CAISTEE, NORFOLK.—At 4 a.m. on the 7th October, flares and rockets were seen in the direction of the Cross Sand, apparently fired from a steam vessel on the sand. The Caister No. 1 Life-boat Covent Garden was promptly launched, and in going over the Scroby Sand took several heavy seas and sprung her fore-mast. On reaching the Cross Sand the B.S. Speedwell, of Hull, bound for London with fish, was discovered stranded there in the midst of the breakers. Her crew had left her in two boats, and were just at the edge of the sand. The Life-boat sailed towards them, and the crew, consisting of thirteen men and one passenger, were taken into her..
