The four Earth couples clambered down from their trailer. They were fully in character, behaving exactly as Gundersen’s harsh image of them would have them behave: they seemed bored and glazed, surfeited with the alien wonders they had already seen. Stein, the helix-parlor proprietor, dutifully checked the aperture of his camera, mounted it in his cap, and routinely took a 360-degree hologram of the scene; but when the printout emerged from the camera’s output slot a moment later he did not even bother to glance at it. The act of picture-taking, not the picture itself, was significant. Watson, the doctor, muttered a joyless joke of some sort to Christopher, the financier, who responded with a mechanical chuckle. The women, bedraggled and jungle-stained, paid no attention to the lake. Two simply leaned against the beetle and waited to be told what it was they were being shown, while the other two, as they became aware of Gundersen’s presence, pulled facial masks from their backpacks and hurriedly slipped the thin plastic films over their heads so that they could present at least the illusion of properly groomed features before the handsome stranger.
“I won’t stay here long,” Gundersen heard himself promising Srin’gahar, as he dismounted.
Van Beneker came up to him. “What a trip!” the little man blurted. “What a stinking trip! Well, I ought to be used to it by now. How’s everything been going for you, Mr. G?”
“No complaints.” Gundersen nodded at the trailer. “Where’d you get that noisy contraption?”
“We built it a couple of years ago when one of the old cargo haulers broke down. Now we use it to take tourists around when we can’t get any nildoror bearers.”
“It looks like something out of the eighteenth century.”
“Well, you know, sir, out here we don’t have much left in the way of modern equipment. We’re short of servos and hydraulic walkers and all that. But you can always find wheels and some planks around. We make do.”
“What happened to the nildoror we were riding coming from the spaceport to the hotel? I thought they were willing to work for you.”
“Sometimes yes, sometimes no,” Van Beneker said. “They’re unpredictable. We can’t force them to work, and we can’t hire them to work. We can only ask them politely, and if they say they’re not available, that’s it. Couple of days back, they decided they weren’t going to be available for a while, so we had to get out the trailer.” He lowered his voice. “If you ask me, it’s on account of these eight baboons here. They think the nildoror don’t understand any English, and they keep telling each other how terrible it is that we had to hand a planet as valuable as this over to a bunch of elephants.”
“On the voyage out here,” said Gundersen, “some of them were voicing quite strong liberal views. At least two of them were big pro-relinquishment people.”
“Sure. Back on Earth they bought relinquishment as a political theory. ‘Give the colonized worlds back to their long-oppressed natives,’ and all that. Now they’re out here and suddenly they’ve decided that the nildoror aren’t ‘natives,’ just animals, just funny-looking elephants, and maybe we should have kept the place after all.” Van Beneker spat. “And the nildoror take it all in. They pretend they don’t understand the language, but they do, they do. You think they feel like hauling people like that on their backs?”
“I see,” said Gundersen. He glanced at the tourists. They were eyeing Srin’gahar, who had wandered off toward the bush and was energetically ripping soft boughs loose for his midday meal. Watson nudged Miraflores, who quirked his lips and shook his head as if in disapproval. Gundersen could not hear what they were saying, but he imagined that they were expressing scorn for Srin’gahar’s enthusiastic foraging. Evidently civilized beings were not supposed to pull their meals off trees with their trunks.
Van Beneker said, “You’ll stay and have lunch with us, won’t you, Mr. G?”
“That’s very kind of you,” Gundersen said.
He squatted in the shade while Van Beneker rounded up his charges and led them down to the rim of the steaming lake. When they were all there Gundersen rose and quietly affiliated himself with the group. He listened to the guide’s spiel, but managed to train only half his attention on what was being said. “High-temperature life-zone … better than 70°C … more in some places, even above boiling, yet things live in it … special genetic adaptation … thermophilic, we call it, that is, heat-loving … the DNA doesn’t get cooked, no, but the rate of spontaneous mutation is pretty damned high, and the species change so fast you wouldn’t believe it … enzymes resist the heat … put the lake organisms in cool water and they’ll freeze in about a minute … life processes extraordinarily fast … unfolded and denatured proteins can also function when circumstances are such that … you get quite a range up to middle-phylum level … a pocket environment, no interaction with the rest of the planet … thermal gradients … quantitative studies … the famous kinetic biologist, Dr. Brock … continuous thermal destruction of sensitive molecules … unending resynthesis…”
Srin’gahar was still stuffing himself with branches. It seemed to Gundersen that he was eating far more than he normally did at this time of day. The sounds of rending and chewing clashed with the jerky drone of Van Beneker’s memorized scientific patter.
Now, unhooking a biosensitive net from his belt, Van Beneker began to dredge up samples of the lake’s fauna for the edification of his group. He gripped the net’s handle and made vernier adjustments governing the mass and length of the desired prey; the net, mounted at the end of an almost infinitely expandable length of fine flexible metal coil, swept back and forth beneath the surface of the lake, hunting for organisms of the programmed dimensions. When its sensors told it that it was in the presence of living matter, its mouth snapped open and quickly shut again. Van Beneker retracted it, bringing to shore some unhappy prisoner trapped within a sample of its own scalding environment.
Out came one lake creature after another, red-skinned, boiled-looking, but live and angry and flapping. An armored fish emerged, concealed in shining plates, embellished with fantastic excrescences and ornaments. A lobster-like thing came forth, lashing a long spiked tail, waving ferocious eye-stalks. Up from the lake came something that was a single immense claw with a tiny vestigial body. No two of Van Beneker’s grotesque catches were alike. The heat of the lake, he repeated, induces frequent mutations. He rattled off the whole genetic explanation a second time, while dumping one little monster back into the hot bath and probing for the next.
The genetic aspects of the thermophilic creatures seemed to catch the interest of only one of the tourists — Stein, who, as a helix-parlor owner specializing in the cosmetic editing of human genes, would know more than a little about mutation himself. He asked a few intelligent-sounding questions, which Van Beneker naturally was unable to answer; the others simply stared, patiently waiting for their guide to finish showing them funny animals and take them somewhere else. Gundersen, who had never had a chance before to examine the contents of one of these high-temperature pockets, was grateful for the exhibition, although the sight of writhing captive lake-dwellers quickly palled on him. He became eager to move on.
He glanced around and discovered that Srin’gahar was nowhere in sight.
“What we’ve got this time,” Van Beneker was saying, “is the most dangerous animal of the lake, what we call a razor shark. Only I’ve never seen one like this before. You see those little horns? Absolutely new. And that lantern sort of thing on top of the head, blinking on and off?” Squirming in the net was a slender crimson creature about a meter in length. Its entire underbelly, from snout to gut, was hinged, forming what amounted to one gigantic mouth rimmed by hundreds of needle-like teeth. As the mouth opened and closed, it seemed as if the whole animal were splitting apart and healing itself. “This best feeds on anything up to three times its own size,” Van Beneker said. “As you can see, it’s fierce and savage, and—”
