"I'll tell you what we can do," said Uncle Fred.
"What?" asked Daddy Bunker.
"Since we know Mun Bun is safe in this car, as the porter says he couldn't get off, we can wait until morning. He surely is in some berth, and is, very likely, sleeping soundly. Why not let him alone until morning?" answered Uncle Fred.
"Oh, no! Never!" cried Mrs. Bunker. "I must have him found, even if we have to wake up everybody in the train. I must find Mun Bun!"
Once more the porter hesitated.
"Well, if it has to be done, it has to be," he said. "I'll start at one end, an' you two gen'mens can start at the other end of the car, and maybe we won't have to wake up quite everybody."
Just as they were going to start to make this search a voice from behind the colored porter called.
"Are you looking for a lost boy?" inquired a man who wore an old-fashioned night-cap on his head, which he stuck out from between the green curtains of his berth.
"Yes!" eagerly exclaimed Mr. Bunker.
"Have you one there?" asked Uncle Fred, turning to look at the man.
