Final check, weather device. Washington, D.C., Sept. 13. L.L. Stockman, also of the Bureau of Standards, Radium Division, uses a wave meter to check the radiometeorograph before attaching it to the parachute and the balloon. When the inflated bag breaks, which it usually does after several hours flying, the instrument is parachuted to the ground. Many times the instrument is found and returned to the bureau. The radiometeorograph contains two radio tubes, a miniature dry cell battery and devices which record and send the weather signals which, in turn, are recorded on a chronograph in Dr. Astin's bood [?] radio room.
