CAISTER.—On the 6th November, flare lights having been seen in the direction of the Cross Sand, the No. 1 Life-boat Covent Garden proceeded out, and found the fishing-smack Mystery, of Great Yar- mouth, just off the sand. She was partly dismantled, and had been abandoned by her crew. The Life-boat men boarded her, sot sail, and took her into Yarmouth Eoads, where she was anchored until the following morning. At daylight a steam-tug was engaged, and towed her into Yarmouth Harbour. It was subsequently ascertained that her crew had got on board another fishing-smack. The wind was blowing strongly from the N. at the time, accompanied by squalls, and the sea was very heavy on the sand..
