scooter down on the floor.

"I'm going to get on!" cried Mun Bun.

"Wait until I put it straight," called Russ. "Then you can have a longer
ride."

He took the board, with the roller skate wheels on either end, to a far
corner of the attic. From there it could be pushed all the way across to
the other wall.

Just as Mun Bun was about to take his place, so that Russ could push him
across the attic floor, footsteps were heard coming up the stairs that
led to the third story of the Bunker house.

Then a boy's voice called:

"What are you doing?"

"Riding on a scooter Russ made," answered Violet. "Oh, it's lots of fun!
Come on, Laddie!"

Laddie was Violet's twin brother, and he had the same kind of curly hair
and gray eyes as had his sister.

"Did you make that?" asked Laddie of Russ.

"Sure."

"Will it hold me?"

"Sure. It'll hold me. I had a ride on it."

"Say, that's great!" cried Laddie. "We can have lots of fun on that! I'm
glad I came up."

"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."

"I have to have a ride back! I've got to have a ride back!" he cried.
"Russ said he'd ride me across the attic and back again! Didn't
