KESSINGLAND.—On the 22nd December, the schooner Eliza, of Sunderland, and the sloop Firm, of London, were observed showing signals of distress on Benacre Point. The No. 2 Life-boat, the Grace and Lolly, of Broad Oak, was promptly launched, and succeeded in getting both vessels afloat, and in taking them safely into harbour. The first-named vessel carried a crew of 4 men, and the latter was manned by 6 men..
