GREAT YARMOUTH.—Intelligence was received on the morning of the 27th December that the brig Countess of Zetland, of Wells, was ashore on the beach. A strong S. by E. wind was blowing, and a heavy sea running at the time. The Abraham Thomas Life-boat was immediately launched, and proceeded to the vessel, which had gone ashore north of the Britannia Pier. A line having been passed to the brig by the rocket apparatus, the Life-boat was hauled alongside, and the vessel's crew of 7 men were taken into the boat and brought safely ashore..
