The Padstow new Life-boat, the Arab, was launched at 2 P.M.on the 3rd September to the assistance of the schooner Maria, of Granville, bound for that port from Swansea, with a cargo of coal. The schooner had stranded on the Doom Bar, during a strong W. wind and a high sea. The Life-boat brought ashore two men who were on board, three others of the crew having previously landed in their own boat. The vessel afterwards sank and became a total wreck..
