Concert  Given  at  Fitzsimons  Hospital  Heard  in  Oil  Fields  of  Wyoming  and  Voice  of  Speaker  Picked  Up  in  Wisconsin.

(By  W.  H.  GRATTAN.)
    A concert heard simultaneously by bed-ridden patients at the Fitzsimons hospital and by 200 "listeners in" at stations as far distant as Montana and Wisconsin--
    Words that lifted by wireless telephony over the lofty crags of the Rockies and down to the plains for hundreds of miles, telling of a dance to be given in Denver.

    Sick in bed in a ward at the hospital, W. L. Winners talked over an ordinary telephone, his words were caught in a wireless telephone apparatus ten blocks distant and flung over a territory embracing several states.
    Experiments such as these, science crowding a field once held the fief of pure fantasy, were tried successfully Thursday night thru the use of equipment recently installed at the big government hospital at Aurora.
    It is said to have been the first time that land and wireless telephone systems were yoked up in the Rocky mountain region.
    Over the snow-clad heights sped rapidly as thought the words spoken by Winners and the beguiling tunes of up-to-the-minute jazz. Encores were demanded from the Wyoming ranch country on "Whispering" and "Cuban Moon."
    W. A. Berky, who, with Winners, is an instructor in wireless telephony at the government hospital, played on the saxophone. His selection was "Moaning Saxophone Rag."
    And far out in the mining country in Montana and the distant oil fields the music could be heard so clearly that listeners, "catching partners," could dance to the melodies.
    "Any amateur with a wireless telegraph receiving instrument could hear the concert and Winners' conversation," said Mr. Berky Friday. "I know one man with an apparatus costing only between $5 and $10, but he could 'listen in' as well as many with far more costly equipment.
    "Winners' illness was what gave us the idea for hooking up land and wireless telephones. He is an expert on wireless telephony and formerly was a first lieutenant in the army aviation signal corps. We wanted to make some arrangements for a dance that is to be given by wireless telephone at the Manual Training high school in Denver.
    "He talked into the ordinary telephone by his bed and I had charge of the apparatus at the wireless telephone station. The call went out first: 9 a. m. d. Hathaway. This was to catch the man who was to conduct the conversation for the high school. He heard Winners' words regarding preparation for the dance, the date for which has not been set. So clearly is music transmitted by the wireless telephone that a dance is entirely feasible, particularly thru use of an amplifier.
    "Hathaway, having no wireless telephone sender, replied in wireless telegraph code.
    "Then came the concert, which we are giving every Tuesday, Thursday and Sunday evening. We have had responses showing that the music is heard in the mining districts of Montana and the oil fields of Wyoming. Also we have had replies from a station in Wisconsin. Most of our selections are played on the phonograph but sometimes we use a saxophone. The saxophone music seems to carry better than that of any other instrument.
    "These experiments are being made in the belief that eventually wireless telephones will supersede all telegraph communications, that all the western country will be hooked up with apparatus that will permit the sending and receiving of the spoken word without wires."
    An appeal was sent out by the wireless telephone Thursday night for more phonograph records, Mr. Berky said. At each concert an effort is made to play different records. So all who desire to aid in the astonishing experiments have an opportunity to do so by contributing records.
    Mr. Berky gained his experience in wireless telephony while a radio electrician in the navy during the war.
