"We'll all help you look for them," said Ben. "Did you ever teach any of them the trick of opening the cage door?" he asked.

"No," replied Sam. "I don't believe they could do that, for the door was fastened on the outside, and white mice haven't paws like a trained monkey. Maybe I didn't fasten the cage door good last night."

"Oh, Bunny!" cried Sue. "Wouldn't it be fun if we could send and get Mr.

Winkler's monkey w.a.n.go for our circus? Wouldn't it?"

"Yes, maybe it would," replied Bunny. "But I don't guess we could do it.

Come on, Sue, I'm going to look for the white mice."

"All right," Sue said. Maybe some little girls would be afraid of mice, white, black or gray. But Sue was not. Perhaps it was because she knew Bunny was going to be with her. Then, too, Sue was very anxious to have the circus as good as it could be made, and if the mice were missing some of the people who came might not like it. So Sue and Bunny said they would help hunt for the lost white mice.

With the big boys, the children looked all around the animal tent. The ground had been covered with straw, and the mice might be hiding in this, or among the boxes and barrels in the tent. But, look as every one did, the mice were not to be found.

"What's in that box?" asked Sue, pointing to one covered with a horse blanket.

"That's the lion," answered Bunker Blue. "But don't be afraid," he went on, as he saw Sue step to one side. "He's asleep now. Besides he can't hurt anyone. You'll see, when we have the circus."

No one knew where the white mice had gone. Even Splash could not find them, though both Bunny and Sue told their dog to look for Sam's pets.

"I guess Splash isn't a rat dog," said Ben.

"No, and I'm glad he isn't," Sam said. "Rat dogs might think white mice were made for them to shake and kill, just as they shake and kill the other kind of rats and mice. I'd rather lose my white mice, and never see them again, than have them killed."

But, even though the white mice were missing, the circus would go on just the same. And now began a busy time for all the big boys. The show would be given in two more days, and there was much to be done before that time.

Sam and Bunker Blue had painted some signs which they tacked up on Grandpa Brown's barn, as well as on the barns of some of the other farmers. Everybody was invited to come to the circus, and those who wanted to could give a little money to help pay for the hire of the big tent. Many of the farmers and their wives said they would do this.

One by one the animal cages, which were just wooden boxes with wooden slats nailed in front, were brought into the animal tent. They were put around in a circle on the straw which covered the ground.

In the other tent the boys had made a little wooden platform, like a stage. They had put up trapezes and bars, on which they could do all sorts of tricks, such as hanging by their hands, by their heels and even by their chins.

No one except themselves knew what Bunny and his sister Sue were going to do. The children had kept their secret well. They had asked their grandma for two old bed sheets, and she had let them take the white pieces of cloth. Bunny and Sue were making something in the harness room of the barn, and they kept the door shut so no one could look in.

It was the night before the circus, and Bunny and Sue had gone to bed.

They were almost asleep when, in the next room, they heard their mother call:

"Oh, Walter!" exclaimed Mrs. Brown to her husband. "There's something under my bed. I'm sure it's one of the animals from the boys' circus! Do look and see what it is!"

"Oh, it can't be anything," said Mr. Brown. "All the animals are shut up in the tent. Besides, they are only make-believe animals, anyhow."

"Well, I'm sure _something_ is under my bed!" said Mrs. Brown. "I heard it move. Please look!"

Mr. Brown looked. Sue and Bunny wondered what it was their papa would find. They heard him say:

"Oh, it's nothing but a piece of white paper. You heard it rattle in the wind. Come and see for yourself."

Bunny and Sue heard their mother cross the room. She stooped down to look under the bed. Then she cried:

"Oh, Walter! It's alive! It isn't paper at all. It's coming out!"

"Why, so it is!" said Mr. Brown. "I wonder what--?"

Then Mrs. Brown screamed, and Mr. Brown laughed.

"Oh, it's a mouse! It's a rat! It's a whole lot of mice!" said Bunny's mother.

"Yes, it's a whole lot of mice, and they're white!" said Mr. Brown with a jolly laugh. "Hurrah! We've found the lost white mice from the boys'

circus! You needn't be afraid of them!"

Mrs. Brown did not scream any more. She was not afraid of white mice.

Bunny and Sue ran into the room where their mother and father were.

There they saw their father picking up the white mice in his hands, and petting them. The mice seemed to like it.

"Oh, where did you find them?" cried Bunny.

"Under our bed," his mother said.

"Oh, how glad Sam will be!" said Sue. "Now we can have the circus all right."

And so the white mice were found. They had gotten out of their cage in the tent, and had, somehow or other, found their way to the farmhouse.

There they had hid themselves away, until that night when they came out into Mr. Brown's room.

"Well, I'm glad they are found," said Mrs. Brown. "Give them something to eat, and put them in a box until morning."

This Mr. Brown did, after Bunny and Sue had held in their hands the queer pets, which had such funny pink eyes.

"I want to see them do some tricks," said Sue.

"Sam can hitch them to a little cart and drive them," said Bunny. "He told me so."

The mice were put safely away ready for the circus the next day, and soon the house was quiet, with everyone asleep.

The sun was brightly shining. There was just enough wind to make it cool, and the weather was perfectly fine for the circus. Bunny, Sue, Bunker and Ben were up early that morning, for there was still much to do.

Sam, the boy who owned the white mice, came over to ask if his pets had been found. And when told that they were safe in a box down in the cellar, he was very happy indeed.

"I must put them back in their cage, and let them practise a few of their tricks," he said. "They may have forgotten some as they have been away from me so long."

Bunny and Sue had to get their things ready. They were to have a little place in the big tent to dress and get ready for their act. They were the smallest folks in the circus, and everyone was anxious to see what they would do.

On the big, as well as on the little, tent the boys had fastened flags.

Some were the regular stars and stripes of our own country, and other flags were just pieces of bright-colored cloth that the boys' mothers had given them. But the tents looked very pretty in the bright and sparkling sunshine, with the gay banners fluttering.

Just as in a real circus, the people who came were to go first into the animal tent, and from there on into the one with the seats, where they would watch the performance.

Soon after dinner the farmers and their wives, with such of their children who were not taking part in the show, began to come.

"Right this way to see the wild animals!" called Ben Hall, who was making believe he was a lion tamer. "This way for the wild animals! Come one! Come all!"
