Overhead is a captive or "kite" balloon. As used in naval work, it is attached to an anchored or moving ship by a small steel cable, by which it is regulated for purposes of observation. The tubular surfaces which give the balloon the appearance of an elephant's head are not filled with hydrogen gas, but are inflated by the winds at high altitudes, thus keeping the balloon relatively steady like a kite with a long tail. The stationary balloon is such a good target for anti-aircraft guns that the observers are supplied with parachutes, the type of which appears on page 341.]
