Of course-He was not wearing a space suit now.
He was standing on a habitable world, as comfortable to the feel as Terminus would be-far more comfortable than Comporellon had been. He experienced the wind against his cheek, the warmth of the sun on his back, the rustle of vegetation in his ears. Everything was familiar, except that there were no human beings on it-at least, not any longer.
Was that it? Was it that that made the world seem so eerie? Was it that it was not merely an uninhabited world, but a deserted one?
He had never been on a deserted world before; never heard of a deserted world before; never thought a world could be deserted. All the worlds he had known of till now, once they had been populated by human beings, remained so populated forever.
He looked up toward the sky. Nothing else had deserted it. An occasional bird flew across his line of vision, seeming more natural, somehow, than the slate-blue sky between the orange-tinted fair-weather clouds. (Trevize was certain that, given a few days on the planet, he would become accustomed to the off-color so that sky and clouds would grow to seem normal to him.)
He heard birdsongs from the trees, and the softer noise of insects. Bliss had mentioned butterflies earlier and here they were-in surprising numbers and in several colorful varieties.
There were also occasional rustlings in the clumps of grass that surrounded the trees, but he could not quite make out what was causing them.
Nor did the obvious presence of life in his vicinity rouse fear in him. As Bliss had said, terraformed worlds had, from the very first, lacked dangerous animals. The fairy tales of childhood, and the heroic fantasies of his teenage years were invariably set on a legendary world that must have been derived from the vague myths of Earth. The hyperdrama holoscreen had been filled with monsters-lions, unicorns, dragons, whales, brontosaurs, bears. There were dozens of them with names he could not remember; some of them surely mythical, and perhaps all of them. There were smaller animals that bit and stung, even plants that were fearful to the touch-but only in fiction. He had once heard that primitive honeybees were able to sting, but certainly no red bees were in any way harmful.
Slowly, he walked to the right, skirting the border of the hill. The grass was tall and rank, but sparse, growing in clumps. He made his way among the trees, also growing in clumps.
Then he yawned. Certainly, nothing exciting was happening, and he wondered if he might not retreat to the ship and take a nap. No, unthinkable. Clearly, he had to stand on guard.
Perhaps he ought to do sentry duty-marching, one, two, one two, swinging about with a snap and performing complicated maneuverings with a parade electro-rod. (It was a weapon no warrior had used in three centuries, but it was still absolutely essential at drill, for no reason anyone could ever advance.)
He grinned at the thought of it, then wondered if he ought to join Pelorat and Bliss in the ruins. Why? What good would he do?
Suppose he saw something that Pelorat had happened to overlook?-Well, time enough to make the attempt after Pelorat returned. If there was anything that might be found easily, by all means let Pelorat make the discovery.
Might the two be in trouble? Foolish! What possible kind of trouble?
And if there were trouble, they would call out.
He stopped to listen. He heard nothing.
And then the irresistible thought of sentry duty recurred to him and h1 found himself marching, feet moving up and down with a stamp, an imaginary electro-rod coming off one shoulder, whirling, and being held out straight before him, exactly vertical-whirling again, end over end, and back over the other shoulder. Then, with a smart about-face, he was looking toward the ship (rather far-off now) once more.
And when he did that, he froze in reality, and not in sentry make-believe.
He was not alone.
Until then, he had not seen any living creature other than plant growl insects, and an occasional bird. He had neither seen nor heard anything approach-but now an animal stood between him and the ship.
Sheer surprise at the unexpected event deprived him, for a moment, of the ability to interpret what he saw. It was not till after a perceptible interval that he knew what he was looking at.
It was only a dog.
Trevize was not a dog person. He had never owned a dog and he felt no surge of friendliness toward one when he encountered it. He felt no such surge this time, either. He thought, rather impatiently, that there was no world on which these creatures had not accompanied men. They existed in countless varieties and Trevize had long had the weary impression that each world had at least one variety characteristic of itself. Nevertheless, all varieties were constant in this: whether they were kept for entertainment, show, or some form of useful work-they were bred to love and trust human beings.
It was a love and trust Trevize had never appreciated. He had once lived with a woman who had had a dog. That dog, whom Trevize tolerated for the sake of the woman, conceived a deep-seated adoration for him, followed him about, leaned against him when relaxing (all fifty pounds of him), covered him with saliva and hair at unexpected moments, and squatted outside the door and moaned whenever he and the woman were trying to engage in sex.
From that experience, Trevize had emerged with the firm conviction that for some reason known only to the canine mind and its odor-analyzing ability, he was a fixed object of doggish devotion.
Therefore, once the initial surprise was over, he surveyed the dog without concern. It was a large dog, lean and rangy, and with long legs. It was staring at him with no obvious sign of adoration. Its mouth was open in what might have been taken as a welcoming grin, but the teeth displayed were somehow large and dangerous, and Trevize decided that he would be more comfortable without the dog in his line of view.
It occurred to him, then, that the dog had never seen a human being, and that countless canine generations preceding had never seen one. The dog might have been as astonished and uncertain at the sudden appearance of a human being as Trevize had been at that of the dog. Trevize, at least, had quickly recognized the dog for what it was, but the dog did not have that advantage. It was still puzzled, and perhaps alarmed.
