puffs from his pipe without answering.

"We'll help you load the boat," said Kit.

"Yes," said Kat, "I can carry a cabbage."

"I can carry two," said Kit. "We'll both be good," said Kat.

"Very well," said Father, at last. "We'll see how you work! And to-morrow morning, if it's fair, I'll see! But you must go to bed early to-night, because you'll have to get up very early in the morning, if you go with me! Now you each take a cabbage and run along."

Father Vedder went back to his work.

Kit and Kat ran to the cabbage-pile. Kat took one, and Kit took two—just to show that he could.

"When Father says 'I'll see,' he always means 'yes,'" Kat said to Kit.

Perhaps it seems queer to you that they should go to market in a boat, but it didn't seem queer at all to the Twins.

Your see, in Holland there are a great many canals. They cross the fields like roadways of water, and that is what they really are. Little canals open into big ones, and big ones go clear to the sea.

It is very easy for farmers to load their vegetables for market right on a boat. They can pull the boat out into the big canal, and then away they go to sell their produce in the town.

The canals flow through the towns, too, and make water streets, where boats go up and down as carriages go here.

The Twins and their father worked like beavers, washing the vegetables and packing them in baskets, until their good old boat was filled with cabbages and onions and beets and carrots and all sorts of good things to eat.

By that time it was nearly dark, and they were all three very hungry; so they went home.

They found that Mother Vedder had made buttermilk porridge for supper. The Twins loved buttermilk porridge. They each ate three bowls of it, and then their mother put them to bed.

This is a picture of the bed! It opened like a cupboard right into the kitchen, and it was like going to bed on a shelf in the pantry.

The very next thing the Twins knew, it was morning, and there was Vrouw Vedder calling to them.

"It's market day, and the sun is almost up. Come Kit and Kat, if you want to go with Father," she said.

The Twins bounced out like two rubber balls. They ate some breakfast and then ran to the boat.

Father was there before them. He helped them into the boat and put them both on one seat, and told them to sit still. Then he got in and took the pole and pushed off.

Vrouw Vedder stood on the canal bank to see them pass.

"Be good children; mind Father, and don't get lost," she called after them.

Kit and Kat were very busy all the way to town, looking at the things to be seen on each side of the canal.

It was so early in the morning that the grass was all shiny with dew. Black and white cows were eating the rich green grass, and a few laborers were already in the fields.

They passed little groups of farm buildings, their red-tiled roofs shining in the morning sun; and the windmills threw long, long shadows across the fields.

The blue blossoms of the flax nodded to them from the canal bank; and once, they saw a stork fly over a mossy green roof, to her nest on the chimney, with a frog in her mouth.

They went under bridges and by little canals that opened into the main canal. They passed so close to some of the houses that Kit and Kat could see the white curtains blowing in the windows, and the pots of red geraniums standing on the sill. In one house the family waved their hands to Kit and Kat from the breakfast table, and a little farther on they passed a woman who was washing clothes in the canal. Other boats filled with vegetables and flowers of all colors passed them. And they were going to market too. Only no other boat had twins in it.

"Good day, neighbor Vedder," one man called out. "Are you taking a pair of fat pigs to market?"

By and by they came to the town. There were a great many boats in the canal here, and people calling back and forth to each other from them.

Kit and Kat saw a boat that the Captain's family lived in. It was like a floating house.

The Twins thought it must be grand to live on a boat like that, just going about from town to town, seeing new sights every day.

"We should never have to go to school at all," said Kit.

They wished their own boat were big enough to move about in; but Father told them they must sit very, very still all the time.

There were houses on each side of the canal, in the town, and people were clattering along over the pavement in their wooden shoes.

The market-place was an open square in the middle of the town. It had little booths and stalls all about it. The farmers brought their fresh vegetables and flowers, or whatever they had to sell, into these stalls, and then sat there waiting for customers.

Kit and Kat helped their father to unload the boat. Then they sat down on a box, and Father gave them each some bread and cheese to eat; for they were hungry again. They put the cheese between slices of bread and took bites, while they looked about.

Soon there were a good many people in the square. Most of them were women with market baskets on their arms. They went to the different stalls to see what they would buy for dinner.

A large woman with a big basket on her arm came along to the stall where Kit and Kat were sitting.

"Bless my heart!" she said. "Are you twins?"

"Yes, Ma'am," said Kit and Kat. And Kat said, "We're five years old."

"O my soul!" said the large woman. "So you are! What are your names?"

"Christopher and Katrina, but they call us Kit and Kat for short." It was Kat who said this. And Kit said,

"When we are four feet and a half high, we are going to 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
