GIRVAN, AYRSHIRE.—While a gale was blowing from the N.W., with a very rough sea on the morning of the 17th November, the smack Prosperity, of Carnarvon, was seen in the offing labouring against the wind, and shortly afterwards she showed a signal of distress. At 9.45 the Lifeboat, Sir Home Popham, was launched, crossed the bar, on which a heavy swell was encountered, and reached the vessel which was then embayed in Ardmillan Bay, about three miles south of Girvan, and had lost part of her sails. The master requested the Life-boat to stand by until his vessel had got a sufficient distance from the shore to enable him to weather Turnberry Point. This accordingly was done, the boat remaining by the smack for more than an hour..
