He went hungry that day, but in the evening he slept much more comfortably at the foot of an old tree on a vacant lot. Far above he could see the star from which he had come. He stared at it impersonally for a short time, wondering whether he would see his own planet again. Then he fell into a half-sleep, one that rested him, though still leaving his senses partly alert. He was becoming more accustomed to the rather short day-and-night rhythm of the planet, and he awoke at the first faint signs of daylight before anyone had noticed him. That day he encountered groups of men congregated about dingy little buildings on a dingy street. He found that they were seeking employment, and knowing that the best way to learn about a strange race was to study the manner in which the people worked, he joined one of the groups. But there was not a single occupation with regard to which he could claim experience, and he was hired finally to do heavy, but unskilled labor, at eighty cents an hour. The work was more difficult for him than for the others. He looked like them, but they had muscles which he simply did not possess. He was so clumsy at lifting rocks that another man, with whom he was working, said finally in exasperation, “Didn’t you ever lift anything before? Look, pal, do it like this. Bend at the knees, see? That’s it, like this--no, you’re doing it all wrong!” * * * * * It was a nuisance, it might even be dangerous, to be stared at so closely. The fact was that his knees simply would not bend as human knees did. They were jointed in quite another fashion, and no surface similarities could conceal the fact that in action there was all the difference of two worlds between them. He said, “Sorry. I--injured.” “Oh, can’t bend them, huh? This is no job for you, pal.” “Am stranger. Know not--what else.” “Yeah, it’s tough.” He returned to his work again, this time warmed by the other’s sympathy, and less uneasy about being observed. And as he worked, he thought sardonically of what they would think on his home planet if they knew. He was sure that his enemies would have roared with laughter. Here was Kayin, the one they had feared for his brilliant mind, for his knowledge of science, for his practical skill. They had outwitted him--with the odds on their side, it was true--driven him a hunted creature past strange stars, and forced him to come to ground again in the guise of one of the meanest of a mean and unintelligent race. And even in the humble position to which he had been reduced, he could not hold up his end of the work. He clenched his jaws grimly at the thought, and the very motion made him realize that in no way was he like the others, that even so simple a matter as the number and shape of his teeth might give him away. Unintelligent as they were, once they took the trouble to look with some care, they would know a creature who was not one of them.
