Dalgard had already seen, in seeing he knew hot and terrible anger. Out of the filthy mess in which the snake-devils wallowed, something had rolled, perhaps thrown about in play by the unspeakable offspring. A skull, dried scraps of fur and flesh still clinging to it, stared hollow-eyed up at them. At least one merman had fallen prey to the nightmares who ruled the arena. Sssuri hissed and the red rage in his mind was plain to Dalgard. "Once more they deal death here--" His eyes went from the skull to the monsters. "Kill!" The command was imperative and sharp. Dalgard had qualified as a master bowman before he had first gone roving. And the killing of snake-devils was a task which had been set every colonist since their first brush with the creatures. He snapped the cap off the glass splinter point, designed to pin and then break off in the hide so that any clawing foot which tore out an arrow could not rid the victim of the poisonous head. The archer's mark was under the throat where the scales were soft and there was a chance of piercing the skin with the first shot. The growls of the two feeding youngsters covered the snap of the bow cord as Dalgard shot. And he did not miss. The brilliant scarlet feather of the arrow quivered in the baggy roll of flesh. With a scream which tore at the human's eardrums, the snake-devil reared to its hind feet. It made a tearing motion with the banded forearm which scraped across the back of one of its companions. And then it fell back to the blood-stained sand, limp, a greenish foam drooling from its fangs. As the monster that the dead devil had raked roused, Dalgard had his chance for another good mark. And the second scarlet shaft sped straight to the target. But the third creature which had been sleeping belly down on the sand presented only its armored back, a hopeless surface for an arrow to pierce. It had opened its eyes and was watching the now motionless bodies of its fellows. But it showed no disposition to move. It was almost as if it somehow understood that as long as it remained in its present position it was safe. "The small ones--" Dalgard needed no prompting. He picked off easily enough the two half-grown ones. The infants were another problem. Far less sluggish than their huge elders they sensed that they were in danger and fled. One took refuge in the pouch of its now-dead parent, and the others moved so fast that Dalgard found them difficult targets. He killed one which had almost reached an archway and at length nicked the second in the foot, knowing that, while the poison would be slower in acting, it would be as sure. Through all of this the third adult devil continued to lie motionless, only its wicked eyes giving any indication that it was alive. Dalgard watched it impatiently. Unless it would move, allow him a chance to aim at the soft underparts, there was little chance of killing it.
