It is due to candor, as well as to my own feelings, that I should express the reluctance and anxiety which I must at all times experience in exercising the undoubted right of the Executive to withhold his assent from bills on other grounds than their constitutionality. That this right should not be exercised on slight occasions all will admit. It is only in matters of deep interest, when the principle involved may be justly regarded as next in importance to infractions of the Constitution itself, that such a step can be expected to meet with the approbation of the people. Such an occasion do I conscientiously believe the present to be. In the discharge of this delicate and highly responsible duty I am sustained by the reflection that the exercise of this power has been deemed consistent with the obligation of official duty by several of my predecessors, and by the persuasion, too, that whatever liberal institutions may have to fear from the encroachments of Executive power, which has been everywhere the cause of so much strife and bloody contention, but little danger is to be apprehended from a precedent by which that authority denies to itself the exercise of powers that bring in their train influence and patronage of great extent, and thus excludes the operation of personal interests, everywhere the bane of official trust. I derive, too, no small degree of satisfaction from the reflection that if I have mistaken the interests and wishes of the people the Constitution affords the means of soon redressing the error by selecting for the place their favor has bestowed upon me a citizen whose opinions may accord with their own. I trust, in the meantime, the interests of the nation will be saved from prejudice by a rigid application of that portion of the public funds which might otherwise be applied to different objects to that highest of all our obligations, the payment of the public debt, and an opportunity be afforded for the adoption of some better rule for the operations of the Government in this matter than any which has hitherto been acted upon. Profoundly impressed with the importance of the subject, not merely as relates to the general prosperity of the country, but to the safety of the federal system, I can not avoid repeating my earnest hope that all good citizens who take a proper interest in the success and harmony of our admirable political institutions, and who are incapable of desiring to convert an opposite state of things into means for the gratification of personal ambition, will, laying aside minor considerations and discarding local prejudices, unite their honest exertions to establish some fixed general principle which shall be calculated to effect the greatest extent of public good in regard to the subject of internal improvement, and afford the least ground for sectional discontent.
