"I do not know."
The Robot was stooping to the floor. "It is a plain trail," it said. "Come."[2]
[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 passages 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."
he 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?"
