FORMBY.—Two vessels being sighted in a very dangerous position on the Great Burbo Bank, having run aground in a fog, on the 21st March, the Life-boat John and Henrietta was launched at 8.15 A.M., and after a long pull reached the vessels and stood by them until they were out of danger. One of them, the barque Concurrent, of Ghristiania, timber laden for Liverpool, was towed off the bank; and the other, the schooner Waterlily, of Liverpool, bound for Euncorn with a cargo of clay, floated off without assistance..
