Soon the girls came running up to the ice boat. They had been racing about, they said, to get warm, and Betty and Amy, sitting amid the furs and blankets, rather wished they had done the same, for they were quite chilly in spite of their coverings.

"I'm going to make a try for it," explained Allen. "We may not be able to go far, for the snow is rather wet and heavy, and it may clog the runners. But we'd better make a start, anyhow. It seems to be slackening up a bit."

They piled into the ice boat, and the sail was hoisted. The Spider darted off, after a moment's hesitation.

"Hurray!" cried Will. "We're moving."

"And that's about all," said Allen in a low voice. "Don't crow until you're out of the woods. This snow is worse than I thought it was."

For a time the ice boat went along well, halting occasionally as masses of snow clogged the runners. Then there came a jolt, and a puff of wind nearly upset it, as the craft did not properly answer the helm.

"Oh, my!" screamed Grace, as she clutched Betty. "We are going to upset."

"No, we're not!" declared Allen, as he loosed the halyards, letting the sail come down on the run. "I guess we'll have to abandon the Spider," he went on, "and tramp it. The snow is too heavy. We may upset."

"Well, the girls are good walkers," observed Frank.

"Which is a blessing," spoke Will. "Out of the Spider into the—frying-pan. Don't you ask me to carry you, Sis," and he looked at his sister.
