Saying that and thinking of it goads me to go down the hill again. We designated a latrine rock a few hundred meters away, in sight of the cave entrance but with no obvious path leading here, to throw them off our scent at least temporarily. I will not talk while going there. They also have acute hearing.

  Back. Going too often and with too little result. Diet mostly raw meat in small amounts. Only warm place on my body is the hot and itching anus. No proper hygiene in the Stone Age. Just find a smooth rock. I can feel my digestive tract flourishing with worms and bugs. No evidence yet, though, nor blood. Carlos Fleming started passing blood, and two days later something burst and he died in a rush of it. We covered his body with stones. Ground too frozen for grave-digging. He was probably uncovered and eaten.

  It can’t be the diet. On Earth I paid high prices for raw meat and fish and never suffered except in the wallet. I’m afraid it may be a virus. We all are, and we indulge in discreet copromancy, the divining of future events through the inspection of stools. If there is blood your future will be short.

  Perhaps it was stress. We are under unusual stress. But I stray.

  It was specifically my study of Eskimos that impressed the assigning committee. Eskimos were small bands of hearty folk who lived in the polar regions of North America. Like the Plathys, they were anagricultural carnivores, preying on herds of large animals, sometimes fishing. The Plathys have no need for the Eskimos’ fishing skills, since the sea teems with life edible and stupid. But they prefer red meat and the crunch of bone, the chewy liver and long suck of intestinal contents, the warm mush of brains. They are likable but not fastidious. And not predictable, we learned to our grief.

  Like the Eskimos, the Plathys relish the cold and become rather dull and listless during the warm season. Sanchrist IV has no axial tilt, thus no “seasons” in the Terran sense, but its orbit is highly elongated, so more than two thirds of its year (three and a half Terran years) is spent in cold. We identified six discrete seasons: spring, summer, fall, winter, dead winter, and thaw. The placid sea gets ice skim in mid-fall.

  If you are less than totally ignorant of science, you know that Sanchrist IV is one of the very few planets with not only Earthlike conditions but with life forms that mimic our own patterns of DNA. There are various theories explaining this coincidence, which cannot be coincidence, but you can find them elsewhere. What this meant in terms of our conduct as xenologists was that we could function with minimal ecological impact, living off the fat of the land—and the blood and flesh and marrow, which did require a certain amount of desensitization training. (Less for me than for some of the others, as I’ve said, since I’ve always had an atavistic leaning toward dishes like steak tartare and sushi.)

  Satellite observation has located 119 bands, or families, of Plathys, and there is no sign of other humanoid life on the planet. All of them live on islands in a southern subtropical sea—at least it would be subtropical on Earth—a shallow sea that freezes solid in dead winter and can be walked over from late fall to early thaw. During the warm months, on those occasions when they actually stir their bones to go someplace, they pole rafts from island to island. During low tide, they can wade most of the way.

  We set up our base in the tropics, well beyond their normal range, and hiked south during the late summer. We made contact with a few individuals and small packs during our month-long trek but didn’t join a family until we reached the southern mountains.

  The Plathys aren’t too interesting during the warm months, except for the short mating season. Mostly they loll around, conserving energy, living off the meat killed during the thaw, which they smoke and store in covered holes. When the meat gets too old, or starts running out, they do bestir themselves to fish, which takes little enough energy. The tides are rather high in summer and fall, and all they have to do is stake down nets in the right spots during high tide. The tide recedes and leaves behind flopping silver bounty. They grumble and joke about the taste of it, though.

  They accepted our presence without question, placidly sharing their food and shelter as they would with any wayfaring member of another native family. They couldn’t have mistaken us for natives, though. The smallest adult Plathy weighs twice as much as our largest. They stand about two and a half meters high and span about a meter and a half across the shoulders. Their heads are more conical than square, with huge powerful jaws: a mouth that runs almost ear to ear. Their eyes are set low, and they have mucous-membrane slits in place of external ears and noses. They are covered with sparse silky fur, which coarsens into thick hair on their heads, shoulders, armpits, and groins (and on the males’ backs). The females have four teats defining the corners of a rectangular slab of lactiferous fatty tissue. The openings we thought were their vaginas are almost dorsal, with the cloacal openings toward the front. The male genitals are completely ventral, normally hidden under a mat of hair. (This took a bit of snooping. In all but the hottest times and mating season, both genders wear a “modest” kilt of skin.)

  We had been observing them about three weeks when the females went into estrus—every mature female, all the same day. Their sexuality was prodigious.

  Everybody shed their kilts and went into a week-long unrelenting spasm of sexual activity. There is nothing like it among any of the sentient cultures—or animal species!—that I have studied. To call it an orgy would be misleading and, I think, demeaning to the Plathys. The phenomenon was more like a tropism, in plants, than any animal or human instinct. They quite simply did not do anything else for six days.

