It is very true, that in that portion of the Union where the labor of the negro race was found to be unsuited to the climate and unprofitable to the master, but few slaves were held at the time of the Declaration of Independence; and when the Constitution was adopted, it had entirely worn out in one of them, and measures had been taken for its gradual abolition in several others. But this change had not been produced by any change of opinion in relation to this race; but because it was discovered, from experience, that slave labor was unsuited to the climate and productions of these States: for some of the States, where it had ceased or nearly ceased to exist, were actively engaged in the slave trade, procuring cargoes on the coast of Africa, and transporting them for sale to those parts of the Union where their labor was found to be profitable, and suited to the climate and productions. And this traffic was openly carried on, and fortunes accumulated by it, without reproach from the people of the States where they resided. And it can hardly be supposed that, in the States where it was then countenanced in its worst form—that is, in the seizure and transportation—the people could have regarded those who were emancipated as entitled to equal rights with themselves.

And we may here again refer, in support of this proposition, to the plain and unequivocal language of the laws of the several States, some passed after the Declaration of Independence and before the Constitution was adopted, and some since the Government went into operation.

We need not refer, on this point, particularly to the laws of the present slaveholding States. Their statute books are full of provisions in relation to this class, in the same spirit with the Maryland law which we have before quoted. They have continued to treat them as an inferior class, and to subject them to strict police regulations, drawing a broad line of distinction between the citizen and the slave races, and legislating in relation to them upon the same principle which prevailed at the time of the Declaration of Independence. As relates to these States, it is too plain for argument, that they have never been regarded as a part of the people or citizens of the State, nor supposed to possess any political rights which the dominant race might not withhold or grant at their pleasure. And as long ago as 1822, the Court of Appeals of Kentucky decided that free negroes and mulattoes were not citizens within the meaning of the Constitution of the United States; and the correctness of this decision is recognised, and the same doctrine affirmed, in 1 Meigs's Tenn. Reports, 331.

And if we turn to the legislation of the States where slavery had worn out, or measures taken for its speedy abolition, we shall find the same opinions and principles equally fixed and equally acted upon.

Thus, Massachusetts, in 1786, passed a law similar to the colonial one of which we have spoken. The law of 1786, like the law of 1705, forbids the marriage of any white person with any negro, Indian, or mulatto, and inflicts a penalty of fifty pounds upon any one who shall join them in marriage; and declares all such marriages absolutely null and void, and degrades thus the unhappy issue of the marriage by fixing upon it the stain of bastardy. And this mark of degradation was renewed, and again impressed upon the race, in the careful and deliberate preparation of their revised code published in 1836. This code forbids any person from joining in marriage any white person with any Indian, negro, or mulatto, and subjects the party who shall offend in this respect, to imprisonment, not exceeding six months, in the common jail, or to hard labor, and to a fine of not less than fifty nor more than two hundred dollars; and, like the law of 1786, it declares the marriage to be absolutely null and void. It will be seen that the punishment is increased by the code upon the person who shall marry them, by adding imprisonment to a pecuniary penalty.

So, too, in Connecticut. We refer more particularly to the legislation of this State, because it was not only among the first to put an end to slavery within its own territory, but was the first to fix a mark of reprobation upon the African slave trade. The law last mentioned was passed in October, 1788, about nine months after the State had ratified and adopted the present Constitution of the United States; and by that law it prohibited its own citizens, under severe penalties, from engaging in the trade, and declared all policies of insurance on the vessel or cargo made in the State to be null and void. But, up to the time of the adoption of the Constitution, there is nothing in the legislation of the State indicating any change of opinion as to the relative rights and position of the white and black races in this country, or indicating that it meant to place the latter, when free, upon a level with its citizens. And certainly nothing which would have led the slaveholding States to suppose, that Connecticut designed to claim for them, under the new Constitution, the equal rights and privileges and rank of citizens in every other State.

The first step taken by Connecticut upon this subject was as early as 1774, when it passed an act forbidding the further importation of slaves into the State. But the section containing the prohibition is introduced by the following preamble:

"And whereas the increase of slaves in this state is injurious to the poor, and inconvenient."

This recital would appear to have been carefully introduced, in order to prevent any misunderstanding of the motive which induced the Legislature to pass the law, and places it distinctly upon the interest and convenience of the white population—excluding the inference that it might have been intended in any degree for the benefit of the other.

And in the act of 1784, by which the issue of slaves, born after the time therein mentioned, were to be free at a certain age, the section is again introduced by a preamble assigning similar motive for the act. It is in these words:
