These were long thin corpse-colored worms with hairy heads; beetles colored a hard blue and armed with huge mandibles; long-nosed shrew-like beasts with saberteeth; pale yellow scorpions; bright scarlet-and-midnight-black snakes with tiny horns on top of their triangular heads; many-legged soft-bodied dozen-antennaed long-bodied centipedish creatures which emitted a stinking gas with a loud explosion when startled; and a host of other repulsive animals. The great broken chunks of bark, lying everywhere in the dimness like boulders left behind by the retreat of a glacier, were crowded with the venomous verminous life.

  Around the jagged slabs grew tall slender branchless plants which produced a heart-shaped greenish-yellow berry that sprouted from cracks in the horny shells of the plants. There was also a thick slimy weed that projected a foot or two above the muddy water or the watery mud underfoot. Above this there sometimes flapped a broad-winged insect with body and wings the color of the skin of a man just dead, and its head was white with two round black markings and a down-curving black mark below the two markings, so that its face was that of a skull. It flew by silently, sometimes just touching a member of the party with the tips of its wings and causing that person to jump. But all motion and noise were subdued. The people talked very quietly, often whispering, and they did not laugh. Their feet sank into the water and the mud beneath and were pulled out slowly, almost apologetically, so that sucking sounds were slow and soft. The people huddled together, and no one wanted to step aside into the bushes or behind the tall pale gray-blue stalks to attend to their needs.

  Ulysses had thought, at first, that he would keep to the swamp. Though the going was slow and rough, this place seemed more desirable than the area above, where there were too many sentient enemies. But one day and one night among the Feet of Wurutana were enough for him and more than enough for his people. The next morning, when he almost jumped a foot as a blood-colored frog leaped off a slab of bark onto his shoulder and then into the ankle-deep water, he decided that he could not take much more. They had tried to sleep on a piece of bark as big as a small chateau. But all night long they had been disturbed by the creatures which crawled out of the holes in the bark and by the weird sounds of the swamp animals.

  He decided that he would lead them back up the nearest inviting branch. They had to skirt a broad area which seemed to be filled with quicksand pools, so it was not until noon that they reached a rough-surfaced column that dived from the heights into the swamp. Thankfully, they began clambering up it, and by dusk they had reached a promising horizontal portion of a branch. This contained a riverlet which, however, looked poisonous. Its water was carmine.

  Ulysses examined it and found that the color came from millions of tiny creatures, each of which was so small it was almost invisible when isolated. Ghlikh, who had decided to talk by then, said that these animals spawned once a year. He did not know where they came from or where they went. The waters of the riverlets and the pools would remain red for about a week and then would become clear. In the meantime, they served as food for the fish, birds and beasts in the jungle. He recommended making a soup of them.

  Ulysses took his recommendation, but he made Ghlikh drink the soup first. After several hours went by with no bad results to the bat-man, Ulysses gave the go-ahead. He drank a gourdful and found the soup very rich and tasty. For the next few days, as they poled their rafts, they ate merely by scooping up the carmine animals from the water. Not having to stop to hunt made their progress far swifter. They traversed approximately fifty miles, climbing down three cataracts, before they reached the lowest level of the riverlet. By then the carmine animals had disappeared.

  When they climbed up again, Ulysses, acting partly on a whim and partly on curiosity, led them as high as they could go. The climb took three days up the gnarled and fissured side of the vertical trunk. At night, they slept on a projection of bark big enough to form a ledge to hold the entire party. The third day, they climbed through the clouds and only broke free of them toward evening. But in the morning the clouds were gone, and they could see into the abyss. They were at least ten thousand feet up. The trunk continued to rise for another two or three thousand feet, but there was no sense in their climbing any higher. This was as high as the branches grew. This branch was a bonanza; it seemed to go on forever, and its downward slope was very gentle.

  A spring welled out at the junction of branch and trunk, and more springs added to the bulk of the riverlet so that, a mile away, it became navigable.

