After walking for several minutes, the biped stepped across the stream. It then began walking as closely as possible to the wall, meanwhile looking apprehensively at the other side of the tunnel, where they had been walking.

  Lane also looked but could see nothing at which to be alarmed. There was a large opening at the base of the wall which evidently led into a tunnel. This tunnel, he presumed, ran underground into a room or rooms, for many leggers dashed in and out of it. And about a dozen, larger than average, paced back and forth like sentries before the hole.

  When they had gone about fifty yards past the opening, the biped relaxed. After it had led Lane along for ten minutes, it stopped. Its naked hand touched the wall. He became aware that the hand was small and delicately shaped, like a woman's.

  A section of the wall swung out. The biped turned and bent down to crawl into the hole, presenting buttocks and legs femininely rounded, well shaped. It was then that he began thinking of it as a female. Yet the hips, though padded with fatty tissue, were not broad. The bones were not widely separated to make room to carry a child. Despite their curving, the hips were relatively as narrow as a man's.

  Behind them, the plug swung shut. The biped did not turn on her flashlight, for there was illumination at the end of the tunnel. The floor and walls were not of the hard gray stuff nor of packed earth. They seemed vitrified, as if glassed by heat.

  She was waiting for him when he slid off a three-foot high ledge into a large room. For a minute he was blinded by the strong light. After his eyes adjusted, he searched for the source of light but could not find it. He did observe that there were no shadows in the room.

  The biped took off her helmet and suit and hung them in a closet. The door slid open as she approached and closed when she walked away.

  She signaled that he could remove his suit. He did not hesitate. Though the air might be poisonous, he had no choice. His tank would soon be empty. Moreover, it seemed likely that the atmosphere contained enough oxygen. Even then he had grasped the idea that the leaves of the umbrella plants, which grew out of the top of the tubes, absorbed sunlight and traces of carbon dioxide. Inside the tunnels, the roots drew up water from the channel and absorbed the great quantity of carbon dioxide released by the dekapeds. Energy of sunlight converted gas and liquid into glucose and oxygen, which were given off in the tunnels.

  Even here, in this deep chamber which lay beneath and to one side of the tube, a thick root penetrated the ceiling and spread its thin white web over the walls. He stood directly beneath the fleshy growth as he removed his helmet and took his first breath of Martian air. Immediately afterward, he jumped. Something wet had dropped on his forehead. Looking up, he saw that the root was excreting liquid from a large pore. He wiped the drop off with his finger and tasted it. It was sticky and sweet.

  Well, he thought, the tree must normally drop sugar in water. But it seemed to be doing so abnormally fast, because another drop was forming.

  Then it came to him that perhaps this was so because it was getting dark outside and therefore cold. The umbrella trees might be pumping the water in their trunks into the warm tunnels. Thus, during the bitter subzero night, they'd avoid freezing and swelling up and cracking wide open.

  It seemed a reasonable theory.

  He looked around. The place was half living quarters, half biological laboratory. There were beds and tables and chairs and several unidentifiable articles. One was a large black metal box in a corner. From it, at regular intervals, issued a stream of tiny blue bubbles. They rose to the ceiling, growing larger as they did so. On reaching the ceiling they did not stop or burst but simply penetrated the vitrification as if it did not exist.

  Lane now knew the origin of the blue globes he had seen appear from the surface of the garden. But their purpose was still obscure.

  He wasn't given much time to watch the globes. The biped took a large green ceramic bowl from a cupboard and set it on a table. Lane eyed her curiously, wondering what she was going to do. By now he had seen that the second head belonged to an entirely separate creature. Its slim four-foot length of pinkish skin was coiled about her neck and torso; its tiny flat-faced head turned toward Lane; its snaky light blue eyes glittered. Suddenly, its mouth opened and revealed toothless gums, and its bright red tongue, mammalian, not at all reptilian, thrust out at him.

  The biped, paying no attention to the worm's actions, lifted it from her. Gently, cooing a few words in a soft many-voweled language, she placed it in the bowl. It settled inside and looped around the curve, like a snake in a pit.

