On the second day of work he did arouse suspicion, but at first not from the other workers. The creature that bared its teeth and barked at him was a dog. For a time Kayin found the animal’s attention embarrassing. He threw a stone at the beast, but it ran only a short distance, and stopped to bark again. He had an idea of what the trouble was. That day he had replaced his worn trousers by a new and baggy pair of overalls, not yet saturated with the scent of human beings, and the dog had noticed his own faint but strange odor. Now it was making a nuisance of itself, and drawing everyone’s attention to him. “That mutt don’t like you, Mac,” said a foreman who passed by. “Funny about dogs, the way they bark at some people,” someone laughed. Kayin threw another stone, but the beast dodged and continued to bark. His audience was growing now, and Kayin’s skin began to twitch nervously, in a way that itself might have drawn an audience if they had been in a mood to notice such details of behavior. “I patted cat this morning,” he said apologetically. “Crazy dog smells cat.” He would have them all staring at him if this went on much longer, and he knew that he had to act quickly. Looking around him, he spied a compressed air hose lying on the ground. He picked it up, turned on the air, and directed the nozzle at the dog. The blast knocked the animal head over heels, and sent him howling on his way. Everyone laughed, and Kayin turned back to his work in relief. But from now on he knew that he must wear no new clothes. As the work progressed, his attention turned from the immediate tasks at hand, and he began to wonder what its purpose was. There seemed to be hundreds of men, all engaged in menial tasks, all part of some greater overall plan. He began to wonder, too, if people who could make such plans could be so unintelligent as he had first assumed. Or was it simply that their intelligence had not developed, that they lacked the background of science to make the most of their minds, to use the resources their planet possessed? A rough voice, almost the twin of that first rough voice of two days before, growled, “Hey, you, wake up and get movin’. Whaddya think you’re gettin’ paid for?” He swung his pick without looking up. The foreman had no idea that the tall foreigner he knew as Kane was staring at him curiously with tiny camouflaged eyes that quite literally grew in the back of the strangely shaped head, trying to understand what made the human being tick.
