This inroad of the Fire People on the carrot-patch was the beginning of the end, though we did not know it. The hunters of the Fire People began to appear more frequently as the time went by. They came in twos and threes, creeping silently through the forest, with their flying arrows able to annihilate distance and bring down prey from the top of the loftiest tree without themselves climbing into it. The bow and arrow was like an enormous extension of their leaping and striking muscles, so that, virtually, they could leap and kill at a hundred feet and more. This made them far more terrible than Saber-Tooth himself. And then they were very wise. They had speech that enabled them more effectively to reason, and in addition they understood cooperation. We Folk came to be very circumspect when we were in the forest. We were more alert and vigilant and timid. No longer were the trees a protection to be relied upon. No longer could we perch on a branch and laugh down at our carnivorous enemies on the ground. The Fire People were carnivorous, with claws and fangs a hundred feet long, the most terrible of all the hunting animals that ranged the primeval world. One morning, before the Folk had dispersed to the forest, there was a panic among the water-carriers and those who had gone down to the river to drink. The whole horde fled to the caves. It was our habit, at such times, to flee first and investigate afterward. We waited in the mouths of our caves and watched. After some time a Fire-Man stepped cautiously into the open space. It was the little wizened old hunter. He stood for a long time and watched us, looking our caves and the cliff-wall up and down. He descended one of the run-ways to a drinking-place, returning a few minutes later by another run-way. Again he stood and watched us carefully, for a long time. Then he turned on his heel and limped into the forest, leaving us calling querulously and plaintively to one another from the cave-mouths. CHAPTER XVI I found her down in the old neighborhood near the blueberry swamp, where my mother lived and where Lop-Ear and I had built our first tree-shelter. It was unexpected. As I came under the tree I heard the familiar soft sound and looked up. There she was, the Swift One, sitting on a limb and swinging her legs back and forth as she looked at me. I stood still for some time. The sight of her had made me very happy. And then an unrest and a pain began to creep in on this happiness. I started to climb the tree after her, and she retreated slowly out the limb. Just as I reached for her, she sprang through the air and landed in the branches of the next tree. From amid the rustling leaves she peeped out at me and made soft sounds. I leaped straight for her, and after an exciting chase the situation was duplicated, for there she was, making soft sounds and peeping out from the leaves of a third tree.
