Return to Eden by Harry Harrison

mouth opened. Then snapped shut since, in the name of science, she needed this specimen intact for dissection.
    "It shall be known as naeb because of its beak. Now—show me what else you have brought back."
    Ambalasei never ceased to be amazed at the quantity of new species that this continent held. It was to be expected, but was still pleasure magnified many degrees. A beetle bigger than her hand, tiny ustuzou, butterflies, a bewildering array. "Most satisfactory. Into the preserving containers—they have been exposed to the air long enough now. We will have a feast of discovery when we return. Which will be far too soon."
    Setessei caught the overtones of Daughters/depression behind her statements and quickly went to get a water-fruit that had been cooling in the river. Ambalasei drank gratefully but would not be turned aside from her morbid preoccupations.
    "Exploration and pleasures at an end: depressing confrontations to come. I have refrained from thinking about what we will find when we get back. I consider it now since when the uruketo returns—so do we."
    "Interests of science/explorations incomplete," Setessei said temptingly. Ambalasei signed a regretful negative.
    "Nothing would give me greater pleasure than to continue our scientific investigations. But I fear for the city that I have grown, that is now left in the hands of those total incompetents. I forced realities upon them—then left to see if they could solve the problems their own way in my absence. Do you think they have done that? I agree, highly unlikely. Now, are my eyes dimming with age or is that the uruketo returning?"
    "Great Ambalasei's eyesight is like that of a young fargi. They return."
    "Excellent. Prepare your samples at once so they can be loaded aboard before darkness of night. I have kept count of the days and the landmarks. We will be going downstream now, moving with the current. If we leave at dawn we will be at Ambalasokei during daylight tomorrow."
    "We are that close?"
    "No—but the river flows that swiftly."
    As befitted her status, Ambalasei rested at ease while the others labored to preserve the specimens. The enteesenat surged towards the riverbank, leaping high in the water. They were fine, intelligent beasts, a pleasure to watch. The uruketo came steadily on behind them, slowing and stopping with its beak resting on the shore. Elem herself came down from the high fin to aid Ambalasei in boarding. The creature's bill was slippery and gave little purchase to her claws. Once safe on the wide back she rested before beginning the climb to the top of the fin.
    "The creature is fed?" she asked.
    "More than adequate. The enteesenat found many large eels, not as large as the ones we catch, but appreciable in size. The uruketo seemed to take pleasure in consuming them."
    "You can actually understand responses from this brainless creature?"
    "One learns by long association and observation. There is great satisfaction and skill in doing this, satisfaction of the kind I sometimes feel…"
    Elem stopped in confusion, registered apologies, her crest flaming orange then red. Ambalasei signed accepted/understood.
    "You were overwhelmed by the pleasures of command/understanding. I do not take offense. I take note of the fact that in the many days we have been away from the city this is your first lapse, the first time you have even considered mentioning the unmentionable in my presence. But now—speak the name aloud.
    Ugunenapsa!"
    "Thank you, a pleasure to hear it…
    "Not to me. I only say it now to accustom my ear to its coarse sound. Ugunenapsa. How it grates on the nerve endings. We leave in the morning, reach the city the same day. That is why I permit the lapse. A small abomination compared to the ones that I will hear tomorrow."
    Elem signed hopefulness. "Perhaps all is well."
    Ambalasei answered with a rude sound. "Knowing your fellow Daughters as you do—do you really think that is what will have happened?"
    Elem was too wise to
