Winter in Eden

the ponderous creature swam aside to avoid a floating tree that was sweeping down the river in their direction. A forest giant that had been undercut by the flood until it had toppled in. Birds flew up from its still-green foliage as it drifted majestically by them. Under Elem's guidance the uruketo turned again and drew up to the neck of land that was to be their city.

    Ambalasi climbed down first and splashed ashore. The ground was covered with yellowed, dead shrubbery, with the bare branches of the dead trees stark above. Ambalasi made a sharp sign of satisfaction.
    "The beetles will soon take care of the trunks and stumps. Put your Daughters to work pulling down branches and small trees. Throw everything into the river. Then we will inspect the barrier of thorns."
    Ambalasi led the way, walking slowly in the heat. Before they reached the green wall they had to stop in the meager shadow of a skeletal tree to cool before they could go on.
    "Hot," Enge said with some difficulty, her jaw thrown wide.
    "Of necessity, since we are precisely on the equator, a geographical term you would not be acquainted with."
    "The place on the surface of a sphere equidistant from the poles that mark the axis of rotation." Enge was looking at the barrier so missed Ambalasi's gesture of irritation. "In my attempts to understand Ugunenapsa's works I discovered that her philosophy was based in part upon her study of certain natural sciences. So I emulated her fine example…"
    "Emulate my fine example and let us keep walking. We must be absolutely sure there are no breaks in the barrier. Come."
    As they walked along beside the wall of flat leaves and sharp thorns, Ambalasi reached in among the branches to remove ripe seed pods, which she gave to Enge to carry. When they reached the riverbank Ambalasi pointed out the gap between the barrier and the water.
    "Always this way at the interface," she said. "I'll plant more seeds here, also these seeds for thick shrubs that root in the water. Hold them for me."
    The elderly scientist kicked grooves in the mud with a practiced swipe of the claws on one foot while balancing on the other, then bent over, puffing and complaining, to plant the seeds.
    Enge looked out into the river to the place further down the bank where a small sidewater joined the larger body of the great stream. Something moved there, swimming into the river, a large fish of some kind. She looked with interest as another one followed, emerging from the water for an instant.
    "More seeds," Ambalasi said. "A sudden attack of deafness," she added with irritation when she turned to see Enge standing in silence, looking out at the river. "What is the matter?" she asked when there was still no response.

    "There in the water, I saw it, gone now." She spoke with modifiers of such grave importance that Ambalasi turned at once, looking, seeing nothing.
    "What was it?"
    Enge turned back to the scientist with motions of life and death importance. Hesitating in silence before she spoke.
    "I have now thought deeply and have considered all living creatures that I know that bear a resemblance.
    There is none it could possibly be confused with. The first one I saw unclearly, it could have been anything. The second put its head above the water. I saw it. I am not mistaken. It was there."
    "Desire for explanation," Ambalasi said testily in the silence that followed. Enge faced her, still in silence and immobility, looked long into her eyes before she spoke.
    "I realize the importance of what I am about to say. But I make no mistake.
    "There, in the stream, I saw a young elininyil."
    "Impossible. We are the first Yilanè to reach this place; there are no males so no eggs to hatch, no young to enter the sea, no elininyils to grow to fargi. Impossible. Unless…"
    It was Ambalasi's turn to grow silent and rigid, with just shadows of thoughts rippling her muscles. It was a long time before she spoke.
    "It is not impossible. When I spoke just now I was speaking with species specific ethnocentricity.
    Because we Yilanè are at the summit of the ecological pyramid we automatically assume—I automatically assume—that we are alone there, something special and singular. Do you know what I am saying?"
    "No. Personal ignorance of technical concepts."
    "Understandable. I will explain. Distant Entoban* is ours—our cities there stretch through all the habitable areas between the oceans. But
