Out from behind a thicket of glowing mimosa appeared a monstrous bird, some ten or twelve feet in height, lifting its feet very high in a swift but noiseless and curiously delicate stride. Its dark plumage was more like long, stringy hair than feathers. Its build was something like that of a gigantic cassowary, but its thighs and long blue shanks were proportionately more massive. Its neck was long, but immensely muscular to support the enormous head, which was larger than that of a horse, and armed with a huge, hooked, rending, vulture's beak. The apparent length of this terrible head was increased by a pointed crest of blood-red feathers, projecting straight back in a line with the fore-part of the skull and the beak. The crawling figure of Mawg was still a good hundred paces from the unsuspecting Grom, when the great bird overtook it. A-ya, watching from her tree-top, clutched a branch and held her breath. Mawg's ears caught a sound behind him, and he glanced around sharply. With a scream, he bounded to his feet. But it was too late. Before he could either strike or flee, he was beaten down again, with a smash of that pile-driving beak. The bird planted one huge foot on its victim's loins, gripped his head in its beak, and neatly snapped his neck. Then it fell greedily to its hideous meal. At Mawg's scream of terror, Grom had turned and rushed to the rescue, swinging his club. But before he had covered half the distance, he saw that the monster had done its work; and he hesitated. He was too late to help the victim. And he knew the mettle of this ferocious bird, almost as much to be dreaded, in single combat, as the saber-tooth itself. At his approach, the bird had lifted its dripping beak, half turned, and stood gripping the prey with one foot, swaying its grim head slowly and eyeing him with malevolent defiance. Still he hesitated, fingering his club; for the insolence of that challenging stare made his blood seethe. Then came A-ya's voice from the tree-top, calling him. "Come away!" she cried. "It was Mawg." Whereupon he turned, with the content of one who sees all old scores cleanly wiped out together, and went back to gather his ripe plantains. The peril of Mawg being thus removed from their path, they journeyed more swiftly; and when the next new moon was a thin white sickle in the sky, just above the line of saw-toothed hills, they came safely back to the comfortable caves and the clear-burning watch-fires of their tribe.