  The biped took a pitcher from the top of a box of red plastic. Though the box was not connected to any visible power source, it seemed to be a stove. The pitcher contained warm water which she poured into the bowl, half filling it. Under the shower, the worm closed its eyes as if it were purring soundless ecstasy.

  Then the biped did something that alarmed Lane.

  She leaned over the bowl and vomited into it.

  He stepped toward her. Forgetting the fact that she couldn't understand him, he said, "Are you sick?"

  She revealed human-looking teeth in a smile meant to reassure him, and she walked away from the bowl. He looked at the worm, which had its head dipped into the mess. Suddenly, he felt sick, for he was sure that it was feeding off the mixture. And he was equally certain that she fed the worm regularly with regurgitated food.

  It didn't cancel his disgust to reflect that he shouldn't react to her as he would to a Terrestrial. He knew that she was totally alien and that it was inevitable that some of her ways would repel, perhaps even shock him. Rationally, he knew this. But if his brain told him to understand and forgive, his belly said to loathe and reject.

  His aversion was not much lessened by a close scrutiny of her as she took a shower in a cubicle set in the wall. She was about five feet tall and slim as a woman should be slim, with delicate bones beneath rounded flesh. Her legs were human; in nylons and high heels they would have been exciting -- other things being equal. However, if the shoes had been toeless, her feet would have caused much comment. They had four toes.

  Her long beautiful hands had five fingers. These seemed nailless, like the toes, though a closer examination later showed him they did bear rudimentary nails.

  She stepped from the cubicle and began toweling herself, though not before she motioned to him to remove his suit and also to shower. He stared intently back at her until she laughed a short embarrassed laugh. It was feminine, not at all deep. Then she spoke.

  He closed his eyes and was hearing what he had thought he would not hear for years: a woman's voice. Hers was extraordinary: husky and honeyed at the same time.

  But when he opened his eyes, he saw her for what she was. No woman. No man. What? It? No. The impulse to think her, she, was too strong.

  This, despite her lack of mammaries. She had a chest, but no nipples, rudimentary or otherwise. Her chest was a man's, muscled under the layer of fat which subtly curved to give the impression that beneath it... budding breasts?

  No, not this creature. She would never suckle her young. She did not even bear them alive, if she did bear. Her belly was smooth, undimpled with a navel.

  Smooth also was the region between her legs, hairless, unbroken, as innocent of organ as if she were a nymph painted for some Victorian children's book.

  It was that sexless joining of the legs that was so horrible. Like the white belly of a frog, thought Lane, shuddering.

  At the same time, his curiosity became even stronger. How did this thing mate and reproduce?

  Again she laughed and smiled with fleshy pale-red humanly everted lips and wrinkled a short, slightly uptilted nose and ran her hand through thick straight red- gold fur. It was fur, not hair, and it had a slightly oily sheen, like a water-dwelling animal's.

  The face itself, though strange, could have passed for human, but only passed. Her cheekbones were very high and protruded upward in an unhuman fashion. Her eyes were dark blue and quite human
. This meant nothing. So were an octopus' eyes.

  She walked to another closet, and as she went away from him he saw again that though the hips were curved like a woman's they did not sway with the pelvic displacement of the human female.

  The door swung momentarily open, revealed the carcasses of several dekapeds, minus their legs, hanging on hooks. She removed one, placed it on a metal table, and out of the cupboard took a saw and several knives and began cutting.

  Because he was eager to see the anatomy of the dekaped, he approached the table. She waved him to the shower. Lane removed his suit. When he came to the knife and ax he hesitated, but, afraid she might think him distrustful, he hung up the belt containing his weapons beside the suit. However, he did not take off his clothes because he was determined to view the inner organs of the animal. Later, he would shower.

