"Well, come all the way up, and stand out of the way!" ordered Russ. "The train's going to start. Toot! Toot! All aboard!"

Laddie hurried up the last few steps and took his place in a corner, out of the way of the scooter with Mun Bun on it. A girl with light, fluffy hair, and bright, smiling eyes, followed him. She was a year younger than Russ, who was eight years old.

"Oh, Rose!" cried Violet, as she saw her older sister. "We're having such fun!"

"You can have a ride, too, Rose! Can't she?" asked Mun Bun of Russ. "Go on, push me!"

"Yes, we'll all take turns having rides," said Russ. "If I could find another roller skate I'd make another scooter, and then we could have races."

"If we had two we could make believe they were two trains, and have 'em bump into each other and have collisions and all that!" cried Laddie. "That'll be fun! Come on, let's do it!"

"We'll have to get another board and another skate," said Russ. "We'll look after a while. Now I'm going to give Mun Bun a ride."

He shoved the scooter across the floor of the attic. Mun Bun kept tight hold with his chubby hands of the edges of the board, in the middle of which he sat, between the two pieces of roller skate that made wheels for the scooter.

"Hi! Yi!" yelled Mun Bun. "This is fun!"

"Now it's my turn!" exclaimed Margy. "Get off, Mun Bun."
