CAISTER, NORFOLK.—Flares in the direction of the "Scroby Elbow" Sand were seen by men on the look out in foggy weather on the morning of the 21st January, and they at once summoned the crew of the Life-boat Covent Garden. At 7 o'clock the boat was launched and on nearing the sands the schooner Bertha, of Yarmouth, was observed just floating off with the rising tide. Her crew had deserted their vessel and were seen in their boat alongside of and taking refuge on board the St. Nicholas Light-Vessel. With the assistance of steam-tugs the schooner, which had lost her rudder and had about three feet of water in her hold, was taken into Yarmouth Harbour..
