WESTON-SUPER-MARE. — As the S.S. Welsh Prince, of Newport, was leaving the pier at Weston-Super-Mare for Bristol, at 6.30 on the evening of the 22nd September, with upwards of forty passengers on board, and a crew of six men, a hawser by some means got foul of her propeller, and she began to drift into Sand Bay. A strong wind was blowing from the N.W. at the time, accompanied by a rough sea. She whistled for assistance; hoisted her colours, and then let go her anchor; but this not holding, she drove ashore amongst the rocks. The Life-boat William James Holt was launched to her assistance, and forty of the passengers were safely landed in the boat, which made two trips to the stranded steamer.
