Should Congress avail itself of this additional source of revenue, not only would the amount of the public loan rendered necessary by the war with Mexico be diminished to that extent, but the public credit and the public confidence in the ability and determination of the Government to meet all its engagements promptly would be more firmly established, and the reduced amount of the loan which it may be necessary to negotiate could probably be obtained at cheaper rates. Congress is therefore called upon to determine whether it is wiser to impose the war duties recommended or by omitting to do so increase the public debt annually $3,000,000 so long as loans shall be required to prosecute the war, and afterwards provide in some other form to pay the semiannual interest upon it, and ultimately to extinguish the principal. If in addition to these duties Congress should graduate and reduce the price of such of the public lands as experience has proved will not command the price placed upon them by the Government, an additional annual income to the Treasury of between half a million and a million of dollars, it is estimated, would be derived from this source. Should both measures receive the sanction of Congress, the annual amount of public debt necessary to be contracted during the continuance of the war would be reduced near $4,000,000. The duties recommended to be levied on tea and coffee it is proposed shall be limited in their duration to the end of the war, and until the public debt rendered necessary to be contracted by it shall be discharged. The amount of the public debt to be contracted should be limited to the lowest practicable sum, and should be extinguished as early after the conclusion of the war as the means of the Treasury will permit.
