Until the lands of America are appropriated by a few, population becomes dense, competition among laborers active, employment uncertain, and wages low, the personal liberty of all the whites will continue to be a blessing. We have vast unsettled territories; population may cease to increase, or increase slowly, as in most countries, and many centuries may elapse before the question will be practically suggested, whether slavery to capital be preferable to slavery to human masters. But the negro has neither energy nor enterprise, and, even in our sparser population, finds, with his improvident habits, that his liberty is a curse to himself, and a greater curse to the society around him. These considerations, and others equally obvious, have induced the South to attempt to defend negro slavery as an exceptional institution, admitting, nay asserting, that slavery, in the general or in the abstract, is morally wrong, and against common right. With singular inconsistency, after making this admission, which admits away the authority of the Bible, of profane history, and of the almost universal practice of mankind--they turn round and attempt to bolster up the cause of negro slavery by these very exploded authorities. If we mean not to repudiate all divine, and almost all human authority in favor of slavery, we must vindicate that institution in the abstract. To insist that a status of society, which has been almost universal, and which is expressly and continually justified by Holy Writ, is its natural, normal, and necessary status, under the ordinary circumstances, is on its face a plausible and probable proposition. To insist on less, is to yield our cause, and to give up our religion; for if white slavery be morally wrong, be a violation of natural rights, the Bible cannot be true. Human and divine authority do seem in the general to concur, in establishing the expediency of having masters and slaves of different races. The nominal servitude of the Jews to each other, in its temporary character, and no doubt in its mild character, more nearly resembled our wardship and apprenticeship, than ordinary domestic slavery. In very many nations of antiquity, and in some of modern times, the law has permitted the native citizens to become slaves to each other. But few take advantage of such laws; and the infrequency of the practice, establishes the general truth that master and slave should be of different national descent. In some respects, the wider the difference the better, as the slave will feel less mortified by his position. In other respects, it may be that too wide a difference hardens the hearts and brutalizes the feelings of both master and slave. The civilized man hates the savage, and the savage returns the hatred with interest. Hence, West India slavery, of newly caught negroes, is not a very humane, affectionate or civilizing institution. Virginia negroes have become moral and intelligent. They love their master and his family, and
