"Do you suppose you could have got up in the night, walked in your sleep, and hidden the train somewhere else yourself?" asked Uncle Tad.

"Well, about a year ago that might have happened," said Mother Brown. "But Bunny is cured of his sleep-walking habits now. He hasn't gotten up for several months, unless, as happened the other night when the cow poked her head in the tent, he woke up and cried out."

"But no cow came into the tent last night, Mother," said Bunny. "Anyhow a cow wouldn't like to eat a train of cars."

"A cow eat a train of cars!" cried Daddy Brown, coming into the tent just in time to hear what Bunny said. "Say, is that a riddle?"

"No. But it's a riddle to guess who or what took Bunny's train of cars," said Mrs. Brown. "He says he left them here, in front of the stove to dry out the water as you told him to, but they are gone now."

"That's queer," said Mr. Brown, looking about. "Is Bunny's train the only thing that is missing?"

"It seems to be, as far as we can tell by a hasty look around. But we'll have to see," said Mother Brown.

Uncle Tad, Mr. Brown and Bunny and Sue looked carefully about the tent while Mrs. Brown got breakfast. They saw several footprints, for the children, as well as the grown folks, had been about the tents all day, and Eagle Feather, the Indian, had also been there.

"Who knew that you had a train of cars?" asked Mr. Brown of his son when a long search had failed to find the toy.

"Well, I told the boy who brings the milk, the butter and egg man, and I guess that's all," said Bunny.
