"Now do you understand?" asked the Imp, anxiously.
"I think I do," replied Jimmieboy. "A battery is nothing but a lot of big glass jars in which 'lectricity is made, just as pie is made in a tin plate and custard is made in cups."
"Exactly," said the Imp. "But, of course, electricity is a great deal more useful than pie or custard. The best custard in the world wouldn't move a horse-car, and I don't believe anybody ever saw a pie that could light up a room the way this is. It's a pretty wonderful thing, electricity is, but not particularly good eating, and sometimes I don't think it's as good for cooking as the good old-fashioned fire. I've had pie that was too hot, and I've had pie that was too electric, and between the two I think the too-hot pie was the pleasanter, though really nothing can make pie positively unpleasant."
"So I have heard," said Jimmieboy, with an approving nod. "I haven't had any sperience with pie, you know. That and red pepper are two things I am not allowed to eat at dinner."
"You wouldn't like to taste some of my electric custard, would you?" asked the Imp, his sympathies aroused by Jimmieboy's statement that as yet he and pie were strangers.
"Indeed I would!" cried Jimmieboy, with a gleeful smile. "I'd like it more than anything else!"
"Very well," said the Imp, turning to the button-board, and scratching his head as if perplexed for a moment. "Let's see," he added. "What is custard made of?"
"Custard?" said Jimmieboy, who thought there never could be any question on that point. "It's made of custard. I know, because I eat it all up when I get it, and there's nothing but custard in it from beginning to end."
The Imp smiled. He knew better than that. "You are right partially," he said. "But there aren't custard-mines or custard-trees or custard-wells in the world, so it has to be made of something. I guess I'll ask my cookery-book."
