Failure of the American Squadron to capture Slave-Vessels—Causes of that Failure—High character of the Commodore and Commander—Similar ill-success of the French Squadron—Success of the English, and why—Results effected by the American Squadron.

It will not have escaped the reader's notice, that the foregoing journal of our cruise records not the capture of a single slave-vessel, either by our own ship or any other belonging to the American squadron. Such is the fact, and such it must inevitably be, so long as the circumstances, which prevented our efficiency in that respect, shall continue to exist. The doctrines relative to the right of search, held by our Government and cordially sanctioned by the people, declare that the cruisers of no foreign nation have a right to search, visit, or in any way detain an American vessel on the high seas. Denying the privilege to others, we must of course allow the same inviolability to a foreign flag, as we assert for that of our own country. Hence, our national ships can detain or examine none but American vessels, or those which they find sailing under the American flag. But no slave-vessel would display this flag. The laws of the United States declare the slave-trade, if exercised by any of its citizens, to be piracy, and punishable with death; the laws of Spain, Portugal and Brazil, are believed to be different, or, at least, if they threaten the same penalty, are certain never to inflict it. Consequently, all slaves will be careful to sail under the flag of one of these latter nations, and thus avoid the danger of losing life as well as property, in the event of capture.

Undoubtedly, many American vessels have been sold to foreigners, by unprincipled citizens of our country, with a belief or full understanding that they were to be employed in this nefarious trade. In some instances, such vessels have been sold, with stipulations in the contract, binding the seller to deliver them at slave-stations on the coast of Africa; they have been sent out to those stations under American colors, and commanded by American captains; and there, being transferred to new masters, they have immediately taken on board their cargoes of human flesh. But how is an American cruiser to take hold of a vessel so circumstanced? On her departure from the United States, and until the transfer takes place, she is provided with regular papers, and probably sails for her destined port with a cargo which may be used in lawful, as well as unlawful trade. After the transfer, she appears under foreign colors, is furnished with foreign papers, commanded by a foreign master, and manned by a foreign crew. It is not to be presumed that this change of nationality will be effected in presence of one of our men-of-war. How then can such a vessel be taken or molested, so long as the present treaties and laws continue in force?

It is well that the public should be prepared for an inefficiency which can hardly fail to continue; and, in justice to the American squadron, it should be imputed to the true cause, and not to any lack of energy or good-will on the part of the officers. Whatever be their zeal (and hitherto they have been active and indefatigable), it is almost certain that their efforts will not be crowned with success, in the capture of a single prize. The Commodore, under whose general direction we have acted, is a gentleman of the highest professional character, persevering, sagacious, and determined, and well known as such, both in and out of the service. The commanders of the different vessels were likewise men of elevated character, zealous in performing their duty, and honorably ambitious of distinction. If the incentive of gain be reckoned stronger than considerations of duty and honor, it was not wanting; for, besides half the value of the vessel, each liberated slave would have been worth twenty-five dollars to the captors—a handsome amount of prize-money, in a cargo of six or eight hundred.

The French, like ourselves, having no reciprocal treaties with Spain, Portugal, and Brazil, are equally unsuccessful in making prizes. Eleven of their vessels of war were stationed on the coast, during the period of our cruise, but effected not a single capture. England, by virtue of her treaties with the three nations above mentioned, empowers her cruisers to take slave-vessels under either of their flags. Hence the success of the English commanders; a success which is sometimes tauntingly held up, in contrast with what is most unjustly termed the sluggishness of our own squadron.

Still, the presence of American national vessels, on the coast of Africa, has not been unattended with results that may partly compensate for the sacrifice of human life and health, which the climate renders inevitable. The trade of the United States has been protected. The natives have been taught, that the humblest American merchant-vessel sails under the shadow of a flag, which guarantees security to everything that it covers. The colonies of Liberia have been made more respectable in the eyes of the barbarian nations that surround them. This latter advantage it is creditable to our country to bestow; for the United States demand from Liberia no commercial exemptions, nor anything in return for the countenance which she lends to that growing commonwealth. Never before, perhaps, did a colony exist, so entirely free from vexatious interference on the part of the mother-country, and so carefully fostered by the benevolence that planted it. Slight as is the present political connection between the United States and Liberia, the latest advices inform us that it is in contemplation to sever the silken thread. The Colonization Society, I understand, is discussing the expediency of relinquishing its further control over the government, and allowing the infant colony to take a place among independent nations. Should this event come to pass, and Liberia either find the protection of another maritime power, or prove adequate to protect herself, there will be one reason the less for sending a squadron of gallant ships to chase shadows in a deadly climate.

THE END.
