These, he thought, were the normal, healthy animals who had won, for the moment, their battle for existence and in a few days more would go outward and onward into the waiting world. Their destinations were the home, the school, the strife of living, the competition for fame and possessions. Among these were some who would taste success and suffer failure; who, barring casualty, would enjoy youth, accept middle age, and grow old sadly. These were those for whom more powerful and glossier automobiles would be designed, in whose service aircraft would wing faster and farther, whose every whim and appetite would be wooed by others of their kind with wares to market. These were some who would face the unknown future, most with misgiving, many bravely, a few craven. Some here, perhaps, might breach the barriers of outer space; others with the gift of tongues might move their fellow men to anger or despair. Most, within twenty years, would fulfill their physical maturity, obeying, but never understanding, the same primeval craving to copulate which had sown their seed and brought them, mewling, puking, here. But for now these were the victors—the born and urgent. Their first and greatest barrier was down, the other battles yet to come.
