This article was somewhat uncertain about the spelling of the featured singer's name. Most accounts state that the vocalist's name was "Dorothy Lutton".

Girl  Singing  110  Miles  Away  Listened  to  by  Vast  Audience  at  Chateau.


Gramophone  Orchestra  Selections  Danced  to  at  the  Radio  Station  Here.

By  Canadian  Associated  Press.
MONTREAL, May 20. -- A concert staged in the top floor of the Marconi building on William street, this city, was given tonight for the benefit of an audience assembled over 100 miles away in the Chateau Laurier, Ottawa. Later in the evening a message was received from the Chateau that the concert had been heard, and congratulations were offered. The occasion was an experiment in wireless telephony, which has not so far been demonstrated in a public way over distances of more than a mile or so. By reason of an amplifyer at the Ottawa end, more of the concert could be heard in Ottawa than in Montreal.

    "Hello, Ottawa--Hello Montreal"--and the first radio-telephone conversation ever carried on in Canada was commenced. A few minutes of conversation and then, through the night air, came the sweet notes of "Believe Me, If All Those Endearing Young Charms," to be followed some minutes later by the voice of John McCormick, singing "Dear Old Pal of Mine."
    The members of the large audience in the comfortable ball room of the Chateau Laurier sat in amazement, realizing that they were listening to one of those wonders that had been so much talked about but seldom demonstrated. The sweet voice they heard so plainly was that of Miss Lutten, singing into a radio-telephone instrument in Montreal. Every inflection of her beautiful voice and every word was audible to the Chateau audience, yet no wires connected the two points, 110 miles apart.

A  Complete  Success.

    This experiment, the first ever carried on in Canada when messages were received and replies given, was in connection with the lecture of Dr. A. S. Eve, F.R.S.C., before the Royal Society of Canada last night. Since Tuesday the officers of the Naval Radio Service and engineers of the Canadian Marconi Company have been making ready for the test. Weather conditions were reported as decidedly unfavorable during the evening, but the entire programme was carried out without a hitch, and congratulations were sent backwards and forwards by all concerned.

Three  Stations  Operating.

    The whole programme had been arranged beforehand. The station at the Marconi plant in Montreal and that of the Naval Radio Service in Ottawa were the main stations, with a receiving station at the Chateau Laurier. Here a huge amplifier was installed so that the entire audience was enabled to hear the programme between the two main stations. This is the first time that such an elaborate programme has been attempted, and one of the longest distances over which wireless telephone conversation has been attempted.

Could  Dance  to  It.

    The Journal reporter, through the kindness of the naval officers, was permitted to "listen in" on the whole affair at the Naval Radio Station on Wellington street. Sharp at 9.44 both stations got in touch, and the notes of "Dear Old Pal of Mine," played in Montreal on a phonograph, could be heard clearly and distinctly. Next the latest one step was put on in Montreal, and the different instruments in the orchestra could be clearly distinguished. So clear, in fact, that a couple at this end would have had no trouble dancing to it. In fact, some newspapermen did. Then the Montreal operator read the sealed message that President Dr. R. F. Ruttan wished him to deliver to the Royal Society of Canada.

Absolutely  Clear.

    There was a short pause, then clearly and distinctly, the beautiful words and music of "Believe Me If All Those Endearing Young Charms" were heard as sung by Miss Lutten in Montreal. The members of the audience in the Chateau were amazed, and the little group in the wireless station elated at the success of their experiment. By request, Miss Lutton sang a second song.

Wireless  Sparks  "Butt  In."

    It was then Ottawa's turn to speak to Montreal. The Ottawa operator explained to the Chateau audience something of the experiment, and then Mr. E. Hawken, an officer of the Marine Department, sang "Annie Laurie." Deafening applause greeted this at the Chateau and the second verse was requested. Then, several dance records were played at the Ottawa station. Later in the evening an attempt was made to get The Journal representative in touch with a Montreal newspaper, but several large radio stations were working and it was difficult to make a connection.

Operators  in  Charge.

    Mr. Arthur S. Runciman, radio engineer for the Marconi Company, was responsible for the success of the Ottawa end of the venture. The Montreal operator was Mr. J. O. G. Cann, chief engineer for the Marconi Company. At the Naval Radio Station, assisting Mr. Runciman, were Mr. Manson, chief examining officer for the radio service, and Mr. J. H. T. Arial, radio engineer.
    Mr. E. Hawken, officer commanding the Marine Department, and Mrs. Hawken were also present. At the receiving station in the Chateau Laurier were Commander C. P. Edwards, director of Canadian Radio Service, and Lieut. J. H. T. Thompson, assistant.

At  the  Chateau.

    During the experiment, before a vast audience at the Chateau, Dr. A. S. Eve, F.R.C.S., of McGill University, delivered an illustrated lecture on "Some Inventions of the Great War," and conducted a series of remarkable scientific experiments, the outstanding feature of which was the actual hearing by the audience of the singing of Miss Lutten.

Dr.  Eve  Pleased.

    "Strays," the nature of which science has so far been unable to determine accurately, necessitated an exceptional amount of amplification when Miss Lutten sang, stated Dr. Eve at the conclusion of the demonstration. Atmospherical disturbances occasioned by street cars, and "everything passing through space" was very pronounced last night, Dr. Eve said. Although conditions were adverse to a most successful experiment, Dr. Eve expressed himself as thoroughly satisfied with the result.

Explains  Action.

    Dr. Eve illustrated and explained the methods invented during the progress of the war for the detection of submarines, and the steering of ships from the shore by means of electricity. He explained in detail the principles upon which wireless telephony is operated. Wireless telegraphic messages were received from several of the long distance stations, in one instance over 1,000 miles from Ottawa, and the construction of the "Magnavox," which make possible the hearing of telephonic conversations by a large audience, was explained.
    The successfully conducted experiments were heartily applauded. Dr. Eve proved himself an interesting speaker, and handled his subjects in a way easily comprehended by the ordinary man of limited scientific attainment.
