On the 15th Nov. the surf Life-boat, the Boys, assisted by a steamer, saved the schooner Mediateur, of Nantes, and her crew of 6 men, from a dangerous position near the North Star Battery, Great Yar- mouth. The vessel was damaged in the stern, and was riding so close in-shore, with all her chain out, that on the turn of the tide she would in all probability have been driven on to the beach, had she not been thus rescued.
