Mr. Adams had the satisfaction of receiving from Hyde de Neuville, the French minister, an assurance of his coincidence of opinion with him, and that he had written to his own government that the proceedings of General Jackson had been right, particularly in respect of the two Englishmen. Although there was a difference of opinion on the subject among the members of the diplomatic body, he declared that his own was that such incendiaries and instigators of savage barbarities should be put to death.

On one occasion, the President expressed to Mr. Adams his astonishment at the malignancy of the reports which some newspapers were circulating concerning him, and asked in what motives they could have originated. Mr. Adams replied, that the motives did not lie very deep; that there had been a spirit at work, ever since he came to Washington, very anxious to find or make occasions of censure upon him. That spirit he could not lay. His only resource was to pursue his course according to his own sense of right, and abide by the consequences. To which the President fully assented.

While these events were agitating the political world, Mr. Adams was called to lament the death of his mother, dear to his heart by every tie of affection and gratitude. His feelings burst forth, on the occasion, in eloquent and touching tributes to her memory. "This is one of the severest afflictions," he exclaimed, "to which human existence is liable. The silver cord is broken,—the tenderest of natural ties is dissolved,—life is no longer to me what it was,—my home is no longer the abode of my mother. While she lived, whenever I returned to the paternal roof, I felt as if the joys and charms of childhood returned to make me happy; all was kindness and affection. At once silent and active as the movement of the orbs of heaven, one of the links which connected me with former ages is no more. May a merciful Providence spare for many future years my only remaining parent!"

The policy of the friends and enemies of Mr. Monroe's administration was developed by the debates in the House of Representatives on the Seminole war, and the spirit of intrigue began to operate with great publicity. Some of the Western friends of Mr. Adams proposed to him measures of counteraction, on which he remarked: "These overtures afford opportunities and temptations to intrigue, of which there is much in this government, and without which the prospects of a public man are desperate. Caballing with members of Congress for future contingency has become so interwoven with the practical course of our government, and so inevitably flows from the practice of canvassing by the members to fix on candidates for President and Vice-President, that to decline it is to pass a sentence of total exclusion. Be it so! Whatever talents I possess, that of intrigue is not among them. And instead of toiling for a future election, as I am recommended to do, my only wisdom is to prepare myself for voluntary, or unwilling, retirement." On the same topic, in February, 1819, he thus expressed himself: "The practice which has grown up under the constitution, but contrary to its spirit, by which members of Congress meet in caucus and determine by a majority the candidates for the Presidency and Vice-Presidency to be supported by the whole meeting, places the President in a state of undue subserviency to the members of the legislature; which, connected with the other practice of reëlecting only once the same President, leads to a thousand corrupt cabals between the members of Congress and heads of departments, who are thus made, almost necessarily, rival pretenders to the succession. The only possible chance for a head of a department to attain the Presidency is by ingratiating himself with the members of Congress; and as many of them have objects of their own to obtain, the temptation is immense to corrupt coalitions, and tends to make all the public offices objects of bargain and sale."

The treaty with Spain, by which the United States acquired the Floridas, was signed by Onis and Adams on the 22d of December, 1819. To effect this treaty, so full of difficulty and responsibility, Mr. Adams had labored ever since he had become Secretary of State. His success was to him a subject of intense gratification; especially the acknowledgment of the right of the United States to a definite line of boundary to the South Sea. This right was not among our claims by the treaty of peace with Great Britain, nor among our pretensions under the purchase of Louisiana, for that gave the United States only the range of the Mississippi and its waters. Mr. Adams regarded the attainment of it as his own; as he had first proposed it on his own responsibility, and introduced it in his discussions with Onis and De Neuville. Its final attainment, under such circumstances, was a just subject of exultation, which was increased by the change of relations which the treaty produced with Spain, from the highest state of exasperation and imminent war, to a fair prospect of tranquillity and secure peace. The treaty was ratified by the President, with the unanimous advice of the Senate.

