in reference to Hungary and her people.  I also transmit, in compliance with the resolution of the Senate, but in a separate packet, a copy of the correspondence of Mr. Mann with the Department of State.  The latter I have caused to be marked “executive”—­the information contained in it being such as will be found on examination most appropriately to belong to the Senate in the exercise of its executive functions.  The publication of this correspondence of the agent sent by me to Hungary is a matter referred entirely to the judgment and discretion of the Senate.

It will be seen by the documents now transmitted that no minister or agent was accredited by the Government of Hungary to this Government at any period since I came into office, nor was any communication ever received by this Government from the minister of foreign affairs of Hungary or any other executive officer authorized to act in her behalf.

My purpose, as freely avowed in this correspondence, was to have acknowledged the independence of Hungary had she succeeded in establishing a government de facto on a basis sufficiently permanent in its character to have justified me in doing so according to the usages and settled principles of this Government; and although she is now fallen and many of her gallant patriots are in exile or in chains, I am free still to declare that had she been successful in the maintenance of such a government as we could have recognized we should have been the first to welcome her into the family of nations.

WASHINGTON, April 3, 1850.

To the Senate and House of Representatives of the United States:

I transmit a translation of a note, under date the 20th of last month, addressed to the Secretary of State by the minister of the Mexican Republic accredited to this Government, expressing the views of that Government with reference to the control of the wild Indians of the United States on the frontier of Mexico, as stipulated for in the eleventh article of the treaty of Guadalupe Hidalgo.

WASHINGTON, April 22, 1850.

To the Senate of the United States:

I herewith transmit to the Senate, for their advice with regard to its ratification, a convention between the United States and Great Britain, concluded at Washington on the 19th instant by John M. Clayton, Secretary of State, on the part of the United States, and by the Right Hon. Sir Henry Lytton Bulwer, on the part of Great Britain.

This treaty has been negotiated in accordance with the general views expressed in my message to Congress in December last.  Its object is to establish a commercial alliance with all great maritime states for the protection of a contemplated ship canal through the territory of Nicaragua to connect the Atlantic and Pacific oceans, and at the same time to insure the same protection to the contemplated railways or canals by the Tehuantepec and Panama routes, as well as to every other interoceanic communication which may be adopted to shorten the transit to or from our territories on the Pacific.
