"Yes, I could eat something myself," admitted Harry. "I guess this air
makes you hungry."

"We--we haven't got enough for all of us--I guess," said Freddie,
looking wistfully at his package.

"Don't worry!" answered Harry with a laugh. "I won't take any,
Freddie. I can wait until we get home."

Thereupon the two smaller twins proceeded to eat the lunch they had
brought, doing this while trudging through the snow toward the little
hill.

They reached the top, and stood for a time looking over the broad
snow-covered expanse of lake and woods. Then they started down. But it
was not easy work, especially for Flossie and Freddie, so the whole
party stopped for a rest about half way.

They were sitting under a sheltering tree, looking at some flitting
snow-birds, when from behind them came a curious sound. Bert looked
back, and leaping to his feet, cried: "It's a snow slide! A snow
slide! It's coming right toward us!"

Indeed a great drift of white snow was sliding down the side of the
hill toward the children. A great white ball seemed to have started
it, and as Harry looked up he gave a cry of surprise.

"I saw a boy up there!" he said. "He pushed that snowball on us!"
