Fig. 58. Square cellular kite
"Another kind of a kite, known as the cellular kite is shown in [Fig. 58]. This is made by forming two square frames N. O., divided into nine compartments each and connected together by a light rod at r, the fulcrum or string being at P, the air pressure at T. The whole forms a good, strong kite, but it is not able to carry much weight, on account of the equipoise being self adjusted in accordance with the constant pressure and surface. The equipoise is due to the current being cut by the edges a a´, and diverted into the cellular divisions of each area. This being the case, any upward or downward tendency of a a´, would be counterbalanced by the effect on the other side and the kite would naturally adjust itself on the opposite side. We are not dependent upon any particular shape for obtaining a good serviceable kite—like the plane made kite, the cellular one may be of any shape. I show you one here, at [Fig. 59], having a circular rim, with thin tubes inserted in such a manner that the current of wind will rush through when the machine is in the air. The two portions, A and B, are held together by a rod in a similar manner to the square kites, and the cord or fulcrum is fastened to the rod at R.

"A number of kites may be sent up at once, all attached to the same string, if properly adjusted. Here are six square cellular kites looped together, shown at [Fig. 60]. They may be made of any suitable size, but need not be all of one size, though each pair would be better if made the same size. They may be looped up, as shown, and the point S may be loaded lightly; it will help to steady the kite and keep it from swaying.
