isn't here," said Uncle Fred. "I'd have felt him if he had come into
my berth. I'll get up and help you look."

Uncle Fred quickly slipped on a bath robe and stepped out into the aisle
of the car. Then he and Daddy Bunker and the porter stood there in the
dim light.

"Did you find him, Charles?" asked Mrs. Bunker in a low voice from her
berth.

"No, he wasn't with Fred."

"Oh, dear! What shall we do? You must find him!" she exclaimed, as she
poked her head out between the curtains.

"Well, ma'am, he couldn't fall off the train," said the porter, "'cause
we hasn't stopped for a long while, and the doors are tight closed at
each end of the car. He's here somewhere."

"He's in some other berth," put in Uncle Fred. "He must have walked in
his sleep, or something like that, and he's in with some one else he has
mistaken for his father or his mother, or one of his sisters or
brothers. We'll find him."

"But we can't wake up everybody in the car, to ask them if Mun Bun is
sleeping with them," said Mr. Bunker.

"We've just got to!" exclaimed his wife. "We must find Mun Bun!"

The porter looked disturbed. He did not very much like to awaken all the
sleeping passengers in the train, for some of them were sure to be
cross. They might blame him for their loss of sleep, and then he would
not get the usual tips of quarters or half dollars or dollars at the end
of the ride.

"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.

"Well,
