Mr. Ruffin, of North Carolina, moved to postpone the consideration of the same indefinitely, and the resolution was thereupon postponed by the following vote:

Ayes.—Delaware, Kentucky, Maryland, Missouri, New Jersey, North Carolina, Ohio, Rhode Island, Tennessee, and Virginia—10.

Noes.—Connecticut, Illinois, Indiana, Iowa, Maine, Massachusetts, and Pennsylvania—7.

For these reasons and others the Commissioners from Massachusetts supported the proposition originally made by Kentucky, and introduced by Mr. Baldwin, of Connecticut, recommending a national convention for the purpose of revising the Constitution, and of providing for the exigencies likely to arise from the changed and perilous condition of the country. This measure offered an opportunity for consideration by the people, and for careful deliberation by the convention that might be constituted for the purpose. It is highly probable that, after the lapse of three-fourths of a century, a convention of delegates from all the States would by general consent propose amendments to the Constitution; and it is also probable that such a convention would at once tend to strengthen the feeling of brotherhood among the people of various sections, while the discussion of the principles of the Government would render its preservation of paramount concern to all. This measure of peace and union was rejected.

The undersigned are constrained by the force of many facts and circumstances to believe that an exciting cause of the present difficulties, and a serious obstacle to their removal, is the possible acquisition of Mexico and Central America.

The proceedings of the Convention furnish evidence upon this point.

The proposition to restore the Missouri Compromise, which guaranteed freedom north of the parallel 36° 30´ north latitude, but furnished no protection to slavery south of that line, was rejected by the aid of the unanimous support of the slaveholding States.

The proposition to settle the territorial question by the admission of New Mexico as a State, was summarily discouraged by the South in the committee.

The suggestion of one of the Commissioners from Massachusetts, that if the Convention would leave the territorial question out of view, the difficulties concerning the rights and relations of the existing States might be adjusted, did not meet with a favorable response from the slaveholding section of the country.

It is to be observed further, that the various propositions and amendments which were in any degree acceptable to the slave States guaranteed slavery south of said line.
