The Robot braced itself, spreading its knees against the aperture with its body leaning forward.
"Ready?" it called.
"Yes," came Larry"s voice.
Migul"s finger pressed a b.u.t.ton at the base of its neck, and with the smooth power of machinery the wire cable rolled into its side. Tina came up; Migul gripped her and pulled her through the aperture; laid her gently on the catwalk. I unfastened the hook, and soon Migul had Larry up with us.
The Robot stood aside, with its work done, silently regarding us. I need not detail this reunion of Larry and me there on the spray-swept catwalk, clinging to the side of the great dam with the foaming Hudson beneath us. Larry and Tina were not injured, and presently their strength partially returned. We hastily sketched what had happened to each of us.
It was Tugh who was the guiding evil genius of all these disasters!
Tugh, the exile of Time, the ruthless murderer in many eras! He was here, very probably, in the Power House, a few hundred feet away.
And Tina, regarding that Power House with her returning clarity of senses saw that its sending signal lights were off, which meant that the air-power of the New York District was not being supplied. Help from other cities could not arrive.
Tina stood up waveringly. "We cannot stay here like this!" she said.
"Tugh has killed the guards, and is there in control. The electrical defenses are shut off; they must be! The Robots will soon be coming along the top of the dam, for their battery renewers are stored in the Power House. If they get them, this ma.s.sacre will go on for days!--and spread all over! We"ve got to stop them! We must get in the Power House and capture Tugh!"
"But we have no weapons!" Larry cried. "And he must have that white-ray, if he has killed the guards!"
"I have a weapon!" I said. I had suddenly recalled the cylinder in my pocket. "I have a white-ray!"
A desperate madness was on us all. The lives of thousands of people who might still be alive on Manhattan were at stake; and other millions would be menaced if these Robots renewed their energy and spread the revolt into other cities.
Over the roar, and the wind lashing us, I shouted:
"I promised Migul I would kill Tugh. I will!"
I turned toward Migul. But the Robot had vanished! Afraid, no doubt, that we would want it to go with us after Tugh, the terrified mechanism was hiding. We wasted no time searching for it.
We had all been half hysterical for these few moments, but we steadied quickly enough as we approached the Power House"s lower entrance. The building was a rectangular structure some two hundred feet long. It was fastened upon great brackets to the perpendicular side of the dam and jutted out some fifty feet. It was two levels in height--a total of about forty feet to its flat roof, in the center of which was set a small oval tower. The whole structure was above us now; the catwalk went close underneath it, pa.s.sing through an arch of the huge supporting brackets and terminating in a small lower platform, with an open spiral staircase leading upward some ten feet into the lower story.
The place seemed dark and deserted as we crept up to it. Gazing above me, I could see the top of the dam, now looming above the Power House.
There was a break in the spillway at this point. The arching cascade of water under which the catwalk hung ended here. We came out where there was a vista of the lower Hudson beneath us, showing dimly down past the docklights and skeleton landing stages to the bay.
The sky was visible now and the open wind struck us full. It was a crazy pendulum wind. A storm was breaking overhead. There were flares of lightning and thunder cracks--from disturbed nature, outraged by the temperature changes of the Robot"s red and violet rays.
The Power House, so far as we could see, was dark and deserted. Its normal lights were extinguished. Was Tugh in there? It was my weapon against his. The white-ray was new to Tina; we had no way of estimating this cylinder"s effective range.[3]
[Footnote 3: The cylinder of the white-ray which I carried was not the one with which Tugh murdered Harl. Mine was portable, and considerably smaller.]
I kept Tina and Larry well behind me. It was a desperate approach, and I was well aware of it. The catwalk now was illumined at intervals by the lightning; Tugh from many points of vantage in the Power House could have seen us and exterminated us with a soundless flash swift as a lightning bolt itself. But we had to chance it.
We reached the small lower platform. The catwalk terminated. The Power House was a roof over us. I stood at the foot of the spiral staircase, which went up through a rectangular opening in the floor. There was a vista of a dark room-segment.
