"Sure. Publicity stunt about a year ago. Dumb bunny of a publicity man. Photographed on the old lady's spikes. Never will again."

The spiral ended, a side passage branched off. The dancer stopped.

"Sh," she said, "someone's coming. Duck in here." She seized Sherman's hand and led him into the side passage, down which they ran for a few feet, then paused to look back. Down the passage they had just vacated came a group of the ape-men, four or five of them, each carrying on his left arm a long, cylindrical shield like those one sees in pictures of Roman soldiers, and in his right hand some instrument that looked like a fire extinguisher with a long, flexible nozzle.

Each of the group wore one of the helmets and behind them, wearing a similar headgear to which all the tubes were connected from the ape-men's helmets came one of the Lassans. The group hurried past without a sideward glance, the metal feet of the ape-men ringing oddly loud on the granite of the echoing passage. After a minute Sherman and the dancer crept cautiously forward; the procession had gone straight on down. Very likely a wrecking crew.

Sherman and Marta sprinted up the passage in the direction from which the ape-men and their guide had come. The passage no longer rose with the same steepness, and as the ascent grew more gentle, the tunnel widened, with frequent side-passages to the right and branches leading down to the track at the left. Finally, after a sharp turn, it opened out into a big room, untenanted like all they had seen so far, filled with a complex maze of machinery, but machinery of a different character from that they had labored at. At the farther end of the room a door stood open. They dashed across it, plunged through—and found themselves in one of the enormous blue-domed halls, whose ceiling seemed to stretch miles above them.


It must have been all of three hundred feet across, and there was no visible support for the ceiling. All about the place stood various objects and pieces of machinery, and figures moved dimly among the titanic apparatus at the far end. But what most attracted their attention was the huge object that stood right before them.

It looked like a metal fish on an enormous scale. Fully fifty feet long and twenty feet high, its immense proportions dwarfed everything about it, and its sides, of brilliantly polished metal, shone like a mirror. The tail came to a stubby point, from which projected a circle of four tubes; down the side was a rib which ended in a similar tube about half way, and at the nose-end of the mechanical fish was a ten-foot snout, not unlike an elephant's trunk in shape and apparently made of the same rubbery material which held the cables of the helmets.

Marta pulled Sherman down behind the thing, and they peered around the edge seeking for a means of egress from the room. The nearest was twenty or thirty feet away. Watching their opportunity, they chose a moment when they seemed least likely to attract attention and made a dive for it.

They found themselves in another passage, terminating in two doors.