  The legger was not an insect, despite its spidery appearance. Not in the Terrestrial sense, certainly. Neither was it a vertebrate. Its smooth hairless skin was an animal's, as lightly pigmented as a blond Swede's. But, though it had an endoskeleton, it had no backbone. Instead, the body bones formed a round cage. Its thin ribs radiated from a cartilaginous collar which adjoined the back of the head. The ribs curved outward, then in, almost meeting at the posterior. Inside the cage were ventral lung sacs, a relatively large heart, and liver-like and kidney-like organs. Three arteries, instead of the mammalian two, left the heart. He couldn't be sure with such a hurried examination, but it looked as if the dorsal aorta, like some Terrestrial reptiles, carried both pure and impure blood.

  There were other things to note. The most extraordinary was that, as far as he could discern, the legger had no digestive system. It seemed to lack both intestines and anus unless you would define as an intestine a sac which ran straight through from the throat halfway into the body. Further, there was nothing he could identify as reproductive organs, though this did not mean that it did not possess them. The creature's long tubular tongue, cut open by the biped, exposed a canal running down the length of tongue from its open tip to the bladder at its base. Apparently these formed part of the excretory system.

  Lane wondered what enabled the legger to stand the great pressure differences between the interior of the tube and the Martian surface. At the same time he realized that this ability was no more wonderful than the biological mechanism which gave whales and seals the power to endure without harm the enormous pressures a half mile below the sea's surface.

  The biped looked at him with round and very pretty blue eyes, laughed, and then reached into the chopped open skull and brought out the tiny brain.

  "Hauaimi," she said slowly. She pointed to her head, repeated, "Hauaimi," and then indicated his head. "Hauaimi."

  Echoing her, he pointed at his own head. "Hauaimi. Brain."

  "Brain," she said, and she laughed again.

  She proceeded to call out the organs of the legger which corresponded to hers. Thus, the preparations for the meal passed swiftly as he proceeded from the carcass to other objects in the room. By the time she had fried the meat and boiled strips of the membranous leaf of the umbrella plant, and also added from cans various exotic foods, she had exchanged at least forty words with him. An hour later, he could remember twenty.

  There was one thing yet to learn. He pointed to himself and said, "Lane."

  Then he pointed to her and gave her a questioning look.

  "Mahrseeya," she said.

  "Martia?" he repeated. She corrected him, but he was so struck by the resemblance that always afterward he called her that. After a while, she would give up trying to teach him the exact pronunciation.

  Martia washed her hands and poured him a bowlful of water. He used the soap and towel she handed him, then walked to the table where she stood waiting. On it was a bowl of thick soup, a plate of fried brains, a salad of boiled leaves and some unidentifiable vegetables, a plate of ribs with thick dark legger meat, hard-boiled eggs, and little loaves of bread.

  Martia gestured for him to sit down. Evidently her code did not allow her to sit down before her guest did. He ignored his chair, went behind her, put his hand on her shoulder, pressed down, and with the other hand slid her chair under her: She turned her head to smile up at him. Her fur slid away to reveal one lobeless pointed ear. He scarcely noticed it, for he was too intent on the half-repulsive, half heart- quickening sensation he got when he touched her skin. It had not been the skin itself that caused that, for she was soft and warm as a young girl. It had been the idea of touching her.

  Part of that, he thought as he seated himself, came from her nakedness. Not because it revealed her sex but because it revealed her lack of it. No breasts, no nipples, no navel, no pubic fold or projection. The absence of these seemed wrong, very wrong, unsettling. It was a shameful thing that she had nothing of which to be ashamed.

  That's a queer thought, he said to himself. And for no reason, he became warm in the face.

  Martia, unnoticing, poured from a tall bottle a glassful of dark wine. He tasted it. It was exquisite, no better than the best Earth had to offer but as good.

  Martia took one of the loaves, broke it into two pieces, and handed him one. Holding the glass of wine in one hand and the bread in the other, she bowed her head, closed her eyes, and began chanting.

  He stared at her. This was a prayer, a grace-saying. Was it the prelude to a sort of communion, one so like Earth's it was startling?

