nd strengthened by diagonal wires and guy wires. The
horizontal rudder is also immovable and its function is to prevent
the machine from diving, and also to keep it steady in its flight.
The rudders are fastened to the glider by the two rudder sticks,
and these sticks are held rigid by diagonal wire and also by guy
wires leading to the sides of the main frames as shown in Fig. 1.
The two arm sticks should be spaced about 13 in. apart and bolted
to the long beams in the center of the opening in the lower plane
where the operator is to take his position.

The glider should be examined to see

[Illustration: Details of the Glider]

that the frame is not warped or twisted. The surfaces must be true
or the machine will be hard to balance when in flight. To make a
glide, take the glider to the top of a hill, get in between the
arm sticks and lift the machine up until the arm sticks are under
the arms as shown run a few steps against the wind and leap from
the ground. You will find that the machine has a surprising amount
of lift, and if the weight of the body is in the right place you
will go shooting down the hillside in free flight. The landing is
made by pushing the weight of the body backwards. This will cause
the glider to tip up in front, slacken speed and settle. The
operator can then land safely and gently on his feet. Of course,
the beginner should learn by taking short jumps, gradually
increasing the distance as he gains skill and experience in
balancing and landing.

The proper position of the body is slightly ahead of the center of
the planes, but this must be found by experience. The machine
should not be used in winds blowing faster than 15 miles an hour.
Glides are always made against the wind, and the balancing is done
by moving the legs. The higher the starting point the farther one
may fly. Great care should be exercised in making landings;
otherwise the operator might suffer a sprained ankle or perhaps a
broken limb. The illustration shows two lines of flight from a
hilltop, the glider travels on the upper line caused by the body
of the operator taking a position a little back of the proper
place, and on the lower line he changes his position from front to
back while flying, which causes the dip in the line.

This is a diversion in which two boys personate a Centaur, a
creature of Greek mythology, half man and half horse. One of the
