HOPE COVE.—Intelligence having been received that a vessel was ashore at Sewer Mill Sands on the 18th January, the Alexandra Life-boat was launched at 8.30 A.M., and proceeded to her assistance during a strong S.E. wind and a heavy sea. She proved to be the ship Halloween, of and for London, from Foochow, witha cargo of tea. Nineteen of her crew were taken into the Life-boat from the foretop and rigging, where they had been during the whole of the previous night, and safely landed. Three others had previously attempted to swim to the shore with a line, but each of them let it slip; two of them succeeded in reaching the shore, but the third man was unfortunately drowned..