  Every mile or so, the branch extended a vertical part which went all the way to the bottom—as far as they could determine—or else joined with another branch below.

  To prevent the bat-men from trying to fly away, Ulysses had punched holes in the membranes of their wings and tied them together with thin strings of gut. He had forced them to climb up the trunk by themselves, since their weight was too much for anyone to bear on that extended climb. They had been in the middle of the line that crawled up the craggy barky cliff so that they could not try to climb off. They were so light, they could climb much faster than even the agile Wufea.

  Ulysses ordered camp made. They would rest for several days, hunt and scout around. He hoped that he could find another hole in a trunk and so get a chance to experiment with the communication-membrane inside. Ever since his experience with the Wuggruds, he had looked for other holes. He was sure that these must exist by the many thousands, but he had seen none. They were everywhere, according to the bat-men. It was frustrating to know this and yet be unable to find them. However, he was also sure that each hole would be guarded by the bear-like Wuggrud or leopard-like Khrauszmiddum. He could not really afford another encounter with them if they outnumbered his people. But he chafed. If only he could get to a communication-membrane. By now he knew the code. The language was the trade language, and the code was similar to Morse in that it used a combination of long and short pulses.

  He had gotten that out of Ghlikh during the nights when everybody should have been resting from the day’s labors. Khyuks had steadfastly refused to tell him the code. In fact, Khyuks refused even to admit that there was such a thing as a code. But Ghlikh was another person. His threshold of pain was lower, or his strength of character was less. Or he was more intelligent than Khyuks and realized that he would have to break sometime. So why not tell now and save himself much pain for nothing?

  Khyuks cursed Ghlikh for a traitor and a spineless gutless coward, and Ghlikh said that if he did not shut his mouth he would kill him at the first chance. Khyuks replied that he would kill Ghlikh the first chance he got.

  Though Ghlikh did reveal the code, he did not—or could not—reveal the location of the central base of his people. He swore that he had to be high enough above The Tree to see certain navigational checkmarks that would eventually guide him to the base. These marks were high trunks which grew leaves in a pattern that could be determined only by someone about two thousand feet above them. They might even be under one at this moment, but he could not tell from below.

  Ulysses shrugged this disappointment off. He had no plans for attacking the base even if he knew its location. He lacked the force for an attack. But he would have liked to know where it was so that when he did have enough force, he could attack it. He would find out, one way or another.

  He was sitting with his back against a comparatively smooth slab of loosened bark, a big fire about ten feet in front of him. It was almost night. Below, it was night. The sky was still blue, and faraway clouds were touched with pink, light green and a darkening gray. The cries and screams of hunting animals and the hunted wafted up like almost forgotten nightmares, they were so faint. The two bat-men were near him, sitting side by side but not speaking or even looking at each other. The Wufea, Wagarondit and Alkunquib were around six large fires. Guards were posted out on the branch and also out of sight on bark ledges on the sides of the branch. The mouthwatering odor of roasting meat and fish was everywhere. A hunting party had gone out onto the branch earlier
and returned with three four-horned, auburn-haired goats, ten large fish (taken from a black-and-gray-spotted cougar-sized cat which had caught them), bags full of ten different types of berries, and three large heavily furred monkeys.

  The hunters had reported that the vegetation on top of the branch consisted mainly of short but thick-bodied fir trees, berry bushes, a knee-high grass which grew out of dirt caught in the fissures, and an ankle-deep moss. The riverlet contained an abundance of fish but no snoligosters or hipporats. The main predators seemed to be the black-and-gray puma, a small bear, and several types of otters. The other animals were the goats and monkeys.

  They ate well that night and slept as close to the fire as they could get without burning. At this height, it got bitter cold after the sun went down.

  In the morning, they ate the remnants of their supper for breakfast and set out to build rafts. They cut down some of the firs, which were only about twenty feet high, and made rafts. And they launched out with good spirits and high hopes.