Clearly, it would not be safe to leave an animal that large, and with such teeth, in an alarmed state. Trevize realized that it would be necessary to establish a friendship at once.
Very slowly, he approached the dog (no sudden motions, of course). He held out his hand, ready to allow it to be sniffed, and made soft, soothing sounds, most of which consisted of “Nice doggy”-something he found intensely embarrassing.
The dog, eyes fixed on Trevize, backed away a step or two, as though in distrust, and then its upper lip wrinkled into a snarl and from its mouth there issued a rasping growl. Although Trevize had never seen a dog behave so, there was no way of interpreting the action as representing anything but menace.
Trevize therefore stopped advancing and froze. His eyes caught motion to one side, and his head turned slowly. There were two other dogs advancing from that direction. They looked just as deadly as the first.
Deadly? That adjective occurred to him only now, and its dreadful appropriateness was unmistakable.
His heart was suddenly pounding. The way to the ship was blocked. He could not run aimlessly, for those long canine legs would reach him in yards. If he stood his ground and used his blaster, then while he killed one, the other two would be upon him. Off in the distance, he could see other dogs approaching. Was there some way in which they communicated? Did they hunt in packs?
Slowly, he shifted ground leftward, in a direction in which there were no dogs-as yet. Slowly. Slowly.
The dogs shifted ground with him. He felt certain that all that saved him from instant attack was the fact that the dogs had never seen or smelled anything like himself before. They had no established behavior pattern they could follow in his case.
If he ran, of course, that would represent something familiar to the dogs. They would know what to do if something the size of Trevize
showed fear and ran. They would run, too. Faster.
Trevize kept sidling toward a tree. He had the wildest desire to move upward where the dogs could not follow. They moved with him, snarling softly, coming closer. All three had their eyes fixed unwinkingly upon him. Two more were joining them and, farther off, Trevize could see still other dogs approaching. At some point, when he was close enough, he would have to make the dash. He could not wait too long, or run too soon. Either might be fatal.
Now!
He probably set a personal record for acceleration and even so it was a near thing. He felt the snap of jaws close on the heel of one foot, and for just moment he was held fast before the teeth slid off the tough ceramoid.
He was not skilled at climbing trees. He had not climbed one since he was ten and, as he recalled, that had been a clumsy effort. In this case, though, the trunk was not quite vertical, and the bark was gnarled and offered handholds. What was more, he was driven by necessity, and it is remarkable what one can do if the need is great enough.
Trevize found himself sitting in a crotch, perhaps ten meters above ground. For the moment he was totally unaware that he had scraped hand and that it was oozing blood. At the base of the tree, five dogs now on their haunches, staring upward, tongues lolling, all looking patiently expectant.
What now?
37.
TREVIZE WAS NOT in a position to think about the situation in logical detail. Rather, he experienced flashes of thought in odd and distorted sequence which, if he had eventually sorted them out, would have come to this-
Bliss had earlier maintained that in terraforming a planet, human Map would establish an unbalanced economy, which they would be able to keep from falling apart only by unending effort. For instance, no Settlers had brought with them any of the large predators. Small ones could not be helped. Insects, parasites-even small hawks, shrews, and so on.
Those dramatic animals of legend and vague literary accounts-tigers, grizzly bears, orcs, crocodiles? Who would carry them from world to world even if there were sense to it? And where would there be sense to it?
It meant that human beings were the only large predators, and it was up to them to cull those plants and animals that, left to themselves, would smother in their own overplenty.
And if human beings somehow vanished, then other predators must take their place. But what predators? The most sizable predators tolerated by human beings were dogs and cats, tamed and living on human bounty.
What if no human beings remained to feed them? They must then find their own food for their survival and, in all truth, for the survival of those they preyed on, whose numbers had to be kept in check lest overpopulation do a hundred times the damage that predations would do.
So dogs would multiply, in their variations, with the large ones attacking the large, untended herbivores; the smaller ones preying on birds and rodents. Cats would prey by night as dogs did by day; the former singly, the latter in packs.
And perhaps evolution would eventually produce more varieties, to fill additional environmental niches. Would some dogs eventually develop seagoing characteristics to enable them to live on fish; and would some cats develop gliding abilities to hunt the clumsier birds in the air as well as on the ground?
In flashes, all this came to Trevize while he struggled with more systematic thought to tell him what he might do.
The number of dogs kept growing. He counted twenty-three now surrounding the tree and there were others approaching. How large was the pack? What did it matter? It was large enough already.
He withdrew his blaster from its holster, but the solid feel of the butt in his hand did not give him the sense of security he would have liked. When had he last inserted an energy unit into it and how many charges could he fire? Surely not twenty-three.
What about Pelorat and Bliss? If they emerged, would the dogs turn on them? Were they safe even if they did not emerge? If the dogs sensed the presence of two human beings inside the ruins, what could stop them from attacking them there? Surely there would be no doors or barriers to hold them off.
