“Oh, yes, I know,” said Laddie.

They found some string and made a belt of it, putting it around each of the two big spinning wheels.  Then, by turning one, the other, at some distance away, could be made to go around.

“This is just like an airship!” cried Laddie.  “We’ll make believe this is the engine, and we’ll go up in it.”

This the boys did, even pretending to take Mun Bun up on one trip.  Then they played other games with the spinning wheels, making believe they worked in a big factory, and things like that.

By this time Laddie and Russ had forgotten about Mun Bun, and the little fellow had wandered off by himself to the place in the attic where the strings of sleigh bells hung.  He had fun jingling these.  Then Russ and Laddie found something else with which to play.  These were the candle-moulds.  Leaving the spinning wheels, with a number of strings and cords still fast to them, the two older boys began to make believe they were soldiers with the candle-moulds for guns.

“I’ll be a soldier and you can be an Indian,” said Russ to Laddie.  “I must live in a log cabin, and you must come in the night and try to get me, and I wake up and yell ‘Bang!  Bang!’ That means you’re shot.”

“All right, and then I must shoot you, after a while.”

“Sure, we’ll play that way.”

So they did, and had fun.  They aimed at one another with the candlestick moulds and shouted so many “bangs!” that the attic echoed with the noise.

Then, suddenly, as they stopped a moment for breath, they heard the voice of Mun Bun crying: 

“Oh, stop pulling my hair!  Stop pulling my hair!  Oh, it hurts!”

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.

But he could look right through the spokes of the spinning wheel, near which Mun Bun was standing, and see no one except his little brother.  And the bobbed, golden hair of Mun Bun still stuck straight out behind him, as stiff as if the wind were blowing it, or as if some one had hold of it.
