The master of an American vessel, when calling on board, in company with the consul, communicated a report that the American brigantine Louisa Beaton, a few months previously, had been denounced by the British consul to the governor-general of these islands, as a vessel engaged in the slave-trade. The American consul had heard the report, but being informed that the information was communicated _unofficially_ to the governor-general, had taken no action in the case. The commander of the Perry, with the consul, then called on the collector of the port, and after learning the facts, addressed, on the 29th of September, a letter to the collector, requesting official information in reference to the agency that the British consul had had in inducing the governor-general of the Cape Verde Islands to direct a search to be made of the Louisa Beaton, on suspicion of her being engaged in the slave-trade. The collector, in reply, stated that the governor-general had not ordered any survey or visit on board the Louisa Beaton, but had directed him to state what was true in regard to the aforesaid vessel suspected of being employed in the slave-trade; as a representation had been made to his Excellency, by the consul for her British Majesty for these islands, in which the consul stated his belief that the said brig had on board irons, pots, and all other utensils and preparations necessary for that traffic; and also that he knew of a load of slaves being already bargained for, for the said vessel. A letter of the same day’s date was then addressed to her British Majesty’s consul, stating that the commander was credibly informed that, during the month of May he had denounced the Louisa Beaton to the governor-general, on suspicion of her being engaged in the slave-trade, and requested him to state by what authority he made the denunciation; also, the grounds upon which his suspicions of the illegal character of the vessel were founded. In reply, on the same day, the British consul stated that it was upon the very best authority that could be given; but he regretted that it was not in his power to name his authority. But that the character and former proceedings of the Louisa Beaton were quite sufficient to be referred to, to show that her proceedings were even then strongly suspected.
