WALMER.—At about 3.15 A.M. on the 28th June, it was reported that a ship was ashore on the Goodwin Sands. The Life-boat Centurion accordingly proceeded to the inner part of the South Sand Head, and found the ship Colombo, of Greenock, ashore there. She was bound from Bassein, India, to Bremen, with a cargo of rice; her crew consisted of 24 men, and the master's wife and child were also on board. The captain engaged the services of the Life-boat men and others to lighten the ship. After throwing over about 250 tons of cargo, they succeeded in removing her from her perilous position, and took her into the Downs. There was a fresh W.S.W. wind at the time and the weather was hazy..
