An inexpensive merry-go-round can be made of a single pole set in the ground where there is sufficient vacant space for the turning of the ropes. The pole may be of gas pipe or wood, long enough to extend about 12 ft. above the ground. An iron wheel is attached on the upper end so that it will revolve easily on an axle, which may be an iron pin driven into the post. A few iron washers placed on the pin under the wheel will reduce the friction.
Ill: The Ropes being Tied to the Wheel Rim will Easily Turn around the Pole
Ropes of varying lengths are tied to the rim of the wheel. The rider takes hold of a rope and runs around the pole to start the wheel in motion, then he swings clear of the ground. Streamers of different colors and flowers for special occasions may be attached to make a pretty display. - Contributed by J. Bert Mitchell, Wichita, Kans.