  The adults in our family numbered eighty-two males and nineteen females (the terrible reason for the disparity would become clear in a later season), so the females were engaged all the time, even while they slept. While one male copulated, two or three others would be waiting their turn, prancing impatiently, masturbating, sometimes indulging in homosexual coupling. (“Indulging” is the wrong word. There was no sense that they took pleasure in any sexual activity; it was more like the temporary relief of a terrible pressure that quickly built up again.) They attempted coupling with children and with the humans of my expedition. Fortunately, for all their huge strength they are rather slow and, for all the pressure of their “desire,” easily deflected. A kick in the knee was enough to send them stumping off toward someone else.

  No Plathys ate during the six days. They slept more and more toward the end of the period, the males sometimes falling asleep in the middle of copulation. (Conversely, we saw several instances of involuntary erection and ejaculation while sleeping.) When it was finally over, everyone sat around dazed for a while, and then the females retired to the storage holes and came back with armloads of dried and smoked meat and fish. Each one ate a mountain of food and fell into a coma.

  There are interesting synchronies involved. At other times of the year, this long period of vulnerability would mean extinction of the family or of the whole species, since they evidently all copulate at the same time. But the large predators from the north do not swim down at that time of year. And when the litters were dropped, about 500 days later, it would be not long after the time of easiest food gathering, as herds of small animals migrated north for warmth.

  Of course we never had a chance to dissect a Plathy. It would have been fascinating to investigate the internal makeup that impels the bizarre sexual behavior. External observation gives some hint as to the strangeness. The vulva is a small opening, a little over a centimeter in extent, that stays sealed closed except when the female is in estrus. The penis, normally an almost invisible nub, becomes a prehensile purple worm about twenty centimeters long. No external testicles; there must be an internal reservoir (quite large) for seminal fluid.

  The anatomical particulars of pregnancy and birth are even more strange. The females become almost immobilized, gaining perhaps fifty percent in weight. When it comes time to give birth, the female makes an actual skeletal accommodation, evidently similar to the way a snake unhinges its jaw when ingesting large p
rey. It is obviously quite painful. The vulva (or whatever new name applies to that opening) is not involved; instead, a slit opens along the entire perineal area, nearly half a meter long, exposing a milky white membrane. The female claws the membrane open and expels the litter in a series of shuddering contractions. Then she pushes her pelvic bones back into shape with a painful grinding sound. She remains immobile and insensate for several days, nursing. The males bring females food and clean them during this period.

  None of the data from the first expedition had prepared us for this. They had come during dead winter and stayed one (Terran) year, so they missed the entire birth cycle. They had noted that there were evidently strong taboos against discussing sexual matters and birth. I think “taboo” is the wrong word. It’s not as if there were guilt or shame associated with the processes. Rather, they appear to enter a different state of consciousness when the females are in heat and giving birth, a state that seems to blank out their verbal intelligence. They can no more discuss their sexuality than you or I could sit and chat about how our pancreas was doing.

  There was an amusing, and revealing, episode after we had been with the family for several months. I had been getting along well with Tybru, a female elder with unusual linguistic ability. She was perplexed at what one of the children had told her.

  The Plathys have no concept of privacy; they wander in and out of each other’s maffas (the yurtlike tents of hide they use as shelter) at any time of the day or night, on random whim. It was inevitable that sooner or later they would observe humans having sex. The child had described what she’d seen fairly accurately. I had tried to explain human sexuality to Tybru earlier, as a way to get her to talk about that aspect of her own life. She would smile and nod diagonally through the whole thing, an infuriating gesture they normally use only with children prattling nonsense.

  This time I was going to be blunt. I opened the maffa flap so there was plenty of light, then shed my kilt and got up on a table. I lay down on my back and tried to explain with simple words and gestures what went where and who did what to whom, and what might or might not happen nine months later.

  She was more inclined to take me seriously this time. (The child who had witnessed copulation was four, pubescent, and thus too old to have fantasies.) After I explained she explored me herself, which was not pleasant, since her four-fingered hand was larger than a human foot, quite filthy, and equipped with deadly nails.

  She admitted that all she really understood was the breasts. She could remember some weeks of nursing after the blackout period the female language calls “(big) pain-in-hips.” (Their phrase for the other blackout period is literally “pain-in-the-ass.”) She asked, logically enough, whether I could find a male and demonstrate.

  Actually, I’m an objective enough person to have gone along with it, if I could have found a man able and willing to rise to the occasion. If it had been near the end of our stay, I probably would have done it. But leadership is a ticklish thing, even when you’re leading a dozen highly educated, professionally detached people, and we still had three years to go.

  I explained that the most-elder doesn’t do this with the men she’s in charge of, and Tybru accepted that. They don’t have much of a handle on discipline, but they do understand polity and social form. She said she would ask the other human females.

  Perhaps it should have been me who did the asking, but I didn’t suggest it. I was glad to get off the hook, and also curious as to my people’s reactions.

  The couple who volunteered were the last ones I would have predicted. Both of them were shy, almost diffident, with the rest of us. Good field workers but not the sort of people you would let your hair down with. I suppose they had better “anthropological perspective” on their own behavior than the rest of us.

  At any rate, they retired to the maffa that was nominally Tybru’s, and she let out the ululation that means “All free females come here.” I wondered whether our couple could actually perform in a cramped little yurt filled with sweaty giants asking questions in a weird language.

