HILBHE ISLAND.—Having received intelligence that a yawl was in a very dangerous position close to the rocks on the west side of the island, on the 24th June, the Life-boat Admiral Briggs was launched at 12.40 p.m., and proceeded through a rough sea to the spot where the yawl Conovium, of Beaumaris, was stranded. The master requested that some of the Life-boat men might board.
