 WIRES OR "CENTRAL" " Conversations Between San Francisco and Mare Island Navy Yard Already
 Carried on

] San Francisco, Feb. 13.-"'Hello-ie
 this Honolulu? How are you? This
 is San Francisco" Some such greet
 ing over the broad Pacific by wireless
 telephone will be indulged in before 1915 if the experiments now being con-
 ducted by Lieutenant E. H. Dodd, U.
 S. N, at Mare Island, continue to be
 as successful as they have been in the
 last two weeks.
 If the navy wireless department
 consented, you could soon go to the
 wireles telephone on. the roof of the
 Fairmont hotel and converse with a
 friend at Mare Island in ordinary
 ether. You would need no telephone book, no wires and no central Just i go to the telephone, say Hello, Mare Island," and tele-ta,k
 Lieutenant Dodd, who has charge ! of all wireless stations on the Pacific coast, has been making tests this month with wireless instrument
 that promises to revo'utiontze the en- tire sphere of long distance talking. l Transcontinental and oceanic conver-
 sation are considered practical possi- biIities of the invention.
 Cape Blanco, 400 miles by air line up the coast, in Oregon, has heard a man | ta king through the Mare Island wire less telephone. The F'arallones com | plained that Mare Island talked too i loud, the operator declaring that he 2 ephone, but also the voices Of others in the sending room. Thus far the tel ! ephone has been install ed only at the i naval station and on the F'afrmont roof, but any wireless telegraph sta ton can receive the telephone mes- sages without special equipment The
 Fairmont telephone has been heard miles at sea by government vessels and by steamships, and many wireless i operators have been mystified by strange voices that seemed to come from nowhere.
 Lieutenant Dodd will recommend to the Navy department at Washington that seven wireless telephones be i'm
 stalled on this coast to continue hts
 experiments. Two will be installed on
 board cruisers and five at wireless sta
 tions. The stations which he will sug-
 gest are Goat Island, Mare Island, the
 FaralIon Is ands, Table Bluff and | Point Arguello.
 The attention of the. government was first called to the invention when experiments were being made with 1t at the aviation meet at Tanforan. When the private demonstrations
 were being made Lieutenant Dodd
 became interested After the telephone was in working order at the Fairmout the navy officer asked for a demon
 stration a month ago. The wireless telephone operator talked to the wire | less telegraph operator at Mare Island and was plain heard. A peculiar feature of the new telephone is that any wireless telegraph station can listen in'' to the conversation, but cannot, of course, talk back Lieu tenant Dodd caused a machine to be installed at Mare Island and a talk
 fest'' was easily indulged in between this city and the naval station.
 The Mare Island operator then test ed the distance power of the instru- ment. Government regu ations require a wireless conversation of 20 miles to continue successfully a, half hour.
 This requirement. was exceeded many times The wireless voice was heard 52 miles away at Farallones. Table Bluff, ITO miles distant, in Humboldt county, responded by wireless tele- graph to the wierd call. Point Ar gueIlo 262 miles south, and Point Loma, off San Diego, heard the opera tor talking at Mare Island. Ships 600 miles at sea have been startled by the unknown voice out of the wilderness of air.
