also, for it was nearly supper
time.

"That was a fine thing you did--saving my little brother and sister from
getting hurt, Tommy," said Bert, as he walked along, pulling the
bob-sled after him. "I'll tell my father and mother what you did."

"Oh, that wasn't anything," Tommy said, "Anybody would have done the
same if he had been in my place."

"Yes, but not everybody would have steered as quickly as you did. You
surely can steer a bob! The next time you come out on the hill I'll let
you steer a lot."

"Thanks," answered Tommy.

Mr. Bobbsey was very much pleased that night when he learned how good
Tommy had been.

"I must keep an eye on that boy," he said. "I think he will make a good
man. I'll help him all I can. He is so anxious to run errands and do
work about the lumber yard to earn money. How is his grandmother?" Mr.
Bobbsey asked his wife. "Have you been to see her lately?"

"Yes, but she isn't very well. She can't sew as much as she used to, but
some ladies and myself are looking after her. Oh, I don't like to think
of the danger Flossie and Freddie were in on that hill!"

"Oh, well, maybe they wouldn't have been hurt much," said Bert.

"Just the same, I think they would be safer on a little hill of their
own," said Mr. Bobbsey. "Can't you find one for them, Bert?"

"Yes, I guess I could make a hill in the back yard for them."

"Make a hill? Why, Bert Bobbsey, nobody can _make_ a hill!" cried
Freddie. "It just has to _grow_."

"Well, I think I can make one. Just wait," was what Bert said.

The next Saturday he was busy in the back yard with some boards, a
hammer and some nails.

"What are you doing?" asked Freddie, who had gotten up later than usual
that morning.

"Making a little hill for you and Flossie."

"You can't do it," said Freddie. "Nobody can _make_ a hill!"

But he watched what his brother was doing. Bert set some posts in the
ground, though it was hard to dig, for the earth was frozen. But the
posts did not have to go in very deep. From the top of the posts to the
ground Bert next slanted two long boards, bracing them on the under side
with shorter posts. Then he made a little platform by nailing boards
from the tops of the first two posts to two others which he placed a
little back of them.

"Why say, that does begin to look like a hill!" exclaimed Freddie, for
the slanting boards were just like a slanting hill of earth. "Only you
can't slide down on that 'cause it hasn't any
