te 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?

CHAPTER XIV

THE WHISTLING WAGON

Mun Bun smiled happily. This was more fun than he had ever expected to
have at Aunt Jo's house. In fact, what little thinking he did about it
was to the effect that he could have had a lot more fun by staying at
Grandma Bell's.

Up he sat on the seat of the junkman's wagon, holding the reins as he
had helped Russ or Laddie hold the reins on the big dog Alexis, who
pulled the six little Bunkers in the express wagon.

"This is fun!" said Mun Bun.

The horse slowly walked along. Junkmen's horses hardly ever run. There
are several reasons for this.

In the first place, a junkman's horse goes slowly because the junkman is
never in a hurry. He wants to look at the houses on each side of the
street to see if any one is going to call him in to sell him paper,
rags, old bottles, rubber boots or broken stoves.

So, of course, a junkman wants his horse to go slowly, for then he has a
chance to look at the houses on each side of the street. For nowadays
the junkmen, in the cities, at least, are not allowed to ring bells and
shout loudly or make much noise. They used to do that, but they can't
any more.

Another reason why a junkman's horse walks slowly is that the poor horse
is nearly always old and thin and hungry.

And I suppose it's a good thing this junkman'
