PORTRUSH.—The brigantine Sunshine, of and from St. John, N.B., laden with timber, arrived off Coleraine Bar on the 4th July and anchored, waiting for a sufficient depth of water to enable her to cross the bar. On the 10th a gale from the N.E. commenced, with a heavy sea, and the vessel, which was riding very heavily and shipping seas fore and aft, parted her starboard anchor at about 1.30 the following morning, after drifting some distance. As she appeared to be in danger of stranding, the Life-boat, John Whitaker, put off to her aid at about 3 P.M., and rendered assistance in getting up the remaining anchor. The vessel was ultimately towed into Portrush by a steam-tug which bad arrived from Londonderry..
