COURTOWN.—On the 19th November, the Life-boat Alfred and Ernest went off to the assistance of the s.s. Rainton, of Glasgow, which had grounded on the North end of the Glassgorman Bank during squally weather, the wind blowing from the W.N.W. The Life-boat took out a hawser, and towed the steamer's boat with a kedge anchor astern of the vessel, by which means she was got afloat and proceeded on her voyage..
