Impossible to Tow Stricken Craft to Shallow Water and Rescuers Are Forced to Send for Derrick
VESSEL FOUND AT DEPTH OF 300 FEET
 BY RESCUE BOATS
Believed the Ships Plates Sprung by Water Pres sure and Entire Crew of 2l Have Perished

Honolulu, March 26.-The Ameri- can submarine F-t, lost since yester- day morning off Honolulu harbor, was located late today. Heroic efforts were being made tonight to raise the stricken craft, but after having been submerged for more than 90 hours it was regarded as doubtful whether any of her crew of 2l men remained alive.
 To lift tho little vessel to the surface. fl was found necessary to send to the Pearl rarbor naval station for der rick and crane. This involved much loss of time and il was thought the fate of the crew might not be determined until daylight
 Rescue vessels dragging the ocean bed with srapplng hooks ehanced upon tho stricken craft at depth of DO feet. Making fast to the F-i the naval tug Navajo and the steamer Makaala began 10 tow thelr find-they were not certain that if was the submarine they had hoolIed-towards shallow water Quanti- ties of oil came to the surface, proof that 1t really was the lost vessel Soon afterward a submarine marker buoy. dis covered far below the water. removed all doubt that the Fl had been found.
 May Have Been Signal
 Just when the marker buoy had been released by the disabled ooat there was no means of determning If the signal was given after the erappliug hooks of the rescue vessels took hold then the crew or at least some of them, still were alive,
 For more than an hour the tug and 1 tre stcpuer struggled wit ther un- fwfeidiy burden. soon afterwdrds 1t be- came apparent that it would be impossi- ble to tow the submarine near enough to shore to bring her to the surface and a hurry call was sent Co the naval station for a wreclSing ship.
 Naval authorities admitted tonight they had given up hope for the F4s crew. However. resuscitatng apparatus had been dispatched to the scene and every effort will be made to develop any spark of life that may remain The general opinion is that the vessels plates were sprung through the immense pressure of the water at Il depth of 50 fathoms and that the two officers and 10 enlisted men above listed have perished.
 Vessels in the vicinity equipped with submarine signal apparatus continued to send out signals, but no answers came.
 Washington, March 2s.--Rear Admiral Moore at Honolulu cabled the navy de- partment late tonight that the missing submarine F-4. had been located in 50 fathoms of water. He gave no details.
 Hope for the lives of the 21 men on board the submarine virtually was aban- doned by naval officers here on receipt of this news The F-4 was designed to re- sist water pressure at a depth of approx imately 50 fathoms. or BOO feet. but it for her to remain at such a depth for any length of time with safety
 Records show that when the Fl. boat of the same type. operated on her trial trip for just 10 minutes at a depth of oS3 feet, her hull took In water.
 Faint encoura cement was found by of ficials in a suggestion that while the F-4 had been missing since she started on an underwater cruise yesterday morning. 1t was possible that she had been at the great depth at which she was located only a short time This seemed improbable. however as the long absence of tho boat and her failure to signal apparently made it certain that she met with some acci- dent which carried her to the bottom a few hours after going below the water.
 Tremendous Water Pressure
 Naval construction experts agree that the tremendous pressure of the water at any depth below 50 or 60 feet offers a serious handicap to any effort to provide safe exit from stinken submarine.
 The stay of a submarine below water is
