"Not so fast as this. I can't make my nose work—I can't get any air!"

Indeed they were sailing even more swiftly than when Bert was steering, and Flossie was frightened. So was Freddie, but he was not so quick to say so.

"Please stop the boat!" cried Flossie again.

"Well, I'll try," promised Freddie. "I guess this is the rope you pull on," and he took hold of the one fast to the end of the sail—the rope that kept the big piece of white canvas from blowing away.

Freddie pulled on this, but it could not have been the right rope, or else he pulled it the wrong way, for, in an instant, the ice-boat seemed to "stand on its ear," as Bert spoke of it afterward. Flossie and Freddie were almost tossed out.

"Oh, don't do that!" cried the little girl.

"I—I didn't mean to," Freddie told her. "I guess I pulled on the wrong rope. Here's another. I'll try that."

By this time the ice-boat was more than two miles down the lake, for the wind was blowing hard and the Bird sailed swiftly. The children could not see their father, mother, Bert or Nan now. They would soon be at the end of the lake, and before them Flossie and Freddie could see big drifts of snow near the edge of the frozen lake and between it and the forest beyond.

"I—I guess we'd better stop pretty soon," faltered Freddie. "If we don't we'll run ashore."

With all his strength, he pulled on another rope, at the same time shoving the tiller over as far from him as it would go. The result was a surprise to him and to Flossie. The ice-boat turned quickly, and then, like a frightened horse, it darted toward shore.
