Bunny found that he could guide his dog from one side to the other by pulling on either the right or left rein.  And Splash did not seem to mind pulling the wagon with Bunny in it.  He went around the yard very nicely.

“Oh, give me a ride, Bunny!” begged Sue, who came in just then from having been down to Sadie West’s house, having a dolls’ party.

“Yes, I’ll give you a ride, Sue,” Bunny said.  “Get in!  Whoa, Splash!” he called.  The dog did not “whoa” very well, but finally he stopped, and Sue got in the wagon, sitting behind Bunny.

They drove around the yard for a while, and then Sue said: 

“Oh, Bunny, let’s go out on the sidewalk, where it’s nice and smooth.  It will be easier for Splash to pull us then.”  Bunny thought this would be fun, so he guided the dog out through the gate.  The wagon did go more smoothly on the sidewalk, and Splash trotted a little faster.

“Oh, this is fun!” cried Bunny.

“I like it!” laughed Sue, who had her arms around Bunny’s waist, so she would not fall out backwards.

They had not gone very far before Sue cried: 

“Oh, Bunny!  Look!  There’s that yellow dog—­the one that had the tin can tied to his tail—­the one that upset our lemonade stand!”

“So it is!” said Bunny.

And, just at that moment, Splash also saw the yellow dog.

With a bark and a wag of his tail, Splash gave a big jump, nearly throwing Bunny and Sue out of the wagon.  Then the big dog began to run after the little one.

“Whoa!  Whoa!” cried Bunny, pulling on the reins.  But Splash would not stop.  Faster and faster he ran.  He only wanted to see his little yellow dog friend again, and rub noses with him.  But I guess the yellow dog was frightened when he saw the express wagon, with the two children in it, following after Splash.

Maybe the yellow dog thought the wagon was tied to the tail of Splash, as the tin can had once been to his own.  And maybe the little yellow dog thought some one would now tie an express wagon to his tail.  At any rate he ran on faster and faster, And Splash, who just wanted to speak to him, in dog language, ran on faster too.

“Bumpity-bump-bump!” went the wagon with Bunny and Sue in it.

“Whoa!  Whoa!” called Bunny.

But Splash would not stop.  He was running away, but he did not mean to.  He just wanted to catch up to the little yellow dog who was running on ahead.

CHAPTER XXI

HOW SUE FOUND THE EGGS

“Oh, Bunny!  Can’t you make him stop?” cried Sue, as she clung with her arms about her brother’s waist, while the wagon swayed from side to side.

“I—­I’m trying to,” answered Bunny, pulling as hard as he could on the reins.  “But he won’t stop.  Whoa!  Whoa!” and Bunny called as loudly as he could.

Down the street Splash kept running.  He was getting nearer to the little yellow dog, for this dog had only short legs, and Splash had long ones, and, of course, anyone with long legs can run faster than anyone with short legs.
