Later on the Bobbseys went back to school, where they had plenty of fun, and when they were at Snow Lodge there were some strange happenings, as there were also on the houseboat Bluebird. There was a stowaway boy—but there! I had better let you read the book for yourself.

The Bobbsey twins spent some time at Meadow Brook, but there was always a question whether they had better times there or "At Home," which is the name of the book just before this one.

You, who have read that book, will remember that Flossie and Freddie found, in a big snow storm, the lost father of Tommy Todd, a boy who lived with his grandmother in a poor section of Lakeport. And it was still that same Winter, after Tommy's father had come home, that we find the Bobbsey twins skating on the ice, having just missed being run into by the ice-boat.

"My! but that was a narrow escape!" exclaimed Nan, as she skated slowly about. "My heart is beating fast yet."

"So's mine," added Flossie. "Did he do it on purpose?"

"No, indeed!" exclaimed Bert. "I guess Mr. Watson wouldn't do a thing like that! He was looking after the ropes of the sail, or doing something to the steering rudder, and that's why he didn't see you and Freddie."

"What makes an ice-boat go?" asked Freddie.

"The wind blows it, just as the wind blows a sailboat," explained Bert, looking down the lake after the ice-boat.

"But it hasn't any cabin to it like a real boat," went on Freddie. "And it doesn't go in the water. Where do the people sit?"

"An ice-boat is like this," said Bert, and with the sharp heel end of his skate he drew a picture on the ice. "You take two long pieces of wood, and fasten them together like a cross—almost the same as when you start to make a kite," he went on. "On each end of the short cross there are double runners, like skates, only bigger. And at the end of the long stick, at the back, is another runner, and this moves, and has a handle to it like the rudder on a boat. They steer the ice-boat with this handle.
