When the ice is too thin for skating and the snow is not right for skis, about the only thing to do is to stay in the house. A club will help to fill in between and also furnishes good exercise for the muscles of the arm. A boomerang can be made of a piece of well seasoned hickory plank. The plank is well steamed in a wash boiler or other large kettle and then bent to a nice curve, as shown in Fig. 1. It is held in this curve until dry, with two pieces nailed on the sides as shown.

Illustration: Bending and Cutting the Wood

After the piece is thoroughly dried out, remove the side pieces and cut it into sections with a saw, as shown in Fig. 2. The pieces are then dressed round. A piece of plank 12 in. wide and 2 ft. long will make six .

To throw a , grasp it and hold the same as a club, with the hollow side away from you. Practice first at some object about 25 ft. distant, and in a short time the thrower will be able to hit the mark over 100 ft. away. Any worker in wood can turn out a great number of boomerangs cheaply. --Contributed by J. E. Noble, Toronto, Ontario.
