The Senator further makes the broad charge, that abolitionists wish to enforce the unnatural system of amalgamation.  We deny the fact, and call on the Senator for proof.  The citizens of the free States, the petitioners against slavery, the abolitionists of the free States in favor of amalgamation!  No, sir!  If you want evidence of the fact, and reasoning in support of amalgamation, you must look into the slave States; it is there it spreads and flourishes from slave mothers, and presents all possible colors and complexions, from the jet black African to the scarcely to be distinguished white person.  Does any one need proof of this fact? let him take but a few turns through the streets of your capital, and observe those whom he shall meet, and he will be perfectly satisfied.  Amalgamation, indeed!  The charge is made with a very bad grace on the present occasion.  No, sir; it is not the negro woman, it is the slave and the contaminating influence of slavery that is the mother of amalgamation.  Does the gentleman want facts on this subject? let him look at the colored race in the free States; it is a rare occurrence there.  A colony of blacks, some three or four hundred, were settled, some fifteen or twenty years since, in the county of Brown, a few miles distant from my former residence in Ohio, and I was told by a person living near them, a country merchant with whom they dealt, when conversing with him on this very subject, he informed me he knew of but one instance of a mulatto child being born amongst them for the last fifteen years; and I venture the assertion, had this same colony been settled in a slave State, the cases of a like kind would have been far more numerous.  I repeat again, in the words of Dr. Channing, it is a slave country that reeks with licentiousness of this kind, and for proof I refer to the opinions of Judge Harper, of North Carolina, in his defence of southern slavery.

The Senator, as if fearing that he had made his charge too broad, and might fail in proof to sustain it, seems to stop short, and make the inquiry, where is the process of amalgamation to begin?  He had heard of no instance of the kind against abolitionists; they (the abolitionists) would begin it with the laboring class; and if I understand the Senator correctly, that abolitionism, by throwing together the white and the black laborers, would naturally produce this result.  Sir, I regret, I deplore, that such a charge should be made against the laboring class—­that class which tills the ground; and, in obedience to the decree of their Maker, eat their bread in the sweat of their face—­that class, as Mr. Jefferson says, if God has a chosen people on earth, they are those who thus labor.  This charge is calculated for effect, to induce the laboring class to believe, that if emancipation takes place, they will be, in the free States, reduced to the same condition as the colored laborer.  The reverse of that is the truth of the case.  It is the slaveholder NOW,
