��The connecting link between the front and rear axle is made up of five pieces of ash which furnishes the spring to ease the rider. Driving attachments are fastened to these pieces

��Then fasten the ends to a cross-piece on the slats, spreading them out at the bottom like the shape of an inverted V. The steering wheel can be made, if de- sired, or it can be purchased. A wheel may be obtained such as is used in the place of handlebars on a bicycle. This is fastened to the end of the post.

The steering is accomplished by an ar- rangement of five pulleys of the drum- cable variety. Four 2-in. pulleys are placed under the frame; two on a ;^8-iri- rod placed directly under the steering post, and at the same angle as the post over which the cable passes. The other two are placed, one on each side of the frame, outside of the slats. One of them should line with the pulley next to the post block and the other with its mate. The drum la'ge pulley should be 3 in. long and 3 in. in diameter, and it should

��be placed close to the top of the block on top of the frame. It is fastened to the steering post with a long wood screw, which goes through a hole bored through the center of the pulley, and a similar hole drilled through the post. The hole in the post should be a sliding fit for the screw and the hole in the pulley should be a tight fit. Fasten a 6-ft. length of wire to one side of the front axle. Pass it around the pulley under the frame to a pulley on the shaft under the post and then to the drum on the post. Wind four turns around the drum, and run the end down under the other pulley on the shaft. Then pass it around the outside pulley and fasten to the other end of the a.xle.

The lamp was made from a large oil can. The spout was removed and the hole reamed out to receive the screw end of a 12-candle-povver electric globe. The
