“I—­I’m going to fall out!” Sue cried.  “I—­I’m slipping, Bunny!  I’m falling!”

“Hold on!  Hold on tight!” Bunny begged his sister, for the wagon was going very fast, and he knew if she fell out on the hard sidewalk she would get a hard bump.

Sue clasped her arms as tightly as she could about her brother’s waist, but her arms were short, and Bunny was rather fat, so it was not easy for her to hold fast.  Still she did her best.

Several persons on the other side of the street saw Bunny and Sue having a fast ride in the toy express wagon, drawn by the big dog, but they did not think the Brown children were in a runaway, which is just what they were.

“My! what fun Bunny Brown and his sister Sue are having!” said one man, as he watched the express wagon bump along.

“Yes, they always seem to be having good times,” replied a lady.

If they had only known it was a runaway, they might have run across the street and stopped Splash from going so fast.

On and on went the big dog.  He was almost up to the yellow one now, and the yellow dog began to yelp.  Perhaps he thought he was going to be caught and hurt.  Or maybe he feared Bunny or Sue would try to make him pull the big wagon, with them in it.

But of course they wouldn’t think of such a thing, and as for Splash, I have told you that all he wanted to do was to rub noses with his little yellow friend.

As the wagon rumbled past the house where lived Mr. Jed Winkler, the old sailor, who owned Wango, the monkey, came out to the front gate.  I mean Mr. Winkler came out, not Wango, for he had been tightly chained, after the fun he had had in Mrs. Redden’s candy shop.

“My!  What a fine ride you are having!” called Mr. Winkler.

“Oh!  It’s not a nice ride at all!” answered Sue.  “We’re being runned away with!  Please stop Splash!”

“Goodness me!” exclaimed Mr. Winkler.  “A runaway!  Well, I must stop it, of course!”

Out he ran from his yard to race after Splash, but there was no need for the old sailor to catch the big dog.  For, just then, the little yellow dog stumbled, and turned a somersault.  And before he could pick himself up, and run on again, Splash had caught up to him.

Now, this was all that Splash wanted to do—­catch up to the yellow dog and rub noses with him.  And as soon as Splash saw that the little dog had stopped, Splash stopped also.

But he stopped so suddenly that the wagon almost ran up on his back.  It turned around, and then it went over on one side, so that Bunny and Sue were spilled out.  But they fell on some soft grass, so they were not hurt a bit, though Sue’s dress was stained.

And as soon as the little yellow dog found that he was not going to be hurt, but that Splash was just going to be friends with him, why the two animals just sat down in the grass find rubbed noses and, I suppose, talked to each other in dog language, if there is any such thing.
