WHITBY.—At about 10 A.M., on the 28th of January, five fishing cobles, which had left the harbour about six hours previously, were observed to be returning, the sea having risen considerably. As crossing the bar was, under the circumstances, a very dangerous operation to the boats, the No. 2 Life-boat, the Harriott Forteath, was launched, supplied the crews of the cobles with life-belts, and remained by the boats until they got communication -with the shore, all being safely beached by noon..
