They worked hard at shifting the cargo into the cache, but the Nameless Sun was beginning to slide down behind the mountains before they were finished. And by the time Channok had rammed the tunnel full of rocks with the tractor and cemented them into a glassy plug with the drill-blast, and scattered a camouflaging mess of boulders over everything, only a foggy red glow over the mountain crests, half obscured by the lingering upper drifts of the explosion of the Ra-Twelve, remained of the day.
There was no moon, but the sky had come full of stars big and little over the opposite section of the plain; and so there was light enough to make out the dark hump of the Mound in the distance. Every time Channok looked in that direction, the low, sinister pile seemed to have edged a little closer; and he looked as often as his work gave him a chance to do it. Santis might have been right in stating that the Mound wasn't dangerous if you didn't get too close to it—but the instant he suspected there might be something going on over there, Channok was going to hop off the tractor, grab up Peer and get off Old Nameless at the best speed he and the Asteroid could produce.
However, the Mound remained quiet. With everything done, he gave Peer a last ride back to the Asteroid on the tractor, ran it up the ramp into the storage section and closed the rear lock. Then they discovered they'd left their lunch containers lying among the rocks.
If he'd been alone, Channok would have left them there. But Peer looked so matter-of-fact about it that he detached the tractor's headlight and started back with her on foot. It was only a couple of hundred yards, and they found the containers without any difficulty. The Mound seemed to have moved a little closer again, but not too much. He gave it only a casual glance this time.
"Where are your friends, the ghouls?" he inquired, shining the light around the rocks as they started back. The grisly creatures had put in a few cautious appearances during the afternoon, but their nerves seemed to have suffered even more than his own from all that had happened.
"The ghouls always hit their burrows at sundown," Peer explained. "They're not like the story ones."
"What do they find to eat around here?" Channok inquired.
"Some sorts of rocks. They've got no real teeth but their mouth is like a grinder inside. Most of the rest of their insides, too, Santis said. I had a tame one I used to pitch stones at and he'd snap 'em up. But all that weren't blue he'd spit out. The blue ones went right down—you could hear them crunching for about a foot."
"What a diet!" Channok commented. Then he stopped short. "Say, Peer! If they bite like that, they could chew right into our cache!"
