"Is that the name of your horse?"

"Yes. Bucksaw is his name. Pretty good for a woodchopper's horse, I guess," and the old man smiled.

While Flossie and Freddie were being driven home by the woodchopper, Mr. and Mrs. Bobbsey, with Bert and Nan, left far behind on the ice when the Bird upset, were much worried and excited.

"What can we do?" cried Bert.

"We must go after those children!" exclaimed Mrs. Bobbsey.

"That's what I'm going to do," Mr. Bobbsey remarked.

"If I could borrow one of those ice-boats over there," put in Bert, pointing toward some on the other side of the lake, "I could sail down and get them."

"No more ice-boats to-day!" said Mrs. Bobbsey. "Oh, I do hope nothing happens to Flossie and Freddie!"

"I don't believe they'll be hurt," said their father. "Even if they fall out they can't get much of a bump on the ice, and if they run ashore, as they're likely to do, they'll only fall in the snow. Don't worry."

"But we must go after them!" cried his wife.
