Sidney W. McCuskey, assistant in Astronomy on the Observatory staff, will give the lecture which is scheduled for 7.30 o'clock. It will be followed by telescopic observations of celestial objects, if the weather permits, and exhibits illustrating the work of the Observatory will be explained...
...survey the possibility of establishing depots for U. S. airlines to the Antipodes. With similar lack of fanfare, twelve youngsters from Honolulu's Kamehameha School were thereafter packed aboard the Coast Guard Cutter Itasca, taken out to Jarvis, Howland and Baker Islands, established in crews of four as weather observers. Along with their instruments for noting wind velocity, rainfall and cloud formations, the boys had to be supplied with everything else to support life. None of the islands is more than 20 ft. above sealevel; none is forested; none has fresh water. Accordingly, camping equipment was landed as well...
...device has been installed in the Army airplane that makes daily weather ascents from the Boston airport for the Weather Bureau. The signals are recorded by a receiving set up at Blue Hill. Here the signals are marked graphically on a revolving drum...
Perfection of the instrument which transmits its signals on the ultra-short wavelength of 5 meters, was made possible by a study of high frequency radio transmission and receiving between the weather station on top of Mount Washington and Blue Hill...
Mechanics of the instrument are simple. The whole device weighs, with batteries, about three pounds. It transmits a steady humming signal broken every thirty seconds. A rotating cylinder, run by clockwork, makes electrical contact with Tungsten needles which move as the weather changes. The contact thus made transmits additional signals, which, are recorded on a graph at the receiving point, and from this graph, is reduced the data...
