HILBRE ISLAND.—The Life-boat Admiral Briggs was launched at 1.9 P.M., on the26th March, an intimation having been received that a vessel was driving on to the rocks. The weather at the time was misty, a whole gale of wind was blowing from W.S.W., and there was a very heavy sea on. The vessel in question proved to be the flat Swift, and at the request of the master the Life-boat remained by, and ultimately helped to get her out of danger. The boat then went to three other flats, and found they were all right; arrangements were, however, made with the crews that they should show lights should they find they needed any help..
