HEAR  MUSIC  BY  WIRELESS.

    A wireless operator of the North German Lloyd liner George Washington, which sailed Saturday for Bremen, heard when some distance off the Long Island coast a whistle, an ordinary plain, human whistle, emitted by a man in the Telefunken station at Sayville, L. I.
    The whistle was long and was distinctly heard aboard the ship named for the father of his country on his natal day. It was preliminary to music from a phonograph placed close to a telephone receiver in the Sayville station. The tune the phonograph ground out was "The Star Spangled Banner," and the man at the George Washington end of the wireless line heard the tune clearly. At the same time the wireless Telefunken station on the tower of 111 Broadway also heard the music. The operator there said that it sounded almost as if the band were in the next room. Naturally, nobody could hear anything except the men aboard ship and at the Manhattan end of the line who had receivers glued to their ears.
    Director Bredow, of the North German Lloyd Line, a passenger on the George Washington, seemed to be greatly pleased with the success of the first test of the wireless telephone. He sent this message by wireless to The Sun by way of Sayville:
    "First test with Count Arcos wireless telephone very satisfactory. On board steamship George Washington we heard at a great distance 'The Star Spangled Banner' played by phonograph installed at the Telefunken station at Sayville, L. I."
    It was said at the Broadway office of the Telefunken Co. that there had been some experimenting by wireless telephone for several weeks, and that the company had not expected to make the results of the experiments public until later.
    The message from Director Bredow inspired the official in charge at the office to say that the ultimate aim of the company was to utilize the wireless telephone commercially and that Director Bredow was right in saying that the first important test of the telephone had been satisfactory.
