KIMERIDGE, DORSET.—A vessel was reported ashore on Kimeridge Ledge during a thick fog, a heavy ground sea, and a fresh S.W. wind, on the 26th June. The Life-boat Augustus Arkwright was launched at 9 P.M. and found the stranded vessel was the brigantine Lythemore, of Llanelly, bound from Cardiff for Southampton with a cargo of steam-coal. She was in no immediate danger, but the Life-boat, at the request of the captain, remained by her during the night, and on the following morning laid out an anchor, so as to enable her to be hauled into deep water when the tide served..
