Reynolds  Plans  Wireless  Study;  Outfit  on  Way
____________

    Dr. W. D. Reynolds, 729 South Prospect street, will soon install the first wireless telephone in the Pikes Peak region. The apparatus is now enroute to this city and as soon as the government ban on wireless operations is removed Dr. Reynolds will start a series of experiments. He plans a trip to Pikes Peak, from which point he will talk to the station at his home. He has a large wireless set at his former home in Minneapolis and he is bringing it to the city, having recently moved here from the Minnesota metropolis.
    Dr. Reynolds has formed a wireless experimenters class, which will meet alternate Friday evenings at the All Souls church, corner Dale and Tejon streets. The club meets tonight and the public is invited, with a special invitation to boy and girl scouts and service men who have had wireless experience.

MARSEILLAISE'S  MARTIAL  NOTES  BRIDGE  GAP  FROM  DENVER  HERE  THRU  ETHER  BY  RADIO  PHONE

    Not, "Send us help, quick!" but the melodious strains of a popular song has been the first "message" to be sent over the wireless telephone which the United States forestry service has set up in Denver to try out.
    The foresters last night connected up with the wireless station at the home of Dr. William D. Reynolds, 729 South Prospect street. Dr. Reynolds and Richard R. Roby of the Colorado Springs High School Amateur Wireless association, then received a phonograph record, which was heard with startling clearness. A number of other persons also witnessed the experiment at this end.
    This is the first time that a wireless telephone message has been sent anywhere near this distance in the west. The experiment is one which on account of the high altitude and other features will doubtless attract attention thruout the country.
    It was a complete success, Dr. Reynolds said last night. The operators talked with each other freely and a number of different kinds of records were sent, in order that it might be determined which tones carried best.
    "I think this is a good one," said the operator in Denver. "I am going to put on the phonograph, which is about 15 inches away from the instrument, the French national air. Tell me if you hear it plainly."
    The next moment the strains of the "Marseillaise" were heard clear as a bell. It was a remarkably good record which was used and the tones of each instrument could be heard plainly. This proved to be the clearest of all of the records used in the experiment