  All the females did crowd into the tent, and after a couple of minutes a strange sound began to emanate from them. At first it puzzled me, but then I recognized it as laughter! I had heard individual Plathys laugh, a sort of inhaled croak—but nineteen of them at once was an unearthly din.

  The couple was in there a long time, but I never did find out whether the demonstration was actually consummated. They came out of the maffa beet-red and staring at the ground, the laughter behind them not abating. I never talked to either of them about it, and whenever I asked Tybru or the others, all I got was choked laughter. I think we invented the dirty joke. (In exchange, I’m sure that Plathy sexuality will eventually see service in the ribald metaphor of every human culture.)

  But let me go back to the beginning.

  We came to Sanchrist IV armed with a small vocabulary and a great deal of misinformation. I don’t mean to denigrate my colleagues’ skill or application. But the Garcia expedition just came at the wrong time and didn’t stay long enough.

  Most of their experience with the Plathys was during deep winter, which is their most lively and civilized season. They spend their indoor time creating the complex sculptures that so impressed the art world ten years ago and performing improvisational music and dance that is delightful in its alien grace.

  Outdoors, they indulge in complicated games and athletic exhibitions. The larders are full, the time of birthing and nursing is well over, and the family exudes happiness, well into the thaw. We experienced this euphoria ourselves. I can’t blame Garcia’s people for their enthusiastic report.

  We still don’t know what happened. Or why it happened. Perhaps if these data survive, the next researchers…

  Trouble.

  Gabriel

  I was having a strange dream of food—real food, cooked—when suddenly there was Maria, tugging on my arm, keeping me away from the table. She was whispering “Gab, wake up!” and so I did, cold and aching and hungry.

  “What’s—” She put her hand on my mouth, lightly.

  “There’s one outside. Mylab, I think.” He had just turned three this winter, and been given his name. We crept together back to the mouth of the cave and both jumped when my ankle gave a loud pop.

  It was Mylab, all right; the fur around one earhole was almost white against the blond. I was glad it wasn’t an adult. He was only about a head taller than me. Stronger, though, and well fed.

  We watched from the cave’s darkness as he investigated the latrine rock, sniffing and licking, circling.

  “Maybe he’s a scout for a hunting party,” I whispered. “Hunting us.”

  “Too young, I think.” She passed me a stone axe. “Hope we don’t have to kill him.”

  “Should we wake the others?”

  “Not yet. Make us easier to scent.” As if on cue, the Plathy walked directly away from the rock and stood, hands on hips, sniffing the air. His head wagged back and forth slowly, as if he were triangulating. He shuffled in a half-circle and stood looking in our direction.

  “Stay still.”

  “He can’t see us in the shadow.”

  “Maybe not.” Their eyesight was more acute than ours, but they didn’t have good night vision.

  Behind us, someone woke up and sneezed. Mylab gave a little start and then began loping toward the cave.

  “Damn it,” Maria whispered. She stood up and huddled into the side of the cave entrance. “You get over there.” I stationed myself opposite her, somewhat better hidden because of a projecting lip of rock.

  Mylab slowed down a few meters from the cave entrance and walked warily forward, sniffing and blinking. Maria crouched, gripping her spear with both hands, for thrusting.

  It was over in a couple of seconds, but my memory of it goes in slow motion: he saw Maria, or sensed her, and lumbered straight for her, claws out, growling. She thrust twice into his chest while I stepped forward and delivered a two-handed blow t
o the top of his head.

  That axe would have cracked a human head from crown to jaw. Instead, it glanced off his thick skull and hit his shoulder, then spun out of my grip.

  Shaking his head, he stepped around and swung a long arm at me. I was just out of range, staggering back; one claw opened up my cheek and the tip of my nose. Blood was spouting from two wounds in his chest. He stepped forward to finish me off and Maria plunged the spear into the back of his neck. The flint blade burst out under his chin in a spray of blood.

  He stood staggering between us for a moment, trying to reach the spear shaft behind him. Two stones flew up from the rear of the cave; one missed, but the other hit his cheek with a loud crack. He turned and stumbled away down the slope, the spear bouncing grotesquely behind him.

  The other four joined us at the cave entrance. Brenda, our doctor, looked at my wound and regretted her lack of equipment. So did I.

  “Have to go after him,” Derek said. “Kill him.”

  Maria shook her head. “He’s still dangerous. Wait a few minutes; then we can follow the blood trail.”

  “He’s dead,” Brenda said. “His body just doesn’t know it yet.”

  “Maybe so,” Maria said, her shoulders slumping sadly. “Anyhow, we can’t stay here. Hate to move during daylight, but we don’t have any choice.”

  “We’re not the only ones who can follow a blood trail,” Herb said. He had a talent for stating the obvious.

  We gathered up our few weapons, the water bladders, and the food sack, to which we had just added five small batlike creatures, mostly fur and bone. None of us looked forward to being hungry enough to eat them.

  The trail was easy to follow, several bright red spatters per meter. He had gone about three hundred meters before collapsing.
