Migul had struck the main trail, now. We pa.s.sed the lighted room again, went on to a cave-like open s.p.a.ce with a litter of abandoned machinery and unswervingly to a blank s.p.a.ce of the opposite wall.
Again Migul faltered.
"What"s the matter, Migul?"
"His vibrations are faint. They are blurred with the Princess Tina"s."
"Then she is with him?"
It was a tremendous relief. Larry doubtless was with them also.
"Is the man from 1935 with Tugh and the Princess?" I asked.
"I think so. There are unfamiliar vibrations--perhaps those of the man from the past."
The Robot was running the filaments of its fingers lightly over the wall.
"I have it. The Princess pressed this switch."
The door opened; the narrow descending tunnel was wholly black.
"Where does this go, Migul?"
"I do not know."
The Robot was stooping to the floor. "It is a plain trail," it said.
"Come."[2]
[Footnote 2: Had Migul at that juncture traced Tina"s movements--her hand where it went along the tunnel-wall--we would have found the light switch. But it chanced that the Robot"s fingers went at once to the ground and caught the foot-trail of Tugh.]
The remainder of that journey through the labyrinth of pa.s.sages was made in blank darkness, with only the faint lurid red beams from Migul"s eye-sockets to light our way. But we went swiftly, and without incident. At last we went under the dam, up the spiral stairs and upon the catwalk above the abyss, where the great spillway of falling water arched out over us.
"The Power House," said Migul, "is where they went."
The Robot was obviously frightened, now. We were wet with spray. "I should not be here," it said. "If the water gets into me--even though I am well insulated--I will be destroyed!"
I recall as I write this how in Patton Place of 1935, one of the first attacking Robots had exploded under a jet of water from the street hydrant.
"I will stay behind you," Migul added. "They have a deranging ray in the Power House, and they might use it on me. Will you protect me?"
"Yes, of course," I said.
I was ready to promise anything, if only I could get to Larry and Tina, then back with them to Mary into the Time-cage; and if we were safely out of this era, most a.s.suredly I wanted none of it again.
Migul, as I advanced along the catwalk, followed behind me.
"You will kill Tugh?" it reiterated like an anxious child.
"Yes."
I saw that the catwalk terminated ahead under the Power House, where steps led upward. Then I heard a cry:
"Help! Help! Here, inside the dam! Help!"
I stood transfixed, with horror tingling my flesh. The voice came faintly from near at hand; it was m.u.f.fled, and in the roar of the falling water and lashing spray I barely heard it.
Then it came again. "Help us! Help us, quickly!"
It was an agonized, panting, human voice. And in a chance, partial lull I heard it now plainly.
It was Larry"s voice!
CHAPTER XXI
_The Fight in the Power House_
I found the narrow aperture and stood peering down into darkness.
Migul crowded behind me. The red beams of its eyes went down into the pit, and by their faint illumination I saw the heads of Larry and a girl, swimming twenty feet below. The girl"s dark hair floated out like black seaweed in the water.
"The Princess and the strange man!" exclaimed Migul.
I called, "Larry! Larry!"
His labored voice came up. "George? Thank G.o.d! Get us--out of here.
Almost--gone, George!"
I found my wits: "Then keep quiet! Don"t talk. Save your strength.
I"ll get you out!"
But how? I could see that they were almost spent, for they were swimming with labored, inefficient strokes--Larry using most of his strength to hold up the exhausted girl. We had not a moment to spare.
I wildly contemplated tearing my garments to make a rope.
But Migul pushed me away. "I will bring them. Stand back."
The Robot had opened its metal side and drawn forth a flexible wire with a foot-long hook fastened to it. The wire came smoothly out as though unrolling from a drum.
It leaned into the aperture and called down to Larry. "Fasten this around the Princess. Be careful not to harm her. Put it under her arms."
I saw that there was an eyelet on the wire into which the hook could be inserted to make a loop.
"Under her arms," Migul called. "She will have to hold to the hook with her hands or the wire will cut into her. Has she the strength?"
Larry floundered as he adjusted the wire. Tina gasped. "I--have the strength."
