"What shall we do?" cried Dorothy, who was not used to being out in such a blow.
"Keep on—that's the only thing to do," answered Bert. "We will go as far as we can in the boat and then we'll walk."
"Walk to Snow Lodge!" cried Nan. "We could never do it!"
"Oh, it isn't so far now," said her brother.
The snow fell so fast that soon the ice-boat went slower and slower. Finally it stopped altogether, the runners clogged with snow. The wind blowing on the sail nearly turned the craft over.
"Cast off those ropes!" cried Bert to Harry. "We'll have to leave her here and walk on."
The sail was lowered, the blankets and robes were picked up to be carried, and the four girls and boys set out over the ice.
"We must keep near the shore," said Bert, "Snow Lodge is right on the shore of the lake, and we can't miss it."
"Oh, suppose we did, and had to stay out all night?" cried Dorothy.
"We won't worry until we have to," spoke Nan.
