SKERRIES.—About 3 P.M. on the 16th April, the schooner Isabella, of Portmadoc, bound from London to Dundalk, was observed to part from her anchors and drive towards the rocks. A strong gale from the E.S.E. was blowing, and a heavy sea was breaking on the shore. In anticipation of this disaster, the crew of the Life-boat Laura Platt had been in readiness for somehours, and they now used every effort to get the Life-boat afloat as speedily as possible, aided by numerous helpers. It was a tedious and difficult operation, owing to the low tide. The boat was fairly afloat, however, by 3.15, and closed the vessel near enough to haul the crew on board, one at a time as opportunity served, by lowering themselves from the weather quarter, the Isabella all the time driving fast towards the rocks. By 4.80 the last of the 5 men who formed the crew was thus rescued by being hauled on board the Life-boat, and in a short time after they were landed their ship was daehed to pieces..
