and the wind increased, smashing at the shelters with a violence they had not been built to withstand. The prowler skin lashings held but the canvas and blankets were ripped into streamers that cracked like rifle shots in the wind before they were torn completely loose and flung into the night. One by one the guard fires went out and the rain continued, growing colder and driven in almost horizontal sheets by the wind. The women and children huddled in chilled misery in what meager protection the torn shelters still gave and there was nothing that could be done to help them. The rain turned to snow at midnight, a howling blizzard through which Prentiss's light could penetrate but a few feet as he made his rounds. He walked with slogging weariness, forcing himself on. He was no longer young—he was fifty—and he had had little rest. He had known, of course, that successful leadership would involve more sacrifice on his part than on the part of those he led. He could have shunned responsibility and his personal welfare would have benefited. He had lived on alien worlds almost half his life; with a rifle and a knife he could have lived, until Ragnarok finally killed him, with much less effort than that required of him as p. 23 leader.

What he knew of survival on hostile worlds might help the others to survive. p. 23 So he had assumed command, tolerating no objections and disregarding the fact that he would be shortening his already short time to live on Ragnarok. It was, he supposed, some old instinct that forbade the individual to stand aside and let the group die. The snow stopped an hour later and the wind died to a frigid moaning. The clouds thinned, broke apart, and the giant star looked down upon the land with its cold, blue light. The prowlers came then. They feinted against the east and west guard lines, then hit the south line in massed, ferocious attack.

As they did so the call, prearranged by him in case of such an event, went up the guard lines: "Emergency guards, east and west—close in!" In the camp, above the triumphant, demoniac yammering of the prowlers, came the screams of women, the thinner cries of children, and the
