"You called me, sir," said Ace.

"Did I—what for? Do you know?"

"No, sir," said Ace.

"Excuse me," said Billy, "but I think it was to ask him if you were the Alchemist."

"That can't have been it, because I am the Alchemist. No doubt about that, is there, Ace?"

"No, sir," said Ace.

"Then don't interrupt me again with your foolish questions, Ace; you know it bothers me when I'm making up a sample eruption."

Ace bowed gravely, as if he were used to such things, and ran back to his work.

The Alchemist.
