Yesterday Capt. Broadhurst, in the schooner Fidelity, from Martinico for Brunswick, was chased in here by a large white-bottomed sloop, with a square-sail and standing top-sail, supposed to be a tender, as she appeared to be full of men; she followed the schooner on to the bar, till it was thought she struck; ー being low water, and the bar rough, she wore round and stood out, and has been beating off and on ever since.
