Sometimes, even in the fashionable Back Bay section of Boston, rag peddlers came to buy odds and ends from the homes of the people. The chauffeurs or the furnace men usually attended to the selling of this, being allowed to keep whatever money they got for themselves.

One of the wagons, with bags and all sorts of things in it, stopped, one day, in front of Aunt Jo's house. The ragman knew William, who often sold him old newspapers or junk, and this time he had quite a few things to sell.

"Rags! Rags! Bottles and rags!" cried the junkman as he went back to the garage with a bag over his shoulder.

As it happened, Mun Bun was out, watching William pump air into a new tire, and when the chauffeur went into the cellar with the junkman to get the papers, Mun Bun wandered out in front to where the junkman's horse and wagon was standing.

"If I could get up into that wagon now," thought Mun Bun to himself, "I could have a better ride than with Alexis. I guess I will."

How he managed to climb up I don't know, but he did. The wagon was not very high, and there was a step near the front, and of course there were wheels. Somehow, Mun Bun scrambled up, and the horse, luckily for him, did not move while the boy was climbing. Right up on the seat got Mun Bun. He picked up the real reins, as he had seen Russ do with the make-believe ones on Alexis, and then Mun Bun called:

"Gid-dap!"

And, just as easily as you please, the horse started off as natural as anything, with Mun Bun driving. Down the street he slowly walked, much to the delight of Mun Bun.

But what would happen next?
