Ammonite

The edge of a cloud veiled the sun and shadow raced down one side of the valley, blurring the wide glitter of the Ho to a dull gleam, then ru

Last night she had been exhausted, and the hot swirling torches of the women who escorted her and Ude to the lodge had only smeared the dark with red. She had noticed the roughness of the roof and walls but assumed it was thatching. She had been wrong. The outside of the lodge was alive with greenery. It looked like a small hill nestling amongst the trees. She reached out and touched a pale green leaf. Cool and silky. Another leaf fluttered as a beetle the size of her thumb skittered out of sight. A wirrel shrieked, then another. This time she did not jump.

Curious, she ducked inside the lodge to take another look at the central rib and the branching lateral spars. Branches. The structural skeleton was a skelter tree.

She dressed, then prowled the lodge, picking up the wooden bowls, polished with use, looking under the table, noting the way the underside was not planed but still rough with black bark, the leg joints fastened with wooden pegs. There was a knife on the table, its blade made of a smoky, vitreous substance: olla, named after the flowers that grew over the raw olla beds. She tested it against the hair on her arm. It was extremely sharp. The pitcher of water was made of red‑glazed clay; the cutting slab was stone, like the pestle and mortar. A shelf ran around the lodge at waist height, piled with neatly folded clothes. She ran her hands over them, under them, between them. They were smooth and rough: cotton and canvas, leather and wool. They were warm. Her knuckles bumped on buttons of horn and wood, caught in ties and laces–no cold shock of metal fasteners. The door bar slid back and forth on greased wooden blocks that were glued and pegged into place.

Marghe followed the winding path between lodges toward the river and, she hoped, Lu Wai and Letitia. She popped a memory chip from her wristcom, inserted another, touched RECORD, and continued her notes from the day before. “Holme Valley has a population of about four hundred women and children. Sometime in the next ten days this will swell by another hundred or so as the community north of here drives their herds down from the pastures to winter in the valley. The women of Singing Pastures and those of the valley form two distinct communities. They even use different calendars dictated by different moons: the valley people divide the year into fifteen months of eighteen days each; the women of the pastures reckon with a ten‑month calendar, each month twenty‑seven days long.”

She hit PAUSE. She wished she could spare the time to stay and observe the mingling of the different populations, watch how they interacted. It would be like being able to go back in time and observe the early symbiotic interactions between people from human history on Earth.

A wirrel shrieked. Marghe went very still. This was not Earth; this was Jeep, a planet of alien species, a place where the human template of dual sexes had been torn to shreds and thrown away. This was something new. She knew these people had evolved cultures resting on bases very different from those of any Earth people; she did not know whether that made these women human or something entirely Other.

She shook herself. The question, What was humanity? was as old as the species, one she never expected to answer. She resumed her walk through the trees, but more slowly, thinking and occasionally making notes.

“If skelter trees grow at approximately the same rate as Earth trees, then to shape such a tree into a dwelling place must take forty or more years.” She imagined a family group selecting a tree, bending it, pruning it judiciously as babies were born, girls grew, and old women died. Did the lodge retain its integrity when the tree died? She exited RECORD and looked up botanical records. Skelter trees lasted two hundred years. “The use of such building methods must be indicative of the social temperament of these people: patient, pla

The trees ended a few yards from the river in a grassy slope, hammocked and tufted here and there where it grew over old tree stumps. Marghe wondered whether the tree fellers had used axes with stone or olla blades.

Someone was walking through the trees toward the path she had just left. Color flashed. Marghe recognized the fatigues.

“Lu Wai!” She waved and the Mirror saw her. “How’s Letitia?”

“Angry with herself and a bit shamefaced for making you risk yourself like that. Otherwise, she’s fine. I was coming to see if you’d join us for breakfast.”

“I’m breakfasting with one of the women who farm the biggest field here. Cassil. I hope to trade for some travel rations. But thank you.” She paused. “This thing with Letitia, I gather it’s happened before.”

“More than once.”

“Is it organic?”

“I haven’t been able to find anything.” Lu Wai shrugged. “Which doesn’t mean it’s not there. The diagnostic tools we have are primitive.” She sighed. “But what do I know? I’m only a medic.”

Marghe heard the hours of tests and record‑searching in the Mirror’s voice and could find nothing to say. She watched Lu Wai walk away and wondered if Da

Cassil had hair the red‑brown of strong tea, and gray eyes. She also had a baby on her hip, which, judging by its fair hair and brown eyes, was not hers. She looked tired and utterly human. She spoke slowly and with much repetition for Marghe’s sake.

“What we have isn’t mine or my kith’s to give.”

“But you farm the land?”

Cassil sighed, as though she had tried to explain this many times before and failed. “My kith farms well. Everyone sees that. So the journey women give us more land to work. We work it well, produce more food, leave the land fresh for the next season’s growing. Everyone benefits. We use the food to feed ourselves, and for trata.” The word she used did not mean trade, exactly; it meant trade as the first step on a journey whose outcome was uncertain–an opening gambit in a game that might continue for generations. Trata could be between two people, between two or more kiths, or between several communities. Frequently it was all three, each exchange resonating with another in the web.

The baby squirmed and Cassil switched it to her other hip. “If I give you food, or good boots, a woman might say to me, ‘Cassil, if you had given me that food, I would have made you two fine hangings for your lodge, and given you first pick of my next catch. But you gave it to that stranger woman and neither of us has gained anything from each other. Tell me, Cassil, what did this stranger woman give you in return?’ And what would I say to that?” The baby wriggled again, more determinedly this time. Cassil jigged her up and down, gave her a finger to suck.

Marghe was acutely conscious of her fatigue, the ache in her muscles, as she opened her empty hands. “My kith is large and very powerful.”

Cassil regarded her a moment. “Then why not return to your large and very powerful kith for more supplies?” Because they might not give me any more, because Dormer might not let me go again, Marghe wanted to shout. Because I am utterly alone on this world. She had nobody; no kith, no kin, no community. Da
