oked as if
it had been there a long time.

"Kat, you must wear this," she said. "It was your mother's when she was
a little girl."

Now, this apron was all faded, and it had patches on it of different
kinds of cloth. Kat looked at her best dress. Then she looked at the
apron. Then she thought about the milk cart. She wondered if she wanted
to go in the milk cart badly enough to wear that apron over her Sunday
dress! She stuck her finger in her mouth and looked sidewise at
Grandmother Winkle.

Grandmother didn't say a word. She just looked firm and held up the
apron.

Very soon Kat came slowly--very slowly--and Grandmother buttoned the
apron up behind, and that was the end of that.

The Twins could hardly eat any breakfast, they were in such a hurry to
go. As soon as they had taken the last spoonful, and Grandfather Winkle
had finished his coffee, they ran out into the place where the dogs
were kept, to help Grandfather harness them.

There were two black and white dogs. Their names were Peter and Paul.

The wagon was small, just the right size for the dogs; and it was
painted blue. The bright brass cans full of milk were already in; and
there was a little seat for Kat to sit on.

When the last strap was fastened, Grandfather lifted Kat up and set her
on the seat. She held on with both hands.

Then Grandfather gave the lines to Kit, and a little stick for a whip,
and told him to walk slowly along beside the dogs. He told him to be
sure not to let go of the lines.

Grandfather walked behind, carrying some milk cans.

Grandmother stood in the door to see them off; and, as they started
away, Kat took one hand off the cart long enough to wave it to her.
Then she held on again; for the bricks in the pavement made the cart
joggle a good deal.

"We must go first to Vrouw de Vet," Grandfather called out. "She takes
one quart of milk. Go slowly."

At first Kit went slowly. But pretty soon there was a great rattling
behind him; and Hans Hite, a boy he knew, drove right past him with his
dog cart! He drove fast; and, as he passed Kit, he stuck out his tongue
and called out,

"Milk for sale! Milk for sale!
A milk cart drawn by a pair of snails!"

Kit forgot all about going slowly.

"Get up!" he said to the dogs, and he touched them with his long stick.

Peter and Paul "got up." They jumped forward and began to run!

Kit ran as fast as his legs would go beside the dogs, holding the
lines. But the dog
