JUST ONE CLOCK TICK
 REGULATES ALL TINIE

WASHINGTON, Jan. 14-Special to Yuma Daily Examiner by J. E. Jones' Every day at noon the correct time is sent out over all the telegraph wires in the country from the National O. servatory at Washington and the tele- graph instruments click and the great time halls fall upon the instant of nOoE day. The recent development of wire less has been utilized and at ten O. clock each night the mechanism at tie National Observatory cells the time 70 wireless stations and 70 shIps at sea. It vas little more than year ago that the receiving apparatus a. the great government wireless station at Arlinb-
 on. 1cr, Ss the Potomac at Washington n.ard a regrJar click, "E ;I. IL was IS regular as clock work and they com pared it with the beats of the Washing ton clock. In fact the clicking of the instrument was the registering of the move of the pendulum of clock, and that clock was 31S1 miles away and a great sea heaved between. The men at Arlington were listening to the tick of a clock at Paris. On that November night was marked the project of prac- tical instantaneous transmission of standard time. The test conducted between the National Observatory and the Paris Observatory has demOnstrat ed that signals are transmitted by wire less at a speed of approximately 175- 900 miles a second, or slightly slower than the speed of light. The clicking of the instrument on that November night a year ago was tangible evidence of the successful hooking up of a part of a project, worldwide in it's con ception, for sending the time to naviga- tors, explorers, surveyors, and jewel CTS wherever they may happen to be upon the surface of the globe. If ever another Stanley is lost in Africa, O.. another Scott stranded on the Antartic Continent, and he has included a wire less in his luggage by stringing it up tree or the South Pole perhaps he can get into communication with the out side world. No one dares to say that this is an impossibility.
 On October 25 last year the dele gates of the International Conference of the Hour, including the United States and 23 other countries, as sembled at Paris and signed an agree ment to be presented for ratification to the countries represented for the establishment of a standard time for the world and the naming of Paris a point from which Greenwich time was to be distributed. Some months ago the official clocks of Paris, by pre- arrangement, were stopped and reset at Greewich time.
 The signals were to be sent out by means of the radio apparatus on the Eiffel Tower every day at 10 A. M. and at midnight. Other stations were to assist in the distribution, other hours, which will not interfere having been selected for signals from these. For instance, the Naval Observatory at Washington, the first, by the way, to send out time signals, does so at noon and at 10 P M. and hours which will not conflict, have been named for the observatories at Manila, Mogadascio, Somali Coast, Africa; San Fernando, Brazil; Timbuctoo, Africa; Nord- deich, Germany; Massonah, Africa and San Francisco. In this way the marines on all of the seven seas will be furnished with the correct time Of day in the.part of the world in which their bark may be cleaving the waves.
