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 founded 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.

It would be a useless repetition to do more than refer with earnest commendation to my former recommendations in favor of the Pacific railroad; of the grant of power to the President to employ the naval force in the vicinity for the protection of the lives and property of our fellow-citizens passing in transit over the different Central American routes against sudden and lawless outbreaks and depredations, and also to protect American merchant vessels, their crews and cargoes, against violent and unlawful seizure and confiscation in the ports of Mexico and the South American Republics when these may be in a disturbed and revolutionary condition.  It is my settled conviction that without such a power we do not afford that protection to those engaged in the commerce of the country which they have a right to demand.

I again recommend to Congress the passage of a law, in pursuance of the provisions of the Constitution, appointing a day certain previous to the 4th March in each year of an odd number for the election of Representatives throughout all the States.  A similar power has already been exercised, with general approbation, in the appointment of the same day throughout the Union for holding the election of electors for President
