Knowing all the menaces which might lie in wait, even in the shallows of the sea, Dalgard drew his knife once more as he plowed through water—ready to rescue or at least to offer what aid he could.

THE DEAD GUARDIANS
The spacemen spent a cramped and almost sleepless night. Although in his training on Terra, on his trial trips to Mars and the harsh Lunar valleys, Raf had known weird surroundings and climates, inimical to his kind, he had always been able to rest almost by the exercise of his will. But now, curled in his roll, he was alert to every sound out of the moonless night, finding himself listening—for what he did not know.
Though there were sounds in plenty. The whistling call of some night bird, the distant lap, lap of water which he associated with the river curving through the long-deserted city, the rustle of grass as either the wind or some passing animal disturbed it.
"Not the best place in the world for a nap," Soriki observed out of the dark as Raf wriggled, trying to find a more comfortable position. "I'll be glad to see these bandaged boys on the ground waving good-bye as we head away from them—fast—"
"Those weren't animals they killed—back on that island." Raf brought out what was at the heart of his trouble.
"They wore fur instead of clothing." Soriki's reply was delivered in a colorless, even voice. "We have apes on Terra, but they are not men."
Raf stared up at the sky in which stars were sprinkled like carelessly flung dust motes. "What is a 'man'?" he returned, repeating the classical question which was a debating point in all the space training centers.
