HARWICH.—On the 2nd December, the Life-boat Spring-well proceeded out about 10.30 P.M., in response to signals flredfrom the Sunk light-ship. On arriving at that light-ship, it was stated that signals had been made from the Kentish Knock. The boat then proceeded to the Long Sand, and there found the Swedish barque Jacob Langstrum a total wreck on the sands. She had a crew of 8 men on board, who were rescued by the Life-boat with some difficulty on account of the heavy sea, the wind blowing strong from the N.E. The boat remained in sight of the ship until daylight, when the steam-tug Harwich came up, the rescued crew were placed on board her, and the boat was towed back to her station, which was reached at noon..
