Sssuri stood at the grille, one hand on its stone divisions. His surprise equaled Dalgard's. It was not in his experience either that the untamed snake-devils, regarded by merman and human alike as so dangerous as to be killed on sight, could be banded—as if they were personal pets!

For a moment or two a wild idea crossed Dalgard's mind. How long was the natural life span of a snake-devil? Until the coming of the colonists they had been the undisputed rulers of the deserted continent, stupid as they were, simply because of their strength and ferocity. A twelve-foot, scale-armored monster, that could tear apart a duocorn with ease, might not be successfully vanquished by any of the fauna of Astra. And since the monsters did not venture into the sea, contact between them and the mermen had been limited to casual encounters at rare intervals. So, how long did a snake-devil live? Were these creatures sprawled here in sleep ones that had known the domination of Those Others—though the fall of the master race of Astra must have occurred generations, hundreds of years in the past?

"No," Sssuri's denial cut through that. "The smaller one is not yet full-grown. It lacks the second neck ring. Yet it is banded."

The merman was right. That unpleasant wattle of armored flesh which necklaced the serpent throat of the devil Dalgard had picked as his target was thin, not the thick roll of fat such as distinguished its two companions. It was not fully adult, yet the band was plain to see on the foreleg now stretched to its full length as the sun bored down to supply the heavy heat the snake-devils relished next to food.

"Then—" Dalgard did not like to think of what might be the answer to that "then."

Sssuri shrugged. "It is plain that these are not wild roamers. They are here for a purpose. And that purpose—" Suddenly his arm shot out so that his fingers protruded through the slits in the stone grille. "See?"

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.
