I invite your attention to the propriety of making an appropriation to provide for any expenditure which it may be necessary to make in advance for the purpose of settling all our difficulties with the Mexican Republic.  It is my sincere desire to terminate, as it was originally to avoid, the existing war with Mexico by a peace just and honorable to both parties.  It is probable that the chief obstacle to be surmounted in accomplishing this desirable object will be the adjustment of a boundary between the two Republics which shall prove satisfactory and convenient to both, and such as neither will hereafter be inclined to disturb.  In the adjustment of this boundary we ought to pay a fair equivalent for any concessions which may be made by Mexico.

Under these circumstances, and considering the other complicated questions to be settled by negotiation with the Mexican Republic, I deem it important that a sum of money should be placed under the control of the Executive to be advanced, if need be, to the Government of that Republic immediately after their ratification of a treaty.  It might be inconvenient for the Mexican Government to wait for the whole sum the payment of which may be stipulated by this treaty until it could be ratified by our Senate and an appropriation to carry it into effect made by Congress.  Indeed, the necessity for this delay might defeat the object altogether.  The disbursement of this money would of course be accounted for, not as secret-service money, but like other expenditures.

Two precedents for such a proceeding exist in our past history, during the Administration of Mr. Jefferson, to which I would call your attention:  On the 26th February, 1803, an act was passed appropriating $2,000,000 “for the purpose of defraying any extraordinary expenses which may be incurred in the intercourse between the United States and foreign nations,” “to be applied under the direction of the President of the United States, who shall cause an account of the expenditure thereof to be laid before Congress as soon as may be;” and on the 13th of February, 1806, an appropriation was made of the same amount and in the same terms.  In neither case was the money actually drawn from the Treasury, and I should hope that the result in this respect might be similar on the present occasion, although the appropriation may prove to be indispensable in accomplishing the object.  I would therefore recommend the passage of a law appropriating $2,000,000 to be placed at the disposal of the Executive for the purpose which I have indicated.

In order to prevent all misapprehension, it is my duty to state that, anxious as I am to terminate the existing war with the least possible delay, it will continue to be prosecuted with the utmost vigor until a treaty of peace shall be signed by the parties and ratified by the Mexican Republic.
