After building a number of kites from a recent description in Amateur Mechanics I branched out and constructed the aeroplane kite shown in the illustration, which has excited considerable comment in the neighborhood on account of its appearance and behavior in the air.
The main frame consists of a center-stick, A, 31 in. long, and two cross-sticks, of which one, B, is 31 in. long and the other, C, 15 1/2 in. long. The location of the crosspieces on the centerpiece A is shown in the sketch, the front piece B being 1% in. from the end, and the rear piece C, 2 1/4 in. from the other end. The ends of the sticks have small notches cut to receive a string, D, which is run around the outside to make the outline of the frame and to brace the parts. Two cross-strings are placed at E and F, 7 in. from either end of the centerpiece A, other brace strings being crossed, as shown at G, and then tied to the cross-string F on both sides, as at H.

The long crosspiece B is curved upward to form a bow, the center of which should be 3 1/4 in. above the string by which its ends are tied together. The shorter crosspiece is bent and tied in the same manner to make the curve 2 1/2 in., and the centerpiece to curve 13/4 in., both upward. The front and rear parts, between the end and the cross-strings E and F, are covered with yellow tissue paper, which is pasted to the crosspieces and strings. The small wings L are purple tissue paper, 4 in. wide at M and tapering to a point at N.
The bridle string is attached on the centerpiece A at the junction of the crosspieces B and C, and must be adjusted for the size and weight of the kite. The kite is tailless and requires a steady breeze to make it float in the air currents like an aeroplane.
The bridle string and the bending of the sticks must be adjusted until the desired results are obtained. The bridle string should be tied so that it will about center under the crossstick B for the best results, but a slight change from this location may be necessary to make the kite ride the air currents properly. The center of gravity will not be the same in the construction of each kite and the string can be located only by trial, after which it is permanently fastened.
