Suchlength being found, we divide it by ten,and thus obtain what is called the unit ( flength. With such unit it is very easy toobtain all the proportions. The bow,KK, consists of two pieces of osier eachfive and a half units in length, that form,through their union, or lap, a total lengthof seven units. After the bow has been constructedaccording to these measurements, it onlyremains to fix it to the stick in such away that it shall be two units distantfrom the upper end of the stick. Thebalance, or belly band, CC, whose accuracy contributes much to thestability of the whole in the air, consists of a string fixed at one endto the junction, D, of the bow and stick, and at the other to the stickitself at a distance of three units from the lower extremity. Next,a cord, B, is passed around the frame, and the whole is covered withthin paper. Before raising the kite, the string, which hangs from K, is made fast. AIR-POWER MOTORS AND APPLIANCES. 147 at K in such a way as to cause the bow to curve backward. Thiscurvature is increased or diminished according to the force of the remains to be done but to attach the cord to the balance,or belly band, and raise the kite. 361 THE EDDY TAILLESS KITE. The sticks should bemade of clear spruce, as this has been found to be less liable to bend under strain or breakat the cross stick. Cross section of eachstick is y^g- by -J inch. Kite stick A B =68y*Q^ inches. Kite stick C D = 60inches. O = center of grav-ity, which is 35 percent of C D from thetop of C D. C E = 18 per centof C D in both strongand hght wind kites. T
