PLYMOUTH.—A report having been received, on the llth March, that a vessel was dragging her anchors in Batten Bay and required assistance, the Life-boat Escape put off at 8.15 A.M., during a gale from the "W. and a high sea, and found the Norwegian barque Souvenir, laden with maize, from Buenos Ayres, very near the shore and occasionally striking. Her main mast was soon afterwards cut away, and, in falling, carried the mizen mast with it, and as the vessel seemed to be in great danger, the Life-boat remained by her until 9.30, when, at the request of the master, the mate was brought ashore to obtain the services of steam-tugs to tow the ship off. The Life-boat was taken back to her station by the steam-tug Deerhound, arriving at 10.30 A.M..