  For once, they were not disappointed or deceived. The riverlet took them at an easy pace for about thirty miles and then ended in a widening of the branch. Here the riverlet did not hurtle over a ninety-degree bend in a cataract. It just spilled over the sides of the wide area, blocked by an upward bend of the branch. The party disassembled the rafts and carried the poles up the incline, which was at a forty-five-degree angle. Once on top, they found another spring which soon grew into another riverlet. They put their rafts together and let the stream take them. This type of portage was repeated ten times. Eventually, the branch took the longest uninterrupted stretch they had so far experienced. It lasted about sixty miles, and the descent was so gradual that the water just ran out into the swamp. Ulysses estimated that they must have covered about two hundred and fifty miles on the one branch. Ghlikh said that they had been fortunate to find this one. Only a few were like this.

  They climbed up out of the stinking cold wet swamp until they found a promising branch about six thousand feet up. Ten days later, they came to a waterfall, the foot of which was five thousand feet below them. And here The Tree ended.

  Ulysses felt a little dazed and a little unreal. He had gotten so accustomed to the world being one gigantic tree with its many levels of interfused and winding branches, seemingly sky-high trunks and dense vegetation, that he had thought of the world as only—Tree.

  Now before him was a plain that stretched out perhaps fifty or sixty miles and beyond were the tops of mountains. On the other side of the range, if he could believe Ghlikh, was the sea.

  Awina stood beside him, close enough so that her furred hip rubbed against him. Her long black tail moved back and forth, its tip sometimes tickling the back of his legs.

  “Wurutana has spared us,” she said. “I do not know why. But he has his reasons.”

  Ulysses was angered. He said, “Why can’t you think of our success as being due to my powers as a god?”

  Awina started and looked up at him sidewise. Her eyes were enormous, as always, but the pupils had become slits.

  “Your pardon, Lord,” she said. “We owe you much. Without you, of course, we would have perished. Still, you are a small god compared with Wurutana.”

  “Size does not necessarily mean superiority,” he said.

  He was angry, he thought, not because she denied or depreciated his godhood. He certainly was not that insane. It was just that he wanted to get the proper credit for bringing them through. Credit as a human being, even if he was forced to speak in terms of his godhood.

  He wanted Awina, more than anybody, to give him credit. Now, why should he wish that? Why should this beautiful but weird creature, this sentient but nonhuman being, be so important to him?

  On the other hand, he thought, why shouldn’t she? She had been his mainstay from the first day here, she had taught him his first language (in a manner of speaking), she had served him in many capacities, not the least of which was that of morale upholder. And she was very attractive, in a physical sense. It had been so long since he had seen a human being, he had become accustomed to the nonhuman. Awina was a very beautiful female (he almost thought woman).

  Yet, though he was often very fond of her, he sometimes felt repulsed by her. This occurred when she got too close physically. He moved away, and she looked at him with an unfathomable expression. Did she know what he was thinking? Did she correctly interpret his moving away?

  He hoped not. Because if she did, she was intelligent and sensitive enough to know that the avoidance of physical contact was a defense on his part. And she would know, as he knew, why he had to defend himself.

  He shouted at Wulka and the other chiefs. “Let’s go! Follow me down off The Tree! We’ll be on good solid dry ground soon!”

  The descent went well enough, though he had to resist a tendency to hurry. The vast black-gray bulk of The Tree seemed to be even more threatening, now that he was about free of it, than when he had been inside it. But nothing happened; no Wuggrud or Khrauszmiddum boiled out of The Tree to make a final attack.

  However, once they were out on the plain, they would be easily detected by the winged men. It would be best to stay inside the shade of The Tree until nightfall and then move out.

