lew Methods Employed by British Navy to Destroy Undersea Vessels Being Studied by Americans
HUGH DEPENDENCE WILL WE PLACED IN
 DREADNAUGHT TYPE
fig Guns Essential for Ef- fective Defense = Mines and Submarines Will Be Built on Large Scale

Washington, October 2.-The American ivy policy for the coming year, tenta- 'e plans for which recognize the sudden velopment of submarine warfare, with ovision for a large number of undersea bats, will be broadly affected by the Fitish admiraltys development of pro- amme of successful means for combat E the submarine peril.
 Confidential reports to the United States pn of from 50 to 70 German submarines the use of nets, submarine telephones, Pw types of mines and by covering the bmarine, are a valuable adjunct with fleet, believe now the high-speed mo- rboats, supplied with rapid-fire guns, e to fulfill the conviction of world wal experts that means would be found successfully circumvent undersea war re.
 Likewise, the reports have reaffirmed e faith of American experts in the all g-gun ship, the dreadnaught, as the fective fighting force of any navy. Increase Number of Dreadnaughts One Immediate development of this west lesson drawn from the European hr probably will be provision made for the new naval bill for continued addi- bns of the dreadnaught fleet, instead
 building submarines on the extensive ale desired by many. It is plain, however. that the devel- |ment of successful means of repelling bmarine warfare will not mean the bandonment of substantial additions to e submarine improved fleet. The new [val building budget probably will in- llde more than the usual number of bmersibles and they will all be of the Ew high-power speed, sea going cruiser be- carrying rapidfire guns, recently de- |loped in the naval gun factory.
 Naval officers realize that the remark le success of the German undersea boats eated a profound impression through 1t the country and was the cause of |ousing a powerful sentiment for the hiding of large number of subma- hes almost to the total exclusion of g-beamed battleships, on the theory that submersible had proved it's adequacy destroy fighting ship costing 10 times
 much.
 past Defense Depends on Big Guns Now that successful means of combat g the submarine have been developed strategists feel that the naval defense
 the coasts of the United States stil sts where they always have contended has-on the big-gun fleet. They feel O, that while the navy should be ade lately supplied with submersibles, the xt development in proof is to provide cans of repelling submarine caisson at cks as has been done in Europe by eel nets, and to carry out logica aggressive building policy for the bis bet along the lines laid down by tht ivy general board, which stands fol
 first-line dreadnaughts by 1920.
 Various means for developing defense sainst submarines are being tested ir American navy. All these experiments e of a most confidential character, bu is known that the best scientific experts
 the technical corps are working or ewer ideas in mines, nets and subma he telephones.
 Plans for the two new dreadnaught' lthorized by the last Congress include cans of defense against submarines hich probably are not known to any
 the European belligerents and. thu afting of smaller boats for the shallow hters of the Atlantic coast, adjacent t rge cities, whose harbors might pos bly be the targets of submarine invad s. Experiments constantly are beinf rried on. Obviously the nature of thest Ill not be disclosed by the navy depart ont.
 Naval experts consider that a mos tito fleet, such as Great Britain Ina! veloped might be created in the United ates.
