'Again the question is asked, is slavery never to disappear from the Union? This is a startling and momentous question, but the answer is easy and the proof is clear--_it will certainly disappear if Texas is reannexed to the Union_, not by abolition, but in spite of all its frenzy, slowly and gradually, by diffusion, as it has thus nearly receded from several of the more Northern of the slaveholding States, and as it will certainly continue more rapidly to recede by the reannexation of Texas, into _Mexico and Central and Southern America_. Providence * * * thus will open Texas as a safety-valve, into and through which slavery will slowly and gradually recede, and finally disappear into the boundless regions of Mexico, and Central and Southern America. Beyond the Del Norte _slavery will not pass_; not only because it is forbidden by law, but because the colored races there preponderate in the ratio of ten to one over the whites, and holding, as they do, the government and most of the offices in their own possession, they will never permit the enslavement of any portion of the colored race, which makes and executes the laws of the country. In Bradford's Atlas the facts are given as follows: 'Mexico, area 1,690,000 square miles; population eight millions, one sixth white, and all the rest Indians, Africans, Mulattoes, Zambos, and other colored races. Central America, area 186,000 square miles; population nearly two millions, one sixth white, and the rest Negroes, Zambos, and other colored races. South America, area 6,500,000 square miles; population fourteen millions, one million white, four millions Indians, and the remainder, being nine millions, blacks and other colored races. The outlet for our negro race through this vast region can never be opened but by the reannexation of Texas; but, in that event, there, in that extensive country, bordering on our negro population, and four times greater in area than the whole Union, with a sparse population of but three to the square mile, where nine tenths of the people are of the colored races--there, upon that fertile soil, and in that delicious climate, so admirably adapted to the negro race, as all experience has now clearly shown, the free black would find a home. There, also, as the _slaves_, in the lapse of time, from the density of population and other causes, are _emancipated_, they will disappear, from time to time, west of the Del Norte, and beyond the limits of the Union, and among a race of their own color will be diffused through this vast region, where they will not be a _degraded caste_, and where, as to climate and social and moral condition, and all the hopes and comforts of life, they can occupy, _amid equals_, a position they can never attain in any part of this Union.'
