"To find Mun Bun."

"But he isn't with Mother!"

"I bet—No, I don't mean that word," said Russ. "I mean I think he is with Mother, only she doesn't know it."

"Why, Russ Bunker, that sounds awfully silly!"

But she followed after him in much haste. They came running to the two staterooms which Daddy Bunker had engaged. Mother and the other children were the center of a group of sympathetic people in the corridor.

"Oh! did you find him?" Rose cried.

"Of course not," said Vi. "Where should we find him?"

"Here," announced Russ, pushing through the crowd.

"Of course he isn't here, Russ," said Vi. "Can't you count us? Mun Bun is not here."

"Well, let me see," said the boy, and he pushed into the bigger stateroom where his mother had been working when Mun Bun disappeared. Then he opened the door between that room and the other room. It was all quiet in there. He glanced into the two berths. There was nobody in either of them.
