Having picked his route, he straightened up and at a fast dogtrot headed for the nearest tree. He went past it, cut left for another tree, passed it and cut right toward the tree he wanted. He was about fifteen meters from it when something charged him.

He closed the gap with instantaneous apportation which would have done credit to a Ramsbotham hyperfold. He reached the first branch, ten meters above ground, in what amounted to levitation. From there on he climbed more conventionally, digging the spurs into the tree's smooth bark and setting his feet more comfortably on branches when they began to be close enough together to form a ladder.

About twenty meters above ground he stopped and looked down. The branches interfered and it was darker under the trees than it had been out in the open; nevertheless he could see, prowling around the tree, the denizen that had favored him with attention.

Rod tried to get a better view, but the light was failing rapidly. But it looked like... well, if he had not been certain that he was on some uncolonized planet 'way out behind and beyond, he would have said that it was a lion.

Except that it looked eight times as big as any lion ought to look.

He hoped that, whatever it was, it could not climb trees. Oh, quit fretting, Rod!- if it had been able to climb you would have been lunch meat five minutes ago. Get busy and rig a place to sleep before it gets pitch dark. He moved up the tree, keeping an eye out for the spot he needed.

He found it presently, just as he was beginning to think that he would have to go farther down. He needed two stout branches far enough apart and near enough the same level to let him stretch a hammock. Having found such, he worked quickly to beat the failing light. From a pocket of his vest pack he took out his hammock, a web strong as spider silk and almost as thin and light. Using the line around his waist he stretched it, made sure his lashings would hold and then started to get into it.

A double-jointed acrobat with prehensile toes might have found it easy; a slack-wire artist would simply have walked into it and sat down. But Rod found that he needed sky hooks. He almost fell out of the tree.

The hammock was a practical piece of equipment and Rod had slept in it before. His sister had approved it, remarking that it was a better model than the field hammock they gave her girls. "Just don't sit up in your sleep."

"I won't," Rod had assured her. "Anyway, I always fasten the chest belt."

But he had never slung it in this fashion. There was nothing to stand on under the hammock, no tree limb above it close enough to let him chin himself into it. After several awkward and breath-catching attempts he began to wonder whether he should perch like a bird the rest of the night, or drape himself in the notch of a limb. He did not consider spending the night on the ground- not with that thing prowling around.

There was another limb higher up almost directly over the hammock. Maybe if he tossed the end of his line over it and used it to steady himself...

He tried it. But it was almost pitch dark now; the only reason he did not lose his line was that one end was bent to the hammock. At last he gave up and made one more attempt to crawl into the hammock by main force and extreme care. Bracing both hands wide on each side of the head rope he scooted his feet out slowly and cautiously. Presently he had his legs inside the hammock, then his buttocks. From there on it was a matter of keeping his center of gravity low and making no sudden moves while he insinuated his body farther down into the cocoon.

At last he could feel himself fully and firmly supported. He took a deep breath, sighed, and let himself relax. It was the first time he had felt either safe or comfortable since passing through the gate.

After a few minutes of delicious rest Rod located the nipple of his canteen and allowed himself two swallows of water, after which he prepared supper. This consisted in digging out a quarter-kilo brick of field ration, eleven hundred calories of yeast protein, fat, starch, and glucose, plus trace requirements. The label on it, invisible in the dark, certified that it was "tasty, tempting and pleasing in texture," whereas chewing an old shoe would have attracted a gourmet quite as much.

But real hunger gave Rod the best of sauces. He did not let any crumb escape and ended by licking the wrapper. He thought about opening another one, quelled the longing, allowed himself one more mouthful of water, then pulled the insect hood of the hammock down over his face and fastened it under the chest belt. He was immune to most insect-carried Terran diseases and was comfortably aware that humans were not subject to most Outlands diseases, but he did not want the night fliers to use his face as a drinking fountain, nor even as a parade ground.

He was too hot even in his light clothing. He considered shucking down to his shorts; this planet, or this part of this planet, seemed quite tropical. But it was awkward; tonight he must stay as he was, even if it meant wasting a day's ration of water in sweat. He wondered what planet this was, then tried to peer through the roof of the forest to see if he could recognize stars. But either the trees were impenetrable or the sky was overcast; he could see nothing. He attempted to draw everything out of his mind and sleep.

Ten minutes later he was wider awake than ever. Busy with his hammock, busy with his dinner, he had not paid attention to distant sounds; now he became aware of all the voices of the night. Insects buzzed and sang and strummed, foliage rustled and whispered, something coughed below him. The cough was answered by insane laughter that ran raggedly up, then down, and died in asthmatic choking.

Rod hoped that it was a bird.

He found himself straining to hear every sound, near and far, holding his breath. He told himself angrily to stop it; he was safe from at least nine-tenths of potential enemies. Even a snake, if this place ran to such, would be unlikely to crawl out to the hammock, still less likely to attack- if he held still. Snakes, button-brained as they were, showed little interest in anything too big to swalow. The chances of anything big enough to hurt him-and interested in hurting him- being in this treetop were slim. So forget those funny noises, pal, and go to sleep. After all, they're no more important than traffic noises in a city.

He reminded himself of the Deacon's lecture on alarm reaction, the thesis that most forms of death could be traced to the body's coming too urgently to battle stations, remaining too long at full alert. Or, as his sister had put it, more people worry themselves to death than bleed to death. He set himself conscientiously to running through the mental routines intended to produce sleep.

He almost made it. The sound that pulled him out of warm drowsiness came from far away; involuntarily he roused himself to hear it. It sounded almost human... no, it was human-the terrible sound of a grown man crying with heartbreak, the deep, retching, bass sobs that tear the chest.

Rod wondered what he ought to do. It was none of his business and everyone there was on his own-but it went against the grain to hear such agony from a fellow human and ignore it. Should he climb down and feel his way through the dark to wherever the poor wretch was? Stumbling into tree roots, he reminded himself, and falling into holes and maybe walking straight into the jaws of something hungry and big.

Well, should he? Did he have any right not to?

It was solved for him by the sobs being answered by more sobs, this time closer and much louder. This new voice did not sound human, much as it was like the first, and it scared him almost out of his hammock. The chest strap saved him.

The second voice was joined by a third, farther away. In a few moments the peace of the night had changed to sobbing, howling ululation of mass fear and agony and defeat unbearable. Rod knew now that this was nothing human, nor anything he had ever heard, or heard of, before. He suddenly had a deep conviction that these were the stobor he had been warned to avoid.
