"It is queer," said Grandpa Martin, when he came up and heard what had taken place. "I wonder if any of those—"

Then he stopped talking and looked at the children's mother in a queer way. She nodded her head, glanced down at the Curlytops and Hal, and put her finger across her lips as your teacher does in school when she wants someone to stop whispering.

Hal saw what Mrs. Martin did, but neither Jan nor Ted noticed, for they were running around looking for any of the blue stones that might have been scattered from Trouble's playhouse.

"Never mind," said Mother Martin. "I'll find you something else to play with, Trouble. You shall have a nice ride with Nicknack. You'll take him, won't you, Jan and Ted?"

"Yes," they answered.

"I want my p'ayhouse!" sobbed Baby William, and for a time he made a fuss about his missing blue stones.

'"I guess I know what happened to them," said Hal in a whisper to Jan and Ted when their mother had taken Trouble into the tent to find something with which to amuse him.

"What?" asked Ted in a whisper.

"The tramps!" exclaimed Hal, looking over his shoulder to make sure no one but Ms two little friends heard him. "That's what your grandfather was going to say the time he stopped so quick. Your mother didn't want him to speak of them. But I'm sure the tramps took the blue stones from Trouble's castle."

"What would they do with 'em?" Ted demanded.
