"That's right," cried Bert. "It's the only way. If we go wandering about, looking for a shelter, we may get into trouble. We'll make one of our own. There's a good place, over by that clump of trees. We can cut down some branches, stand them up around the trees and make a sort of tent. Then, when the snow has covered it, we'll be real warm."

"Well, let's start building that snow tent," proposed Harry. "It will give us something to do, and moving about is warmer than standing still. I know that much, anyhow."

"Yes, it is," agreed Bert. "Come on, girls. Harry and I will cut the branches and you can stack them up."

Bert led the way to where three trees grew close together in a sort of triangle. The trees had low branches and it would be an easy matter to stand other branches up against them, one end on the ground, and so make a fairly good shelter.

With their pocket-knives Bert and Harry began cutting branches from the evergreen trees that grew all about. As fast as they were cut the girls took them, and piled them up as best they could. All the while the wind blew the falling snow about, and it became darker.

"Oh, if we only had some sort of a fire!" exclaimed Nan.

"A fire?" said her brother.

"That's so," agreed Dorothy. "It would not be so lonesome then, and it—would scare away—the bears!" and she looked over her shoulder in some fear.

"Bears!" cried Bert "There aren't any within a hundred miles, unless they're tame ones. But we might as well have a fire. I never thought of that. I've got a box of matches. Harry, if you'll gather wood, and the fire, I'll keep on cutting branches. We've got almost enough, anyhow."

"Sure, I will!" said the other boy, and soon he had scraped away the snow from a spot on the ground, and had piled some sticks on it. He managed to find some dry twigs and leaves in a hollow stump, and these served to start a blaze. The wood was rather wet, and it smoked a good deal, but soon some of the fagots had caught and there was a cheerful fire reflecting redly on the white snow that was falling faster than ever.
