PENMON, ANGLESEY.—A schooner having been seen to run aground on the Dutchman's Bank during a N.W. wind and rough weather on the 20th August, the crew of the Life-boat were summoned, and the Life-boat, placed here temporarily while the station's boat was being altered and improved, launched. The schooner proved to be the Thomas, of Liverpool, bound for Stranraer with a cargo of salt. The Life-boatmen rendered assistance to the vessel, which leaked badly when she floated and two of the Life-boat crew were put on board to accompany her to Beaumaris..
