of old Tha, will mate with none but the mightiest of hunters. Only so recently as the last darkness, as, beneath the great, equatorial moon, the two had walked hand in hand beside the restless sea she had made it quite plain to Nu, the son of Nu, that not even he, son of the chief of chiefs, could claim her unless there hung at the thong of his loin cloth the fangs of Oo. "Nat-ul," she had said to him, "wishes her man to be greater than other men. She loves Nu now better than her very life, but if Love is to walk at her side during a long life Pride and Respect must walk with it." Her slender hand reached up to stroke the young giant's black hair. "I am very proud of my Nu even now," she continued, "for among all the young men of the tribe there is no greater hunter, or no mightier fighter than Nu, the son of Nu. Should you, single-handed, slay Oo before a grown man's beard has darkened your cheek there will be none greater in all the world than Nat-ul's mate, Nu, the son of Nu."

As the tiny, blood-shot eyes of the primordial beast discovered the man the great head went down, and Ta, ill natured and bellicose progenitor of the equally ill natured and bellicose rhino of the twentieth century, charged the lithe giant who had disturbed his antediluvian meditation. The creature's great bulk and awkward, uncouth lines belied his speed, for he tore down upon Nu with all the swiftness of a thoroughbred and had not the brain and muscle of the troglodyte been fitted by heritage and training to the successful meeting of such emergencies there would be no tale to tell today of Nu of the Niocene. But the young man was prepared, and turning he ran with the swiftness of a hare toward the
