The Panda sailed from the Havana on the night of the 20th of August; and upon passing the Moro Castle, she was hailed, and asked, "where bound?" She replied, St. Thomas. The schooner now steered through the Bahama channel, on the usual route towards the coast of Guinea; a man was constantly kept at the mast head, on the lookout; they spoke a corvette, and on the morning of the 20th Sept., before light, and during the second mate's watch, a brig was discovered heading to the southward. Capt. Gilbert was asleep at the time, but got up shortly after she was seen, and ordered the Panda to go about and stand for the brig. A consultation was held between the captain, mate and carpenter, when the latter proposed to board her, and if she had any specie to rob her, confine the men below, and burn her. This proposition was instantly acceded to, and a musket was fired to make her heave to. This vessel was the American brig Mexican, Capt. Butman. She had left the pleasant harbor of Salem, Mass., on the last Wednesday of August, and was quietly pursuing her voyage towards Rio Janeiro. Nothing remarkable had happened on board, says Captain B., until half past two o'clock, in the morning of September 20th, in lat. 38, 0, N., lon. 24, 30, W. The attention of the watch on deck was forcibly arrested by the appearance of a vessel which passed across our stern about half a mile from us. At 4 A.M. saw her again passing across our bow, so near that we could perceive that it was a schooner with a fore top sail and top gallant sail. As it was somewhat dark she was soon out of sight. At daylight saw her about five miles off the weather quarter standing on the wind on the same tack we were on, the wind was light at SSW and we were standing about S.E. At 8 A.M. she was about two miles right to windward of us; could perceive a large number of men upon her deck, and one man on the fore top gallant yard looking out; was very suspicious of her, but knew not how to avoid her. Soon after saw a brig on our weather bow steering to the N.E. By this time the schooner was about three miles from us and four points forward of the beam. Expecting that she would keep on for the brig ahead of us, we tacked to the westward, keeping a little off from the wind to make good way through the water, to get clear of her if possible. She kept on to the eastward about ten or fifteen minutes after we had tacked, then wore round, set square sail, steering directly for us, came down upon us very fast, and was soon within gun shot of us, fired a gun and hoisted patriot colors and backed main topsail. She ran along to windward of us, hailed us to know where we were from, where bound, &c. then ordered me to come on board in my boat. Seeing that she was too powerful for us to resist, I accordingly went, and soon as I got along-side of the schooner, five ruffians instantly jumped into my boat, each of them being armed with a large knife, and told me to go on board the brig again; when they got on board
