It ought in justice to be observed that several of the estimates from the Departments for the year ending June 30, 1860, were reduced by Congress below what was and still is deemed compatible with the public interest. Allowing a liberal margin of $2,500,000 for this reduction and for other causes, it may be safely asserted that the sum of $61,000,000, or, at the most, $62,000,000, is amply sufficient to administer the Government and to pay the interest on the public debt, unless contingent events should hereafter render extraordinary expenditures necessary. This result has been attained in a considerable degree by the care exercised by the appropriate Departments in entering into public contracts. I have myself never interfered with the award of any such contract, except in a single case, with the Colonization Society, deeming it advisable to cast the whole responsibility in each case on the proper head of the Department, with the general instruction that these contracts should always be given to the lowest and best bidder. It has ever been my opinion that public contracts are not a legitimate source of patronage to be conferred upon personal or political favorites, but that in all such cases a public officer is bound to act for the Government as a prudent individual would act for himself. It is with great satisfaction I communicate the fact that since the date of my last annual message not a single slave has been imported into the United States in violation of the laws prohibiting the African slave trade. This statement is rounded upon a thorough examination and investigation of the subject. Indeed, the spirit which prevailed some time since among a portion of our fellow-citizens in favor of this trade seems to have entirely subsided. I also congratulate you upon the public sentiment which now exists against the crime of setting on foot military expeditions within the limits of the United States to proceed from thence and make war upon the people of unoffending States with whom we are at peace. In this respect a happy change has been effected since the commencement of my Administration. It surely ought to be the prayer of every Christian and patriot that such expeditions may never again receive countenance in our country or depart from our shores.
