_Seventh._ The Federal and State governments are parts of one system, alike necessary for the common prosperity, peace and security, and ought to be regarded alike with a cordial, habitual, and immovable attachment. Respect for the authority of each, and acquiescence in the just constitutional measures of each, are duties required by the plainest considerations of national, State and individual welfare. _Eighth._ That the series of acts of the Thirty-second Congress, the act known as the Fugitive Slave law included, are received and acquiesced in by the Whig party of the United States as a settlement in principle and substance of the dangerous and exciting questions which they embrace; and, so far as they are concerned, we will maintain them, and insist upon their strict enforcement, until time and experience shall demonstrate the necessity of further legislation to guard against the evasion of the laws on the one hand and the abuse of their powers on the other, not impairing their present efficiency; and we deprecate all further agitation of the question thus settled, as dangerous to our peace, and will discountenance all efforts to continue or renew such agitation, whenever, wherever, or however the attempt may be made; and we will maintain this system as essential to the nationality of the Whig party and the integrity of the Union.
