MEMORANDA.

☞The vessel mentioned in yesterday's paper, as having been plundered off Florida, is the Hamburgh ship Emma Sophia, Capt. Frahm—the supercargo is Mr. William Savage, of this town. It is stated in the Charleston papers that she is insured at Lloyd's.

We have been favoured with the following extract, giving further particulars:

Extract of a letter from a gentleman of this town, supercargo of the ship Emma Sophia, dated Havana, 31st Dec. 1818.

On Saturday 19th inst. between the Bahama Bank and Key Sal Bank we were boarded and taken possession of by a small schr. of about 30 tons, having one gun mounted on a pivot and 30 men. She manned us with twelve men, Spaniards, French, Germans and Americans, and carried us towards the Florida coast. Being arrived on the coast nearly opposite to Havana, the privateer went in shore to reconnoitre, and our ship lay off and on. Next morning she returned with two small vessels, a schooner and sloop. We then all four steered over the reef towards the small islands, and on Tuesday afternoon were brought to anchor in a little harbour formed by the Florida isles and the Martyr's Reef, as snug a hole as buccaniers would wish. They had seen no papers, but those of the ship and the Manifest, but the latter was enough, and they asked not for invoices or bills of lading. As soon as we anchored, they threw off our boats, took off the hatches and began to plunder the cargo. They loaded their two small vessels and another that came in next morning, besides taking our valuables on board the privateer. Having filled their vessels with linens and nankins, we had still many left, for our ship was full when we sailed from Hamburgh. Till Wednesday noon, our cabin had been respected, but then they came below and took packages of laces, gold watches from the trunks and other valuable goods. Every man had a knife about a foot long, which they brandished, swearing they would have money or something more valuable, that was concealed, or they would kill every soul of us, and they particularly threatened me. I appealed to their captain, told him I was in fear of my life, and went with him on board his privateer. He said he had no command, the crew would do as they pleased, that I need entertain no fear of my life, but had better tell at once if any thing was concealed. I told him there was not. After my return to the ship towards night, the pirates left us for the first time, and we hoped they had done with us. But next morning another sch'r and sloop appeared in the offing, and the privateer and one of the loaded sloops went out to meet them. They all returned together, the privateer anchored, and a boat's crew came towards us. I attempted to go on board the privateer to see her captain, but was ordered back. When they came on board, they said they had come to find where the gold &c. was, and that if we would not tell, they would hang every man of us and burn the ship. Davis, the spokesman, drew his knife and swore, that every man should die, unless he found the money, and first he would hang the supercargo. He called for a rope, which he had brought on board, fitted with a hangman's noose, sent a man up to the mizen yard and rove it and brought the noose down—and one man held it, and another stood ready to hoist. Now, said Davis, tell me where is the money, where are your diamonds, or I will hang you this minute. In vain I repeated
