To Resume Time Tests.

New York Times 100 years ago today, May 20, 1913:
Long Wireless Experiments Between Paris and Washington.
By Marconi Transatlantic Wireless Telegraph to The New York Times.
    PARIS, May 19.— Beginning next October, extensive wireless tests, lasting six months, will be resumed between Paris and Washington on lines similar to those of the tests carried out under the auspices of the Bureau of Longitude last March.
    A report on the tests already made by the French mission which visited Arlington was read to the Academy of Sciences to-day. According to it, despite unfavorable weather, important results were obtained. It was found possible to make frequent comparisons of time by the radiographic system, while on the night of March 28 Paris and Washington were able to converse. Attempts were also successfully made to photograph records of wireless signals.
    When the tests are resumed next Autumn the speed of Hertzian waves across the Atlantic will be determined. As at present calculated, the speed is equal to that of light.
    The report also says that as soon as various Colonial wireless stations are completed, around-the-world tests will be made, with the Eiffel Tower as the first transmitting station.
