    "Please put that 'Turkey-in-the-Straw' record on again. Grandma wants to hear it again."
    Sounds like some family parlor conversation, doesn't it. But that was just one of the messages which came over the phone at wireless laboratory of Precision Equipment Co., 2437 Gilbert-av.
    For more than a year this company has been holding wireless concerts and making other experiments with the wireless telephone. Calls for special pieces were received from stations as far away as Dayton, O.
Breckel  In  Charge
    Harry F. Breckel, 1222 Homeside-av, is chief engineer in charge of the laboratory. He conducts concerts every Monday and Wednesday nights for the benefit of any station, amateur or otherwise, which wishes to listen in. Breckel served as a lieutenant in the navy on the armed yacht Corsair during the war.
    The wireless telephone still is in its infancy, but has passed the experimental stage and soon will prove more practical than even the wireless telegraph, according to John L. Gates, president of the company.
Development  Cited
    The wireless telephone, he says, has been developed to the point now where individual voices are easily recognizable at hundreds of miles distance. Telephone equipment is only a little more expensive than telegraph, and its simplicity of operation soon will give it widespread use, Gates believes.
    Regular semi-weekly concerts are given in a laboratory by means of a phonograph and player-piano. Special apparatus is used to collect sound waves from these instruments and transmit it to sending apparatus.
    Cards have been received by the company indicating their concerts have been heard at Palm Beach, Fla.; Ontario, Can.; Ottumwa, Ia., and eastern coast of Massachusetts.
Receiving  Set,  Too
    The laboratory also contains a receiving set which regularly "picks up" concerts and messages from New York City. On one occasion, according to Breckel, he succeeded in listening in on a concert on board ship well out into the Atlantic, and actually heard passengers of the ship calling for the steward.
    The laboratory is open to the public Mondays and Wednesdays from 8 to 10 p. m. when concerts are given.
