Kit ran as fast as his legs would go beside the dogs, holding the
lines. But the dogs had four legs apiece, and Kit had only two;
so you see he couldn't keep up very well.

Kat began to scream the moment that Peter and Paul began to run.
The dogs thought that something that made a dreadful noise was
after them, and they ran faster than ever. You see, Grandfather
Winkle never in the world screamed like that, and Peter and Paul
didn't know what to make of it. So they ran and ran and ran.

Kat held on the best she could, but she bounced up ever so far in
the air every time the cart struck a bump in the street. So did
the milk cans; and when they came down again, the milk splashed
out.

Kat didn't always come down in the same spot. All the spots were
hard, so it didn't really matter much which one she struck as she
came down.

But Kat didn't think about that; she just screamed. And Peter and
Paul ran and ran, and Kit ran and ran, until he couldn't run any
more; he just sat down hard on the pavement and slid along. But
he didn't let go of the lines!

When Kit sat down, it jerked the dogs so hard that they stopped
suddenly. But Kat didn't stop; she went right on. She flew out
over the front of the cart and landed on the ground, among all of
Peter and Paul's legs! Then she stopped going, but she didn't
stop screaming.