  Yet, if it were, he needn't be surprised. Flesh and blood, bread and wine: the symbolism was simple, logical, and might even be universal.

  However, it was possible that he was creating parallels that did not exist. She might be enacting a ritual whose origin and meaning were like nothing of which he had ever dreamed.

  If so, what she did next was equally capable of misinterpretation. She nibbled at the bread, sipped the wine, and then plainly invited him to do the same. He did so. Martia took a third and empty cup, spat a piece of wine-moistened bread into the cup, and indicated that he was to imitate her.

  After he did, he felt his stomach draw in on itself. For she mixed the stuff from their mouths with her finger and then offered it to him. Evidently, he was to put the finger in his mouth and eat from it.

  So the action was both physical and metaphysical. The bread and the wine were the flesh and blood of whatever divinity she worshiped. More, she, being imbued with the body and the spirit of the god, now wanted to mingle hers and that of the god's with his.

  What I eat of the god's, I become. What you eat of me, you become. What I eat of you, I become. Now we three are become one.

  Lane, far from being repelled by the concept, was excited. He knew that there were probably many Christians who would have refused to share in the communion because the ritual did not have the same origins or conform to theirs. They might even have thought that by sharing they were subscribing to an alien god. Such an idea Lane considered to be not only narrow-minded and inflexible, but illogical, uncharitable, and ridiculous. There could be but one Creator; what names the creature gave to the

  Creator did not matter.

  Lane believed sincerely in a personal god, one who took note of him as an individual. He also believed that mankind needed redeeming and that a redeemer had been sent to Earth. And if other worlds needed redeeming, then they too would have gotten or would get a redeemer. He went perhaps further than most of his fellow religionists, for he actually made an attempt to practice love for mankind. This had given him somewhat of a reputation as a fanatic among his acquaintances and friends. However, he had been restrained enough not to make himself too much of a nuisance, and his genuine warmheartedness had made him welcome in spite of his eccentricity.

  Six years before, he had been an agnostic. His first trip into space had converted him. The overwhelming experience had made him realize shatteringly what an insignificant being he was, how awe-inspiringly complicated and immense was the universe, and how much he needed a framework within which to be and to become.

&
nbsp; The strangest feature about his conversion, he thought afterward, was that one of his companions on that maiden trip had been a devout believer who, on returning to Earth, had renounced his own sect and faith and become a complete atheist.

  He thought of this as he took her proffered finger in his mouth and sucked the paste off it.

  Then obeying her gestures, he dipped his own finger into the bowl and put it between her lips.

  She closed her eyes and gently mouthed the finger. When he began to withdraw it, he was stopped by her hand on his wrist. He did not insist on taking the finger out, for he wanted to avoid offending her. Perhaps a long time interval was part of the rite.

  But her expression seemed so eager and at the same time so ecstatic, like a hungry baby just given the nipple, that he felt uneasy. After a minute, seeing no indication on her part that she meant to quit, he slowly but firmly pulled the finger loose. She opened her eyes and sighed, but she made no comment. Instead, she began serving his supper.

  The hot thick soup was delicious and invigorating. Its texture was somewhat like the plankton soup that was becoming popular on hungry Earth, but it had no fishy flavor. The brown bread reminded him of rye. The legger meat was like wild rabbit, though it was sweeter and had an unidentifiable tang. He took only one bite of the leaf salad and then frantically poured wine down his throat to wash away the burn. Tears came to his eyes, and he coughed until she spoke to him in an alarmed tone. He smiled back at her but refused to touch the salad again. The wine not only cooled his mouth, it filled his veins with singing. He told himself he should take no more. Nevertheless, he finished his second cup before he remembered his resolve to be temperate.

  By then it was too late. The strong liquor went straight to his head; he felt dizzy and wanted to laugh. The events of the day, his near-escape from death, the reaction to knowing his comrades were dead, his realization of his present situation, the tension caused by his encounters with the dekapeds, and his unsatisfied curiosity about Martia's origins and the location of others of her kind, all these combined to produce in him a half-stupor, half-exuberance.
