If this were not the case, the framers of the Constitution had expended much labor in vain. Had they imagined that Congress would possess no power to prohibit the trade either before or after 1808, they would not have taken so much care to protect the States against the exercise of this power before that period. Nay, more, they would not have attached such vast importance to this provision as to have excluded it from the possibility of future repeal or amendment, to which other portions of the Constitution were exposed. It would, then, have been wholly unnecessary to ingraft on the fifth article of the Constitution, prescribing the mode of its own future amendment, the proviso "that no amendment which may be made prior to the year 1808 shall in any manner affect" the provision in the Constitution securing to the States the right to admit the importation of African slaves previous to that period. According to the adverse construction, the clause itself, on which so much care and discussion had been employed by the members of the Convention, was an absolute nullity from the beginning, and all that has since been done under it a mere usurpation.
It was well and wise to confer this power on Congress, because had it been left to the States its efficient exercise would have been impossible. In that event any one State could have effectually continued the trade, not only for itself, but for all the other slave States, though never so much against their will. And why? Because African slaves, when once brought within the limits of any one State in accordance with its laws, can not practically be excluded from any State where slavery exists. And even if all the States had separately passed laws prohibiting the importation of slaves, these laws would have failed of effect for want of a naval force to capture the slavers and to guard the coast. Such a force no State can employ in time of peace without the consent of Congress.
These acts of Congress, it is believed, have, with very rare and insignificant exceptions, accomplished their purpose. For a period of more than half a century there has been no perceptible addition to the number of our domestic slaves. During this period their advancement in civilization has far surpassed that of any other portion of the African race. The light and the blessings of Christianity have been extended to them, and both their moral and physical condition has been greatly improved.
Reopen the trade and it would be difficult to determine whether the effect would be more deleterious on the interests of the master or on those of the native-born slave. Of the evils to the master, the one most to be dreaded would be the introduction of wild, heathen, and ignorant barbarians among the sober, orderly, and quiet slaves whose ancestors have been on the soil for several generations. This might tend to barbarize, demoralize, and exasperate the whole mass and produce most deplorable consequences.
The effect upon the existing slave would, if possible, be still more deplorable. At present he is treated with kindness and humanity. He is well fed, well clothed, and not overworked. His condition is incomparably better than that of the coolies which modern nations of high civilization have employed as a substitute for African slaves. Both the philanthropy and the self-interest of the master have combined to produce this humane result. But let this trade be reopened and what will be the effect? The same to a considerable extent as on a neighboring island, the only spot now on earth where the African slave trade is openly tolerated, and this in defiance of solemn treaties with a power abundantly able at any moment to enforce their execution. There the master, intent upon present gain, extorts from the slave as much labor as his physical powers are capable of enduring, knowing that when death comes to his relief his place can be supplied at a price reduced to the lowest point by the competition of rival African slave traders. Should this ever be the case in our country, which I do not deem possible, the present useful character of the domestic institution, wherein those too old and too young to work are provided for with care and humanity and those capable of labor are not overtasked, would undergo an unfortunate change. The feeling of reciprocal dependence and attachment which now exists between master and slave would be converted into mutual distrust and hostility.
But we are obliged as a Christian and moral nation to consider what would be the effect upon unhappy Africa itself if we should reopen the slave trade. This would give the trade an impulse and extension which it has never had, even in its palmiest days. The numerous victims required to supply it would convert the whole slave coast into a perfect pandemonium, for which this country would be held responsible in the eyes both of God and man. Its petty tribes would then be constantly engaged in predatory wars against each other for the purpose of seizing slaves to supply the American market. All hopes of African civilization would thus be ended.
On the other hand, when a market for African slaves shall no longer be furnished in Cuba, and thus all the world be closed against this trade, we may then indulge a reasonable hope for the gradual improvement of Africa. The chief motive of war among the tribes will cease whenever there is no longer any demand for slaves. The resources of that fertile but miserable country might then be developed by the hand of industry and afford subjects for legitimate foreign and domestic commerce. In this manner Christianity and civilization may gradually penetrate the existing gloom.
The wisdom of the course pursued by this Government toward China has been vindicated by the event. Whilst we sustained a neutral position in the war waged by Great Britain and France against the Chinese Empire, our late minister, in obedience to his instructions, judiciously cooperated with the ministers of these powers in all peaceful measures to secure by treaty the just concessions demanded by the interests of foreign commerce. The result is that satisfactory treaties have been concluded with China by the respective ministers of the United States, Great Britain, France, and Russia. Our "treaty, or general convention, of peace, amity, and commerce" with that Empire was concluded at Tien-tsin on the 18th June, 1858, and was ratified by the President, by and with the advice and consent of the Senate, on the 21st December following. On the 15th December, 1858, John E. Ward, a distinguished citizen of Georgia, was duly commissioned as envoy extraordinary and minister plenipotentiary to China.
He left the United States for the place of his destination on the 5th of February, 1859, bearing with him the ratified copy of this treaty, and arrived at Shanghai on the 28th May. From thence he proceeded to Peking on the 16th June, but did not arrive in that city until the 27th July. According to the terms of the treaty, the ratifications were to be exchanged on or before the 18th June, 1859. This was rendered impossible by reasons and events beyond his control, not necessary to detail; but still it is due to the Chinese authorities at Shanghai to state that they always assured him no advantage should be taken of the delay, and this pledge has been faithfully redeemed.
On the arrival of Mr. Ward at Peking he requested an audience of the Emperor to present his letter of credence. This he did not obtain, in consequence of his very proper refusal to submit to the humiliating ceremonies required by the etiquette of this strange people in approaching their sovereign. Nevertheless, the interviews on this question were conducted in the most friendly spirit and with all due regard to his personal feelings and the honor of his country. When a presentation to His Majesty was found to be impossible, the letter of credence from the President was received with peculiar honors by Kweiliang, "the Emperor's prime minister and the second man in the Empire to the Emperor himself." The ratifications of the treaty were afterwards, on the 16th of August, exchanged in proper form at Pei-tsang. As the exchange did not take place until after the day prescribed by the treaty, it is deemed proper before its publication again to submit it to the Senate. It is but simple justice to the Chinese authorities to observe that throughout the whole transaction they appear to have acted in good faith and in a friendly spirit toward the United States. It is true this has been done after their own peculiar fashion; but we ought to regard with a lenient eye the ancient customs of an empire dating back for thousands of years, so far as this may be consistent with our own national honor. The conduct of our minister on the occasion has received my entire approbation.