"Keep behind me," I murmured, and I started up. Was Tugh lurking here, waiting for me to raise myself above this opening? If he had been, he could have held his position against a score of a.s.sailants.
But he was not. I soon stood breathlessly in a dark metal room. Tina and Larry came up.
"He"s not here," I whispered. It was more silent in here: the cascading water was further away from us now. There came a flash of lightning, followed in a few seconds by its accompanying thunder crash.
I started. "What"s that?"
On the floor near us lay a gruesome, crumpled thing. I bent over it, waiting for another flash. When one came I saw it was a heap of clothes, covering a white skeleton. By the garments Tina knew it was one of the guards.
We crept into a small interior corridor where a small light was burning. The remains of two other guards lay here, close by the doorway as though they had come running at Tugh"s alarm, only to be struck down.
It was horribly gruesome, here in the dimness with these bleached bones which had been living men so recently. And it was nerve-breaking to know that Tugh was doubtless here somewhere.
"Listen!" whispered Tina.
There was a crackling sound overhead, and then the blurred murmur of a voice. An audible broadcasting transmitter was in operation.
"It"s in the tower," said Tina swiftly. "Tugh must be there."
This was an infinite relief. We went to the top story, pa.s.sing, unheeding, another crumpled heap. Again we stood listening. The transmitter was hissing and spluttering, and then shouting its magnified human voice out into the night. It was Tugh up there. He was calling audibly to his Robots, with words which would be relayed upon all the local magnifiers in the city. Between the thunder cracks we heard him plainly now.
"_This is your Master Tugh in the Power House. Robots, we are triumphant! The city is isolated! No help can get in! Kill all humans!
Spare none! This night sees the end of human rule!_"
And again: "_When you want renewal, come along the top roadway of the dam. The electric defenses are off. You can come, and I have your renewers here. I have new batteries, new strength for you Robots!_"[4]
[Footnote 4: Tugh had been in the Power House before. He knew the operations of its various controls. But he had come always by the surface route; he had heard of the existence of the secret tunnel, but had never before this night been able to find out where it was.]
"You stay here," I told Tina and Larry; "I"ll go up there. I"ll get him now once and for all."
I reached the Power House roof. The storm tore at me. It was beginning to rain. I was near the outer edge of the roof, and ten feet away stood the oval tower. I saw windows twenty feet up, with dim lights in them. Mingled with the storm was the hiss of the transmitter in the top of the tower, and the roar of Tugh"s magnified voice. He had evidently been there only a brief time. From where I crouched on the roof, I could see overhead, along the top edge of the dam looming above me. The red Robot rays were everywhere in the city, but none as yet showed along the dam"s upper roadway.
I got into the tower and mounted its small stairs. Creeping cautiously to the entrance of the control room, I saw a fairly large, dimly lighted oval apartment. Great banks of levers stood around it; tables of control apparatus; rows of dials, illumined by tiny lights like staring eyes. There was another gruesome heap of garments here on the floor; a grinning white skull leered at me.
This was the main control room of the Power House. Across it, near an open window, Tugh sat with his back to me, bent over a table with the grid of a microphone before him. I raised my cylinder; then lowered it, for I had only a partial view of him: a huge transformer stood like a barrier between us.
Noiselessly I stepped over the threshold, and to one side within the room. The place was a buzz and hiss of sound topped by Tugh"s broadcast voice and the roar of the storm outside--yet he was instantly aware of me! His voice in the microphone abruptly stopped; he rose and with an incredibly swift motion whirled and flung at me a heavy metal weight which had been lying on the table by his hand. The missile struck my outstretched weapon just as I was aiming it to fire, and the cylinder, undischarged, was knocked from my hand and went spinning across the floor several feet away from me.
Tugh, like an uncoiling spring, still with one continuous motion, made a leap sidewise to where his own weapon was lying on a bench, and I saw he would reach it before I could retrieve mine.
I flung my heavy battery box but missed him. And as I rushed at him he caught up his cylinder and fired it full at me! But no flash came: only a click. He had exhausted its charge when he killed the Power House guards. With a curse he flung it at my face, and my arm took its blow just as I struck him. We fell gripping each other, and rolled on the floor.
