Janet raised the window and listened. Just then Ted shouted:

"Come on out, girls, and help us build a snow house. We're going to make the biggest snow house you ever saw!"

"And when it's finished you can have a tea party in it," added Tom.

"Oh, what lovely fun that will be!" cried Mary.

Soon the boys and girls, with Skyrocket frolicking around them, began making the snow house. The sun had so warmed the snow that it packed well.

First a number of big snowballs were rolled and placed one after the other in the form of a square on the ground. This was to be the foundation of the house.

Other snowballs were lifted on top of the first large ones, and snow packed in the cracks until, when afternoon came, there were four walls of snow, much higher than the heads of the children.

"It looks more like a fort than a snow house," said Lola.

"We've got to put the roof on," Tom answered. "How we going to do that, Ted?"

"I don't know," was the reply. "I never made such a big snow house. If we make the roof only of snow it will fall in on us."
