gratefully chew their cuds under red, green and purple suns. You accept us as something sometimes helpful. You walk into our spaceships as you walked up to our fires. You use us. But when we're gone, you won't pine on our graves or starve in the pen. You'll manage, or try to." The cat mewed. He tossed it a bit of meat, which it caught in its teeth, shifting about cleverly on the two good hind legs. As he watched it daintily nibble (though scrawny with famine), he suddenly saw Kenneth's face, just as he had last seen it on Alpha Centauri Duo. It seemed very real, projected against the maroon darkness towards the other end of the cellar. The full tolerant lips lined at the corners, the veiledly appraising eyes, the space-sallow skin were all exactly as they had been when they roomed together at the Sign of the Burnt-Out Jet. But there was a richness and a zest about the face that he had missed before. He did not try to move toward the illusion, though he wanted to. He only looked. Then there came the sound of boots on the floor above, and the cat bounded away, humping its hind quarters quite like a tripedal, and the vision quickly faded. For a long time he sat staring at the spot where it had been, feeling a strangely poignant unhappiness, as if the only worthwhile being in the world had died. Then he started to eat his food with the vague curiosity of a two-year-old, sometimes pausing with the spoon half-way to his mouth.

Three men came out of the place of underground concealment to the left, joking together in hushed, hollow voices. One whom he knew well (a stocky soldier with big eyes and smirking lips and reddish stubble on his chin) greeted him with a friendly jibe about easy jobs. Then they wormed their way up and over, and started to crawl toward where enemy scouts (six legs or eight?) were supposed to lie. He lost sight of them very quickly. He held his weapon ready, watching for the sight of the enemy. Why did he hate the soldiers of the enemy so little? No more than a Martian hunting sand-dragons hates sand-dragons. His relationship with them was limited, almost abstract. How could he hate something so different from himself in form? He could only marvel that it too had intelligence. No, the enemy were merely dangerous targets. Once he had seen one of them escape death, and it had made him feel happy; he
