These devices are usually suspended from the kite line. It is necessary to have enough suspension cords attached to prevent twisting up with the main line. Most of the devices will float out and have some lifting power of their own, but some will require a kite that can sustain some weight, in some cases a pound or more.
Flags and Banners. One of the prettiest attachments is the American flag. This can be attached in two ways: first by means of a vertical stick of some weight, Fig. 162, and second by using the horizontal stick, as in Fig. 163. A pleasing trick is to have the flag folded (do not wind on the stick) and covered, tied loosely with bow-knots that are easily untied, and when the flag is well up, the tripping string is pulled and the flag released. The string of the bow-knot passes down the kite line thru little loops of wire attached to the main line to prevent the tripping string from getting twisted therein. If two are operating, one can stand at a little distance so as not to get the two strings twisted, and thus avoid the wire loops.

Banners are used sometimes for schools, sometimes for advertising and sometimes for just no particular purpose but the pleasure of doing it. A few banners are shown: Fig. 164 represents the Grand Avenue School, Fig. 165 the Hobart Boulevard School, Fig. 166, Vermont Avenue, and Fig. 167, the Tenth Street School. Fig. 168 shows how the banners are attached.
The wireless has a great attraction for most boys. Some attach antennae to the kite, others drop a number of wires from the kite line, as in Fig. 169. A stick is suspended similar to a banner, except that it requires only two suspension cords; another stick hangs by the wires about ten feet below, and below this the wires come together and a wire follows the kite line to the receiver and to the ground. Caution is here given against the use of a wire kite line. One boy tried this and when the kite lowered in a lull of the breeze the wire crossed the trolley line and in the mix-up the boy became entangled in the line by attempting to get his kite up again, and received quite a shock; but there was no serious results. His instrument and attachments were working splendidly. The winding of the coil is a very good problem for any boy.
Some boys are interested in photography, and the kite gives opportunity for taking bird's-eye views. The kodak must rest on a framework and the tripping line be so attached as not to cause the instrument to swing when the shutter is snapped. The tripping can be accommodated by means of the rear suspension cord, Fig. 170. The shutter should trip very easily so as to cause as little swinging as possible. An extension of the lever might be an advantage. The two sticks of the framework should be halved together so as to bring the upper surfaces level. A screw-eye placed in the cross-stick directly below the tripping lever holds the tripping string so that it draws on the camera in line with its own seating on the framework, and causes the minimum amount of swaying. Figs. 171 and 172 were taken on a kite line that was sent up from the Y. M. C. A. building. The speck of white shown on the roof near the ventilator is the operator. Figs. 173 and 174 were taken by a twelve year old boy and while not as high as the first is a very good start.
