be called
Christopher and Katrina."

"Well, well, well!" said the large woman. "So you are! Now my name is
Vrouw Van der Kloot. Are you helping Father?"

"Yes," said the Twins. "We're going to help him sell things."

"Then you may sell me a cabbage and ten onions," said Vrouw Van der
Kloot.

Father Vedder's eyes twinkled, and he lit his pipe. Kit got a cabbage
for the Vrouw.

"You can get the ten onions," he said to Kat. You see, really Kit
couldn't count ten and be sure of it. So he asked Kat to do it.

Kat wasn't afraid. She took out a little pile of onions in a measure,
and said to Vrouw Van der Kloot,

"Is that ten?"

Then Vrouw Van der Kloot counted them with Kat, very carefully. There
were eleven, and so she gave back one. Then she gave Kat the money for
the onions, and Kit the money for the cabbage.

Father Vedder said, "Now Kit and Kat, by and by, when you get hungry
again, you can go over to Vrouw Van der Kloot's stall and buy something
from her. She keeps the sweetie shop."

"Oh! Oh!" cried Kit and Kat. "We're hungry yet! Can't we go now?"

"No, not now," said Father. "We must do some work first."

The Twins helped Father Vedder a long time. They learned to count ten
and to do several other things. Then their father gave them the money
for the cabbage and the ten onions they had sold to Vrouw Van der
Kloot, and said,

"You may walk around the market and look in all the stalls, and buy the
thing you like best that costs just two cents. Then come back here to
me."

Kit and Kat set forth on their travels, to see the world. They each
held the money tightly shut in one hand, and with the other hand they
held on to each other.

"The world is very large," said Kit and Kat.

They saw all sorts of strange things in the market. There were tables
piled high with flowers. There was a stall full of birds in cages,
singing away with all their might. One cage had five little birds in
it, sitting in a row.

"O Kit," cried Kat, "let's buy the birds!"

They asked the woman if the birds cost two cents, and she said,

"No, my angels; they cost fifty cents."

You see, now that the Twins could count ten, they knew they couldn't
get the birds for two cents when they cost fifty. So they went to the
next place.

There, there were chickens and ducks for sale. But the Twins had plenty
of those at home. There were stalls and stalls of vegetables just like
Father's, and there were booths where meat and fish an
