HOW TO MAKE A KITE WITHOUT A TAIL.

The following is the method of making a kite without a tail: All the

calculations necessary in order to obtain the different proportions are

based upon the length of the stick, A'A, employed. Such length being

found, we divide it by ten, and thus obtain what is called the unit of

length. With such unit it is very easy to obtain all the proportions. The

bow, K'K, consists of two pieces of osier each 5½ units in length, that

form, through their union, a total length of 7 units.

[Illustration: KITE WITHOUT A TAIL.]

After the bow has been constructed according to these measurements, it

only remains to fix it to the stick in such a way that it shall be two

units distant from the upper end of the stick. The balance, CC', whose

accuracy contributes much to the stability of the whole in the air,

consists of a string fixed at one end to the junction, D, of the bow and

stick, and at the other to the stick itself at a distance of three units

from the lower extremity. Next, a cord, B, is passed around the frame,

and the whole is covered with thin paper.

Before raising the kite, the string, which hangs from K', is made fast at

K in such a way as to cause the bow to curve backward. This curvature is

increased or diminished according to the force of the wind.

Nothing remains to be done but to attach the cord to the balance, and

raise the kite.--_La Nature_.
