LOWESTOFT.—On the night of the 2nd November, 1861, the schooner Fly, of Whitby, was in a leaky state, and in danger of foundering near Lowestoft, in a heavy gale from the north. On her making signalsof distress, the life-boat of the NATIONAL LIFE-BOAT INSTITUTION, at Lowestoft, was launched through a tremendous surf, and proceeded to her assistance. Some of the life-boat's crew were placed on board, and succeeded in taking her safely into Lowestoft Harbour. The vessel and her crew of 4 men would probably have been lost but for this aid..
