Our late minister to Chili, Mr. Pendleton, has returned to the United States without having effected an adjustment in the second claim of the Macedonian, which is delayed on grounds altogether frivolous and untenable. Mr. Pendleton's successor has been directed to urge the claim in the strongest terms, and, in the event of a failure to obtain a prompt adjustment, to report the fact to the Executive at as early a day as possible, so that the whole matter may be communicated to Congress.

At your last session I submitted to the attention of Congress the convention with the Republic of Peru of the 17th March, 1841, providing for the adjustment of the claims of citizens of the United States against that Republic, but no definitive action was taken upon the subject. I again invite to it your attention and prompt action.

In my last annual message I felt it to be my duty to make known to Congress, in terms both plain and emphatic, my opinion in regard to the war which has so long existed between Mexico and Texas which since the battle of San Jacinto has consisted altogether of predatory incursions, attended by circumstances revolting to humanity. I repeat now what I then said, that after eight years of feeble and ineffectual efforts to reconquer Texas it was time that the war should have ceased. The United States have a direct interest in the question. The contiguity of the two nations to our territory was but too well calculated to involve our peace. Unjust suspicions were engendered in the mind of one or the other of the belligerents against us, and as a necessary consequence American interests were made to suffer and our peace became daily endangered; in addition to which it must have been obvious to all that the exhaustion produced by the war subjected both Mexico and Texas to the interference of other powers, which, without the interposition of this Government, might eventuate in the most serious injury to the United States. This Government from time to time exerted its friendly offices to bring about a termination of hostilities upon terms honorable alike to both the belligerents. Its efforts in this behalf proved unavailing. Mexico seemed almost without an object to persevere in the war, and no other alternative was left the Executive but to take advantage of the well-known dispositions of Texas and to invite her to enter into a treaty for annexing her territory to that of the United States.

Since your last session Mexico has threatened to renew the war, and has either made or proposes to make formidable preparations for invading Texas. She has issued decrees and proclamations, preparatory to the commencement of hostilities, full of threats revolting to humanity, and which if carried into effect would arouse the attention of all Christendom. This new demonstration of feeling, there is too much reason to believe, has been produced in consequence of the negotiation of the late treaty of annexation with Texas. The Executive, therefore, could not be indifferent to such proceedings, and it felt it to be due as well to itself as to the honor of the country that a strong representation should be made to the Mexican Government upon the subject. This was accordingly done, as will be seen by the copy of the accompanying dispatch from the Secretary of State to the United States envoy at Mexico. Mexico has no right to jeopard the peace of the world by urging any longer a useless and fruitless contest. Such a condition of things would not be tolerated on the European continent. Why should it be on this? A war of desolation, such as is now threatened by Mexico, can not be waged without involving our peace and tranquillity. It is idle to believe that such a war could be looked upon with indifference by our own citizens inhabiting adjoining States; and our neutrality would be violated in despite of all efforts on the part of the Government to prevent it. The country is settled by emigrants from the United States under invitations held out to them by Spain and Mexico. Those emigrants have left behind them friends and relatives, who would not fail to sympathize with them in their difficulties, and who would be led by those sympathies to participate in their struggles, however energetic the action of the Government to prevent it. Nor would the numerous and formidable bands of Indians--the most warlike to be found in any land--which occupy the extensive regions contiguous to the States of Arkansas and Missouri, and who are in possession of large tracts of country within the limits of Texas, be likely to remain passive. The inclinations of those numerous tribes lead them invariably to war whenever pretexts exist.

Mexico had no just ground of displeasure against this Government or people for negotiating the treaty. What interest of hers was affected by the treaty? She was despoiled of nothing, since Texas was forever lost to her. The independence of Texas was recognized by several of the leading powers of the earth. She was free to treat, free to adopt her own line of policy, free to take the course which she believed was best calculated to secure her happiness.

