"It's Freddie's turn now," said Bert, and down went Freddie.

Then the Bobbsey twins had lots of fun on the "made" hill. They invited Johnnie Wilson and Alice Boyd over to coast with them, and the four little ones had a grand time.

"And they are in no danger, that is the nicest part of it," Mrs. Bobbsey said. "I don't have to worry about them now. I'm so glad you built the hill, Bert."

"I'm going to build something else," said Bert.

"What?" asked Nan.

"Snowshoes," was his answer.

"What are snowshoes?" Freddie demanded

"Shoes made so you can walk on top of the soft snow instead of sinking down in it," Bert replied. "Of course I can't make the kind the Indians and hunters make, which look something like lawn tennis rackets, but I know how to make another kind. I saw a picture of them in a book."

But before Bert started to make his snowshoes he made the little hill better for coasting. That night he poured water on the snow that covered it, and, as the weather was cold, the water and snow froze into a glaring stretch of ice.

And my! how Flossie and Freddie did whizz down the hill on their sleds then. It was perfectly safe, though, for Bert had put little strips of wood on the edges of the wooden hill, so the sleds would not slide off to one side.
