HOLYHEAD.—The three-masted brigantine Emerald, of Liverpool, was seen flying a signal of distress during a strong 8. gale and a rough sea on the morning of the 13th December. The Life-boat Thomas' Fielden was launched to the assistance of the vessel, which was apparently ashore near Clipera Point, but before she reached her she had slipped her anchor, and had run to leeward in the bay. A steam tug got a line on board her, and part of the Life-boat's crew assisted in hauling the hawser on board; two of the Life-boatmen remained to assist in mooring the vessel. The Life-boat then proceeded to the schooner Ann, of Liverpool, which was showing a signal of distress outside the end of the breakwater, and brought the vessel, with her crew of four men, safely into the old harbour..