Could Bliss stop them, and even drive them away? Could she concentrate her powers through hyperspace to the desired pitch of intensity? For how long could she maintain them?
Should he call for help then? Would they come running if he yelled, and would the dogs flee under Bliss’s glare? (Would it take a glare or was it simply a mental action undetectable to onlookers without the ability?) Or, if they appeared, would they then be torn apart under the eyes of Trevize, who would be forced to watch, helplessly, from the relative safety of his post in the tree?
No, he would have to use his blaster. If he could kill one dog and frighten them off for just a while, he could scramble down the tree, yell for Pelorat and Bliss, kill a second dog if they showed signs of returning, and all three could then hustle into the ship.
He adjusted the intensity of the microwave beam to the three-quartet mark. That should be ample to kill a dog with a loud report. The report would serve to frighten the dogs away, and he would be conserving energy.
He aimed carefully at a dog in the middle of the pack, one who seemed (in Trevize’s own imagination, at least) to exude a greater malignancy than the rest-perhaps only because he sat more quietly and, therefore, seemed more cold-bloodedly intent on his prey. The dog was staring directly at the weapon now, as though it scorned the worst Trevize could do.
It occurred to Trevize that he had never himself fired a blaster at a human being, or seen anyone else do it. There had been firing at water-filled dummies of leather and plastic during training; with the water almost instantaneously heated to the boiling point, and shredding the covering as it exploded.
But who, in the absence of war, would fire at a human being? And what human being would withstand a blaster and force its use? Only here, on world made pathological by the disappearance of human beings-
With that odd ability of the brain to note something utterly beside the point, Trevize was aware of the fact that a cloud had hidden the sun-and then he fired.
There was an odd shimmer of the atmosphere on a straight line from the muzzle of the blaster to the dog; a vague sparkle that might have gone unnoticed if the sun were still shining unhindered.
The dog must have felt the initial surge of heat, and made the smallest motion as though it were about to leap. And then it exploded, as a portion its blood and cellular contents vaporized.
The explosion made a disappointingly small noise, for the dog’s integument was simply not as tough as that of the dummies they had practiced on. Flesh, skin, blood, and bone were scattered, however, and Trevize felt his stomach heave.
The dogs started back, some having been bombarded with uncomfortably warm fragments. That was only a momentary hesitation, however. They crowded against each other suddenly, in order to eat what had been provided. Trevize felt his sickness increase. He was not frightening them; he was feeding them. At that rate, they would never leave. In fact, the smell of fresh blood and warm meat would attract still more dogs, and perhaps other smaller predators as well.
A voice called out, “Trevize. What-”
Trevize looked outward. Bliss and Pelorat had emerged from the ruins. Bliss had stopped short, her arms thrown out to keep Pelorat back. She stared at the dogs. The situation was obvious and clear. She had to ask nothing.
Trevize shouted, “I tried to drive them off without involving you and Janov. Can you hold them off?”
“Barely,” said Bliss, not shouting, so that Trevize had trouble hearing her even though the dogs’ snarling had quieted as though a soothing soundabsorbent blanket had been thrown over them.
Bliss said, “There are too many of them, and I am not familiar with their pattern of neuronic activity. We have no such savage things on Gaia.”
“Or on Terminus. Or on any civilized world,” shouted Trevize. “I’ll shoot as many of them as I can and you try to handle the rest. A smaller number will give you less trouble.”
; “No, Trevize. Shooting them will just attract others.-Stay behind me, Pel. There’s no way you can protect me.-Trevize, your other weapon.”
“The neuronic whip?”
“Yes. That produces pain. Low power. Low power!”
“Are you afraid of hurting them?” called out Trevize in anger. “Is this a time to consider the sacredness of life?”
“I’m considering Pel’s. Also mine. Do as I say. Low power, and shoot at one of the dogs. I can’t hold them much longer.”
The dogs had drifted away from the tree and had surrounded Bliss and Pelorat, who stood with their backs to a crumbling wall. The dogs nearest the two made hesitant attempts to come closer still, whining a bit as though trying to puzzle out what it was that held them off when they could sense nothing that would do it. Some tried uselessly to scramble up the wall and attack from behind.
Trevize’s hand was trembling as he adjusted the neuronic whip to low power. The neuronic whip used much less energy than the blaster did, and a single power-cartridge could produce hundreds of whip-like strokes but, come to think of it, he didn’t remember when he had last charged this weapon, either.
It was not so important to aim the whip. Since conserving energy was not as critical, he could use it in a sweep across the mass of dogs. That was the traditional method of controlling crowds that showed signs of turning dangerous.
However, he followed Bliss’s suggestion. He aimed at one dog and fired. The dog fell over, its legs twitching. It emitted loud, high-pitched squeals.
The other dogs backed away from the stricken beast, ears flattening backward against their heads. Then, squealing in their turn, they turned and left, at first slowly, then more rapidly, and finally, at a full race. The dog who had been hit, scrambled painfully to its legs, and limped away whimpering, much the last of them.
The noise vanished in the distance, and Bliss said, “We had better get into the ship. They will come back. Or others will.”
