Russ and Laddie looked at one another in surprise. Neither of them was near Mun Bun, and yet they could see the little fellow standing close to one of the spinning wheels, and his golden hair stuck straight out behind him, just as if an unseen hand had hold of it and was pulling it hard.

"Oh, stop! Stop! You hurt!" sobbed Mun Bun. "Let go my hair!"

But who had hold of it?

CHAPTER XIV

COASTING FUN

Russ and Laddie said, afterward, that they were much frightened at what happened. They were really more frightened than was Mun Bun, for he was not so much frightened as he was hurt. He thought some one had crept up behind him and was pulling his hair, as often happened when some of the six little Bunkers were not as good as they should be.

"Let go my hair! Stop pulling!" cried Mun Bun.

"We're not touching you," said Laddie.

"Is any one there?" asked Russ, looking to see if any one stood back of his brother.
