"Dear me, I hadn't the least idea of it," John answered gravely. "May I ask what an Incubator Baby is?"
The child squatted down in the sand, hugged its chubby knees, and uttered peal after peal of joyous laughter.
"How funny!" it gurgled; "how funny that you don't know what the Incubator Baby is! Really, you must be fresh-baked!"
"I am," said John, feeling rather ashamed to acknowledge the fact, but resolving to be truthful.
"Then, of course, you are very ignorant," remarked the Fresh-Air Fiend, rubbing his big head complacently.
"Oh, as for that," said John, "I acquired, in course of manufacture, a vast deal of ancient learning, which I got from an Arabian Elixir with which the baker mixed me. I am well posted in all events down to the last century, but I cannot recall any knowledge of an Incubator Baby."
"No, they're a recent invention," declared the big-headed man, patting tenderly the child's golden curls. "Were you, by any chance, at the Pan-American Exposition? Or the Louisiana Purchase Exposition?"
