“Now, never you mind,” said the papa to the boy. “You'll be putting up your lip before I'm through. Well, and then she used to caution the little Pony Engine against getting in the way of the big locomotives, and told it to keep close round after her, and try to do all it could to learn about shifting empty cars. You see, she knew how ambitious the little Pony Engine was, and how it wasn't contented a bit just to grow up in the pony-engine business, and be tied down to the depot all its days.

“Couldn't it?” asked the little girl, gently.
“No; they're kind of mooley.”
The little girl asked the papa, “What makes Pony Engines mooley?” for she did not choose to be told by her brother; he was only two years older than she was, anyway.
“Well; it's pretty hard to say. You see, when a locomotive is first hatched—”
“Oh, are they hatched, papa?” asked the boy.

“What makes the spout ever drop off?”
“Oh, sometimes the pip, or the gapes—”
