A Folding Ice Sled
On a smooth ice surface, or on hard snow, the sled shown will run easily, and a skater can push another with surprising speed by a light push on the shoulders while the rider rests his feet on the front of the runners. The sled is light, and it can be folded up and carried under the arm. It is also handy for putting on the skates, or for use in a crowded car.
Any camp stool will do for the main part of the sled. Holes are bored in the ends of the legs to receive the lugs on the runners snugly. If the builder is not equipped with a forge, a blacksmith will make the runners cheaply. The sliding surfaces of the runners are smoothed with a file.—Contributed by Thomas Lappin, Portland, Ore.
