This vessel was fashioned, at the will of avarice, for the aid of cruelty and injustice; it was an African slaver--the schooner Panda. She was commanded by Don Pedro Gilbert, a native of Catalonia, in Spain, and son of a grandee; a man thirty-six years of age, and exceeding handsome, having a round face, pearly teeth, round forehead, and full black eyes, with beautiful raven hair, and a great favorite with the ladies. He united great energy, coolness and decision, with superior knowledge in mercantile transactions, and the Guinea trade; having made several voyages after slaves. The mate and owner of the Panda was Don Bernardo De Soto, a native of Corunna, Spain, and son, of Isidore De Soto, manager of the royal revenue in said city; he was now twenty-five years of age, and from the time he was fourteen had cultivated the art of navigation, and at the age of twenty-two had obtained the degree of captain in the India service. After a regular examination the correspondent diploma was awarded him. He was married to Donna Petrona Pereyra, daughter of Don Benito Pereyra, a merchant of Corunna. She was at this time just fifteen, and ripening into that slight fullness of form, and roundness of limb, which in that climate mark the early passing from girl into woman. Her complexion was the dark olive tinge of Spain; her eyes jet black, large and lustrous. She had great sweetness of disposition and ingenuousness. To the strictest discipline De Soto united the practical knowledge of a thorough seaman. But "the master spirit of the whole," was Francisco Ruiz, the carpenter of the Panda. This individual was of the middle size, but muscular, with a short neck. His hair was black and abundant, and projected from his forehead, so that he appeared to look out from under it, like a bonnet. His eyes were dark chestnut, but always restless; his features were well defined; his eye-lashes, jet black. He was familiar with all the out-of-the-way places of the Havana, and entered into any of the dark abodes without ceremony. From report his had been a wild and lawless career. The crew were chiefly Spaniards, with a few Portuguese, South Americans, and half castes. The cook was a young Guinea negro, with a pleasant countenance, and good humored, with a sleek glossy skin, and tatooed on the face; and although entered in the schooner's books as free, yet was a slave. In all there were about forty men. Her cargo was an assorted one, consisting in part of barrels of rum, and gunpowder, muskets, cloth, and numerous articles, with which to purchase slaves.
