"Did you know he was going to do it?" asked Rose, as she looked at the snow man carefully.

"No, I didn't know anything about it," said Russ. "I was walking along with you all, just now, and, all of a sudden, I saw the hat come off. First I thought the wind blew it, and then, when I saw it wave at me, and go back on his head, I knew somebody did it—or—or maybe he did himself."

"But he couldn't, 'cause he's a snow man," insisted Laddie. "And I helped make him and you didn't put any phonograph or any machinery in him. You didn't, did you, Russ?"

"No, not a thing. He's just a snow man."

"Then he couldn't do it!" declared Rose. "But maybe it was Mr. Ghost! No, it couldn't be that 'cause he only makes a noise, and, anyhow, there isn't any such thing. But what is it?"

"Look! He's doing it again!" cried Vi.

Surely enough, the snow man once more took off his tall silk hat, and waved it toward the children. Then it went back on his head again, but this time it was not quite straight. It was tilted to one side, and gave him a very odd look.

"Ho! Ho! Isn't he funny!" laughed Mun Bun. "I like that snow man. I'm going to see what makes him take off his hat!"

"No, don't!" cried Rose, catching hold of her little brother's arm as he was about to run toward Mr. White.

"Why not?" Mun Bun wanted to know.
