GROOMSPORT, Co. DOWN.—The Lifeboat George Pooley was launched at 5.40 A.M. on the 21st February, while a gale was blowing from E.S.E., and proceeded to the assistance of the schooner Caledonia, which, while on a voyage from Ayr to Wexford, with a cargo of coal, stranded on Briggs reef. As the vessel was filling with water, her crew of five men took to the Life-boat and were safely landed at 6.45..
