‘Gentlemen,’ went on the Sorcerer, ‘here are the children I have spoken about. They are young and fairly adaptable. Study them. Our working mechanicos can be improved. For instance, these children feel pain. It is a wise provision of nature. If our mechanicos felt pain they would do themselves less injury, and there would be less work for the repair shop. A repair shop is a sign of inefficiency. ‘Gentlemen, I repeat that much may be learned from this boy and girl.’ ‘If only,’ breathed an Executive softly, ‘mechanicos could create other mechanicos as the animals give birth to other animals, it would save a great deal of raw material.’ ‘Some day, perhaps, we may manage that,’ answered the Sorcerer casually. Then he turned to the children. ‘Come on, Raphael and Cassandra, I want to show you the rest of the city before dark.’ They all bowed politely to one another. Mechanus, Raphael, and Cassandra left _Big Business Building_ and took a taxicab for the outskirts of the city. While they were being jerked along at a tremendous speed, Raphael asked the Sorcerer if they made any child mechanicos. ‘Goodness, no,’ answered Mechanus. ‘Childhood is nothing but waste. A child mechanico could not do the work of a man, and he would drink almost as much oil.’ ‘Don’t mechanicos have any fun at all?’ ‘A mechanico,’ said Mechanus, ‘doesn’t know what fun is.’ ‘I’m glad I’m not a mechanico,’ said Cassandra. ‘Are you, my dear?’ said Mechanus and gave her a queer look. The taxicab stopped with a jerk outside of a huge factory of concrete and glass on the side of which was painted in gold letters, _Mechanico Mammoth Machine Works_. The Sorcerer opened a side door and Raphael and Cassandra followed him inside. As the door shut behind them the roar of machinery sounded like an angry waterfall. ‘Wait a moment here,’ said the Sorcerer, ‘while I look for the Superintendent. You may go through that door there, if you want to.’ And he pointed to a steel door on which was painted, _For Employees Only_. Raphael and Cassandra went and peeked through. As they opened the door the noise of revolving machinery became louder, almost deafening them. Inside at a work bench stood two mechanicos adjusting artificial arms and hands. ‘If you don’t produce better goods, twenty thousand fifty-one, the Master will take you apart,’ one was saying to the other. ‘The last lot were a little stiff at the elbow.’ Raphael could not imagine what they were talking about. ‘Well, it isn’t my fault, two thousand fifty-six. The Master ordered clerks and I gave him clerks. Then what do you suppose he did? Slapped those arms right onto workers. Of course, they couldn’t stand the strain. They weren’t built for it.’ ‘Well, you want to watch out or you will land in the repair shop.’ The men continued passing metal arms onto a moving band that ran slowly by. Raphael suddenly realized that they were making parts to mechanical men. The men were made and put together like automobiles.
