Nor are the apprehensions of those who dread the rapid increase of the negro, at all sustained by facts. That fear of a coming internecine war of races, in case the colored man is emancipated, which haunts some minds, has no foundation except in ignorance of the real facts. In no portion of our history has our colored population ever increased with a rapidity nearly so great as the white population. From 1790 to 1860 the colored population increased in the ratio of 1 to 5.86; and the white population in the ratio of 1 to 8.50. If we compare them for any shorter period, we shall always find that the white population increased the more rapidly of the two. From 1790 to 1808, we might perhaps expect to find it otherwise; for during that period the slave trade was in full activity, and tens of thousands of Africans were imported as articles of merchandise. But from 1790 to 1810, while the colored population increased in the ratio of 1 to 1.81, the white population increased in the ratio of 1 to 1.84, although during that period the white population of the country was very little increased by immigration. How it has happened that this point, which our tables of population make so entirely plain, has been so much misapprehended, and why the prevailing notions respecting it are so erroneous, is not easy to explain. The above estimate also reckons all half breeds as belonging to the colored population. (See De Bow's 'Compendium of the United States Census of 1850,' Tables 18, 42, and 71.) But this is not all. A careful examination of Tables 42 and 71 of the volume above referred to, will show that the increase of the colored race in freedom is certainly not half so great as in slavery. Indeed there is great reason to doubt whether our colored population has ever increased at all, except in slavery. From 1790 to 1800 the free colored population almost doubled, evidently by the emancipation of slaves; for during that period the slave population of Connecticut, Delaware, New Hampshire, New York, Pennsylvania, Rhode Island, and Vermont was greatly diminished, while that of New Jersey and Maryland was very little increased. In the last mentioned the increase of her slave population was only 21/2 per cent. in ten years, while the increase of her free colored population was 1431/2 per cent. in the same period. These figures leave no room for doubt that the rapid increase of the free colored population in all that decade was caused by the fact that the great mass of the people were honestly opposed to slavery, and therefore the work of emancipation went on with rapidity.
