moment later, beckoned us to come forward. We crept to his side, and, looking out into the vast apartment, could perceive no enemies.
What had become of the sentinels supposed to stand at the inner end of the passage we could not imagine. At any rate, they were not at their posts.
In the Great Power House.
The chamber was an immense square room at least a hundred feet in height and 400 feet on a side, and almost filling the wall opposite to us was an intricate display of machinery, wheels, levers, rods and polished plates. This we had no doubt was one end of the great engine which opened and shut the great gates that could dam an ocean.
"There is no one in sight," said Colonel Smith.
"Then we must act quickly," said Mr. Edison.
"Where," he said, turning to Aina, "is the handle by turning which you saw the Martian close the gates?"
Aina looked about in bewilderment. The mechanism before us was so complicated that even an expert mechanician would have been excusable for finding himself unable to understand it. There were scores of knobs and handles, all glistening in the electric light, any one of which, so far as the uninstructed could tell, might have been the master key that controlled the whole complex apparatus.
The Magic Lever!
"Quick," said Mr. Edison, "where is it?"
The girl in her confusion ran this way and that, gazing hopelessly upon the machinery, but evidently utterly unable to help us.
To remain here inactive was not merely to invite destruction for ourselves, but was sure to bring certain failure upon the purpose of the expedition. All of us began instantly to look about in search of the proper handle, seizing every crank and wheel in sight and striving to turn it.
"Stop that!" shouted Mr. Edison, "you may set the whole thing wrong. Don't touch anything until we have found the right lever."
But to find that seemed to most of us now utterly beyond the power of man.
It was at this critical moment that the wonderful depth and reach of Mr. Edison's mechanical genius displayed itself. He stepped back, ran his eye quickly over the whole immense mass of wheels, handles, bolts, bars and levers, paused for an instant, as if making up his mind, then said decidedly, "There it is," and, stepping quickly forward, selected a small wheel amid a dozen others, all furnished at the circumference with handles like those of a pilot's wheel, and, giving it a quick wrench, turned it half way around.
Surprised by the Enemy.
At this instant, a startling shout fell upon our ears. There was a thunderous clatter behind us, and, turning, we saw three gigantic Martians rushing forward.
Chapter XV.
"Sweep them! Sweep them!" cried Colonel Smith, as he brought his disintegrator to bear. Mr. Phillips and I instantly followed his example, and thus we swept the Martians into eternity, while Mr. Edison coolly continued his manipulations of the wheel.
The effect of what he was doing became apparent in less than half a minute. A shiver ran through the mass of machinery and shook the entire building.
"Look! look!" cried Sidney Phillips, who had stepped a little apart from the others.
The Grand Canal.
We all ran to his side and found ourselves in front of a great window which opened through the side of the engine, giving a view of what lay in front of it. There, gleaming in the electric lights, we saw the Syrtis Major, its waters washing high against the walls of the vast power house. Running directly out from the shore, there was an immense metallic gate at least 400 yards in length and rising 300 feet above the present level of the water.
This great gate was slowly swinging upon an invisible hinge in such a manner that in a few minutes it would evidently stand across the current of the Syrtis Major at right angles.
Beyond was a second gate, which was moving in the same manner. Further on was a third gate, and then another, and another, as far as the eye could reach, evidently extending in an unbroken series completely across the great strait.
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.
A Great Rush of Waters.
The great Syrtis seemed to gather itself for a moment, and then it leaped upon the obstruction and hurled 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 round 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.
Escaping the Water.
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 dyke at the edge of the grove of trees, and, by the tremendous impetus of its rush, seemed turned into a solid thing.
Like an enormous ram, it plowed the soil to a depth of twenty feet, uprooting acres of the immense trees like stubble turned over by the plowshare.
The uproar was so awful that for an instant the coolest of us lost our self-control. Yet we knew that we had not the fraction of a second to waste. The breaking of the banks had caused the water again rapidly to rise about us. In a little while it was once more as high as our waists.
In the excitement and confusion, deafened by the noise
