Bunny thought for a moment.

"Maybe I can make it better than that," he said. "I could fasten the bell up in the tree back of your tent-house, and then tie a string to it—to the bell, I mean. I can let the string hang down outside here, and when I come I can yank on the string, and that will jingle the bell."

"Oh, let's do it!" cried Sue.

So Bunny got the milkman's bell, and fastened it to a low limb in a tree back of the tent-house where Sue pretended she was living.

Then Bunny tied a string to the bell handle and ran the string out in front, letting it hang loose, so that a pull on it would set the bell to swaying and jingling. To make it easier to take hold of the string, Bunny fastened to it a piece of wood. Then he and Sue began the playing-house game.

They had lots of fun at it. The bell rang just like a "truly-really" one, as Sue said, and when Bunny jingled it, and came in to sit down on a box (which was a chair), Sue would give him cookies.

They were sitting like this, wondering what next to play when, all at once, there came a loud jingle on the bell that was hung in a tree back of the tent.

"Are you doing that?" asked Sue of her brother.

"No!" he answered. "How could I? The bell string is outside and I'm in here."

"I thought maybe you had hold of the string in here," went on Sue. Then the bell was rung again.
