RADIO PROGRESS IN U.S.

I — AID TO OCEAN TRAVEL. tFrom Our Special Correspondent.) SAX FRANCISCO, July 20. The use of the radio compass as a marine asset, not alone in ship communication but in position finding for vessels, 'is a valued acquisition of the United States Government, and one of the most important modern developments perfected to safeguard ocean travel both ;bj liners and merchantmen. Within a , comparatively brief period of time no I less than twenty ships have been saved J from destruction by its instrumentality !as a result of the alertness of naval ■ compass stations. j On the Atlantic coast radio compass stations extend from Portland, Maine, to ! Dry Tortujras, and on the Pacific coast i from I'.ehring !Sea ti> San Diego in Sou-, . tliern California. The cost to the United! , States Government has been estimated lat a million dollars, and the saving in ■ ships effected by these tiny isolated . branches of silent Federal service runs ; into many millions of dollars. The ship- j pinjf losses avoided by them has been! 'Variously estimated at from 25,000,000 i !to 50.000,000. I : Po accurate is the working of this new development of marine safety that a steamship captain whose vessel is so equipped is hard put for an alibi when , lie piles up his craft on a reef and turns a first-class craft into a subject for the salvage court.
