PORTHOUSTOCK, CORNWALL.—At about 6 A.M., on the 23rd March, the Coxswain of the Life-boat Charlotte, waa informed that a vessel was firing signals of distress, having stranded on the Manacles rocks. A light wind wag then blowing from N.E., and the sea was moderate, but the weather was thick. The crew of the Life-boat were summoned, at about 6.30 the boat was launched, and on reaching the vessel found she was the barque O.B., of and from Fecamp, bound for the Newfoundland fishery, and laden with salt. Having slightly struck the reef known as the Outer Main Voices, she had anchored, and was lying in a most dangerous position, close to a mass of sunken rocks. The Waster refused any assistance from the Life-boat men, stating that all he required was a steam-tug, and ultimately one arrived, and with the help of some fishermen got a hawser on board, but it parted, and the tug, apparently not caring to face the danger of the rocks, did not make another attempt to effect communication with the vessel. Afterwards, the steamtug Eagle, of Falmonth, arrived, and the services of two of the Life-boat men having been asked for, to pilot her amongst therocks, they were pat on board; the hawser was attached to the barque, she was towed out of danger, and was taken into Falmonth harbour..