  Fortunately, the ground at the base of the great Tree here was not so swamp-like. Once they had moved away from the branch down which the riverlet had run, they found dry ground. They made their camp on the northward side of a branch which rammed into the earth at a forty-five-degree angle. Ulysses studied the plain, which was covered by a shin-high green-brown grass and was spotted with small stands of an acacia-like tree. There were great herds of grass and leaf eaters out there: horses, antelopes, buffalo, the giraffe-like animal which he thought had evolved from the horse, the elephant-like beast which could have evolved from the tapir, the giant heavily legged rabbit, and the bluish curving-tusked long-legged swine. There were predators, too, the twelve-foot high roadrunner, the cheetah-like leopard, and prides of porcupine-haired lions.

  That night, the party moved out from The Tree. They did not get far because they spent so much time in hunting. At dawn they made small fires inside a stand of acacia and roasted the meat. Then they slept in the shade of the trees while some stood guard.

  The third day, they reached the mountain range. Ghlikh did not even have to be threatened with torture. He volunteered the information about a pass, and so they marched along the mountains for two days until they found the gap. It took two days to get through the mountains. Abruptly, just at dusk, they came around the shoulder of the mountain and there, sparkling far off, was the sea.

  Then the sun was down, and the sky became black. Ulysses felt happy without knowing why. Perhaps it was because the mountain shut off the view of The Tree and the night kept him from seeing anything that reminded him that he was not in his own time and on the Earth on which he had been born. It was true that the stars formed unfamiliar constellations, but he could ignore that. Later, he was unable to ignore the moon. It was too huge and too bluish-green and white-flecked.

  They rose at dawn, ate breakfast and then set off down the slope of the mountain. By dusk they had reached its foot, and the next morning they set out across the relatively flat land for the sea. This was heavily forested at first, but, the second day, they reached an area of many open fields, houses, barns and fences.

  The houses were square buildings, sometimes two-storied, usually built of logs but occasionally of granite blocks, rough-hewn, set in mortar. The barns were part stone, part wood. Ulysses investigated several and found all unoccupied by anything except wild animals. There were plenty of wood and stone figures and some paintings, all primitive, but there were enough human figures to assure him that the artists had been men.

  He used had been because there was no sign of any human body, living or dead.

  Sometimes, he came across a house or barn which had been burned. Whether this was due to accident or war could not be determined.

  The a
nimals that had been in the unburned barns, and in the houses, had either escaped or died of starvation.

  Nowhere was there even a human bone.

  He spoke to Ghlikh. “What has happened here?”

  Ghlikh looked up at him, shrugged his bony shoulders and spread his wings out as far as the string would allow them. “I do not know, Lord! The last time I was here, six years ago, the Vroomaw lived here. Aside from occasional raids by the Vignoom and the Neshgai, they led a peaceful life. Perhaps we will find out what happened here when we get to the main village. Now, if I were to be permitted to fly ahead, I could find out very quickly…”

  He cocked his head and smiled painfully. He could not, of course, be serious about his proposal, and Ulysses did not even comment on it. They were passing their first graveyard at that time, and Ulysses halted the column. He wandered through the yard, examining the headpieces of the graves. These were thick poles carved out of some reddish hardwood with the skulls of various birds and animals at the tops. There were no other means of identification on the graves, and Ghlikh and Khyuks did not know what the skulls were supposed to mean.

  The column resumed its march down the narrow dirt road. The farms became more numerous, but all were deserted. “Judging from the state of decay of the buildings and of the growth of vegetation around them, I’d say they were abandoned about a year,” Ulysses said. “Maybe two years.” Ghlikh told him that the Vroomaw were the only human beings of whom he knew, except those who were the slaves of the Neshgai, of course. In fact, the Vroomaw may have been descended from the Neshgai’s runaway slaves. On the other hand, the Neshgai may have gotten their slaves from captured Vroomaw. In either event, the Vroomaw lived in an area about a hundred miles square and had a population of about forty-five thousand. There were three main villages of about five thousand citizens each, and the rest lived on farms or hunted. They had had some trade with the Dhulhulikh and with the Pauzaydur. The latter were, according to Ghlikh, a people who lived in the sea, not on it. They were a sort of porpoise-centaur, if Ulysses could believe Ghlikh’s descriptions.
