перевидите пожалуйста The Case of the Very Strange Shipwreck In the records of Lloyd's of London is the case of the schooner Mermaid and her twenty-two men.Lloyd's has many strange stories in its huge files,but nothing quite like this one. It all began pleasantly enough on the morning of 16 October 1829,when the Mermaid slipped out of the bay at Sydney bound for Collier Bay,on the west coast of Australia.Aboard the ship were eighteen able seamen,three passengers,and Captain Samuel Nolbrow,at the wheel.Without realisting it,they were all starting a voyage that is probably unmatched in the history of the sea. On the fourth day out of Sydney,the captain turned the wheel over to the first mate.The crew lolled about the deck,for they had little to do now.The barometer gave no hint of what was to come.It looked like fair weather and smooth sailing,until shortly before two o'clock in the afternoon.Then the ship found herself becalmed.Think grey clouds scudded over the face of the sun Captain Nolbrow came on deck again-to find the barometer falling rapidly.Shortly before dark the calm ended with great gusts of wind that soon turned into a reging gale.The Mermaid fought for her life; for she was in the notorious Staits of Torres, a narrow channel that had claimed many a ship and many a crew
