In answer to your resolution of the 19th December last, I herewith transmit a letter from the Secretary of State and the accompanying documents.

To the Senate of the United States: I herewith transmit a letter from the Secretary of State, accompanied by copies of the correspondence asked for by your resolution of the 12th instant.

This subject is now submitted for the consideration of the Senate.

Texas had entered into the treaty of annexation upon the invitation of the Executive, and when for that act she was threatened with a renewal of the war on the part of Mexico she naturally looked to this Government to interpose its efforts to ward off the threatened blow.

By adopting that measure the United States will be in the exercise of an undoubted right.

Mexico has still to learn that however freely we may indulge in discussion among ourselves, the American people will tolerate no interference in their domestic affairs by any foreign government.

All nations are interested in enforcing an observance of those principles.

The negotiation failed, however, in this particular, out of no disinclination to abide by the terms of the treaty on the part of the Zollverein, but from a belief that it would not fully comport with its dignity to do so.

I submit it to your mature consideration whether, in view of the important benefits arising from the treaty to the trade and commerce of the United States and to their agriculture, it would not comport with sound policy to adopt that course.

I communicate to you an extract of a dispatch from Mr. Hall to the Secretary of State, which has been received by me since my message of the 3d instant, containing the pleasing intelligence that the indemnity assumed to be paid by the Republic of Venezuela in the case of the brig Morris has been satisfactorily arranged.

I have great pleasure in submitting to the Senate, for its ratification and approval, a treaty which has been concluded between Mr. Cushing, the United States commissioner, and the Chinese Empire.
