   Unable to swim, two brothers, 27 and 25 years old, drowned at 10:10 a.m. Sunday in Puddingstone reservoir when the motorboat carrying their father and four other occupants overturned.
   Bodies of Julius Ernest Haase Hr., 25, and his brother, Frank, 27, of 1955 South Charlotte street, Rosemead, were recovered in 35 feet of water by F. A. Pollard, reservoir attendant, wit the assistance of the survivors and others, and removed to Todd's Memorial chapel in Pomona for transfer to Forest pending completion of the investigation.
  Julius Haase, father of the drowned men, and two other boat occupants, Jack R. Herron, 25, of 2505 Gladys avenue, Wilmar, and Franklin C. Lochi, 25, of East Ramona avenue told San Dimas sheriff's officers they tried to rescue the Haase brothers, but the non-swimmers broke free from their group and sank.
   James Franco, 30, of 1129 Mariposa street, San Francisco and Dave Oden, 31, of 2322 Falling Leaf street, Wilmar, the other occupants of the boat, were picked up in boats which came to the rescue.
   County lifeguards were summoned from Hermosa Beach, but the bodies were recovered before they were able to set out for San Dimas.
   Julius Ernest Hesse's body was recovered first, officers said, and taken to the north shore, where resuscitation equipment from the Baldwin Fire Engine company, with Fire Chief Paul C. Clark in charge went to work at 11;21 a.m.  The Attending physician pronounced the younger brother dead at 12:45 p.m..
   By that time, the other brother's body had been recovered and hope for his resuscitation was abandoned.
   Frank Haase had been operating the boat, a 19 1/2 foot inboard speed boat and turned the rudder over to Franco, when the boat overturned and sank 200 yards north of the south shore, according to officials.
   Franco said the boat seemed to pause as if hung up on something before it overturned, but the elder Hause [sic] said Franco had been cutting and turning the overloaded boat, and these maneuvers caused the boat to upset.
   Officers said the survivors, suffering from shock and exposure, were taken home by friends.