In 1819 a committee of the Colonization Society applied to the President for the purchase of a territory on the coast of Africa, to which the slaves rescued under the act of Congress, then recently passed, against piracy and the slave-trade, might be sent. The subject being referred to Mr. Adams, he stated in reply that it was impossible that Congress could have intended to authorize the purchase of territory by that act, for they had only appropriated for its object one hundred thousand dollars, which was a sum utterly inadequate for the purchase of a territory on the coast of Africa. He declared also that he had no opinion of the practicability or usefulness of the objects proposed by the Colonization Society, of establishing in Africa a colony composed of the free blacks sent from the United States. "The project," said he, "is professedly formed, 1st, without making use of any compulsion on the free people of color to go to Africa. 2d. To encourage the emancipation of slaves by their masters. 3d. To promote the entire abolition of slavery; and yet, 4th, without in the slightest degree affecting what they call 'a certain species of property in slaves.' There are men of all sorts and descriptions concerned in this Colonization Society: some exceedingly humane, weak-minded men, who really have no other than the professed objects in view, and who honestly believe them both useful and attainable; some speculators in official profits and honors, which a colonial establishment would of course produce; some speculators in political popularity, who think to please the abolitionists by their zeal for emancipation, and the slaveholders by the flattering hope of ridding them of the free colored people at the public expense; lastly, some cunning slaveholders, who see that the plan may be carried far enough to produce the effect of raising the market price of their slaves. But, of all its other difficulties, the most objectionable is that it obviously includes the engrafting a colonial establishment upon the constitution of the United States, and thereby an accession of power to the national government transcending all its other powers."

The friends of the measure urged in its favor that it had been recommended by the Legislature of Virginia. They enlarged on the happy condition of slaves in that state, on the kindness with which they were treated, and on the attachment subsisting between them and their masters. They stated that the feeling against slavery was so strong that shortly after the close of the Revolution many persons had voluntarily emancipated their slaves. This had introduced a class of very dangerous people,—the free blacks,—who lived by pilfering, corrupted the slaves, and produced such pernicious consequences that the Legislature was obliged to prohibit their further emancipation by law. The important object now was to remove the free blacks, and provide a place to which the emancipated slaves might go; in which case, the legal obstacles to emancipation being withdrawn, Virginia, at least, might in time be relieved from her black population.

A committee from the Colonial Society also waited on Mr. Adams, repeating the same topics, and maintaining that the slave-trade act contained a clear authority to settle a colony in Africa; and that the purchase of Louisiana, and the settlement at the mouth of Columbia River, placed beyond all question the right of acquiring territory as existing in the government of the United States. Mr. Adams, in reply, successfully maintained that the slave-trade act had no reference to the settlement of a colony on the coast of Africa; and that the acquisition of Louisiana, and the settlement at the mouth of Columbia River, being in territories contiguous to and in continuance of our own, could by no reason warrant the purchase of countries beyond seas, or the establishment of a colonial system of government subordinate to and dependent upon that of the United States.

In July, 1819, Mr. Adams, writing concerning the failure at the preceding session of Missouri to obtain admission as a state into the Union, from the restriction, introduced by the House of Representatives, excluding slavery from its constitution, thus expressed himself: "The attempt to introduce that restriction produced a violent agitation among the members from the slaveholding states, and it has been communicated to the states themselves, and to the territory of Missouri. The slave-drivers, as usual, whenever this topic is brought up, bluster and bully, talk of the white slaves of the Eastern States, and the dissolution of the Union, and of oceans of blood; and the Northern men, as usual, pocket all this hectoring, sit down in quiet, and submit to the slave-scourging republicanism of the planters."

Being urged to use his influence that the language and policy of the government should be as moderate and guarded as possible, from the consideration that both England and France were profoundly impressed with the idea that we were an ambitious, encroaching people, Mr. Adams replied: "I doubt if we should give ourselves any concern about it. Great Britain, who had been vilifying us for twenty years as a low-minded nation, with no generous ambition, no God but gold, had now changed her tune, and was endeavoring to alarm the world at the gigantic grasp of our ambition. Spain and all Europe were endeavoring to do the same; being startled at first by our acquisition of Louisiana, and now by our pretensions to extend to the South Sea. Nothing we can say will remove this impression until the world shall be familiarized with the idea of considering the continent of North America to be our proper dominion. From the time we became an independent people, it was as much a law of nature that this should become our pretension, as that the Mississippi should flow to the sea. Spain had pretensions on our southern, Great Britain on our northern borders. It was impossible that centuries should elapse without finding them annexed to the United States; not from any spirit of encroachment or of ambition on our part, but because it was a physical, and moral, and political absurdity, that such fragments of territory, with sovereigns fifteen hundred miles beyond sea, worthless and burdensome to their owners, should exist, permanently, contiguous to a great, powerful, enterprising, and rapidly-growing nation. Most of the territories of Spain in our neighborhood had become ours by fair purchase. This rendered it more unavoidable that the remainder of the continent should ultimately be ours. It was but very lately we had seen this ourselves, or that we had avowed the pretension of extending to the South Sea; and, until Europe finds it to be a settled geographical element that the United States and North America are identical, any effort on our part to reason the world out of the belief that we are an ambitious people will have no other effect than to convince them that we add to our ambition hypocrisy."