Her Government and people decided on annexation to the United States, and the Executive saw in the acquisition of such a territory the means of advancing their permanent happiness and glory. What principle of good faith, then, was violated? What rule of political morals trampled under foot? So far as Mexico herself was concerned, the measure should have been regarded by her as highly beneficial. Her inability to reconquer Texas had been exhibited, I repeat, by eight (now nine) years of fruitless and ruinous contest. In the meantime Texas has been growing in population and resources. Emigration has flowed into her territory from all parts of the world in a current which continues to increase in strength. Mexico requires a permanent boundary between that young Republic and herself. Texas at no distant day, if she continues separate and detached from the United States, will inevitably seek to consolidate her strength by adding to her domain the contiguous Provinces of Mexico. The spirit of revolt from the control of the central Government has heretofore manifested itself in some of those Provinces, and it is fair to infer that they would be inclined to take the first favorable opportunity to proclaim their independence and to form close alliances with Texas. The war would thus be endless, or if cessations of hostilities should occur they would only endure for a season. The interests of Mexico, therefore, could in nothing be better consulted than in a peace with her neighbors which would result in the establishment of a permanent boundary. Upon the ratification of the treaty the Executive was prepared to treat with her on the most liberal basis. Hence the boundaries of Texas were left undefined by the treaty. The Executive proposed to settle these upon terms that all the world should have pronounced just and reasonable. No negotiation upon that point could have been undertaken between the United States and Mexico in advance of the ratification of the treaty. We should have had no right, no power, no authority, to have conducted such a negotiation, and to have undertaken it would have been an assumption equally revolting to the pride of Mexico and Texas and subjecting us to the charge of arrogance, while to have proposed in advance of annexation to satisfy Mexico for any contingent interest she might have in Texas would have been to have treated Texas not as an independent power, but as a mere dependency of Mexico. This assumption could not have been acted on by the Executive without setting at defiance your own solemn declaration that that Republic was an independent State. Mexico had, it is true, threatened war against the United States in the event the treaty of annexation was ratified. The Executive could not permit itself to be influenced by this threat. It represented in this the spirit of our people, who are ready to sacrifice much for peace, but nothing to intimidation. A war under any circumstances is greatly to be deplored, and the United States is the last nation to desire it; but if, as the condition of peace, it be required of us to forego the unquestionable right of treating with an independent power of our own continent upon matters highly interesting to both, and that upon a naked and unsustained pretension of claim by a third power to control the free will of the power with whom we treat, devoted as we may be to peace and anxious to cultivate friendly relations with the whole world, the Executive does not hesitate to say that the people of the United States would be ready to brave all consequences sooner than submit to such condition. But no apprehension of war was entertained by the Executive, and I must express frankly the opinion that had the treaty been ratified by the Senate it would have been followed by a prompt settlement, to the entire satisfaction of Mexico, of every matter in difference between the two countries. Seeing, then, that new preparations for hostile invasion of Texas were about to be adopted by Mexico, and that these were brought about because Texas had adopted the suggestions of the Executive upon the subject of annexation, it could not passively have folded its arms and permitted a war, threatened to be accompanied by every act that could mark a barbarous age, to be waged against her because she had done so.

Other considerations of a controlling character influenced the course of the Executive. The treaty which had thus been negotiated had failed to receive the ratification of the Senate. One of the chief objections which was urged against it was found to consist in the fact that the question of annexation had not been submitted to the ordeal of public opinion in the United States. However untenable such an objection was esteemed to be, in view of the unquestionable power of the Executive to negotiate the treaty and the great and lasting interests involved in the question, I felt it to be my duty to submit the whole subject to Congress as the best expounders of popular sentiment. No definitive action having been taken on the subject by Congress, the question referred itself directly to the decision of the States and people. The great popular election which has just terminated afforded the best opportunity of ascertaining the will of the States and the people upon it. Pending that issue it became the imperative duty of the Executive to inform Mexico that the question of annexation was still before the American people, and that until their decision was pronounced any serious invasion of Texas would be regarded as an attempt to forestall their judgment and could not be looked upon with indifference. I am most happy to inform you that no such invasion has taken place; and I trust that whatever your action may be upon it Mexico will see the importance of deciding the matter by a resort to peaceful expedients in preference to those of arms. The decision of the people and the States on this great and interesting subject has been decisively manifested. The question of annexation has been presented nakedly to their consideration. By the treaty itself all collateral and incidental issues which were calculated to divide and distract the public councils were carefully avoided. These were left to the wisdom of the future to determine. It presented, I repeat, the isolated question of annexation, and in that form it has been submitted to the ordeal of public sentiment. A controlling majority of the people and a large majority of the States have declared in favor of immediate annexation. Instructions have thus come up to both branches of Congress from their respective constituents in terms the most emphatic. It is the will of both the people and the States that Texas shall be annexed to the Union promptly and immediately. It may be hoped that in carrying into execution the public will thus declared all collateral issues may be avoided. Future Legislatures can best decide as to the number of States which should be formed out of the territory when the time has arrived for deciding that question. So with all others. By the treaty the United States assumed the payment of the debts of Texas to an amount not exceeding $10,000,000, to be paid, with the exception of a sum falling short of $400,000, exclusively out of the proceeds of the sales of her public lands. We could not with honor take the lands without assuming the full payment of all incumbencies upon them.

Nothing has occurred since your last session to induce a doubt that the dispositions of Texas remain unaltered. No intimation of an altered determination on the part of her Government and people has been furnished to the Executive. She still desires to throw herself under the protection of our laws and to partake of the blessings of our federative system, while every American interest would seem to require it. The extension of our coastwise and foreign trade to an amount almost incalculable, the enlargement of the market for our manufactures, a constantly growing market for our agricultural productions, safety to our frontiers, and additional strength and stability to the Union--these are the results which would rapidly develop themselves upon the consummation of the measure of annexation. In such event I will not doubt but that Mexico would find her true interest to consist in meeting the advances of this Government in a spirit of amity. Nor do I apprehend any serious complaint from any other quarter; no sufficient ground exists for such complaint. We should interfere in no respect with the rights of any other nation. There can not be gathered from the act any design on our part to do so with their possessions on this continent. We have interposed no impediments in the way of such acquisitions of territory, large and extensive as many of them are, as the leading powers of Europe have made from time to time in every part of the world. We seek no conquest made by war. No intrigue will have been resorted to or acts of diplomacy essayed to accomplish the annexation of Texas. Free and independent herself, she asks to be received into our Union. It is a question for our own decision whether she shall be received or not.

The two Governments having already agreed through their respective organs on the terms of annexation, I would recommend their adoption by Congress in the form of a joint resolution or act to be perfected and made binding on the two countries when adopted in like manner by the Government of Texas.

In order that the subject may be fully presented in all its bearings, the correspondence which has taken place in reference to it since the adjournment of Congress between the United States, Texas, and Mexico is herewith transmitted.
