Norman Read of Crescent City, California, is writing about Pearl Harbor and asks about the Japanese two-man submarines that were launched in the attack on Dec. 7, 1941. In the 1960s, more than 20 years after the attack, one of the midget subs was discovered by Navy divers who were conducting test dives near the harbor entrance. Following three days of salvage, the World War II relic was lashed to the side of a Navy vessel and transported to Waipo Point, Oahu. After months of intensive restoration, the sub was returned home for display at the Japanese Naval Academy in Etajima, Japan. Of the four other two-man subs launched on December 7, one was beached, two were sunk and one is presumed lost in action.Cameron Baker of Springfield, Ohio, wants to know if there's a Web site for the Mariner's Museum in Newport News, Virginia.

She wants to know if it was found. I'll have to contact my main man: Pat Smith, California Wreck Divers shipwreck expert. When he wrote his book, Shipwrecks of Southern California (Menasha Press, 1989), the _< I>had yet to be discovered.

Paul Jackson of Crofton, Maryland, who owns and operates In-Depth Contractors, has helped lifeguard Peter Leo and his friend Earl Young in their ongoing salvage efforts on what is believed to be the San Miguel el Arcangel. Jackson found 50 coins, mostly four and eight denomination silver reales dated 1654 to 1658. He says gold was scarce except for a few escudos and some finger bars with King Philip's stamp on them. Daggers, pistols, musket balls, cannons and other artifacts have also been salvaged. A settlement has been made with Florida officials for everything found on the wreck, which is scattered on the bottom in only 15 feet of water.Glen Powell of Butler, Pennsylvania, sends this question: Has anyone discovered the whereabouts of the English sloop Ontario that sank in 1783?

There was no mention of oil slicks on the beach, but for weeks locals said they saw a 'huge fish' and were afraid to go out in their boats. Rumors persist that a German man became rich selling diesel fuel to German subs on the Sixola River. Please help me sleuth this piece of history. There was a U.S. Navy base at Bahia Azul during WWII, and rumors prevail that a U.S. submarine was accidentally sunk in that area by friendly fire. I searched through a book, U.S. Submarine Attacks During WWII by John Alden (Naval Institute Press, Annapolis, MD) but couldn't find a clue on this sinking. I'm sending you the address of U-boat expert Harry Cooper of Hernando, Florida, who might be able to shed more light on this matter. _Send your wreck questions to Ellsworth Boyd, 1120 Bernoudy Road, White Hall, MD 21161.
