WEXFORD.— A sudden gale sprung up from the E.N.E., accompanied by snow-showers and a heavy sea, on the morning of the 25th March, and the schooner Perseverance, of Wexford, homeward bound in ballast from Dublin, stranded on Raven Point. The Lifeboat James Stevens No. 15 put off at 9 o'clock and stood by her until she floated and succeeded in getting into the harbour..
