The States were generally unwilling to surrender anything of their internal sovereignty. They claimed then as they claim now, full right and power to regulate their own domestic institutions in their own way, and were willing to surrender to the general government only such powers as were necessary to the complete efficiency of a Federal government in attaining the purposes of the Union. These were in the language of Alexander Hamilton: "The common defence of the members; the preservation of the public peace as well against internal convulsions as external attacks; the regulation of commerce with other nations and between the States; the superintendence of our intercourse, political and commercial, with foreign countries." The difficulty of obtaining a ratification of the Constitution by the people of the States, was not less than the difficulty of framing it in convention. Georgia, New Jersey and Delaware unanimously approved the Constitution. It was supported by large majorities in Pennsylvania, Connecticut, Maryland and South Carolina. It was carried in Massachusetts, New York and Virginia only by a small majority. North Carolina and Rhode Island were the last to adopt it, and the former at first rejected it. In the address of the convention to Congress on presenting the Constitution with the recommendation for its submission to and approval by the States, the convention say: "The Constitution which we now present, _is the result of a spirit of amity, and of that mutual deference and concession_ which the peculiarity of our political situation rendered indispensable." In these few words of the framers of the Constitution, expressing its reason or spirit, we find the true guide to its interpretation and administration. The spirit of compromise, so far as relates to the clashing views or conflicting interests of different States or sections of the Union, pervades the Constitution in every part, and especially is this the case in reference to the now all-absorbing question of negro slavery. What was the state of this institution at the adoption of the Constitution, and how did the Constitution deal with it? The first introduction of African slaves into the American colonies was in 1620. The total number imported by means of the African slave trade between 1715 and 1790, was about 300,000. When the Constitution was ratified in 1790, the total number of slaves in all the States and territories was near 700,000. All the States ratifying the Constitution, except Massachusetts, held slaves; Virginia the largest number--over 293,000; New Hampshire the smallest number--158. Even the granite hills of New Hampshire were not then free from the feet of bondmen.
