"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 snow on," he said.
"Well, it's easy enough to shovel some snow on, and pack it down hard," answered Bert. "You get your shovel and begin."
Freddie was delighted to do this, and was soon tossing up on the slanting boards shovelful after shovelful of snow. When Bert had finished nailing the platform on top of the posts, which were about seven feet high, he helped Freddie pile on the snow. When Flossie came out, after her brothers had been working for some time, the little girl cried:
"Oh, how did that hill get in our yard?" for by this time all the wood had been covered with the snow Freddie and Bert had piled on.
