Gibraltar Talks with Washington.

New York Times 100 years ago today, March 13, 1913:
By Marconi Transatlantic Wireless Telegraph to The New York Times.
    LONDON, Thursday, March 13.— The Gibraltar correspondent of The Daily News says that the United States scout cruiser Salem left that port yesterday afternoon for home on the conclusion of a special cruise for carrying out important experiments in improved wireless telegraphy.
    Transmission was effected over 2,000 miles, while night communications between Washington and Gibraltar were kept up. The results were highly satisfactory.

Special to The New York Times.
    WASHINGTON, March 12.— The scout cruiser Salem left Gibraltar to-day for Hampton Roads. On her return voyage the Salem will test wireless communication with the Naval Radio station at Arlington as she did on the voyage from Hampton Roads to Gibraltar. While at Gibraltar the wireless experts of the Salem were permitted to use the British station for special experiments.
    The tests on the way across to Gibraltar proved that in the day time dispatches could be received continuously by the Salem's apparatus from the powerful station at Arlington up to a distance of 2,400 miles. Arlington was able to hear the Salem in the day time up to a distance of 3,300 miles. At night, when the atmospheric conditions are especially favorable for the transmission of wireless messages, communication was maintained easily at much greater distance.
    The navy experts regard the tests of the Arlington station and the Salem's plant as most successful. No definite conclusions in regard to the tests will be made public until after the daily records taken at Arlington and on the Salem can be compared.
