short length of stiff spiral spring to the center hole in the bar and fasten the other end to a cross bar of wood as shown. Run a length of cable wire from the center of the bar to the foot pedal in front. Run this cable straight on the center slat for half the distance to the pedal and then turn it off to the pedal and fasten it.

All braces are made of ^ g by J-g-in. strap iron. The braces, from the frame to the axle, are twisted in the center to make them more rigid. After placing the uprights, these braces can be easily measured and fitted in place. The end stays should be bent at right angles at the proper height and then they should run to the upright as shown. The side braces from the frame to the axle are run all the way across the frame, joining in the center of the wood cross piece. Turn three or more screws in each piece, securely fas- tening them in place, as these u{irights form the main support for the axle ends. The seat was made of an old chair cut down to a convenient size.

��The motor wheel is provided with fastenings for attaching it to the rear cross-piece of the frame. Provision may be made for lifting the wheel from the ground by means of a foot pedal for stop- ping and starting the buckboard while the motor is still running. This provides a way to start the engine without running the machine along the road.

��Priming an Automobile Engine to Start It Easily

IN winter weather a primer for the automobile motor is very essential and the idea here illustrated combines prac- ticability with simplicity at small cost and is convenient as the hood over the engine does not need to be raised. It is made as follows: Drill a U-in. hole in the intake manifold pipe and fit a brass cocTi in it, care being taken in drilling and tapping the threads so that the aluminum is not ruptured. Drill a 3/16-in. hole in the top of the carburetor float chamber and con- nect it as shown. The bottom end of the primer tube must be so placed in the carburetor float chamber that it does not interfere with the float, but the end of it must enter under the gasoline level. To prime the motor, simply open the valve on the intake manifold and the motor will draw in raw gas, automatically priming itself and greatly facilitating the starting
