Pauncho came down, grunting, and then Barney.
The moment Barney landed, the world seemed to tilt. Doc made a leap forward for the shaft with his left hand, which still held the disc, extended. And when the disc slapped onto the inner edge of the lip of the shaft, he squeezed down on the handle. The disc held, and he hung there, while the ladder, his rifle, and his two friends went down the slope of the tunnel, which had suddenly dropped and was rapidly becoming vertical.
Sick, he looked down past his feet while Pauncho and Barney, their fingers grabbing for a hold on the smooth stone - or what seemed like stones but could not be - hurtled downward. And then they were gone around the bend, shot out of the gigantic chuteychute. The rifle went with them, and the ladder, bending at a number of places like a wooden snake, shot out by their side.
Panicked though they must have been, neither had screamed or yelled. Pauncho had groaned, and Barney had hissed between clamped teeth, but that was all.
Doc hung there, rotating slowly by the turning of his wrist. He could swing himself up and get his feet against the wall of the shaft and so climb back up to its top. Or he could swing out and back until he had enough momentum and then release the disc and land on the edge of the newly formed vertical shaft and go on down this tunnel. Or he could then climb down the chuteychute, using the discs and see what was down there. It seemed certain that Iwaldi would be waiting for him there, but he could not abandon his colleagues, not unless he knew for certain that he could help them by action elsewhere.
Within a minute, he was going down the shaft of the trap. When he came to the bend he proceeded more slowly. He lifted the goggles for a moment and, seeing that there was light ahead, left them up. He could see only a whitewashed wall ahead, but when he got to the end of the tube and looked down, he saw Pauncho and Barney.
Below them was another shaft about twenty feet wide and so deep he could not see the bottom. The shaft was in the centre of a large room which seemed to be the storehouse for hundreds of wooden brightly painted statues. These ranged from beautiful nudes and fully clothed humans and dwarfish peoples to dragons to elk to wolves to badgers to monsters of various sorts. The light came from a dozen glass bulbs on top of stone lamps.
Pauncho and Barney were at the bottom of a net. This was composed of many thin and apparently sticky cords. Their weight had pulled the net, which originally had been stretched across the top of the shaft, to a bag-like shape with them at the bottom and about twenty feet down the shaft. They were struggling and cursing in low tones, but their efforts only entangled them more thoroughly in the cords. Seeing Doc Caliban, they stopped thrashing around.
'Get me out of here, Doc,' Barney said. "This guy's so hairy, he's making me itch.'
'Yeah, get me out of here,' Pauncho said. 'He's so bony he's cutting me.'
Doc did not answer. He began to swing back and forth until he had enough momentum. He released the pressure on the disc handle as he started an outward swing, and he landed on the edge of the shaft. Neither of the two made a sound, though it might have been expected that Doc would teeter back and fall into the net with them. His toes only struck the lip of the shaft. But he snapped himself forward and then was solidly on the floor. He turned and began to pull on the net, hauling up the four hundred and seventy pounds of the two men and the hundred pounds of the net as if they were a minnow on a string.
The sticky cords clung to his hands, but he just walked backward, pulling the two over the edge with a bump and a scrape that brought groans from them. After they were on the floor, he managed to pull his hands loose and then he started the tedious and slow task of freeing them.
When they were out of the net, Pauncho and Barney were as dirty looking as coal miners at the end of a shift. The dark brown substance had smeared their clothes, faces, and hands.
'One thing I'll say,' Barney muttered. 'You look just as good dirty as you do clean. Maybe better because it's more natural.'
Pauncho's thick teeth flashed in a grin. 'As an authority on dirt, your opinion is to be valued. It takes one to know one, as they say.'
Takes one what to know what one?' Barney said.
'If you two will quit your clowning around now,' Doc Caliban said, 'we'll proceed. Though where I don't know.'
From a pocket in his vest he took an object the size and shape of a large pocketwatch. Its face bore a number of dials and graduated markings and also a thin tube with a red column, like a thermometer. The others did not comment. They knew that this was a device with several functions. One of them was to detect objects of a certain shape and density. The device could be set to register when such and such an object was near its field of radiation. Doc now adjusted it by turning a small wheel on its back, and then he advanced down the room holding it out before him.
If there was anything immediately behind the walls or under the floors or above the ceiling, this detector would send a pulse of yellow light up and down the column on its face. The drawback of the detector was that it could not be used in the near vicinity of guns and knives or other considerable masses of metal. It registered the metal even if its radiating field was directed away from the metal. There was a certain amount of back radiation, an echo as it were, and this detected the metal. So Doc Caliban had to give his pistol and knife to Pauncho to carry while he preceded them by thirty feet.
He stopped at a wooden ladder sticking out of a shaft and the two halted with the same distance maintained between them and their leader. He swept the detector around and then went down the ladder. They followed a minute later. The next level down was a long corridor hewn out of solid granite. It ran for as far as they could see in both directions, and it was well lit with naked electric light bulbs on iron brackets about five feet from the floor and spaced about forty feet apart.
Doc sprayed some more of the atomised differential-level substance around. It revealed many footprints, but the freshest seemed to go off to the right, so he elected to go that way. They passed tools lying on the floor or propped against the walls: picks with broken handles or worn points; great sledges, bars with chiselled edges, brooms. Some of them looked as if they had been lying here a long time. Then they came to a broad staircase cut out of the rock. It led down for about sixty feet at a steep angle. They went down it, still guided by the electric light bulbs, and came to a room at least a hundred feet square and forty high.
Doc stopped, and Pauncho and Barney, forgetting that they were not to get close, almost bumped into him. The red column in the centre of the face changed to a bright yellow light which pulsed.
Doc told them to move back, and the light went back to its quiescent state.
Barney whistled softly and said, 'Looks like they had a fight sometime ago, doesn't it? A long time ago!'
The footprints were plain here. The dust was so thick that it rose with every step. Pauncho almost strangled trying to keep from sneezing while Barney choked trying to keep from laughing at Pauncho's desperate grimaces.
There were about ten complete skeletons and parts of others scattered around the room. Rusty swords, knives, and double-headed axes lay under the dust, many still clutched by bony hands. Some of the skulls had been cracked or caved in; an axe was still wedged in the top of a skull.
Doc said, 'Most of them were dwarfs. And an early type of Homo sapiens. Look at the thickness of those bones, the huge supraorbital ridges.'
