To the Senate of the United States:

I herewith communicate to the Senate, for its consideration, two conventions concluded by the minister of the United States at Berlin—the one with the Kingdom of Wurtemberg, dated on the 10th day of April, and the other with the Grand Duchy of Hesse, dated on the 26th day of March, 1844—for the mutual abolition of the droit d'aubaine and the droit de detraction between those Governments and the United States, and I communicate with the conventions copies of the correspondence necessary to explain the reasons for concluding them.

JOHN TYLER.

WASHINGTON, May 15, 1844.

To the Senate of the United States:

In answer to the resolution of the Senate of the 13th instant, requesting to be informed "whether, since the commencement of the negotiations which resulted in the treaty now before the Senate for the annexation of Texas to the United States, any military preparation has been made or ordered by the President for or in anticipation of war, and, if so, for what cause, and with whom was such war apprehended, and what are the preparations that have been made or ordered; has any movement or assemblage or disposition of any of the military or naval forces of the United States been made or ordered with a view to such hostilities; and to communicate to the Senate copies of all orders or directions given for any such preparation or for any such movement or disposition or for the future conduct of such military or naval forces," I have to inform the Senate that, in consequence of the declaration of Mexico communicated to this Government and by me laid before Congress at the opening of its present session, announcing the determination of Mexico to regard as a declaration of war against her by the United States the definitive ratification of any treaty with Texas annexing the territory of that Republic to the United States, and the hope and belief entertained by the Executive that the treaty with Texas for that purpose would be speedily approved and ratified by the Senate, it was regarded by the Executive to have become emphatically its duty to concentrate in the Gulf of Mexico and its vicinity, as a precautionary measure, as large a portion of the home squadron, under the command of Captain Conner, as could well be drawn together, and at the same time to assemble at Fort Jesup, on the borders of Texas, as large a military force as the demands of the service at other encampments would authorize to be detached. For the number of ships already in the Gulf and the waters contiguous thereto and such as are placed under orders for that destination, and of troops now assembled upon the frontier, I refer you to the accompanying reports from the Secretaries of the War and Navy Departments. It will also be perceived by the Senate, by referring to the orders of the Navy Department which are herewith transmitted, that the naval officer in command of the fleet is directed to cause his ships to perform all the duties of a fleet of observation and to apprise the Executive of any indication of a hostile design upon Texas on the part of any nation pending the deliberations of the Senate upon the treaty, with a view that the same should promptly be submitted to Congress for its mature deliberation. At the same time, it is due to myself that I should declare it as my opinion that the United States having by the treaty of annexation acquired a title to Texas which requires only the action of the Senate to perfect it, no other power could be permitted to invade and by force of arms to possess itself of any portion of the territory of Texas pending your deliberations upon the treaty without placing itself in an hostile attitude to the United States and justifying the employment of any military means at our disposal to drive back the invasion. At the same time, it is my opinion that Mexico of any other power will find in your approval of the treaty no just cause of war against the United States, nor do I believe that there is any serious hazard of war to be found in the fact of such approval. Nevertheless, every proper measure will be resorted to by the Executive to preserve upon an honorable and just basis the public peace by reconciling Mexico, through a liberal course of policy, to the treaty.

JOHN TYLER.

WASHINGTON, May 15, 1844.

To the Senate of the United States:

In answer to the resolution of the Senate of the 13th instant, requesting to be informed "whether a messenger has been sent to Mexico with a view to obtain her consent to the treaty with Texas, and, if so, to communicate to the Senate a copy of the dispatches of which he is bearer and a copy of the instructions given to said messenger; and also to inform the Senate within what time said messenger is expected to return," I have to say that no messenger has been sent to Mexico in order to obtain her assent to the treaty with Texas, it not being regarded by the Executive as in any degree requisite to obtain such consent in order (should the Senate ratify the treaty) to perfect the title of the United States to the territory thus acquired, the title to the same being full and perfect without the assent of any third power. The Executive has negotiated with Texas as an independent power of the world, long since recognized as such by the United States and other powers, and as subordinate in all her rights of full sovereignty to no other power. A messenger has been dispatched to our minister at Mexico as bearer of the dispatch already communicated to the Senate, and which is to be found in the letter addressed to Mr. Green, and forms a part of the documents ordered confidentially to be printed for the use of the Senate. That dispatch was dictated by a desire to preserve the peace of the two countries by denying to Mexico all pretext for assuming a belligerent attitude to the United States, as she had threatened to do, in the event of the annexation of Texas to the United States, by the dispatch of her Government which was communicated by me to Congress at the opening of its present session. The messenger is expected to return before the 15th of June next, but he may be detained to a later day. The recently appointed envoy from the United States to Mexico will be sent so soon as the final action is had on the question of annexation, at which time, and not before, can his instructions be understandingly prepared.
