Sled Propelled by Revolving Wheels Turned by Cranks, the Pointed Nails Doing the Pushing
Two pieces or blocks of wood, 2 in. square and 4 in. long, were used as bearings. These were bored centrally through the long way, to receive the 1/2-in. rod just loose enough to make a good bearing. These bearings were supported by a pair of braces made of strap iron, about 1/4 in. thick and 3/4 in. wide. The length of the iron will depend on the size of the wheels and the height of the sled runner. The braces were shaped as shown. The center of the bearing hole must be as high from the surface of the ground as the distance the spoke ends are from the center of the hub hole.
The crank is then run through the bearing hole and a nut run on the threads and a washer placed against the nut. The wheel is then slipped on the axle, and another washer and nut run on tightly. Both wheels, bearings, cranks, and brackets are made alike. The brackets are fastened with small bolts to the sled top.—Contributed by Justin Stewart, Wallingford, Conn.
A Self-Feeding Match Box
With the addition of the simple device here illustrated, any match box can be converted into one of the self-feeding type. A piece of tin, or cardboard, is cut, as shown at A, the exact size depending on the match box used. The piece cut out is folded on the dotted lines, the cover on the match box is removed, and the part B pushed into the end of the box beneath the matches. The part B is twice as long as the depth of the box, therefore it enters the box as far as the line C. The flaps D rest against the outside of the box, and are held in place by the box cover. The matches feed into the box formed of the tin or cardboard as fast as used, while the burnt ones can be placed in the upper part E.

Corks-in-a-Box Trick
Procure a pill box and a clean cork. Cut two disks from the cork to fit in the box, and fasten one of the pieces centrally to the inside bottom of the pill box with glue.
