Automatic "Mail Man" Exhibited at-New York Exposition The "wireless mail man," a new invention was exhibit-at the radio exposition which opened in New York on March 7. It was a wirelessly directed automobile, invented by E. P. Glavin, and distributed mail and newspapers to the delegates assembled on the roof garden of the Pennsylmania Hotel, where the exhibit was held. Sixty separate exhibits representing the product of leading manufacturers of radio equipment, were displayed.
A district council] composed of two delegates from each of the 25 radio clubs in the New York district gave the exhibition an amateur flavour. Carrying out this idea, wave meters were checked at the exposition free of charge by United States radio inspectors in charge of the Department®of Commerce exhibit. These inspectors examined applicants for radio operators' licences and granted them gratuity ously.
The exposition, which continued until March 11, affordisd the public an opportunity to learn many interesting things about the fast-developing radio industry. Many of the so-called mysteries of wireless telephony were explained by experts, numerous speed tests were made both amateur and professional operators competed for prizes. Motion pictures and lectures illustrated the function of vacuum tubes and amplifiers by which feeble waves are made to produce thunderous sound and inavdibly faint voices to grow vociferous and clear.
