On the day following, as the Perry was about leaving Porto Grande, a letter was received from the British consul, in which he remarked, that he must be permitted to say, that he could not acknowledge the right of the American commander to question his conduct in the slightest degree; that when he gave a reply to the commander’s first letter, it was a mere act of courtesy upon his part; and that the language and bearing evinced in the last letter which he had received, compelled him to inform the commander that he declined any further correspondence, but to remark, that he should continue the course he had hitherto pursued, in denouncing all slave-vessels that came in his way, and should not fail to lay a copy of the correspondence before Her Majesty’s government. The Perry anchored in Porto Praya on the following day; and a letter was immediately addressed to the commodore, which furnished information of the occurrences at Porto Grande. The commander added, that in his interview, in company with the American consul, with the collector of the port, the collector had read to him a letter from the governor-general of the islands, from which it was evident that the Louisa Beaton had been denounced by the British consul. A copy of the governor-general’s letter having been requested, it was refused; but when it was intimated that he ought to have informed our consul of the action of the British consul in the case, and that the relations between the United States and Portugal were of a character which should lead him to communicate, promptly, any action or information given by a foreign officer, bearing upon American vessels or American interests; the collector replied to this that he would, if officially requested, communicate the required information. This was accordingly done. It was further stated, that, pending the correspondence, the British mail steam-packet arrived, with the Hon. David Tod, late American minister at the court of Brazil, on board, to whom the matter of the British consul’s interference was referred for counsel; and that the minister approved the course pursued, remarking that it was a case of unwarrantable interference on the part of a foreign officer, which, on our part, demanded prompt notice. While lying in Porto Praya, a suspicious-looking brigantine, under Brazilian colors, appeared off the harbor. The hull, rigging, maneuvering, and the number of men on board, indicated her to be a slaver. In a letter to the commodore, the agency of the Perry in the capture of this vessel was explained in the following terms.
