"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.
"And where the two big sticks cross they put up the tall mast and make the sail fast to that. Then when the wind blows it sends the ice-boat over the ice as fast as anything."
"It sure does go fast," said Tommy Todd. "Look! He's almost at the end of the lake now."
