their journey. For their course, Burl depended entirely upon chance. He avoided the direction of the river, however, and the path along which he had returned to his people. He knew the red mushrooms grew there. Purely by accident he set his march toward the west, and walked cautiously on, his tribesfolk following him fearfully. Burl walked ahead, his spear held ready. He made a figure at once brave and pathetic, venturing forth in a world of monstrous ferocity and incredible malignance, armed only with a horny spear borrowed from a dead insect. His velvety cloak, made from a moth's wing, hung about his figure in graceful folds, however, and twin golden plumes nodded jauntily from his forehead. Behind him the nearly naked people followed reluctantly. Here a woman with a baby in her arms, there children of nine or ten, unable to resist the Instinct to play even in the presence of the manifold dangers of the march. They ate hungrily of the lumps of mushroom they had been ordered to carry. Then a long-legged boy, his eyes roving anxiously about in search of danger followed. Thirty thousand years of flight from every peril had deeply submerged the combative nature of humanity. After the boy came two men, one with a short spear, and the other with a club, each with a huge mass of edible mushroom under his free arm, and both badly frightened at the idea of fleeing from dangers they knew and feared to dangers they did not know and consequently feared much more. So was the caravan spread out. It made its way across the country with many deviations from a fixed line, and with many halts and pauses. Once a shrill stridulation filled all the air before them, a monster sound compounded of innumerable clickings and high-pitched cries. They came to the tip of an eminence and saw a great space of ground covered with tiny black bodies locked in combat. For quite half a mile in either direction the earth was black with ants, snapping and biting at each other, locked in vise-like embraces, each combatant couple trampled under the feet of the contending armies, with no thought of surrender or quarter. The sound of the clashing of fierce jaws upon horny armor, the cries of the maimed, and strange sounds made by the dying, and above all, the whining battle-cry of each of the fighting hordes, made a sustained uproar that was almost deafening. From either side of the battle-ground a pathway led back to separate ant-cities, a pathway marked by
