is heels,
and going faster and faster all the while.

"He's running hard; isn't he, Bunny?" asked Sue.

"Yes, he--he's going fast--very fast!" panted Bunny, in a sort of jerky
way, for the cart rattled over some bumps just then, and if Bunny had
not been careful how he spoke he might have bitten his tongue between
his teeth.

"Don't--don't you li--like it--Wop--Wopsie?" asked Sue, speaking in the
same jerky way as had her brother.

Wopsie did not open her mouth. She just held tightly to the edge of the
pony cart, and shook her head from side to side. That meant she did not
like it. Sue and Bunny wondered why.

True, they were going a bit fast, but then they had often ridden almost
as fast when Splash, their big dog, drew them in the express cart. And
this was much nicer than an express cart, though of course Bunny and Sue
liked Splash better than this pony. But if they had owned the pony they
would have liked him very much, also, I think.

Now the pony swung around a corner of the drive, and he went so fast,
and turned so quickly, that the cart was nearly upset.

Sue held tightly to the side of her seat, and called to her brother:

"Oh, Bunny! Don't make him go so fast! You'll spill me and Wopsie out!"

"I didn't make him go fast," Bunny answered. "I--I guess he's in a hurry
to get away from that dog."

"Make the dog go 'way," pleaded Sue.

Bunny looked back at the barking dog, who was still running after the
pony cart.

"Go on away!" Bunny cried. "Let us alone--go on away and find a bone to
eat!"

But the dog either did not understand what Bunny said, or he would
rather race after the pony cart than get himself a bone. At any rate he
still kept running along, barking and growling, and the pony kept
running.

The boy who had started out with the children, first walking along
beside the pony, was now far behind. He was a small boy, with very short
legs, and, as the pony's legs were quite long, of course the boy could
not run fast enough to keep up. So he was now far behind, but he kept
calling:

"Stop that pony! Oh, please someone stop that pony!"

Bunny and Sue heard the boy calling. So did Wopsie, but the colored girl
said nothing. She just sat there, holding to the side of the seat and
looking at Bunny and Sue.

"I wonder what that boy's hollering that way for?" asked Sue, as the
pony swung around another corner, almost upsetting the cart again.

"I don't know," said Bunny. "Maybe he likes to h
