another race, that was not real—or else far, far removed from where he now sat.

Yet there had been no dividing line between those two worlds. One moment he had been in the desert place, returning from a successful foray against the Mexicans. Mexicans! Travis caught at that identification, tried to use it as a thread to draw closer to the beginning of his mystery.

Mexicans.... And he was an Apache, one of the Eagle people, one who rode with Cochise. No!

Sweat again beaded his face where the water had cooled it. He was not of that past. He was Travis Fox, of the very late twentieth century, not a nomad of the middle nineteenth! He was of Team A of the project!

The Arizona desert and then this! From one to the other in an instant. He looked about him in rising fear. Wait! He had been in the dark when he got out of the desert, lying in a box. Getting out, he had crawled down a passage to reach moonlight, strange moonlight.

A box in which he had lain, a passage with smooth metallic walls, and an alien world at the end of it.

The coyote's ears twitched, her head came up, she was staring at the man's drawn face, at his eyes with their core of fear. She whined.

Travis caught up the two pieces of horn, thrust them into his sash belt, and got to his feet. Nalik'ideyu sat up, her head cocked a little to one side. As the man turned to seek his own back trail she padded along in his wake and whined for Naginlta. But Travis was more intent now on what he must prove to himself than he was on the actions of the two animals.

It was a wandering trail, and now he did not question his skill in being able to follow it so unerringly. The sun was hot. Winged things buzzed from the bushes, small scuttling things fled from him through the tall grass. Once Naginlta growled a warning which led them all to a detour, and Travis might not have picked up the proper trace again had not the coyote scout led him to it.

"Who are you?" he asked once, and then guessed it would have better been said, "What are you?" These were not animals, or rather they were more than the animals he had always known. And one part of him, the part which remembered the desert rancherias where Cochise had ruled, said they were spirits. Yet that other part of him.... Travis shook his head, accepting them now for what they were—welcome company in an alien place.

The day wore on close to sunset, and still Travis followed that wandering trail. The need which drove him kept him going through the rough country of hills and ravines. Now the mist lifted above towering walls of mountains very near him, yet not the mountains of his memory. These were dull brown, with a forbidding look, like sun-dried skulls baring teeth in warning against all comers.

With great difficulty, Travis topped a rise. Ahead against the skyline stood both coyotes. And, as the man joined them, first one and then the other flung back its head and sounded the sobbing, shattering cry which had been a part of that other life.

The Apache looked down. His puzzle was answered in part. The wreckage crumpled on the mountain side was identifiable—a spaceship! Cold fear gripped him and his own head went back; from between his tight lips came a cry as desolate and despairing as the one the animals had voiced.
