the
wood with pins or little bolts, or if the wheel bearing is of such
a nature that it revolves on its own journal, the journal can be
fastened to the end of the wood piece. Each of the wheels should
be provided with a sprocket; any chain sprocket of a bicycle may
be used. Fasten these sprockets on the outside of the wheels as
shown in Fig. 1. They can be set on over the bearing end and
secured with a set screw, or the original key can be employed. It
is best in cases like this to use the original parts. Make the
floor of the car of pieces of boards placed on the axles and
nailed, screwed or bolted, as shown at A. To erect the frame,
place uprights, C C C C, in position as shown, fastening the ends
to the base-boards and making

the roof line as at B, then put in the cross-pieces, G G. Seats, E
E, are simply boxes. The drive of the car is effected by using the
driving sprockets, D D, fitted to the crosspieces, G G, with the
original bearings. The parts are thereby secured to the car and
the chain placed on.

Key the cranks for turning to the upper sprocket's shaft and all
is ready. If there are sprocket gears and cranks on either side,
four boys may propel the car at one time. Considerable speed can
be made on smooth roads, but it is the best amusement to run a car
line on wooden tracks with a brake consisting of a piece of wooden
shaft, passing through a bore in the car floor, and fitted with a
leather covered pad as at H. A spiral spring holds up the brake
until pressure is applied by foot power, when the brake contacts
with the wooden track and checks the car.

The track plan is illustrated in Fig. 2. Get some boards and place
them end for end on other pieces set as ties. The main boards or
tracks, JJ, can be about 6 in. wide, to the edges of which nail
strips about 3/4 in. wide and about the

same height. The ties, I I, can be almost any box boards. Wire
nails are the best to use in putting the tracks together. The
sprocket connection with the chain is shown in Fig. 3. This
consists of the sprocket gear on the propelling shaft, and the
crank. The pedals may be removed and a chisel handle, or any tool
handle, substituted, so as to afford means for turning the

crank by hand power. Great fun can be had with the road, and,
furthermore, it can be made remunerative, as boys and girls can be
given rides for a p
