We have noticed the social and moral condition of the free colored people, from the days of Franklin, to the projection of colonization. We have also glanced at the main facts in relation to the abolition warfare upon colonization, and its success in paralyzing the enterprise. This subject demands a more extended notice. The most serious injury from this hostility, sustained by the cause of colonization, was the prejudice created, in the minds of the more intelligent free colored men, against emigration to Liberia. The Colonization Society had expressed its belief in the natural equality of the blacks and whites; and that there were a sufficient number of educated, upright, free colored men, in the United States, to establish and sustain a Republic on the coast of Africa, "whose citizens, rising rapidly in the scale of existence, under the stimulants to noble effort by which they would be surrounded, might soon become equal to the people of Europe, or of European origin--so long their masters and oppressors." These were the sentiments of the first Report of the Colonization Society, and often repeated since. Its appeals were made to the moral and intelligent of the free colored people; and, with their co-operation, the success of its scheme was considered certain. But the very persons needed to lead the enterprise, were, mostly, persuaded to reject the proffered aid, and the society was left to prosecute its plans with such materials as offered. In consequence of this opposition, it was greatly embarrassed, and made less progress in its work of African redemption, than it must have done under other circumstances. Had three-fourths of its emigrants been the enlightened, free colored men of the country, a dozen Liberias might now gird the coast of Africa, where but one exists; and the slave trader be entirely excluded from its shores. Doubtless, a wise Providence has governed here, as in other human affairs, and may have permitted this result, to show how speedily even semi-civilized men can be elevated under American Protestant free institutions. The great body of emigrants to Liberia, and nearly all the leading men who have sprung up in the colony, and contributed most to the formation of the Republic, went out from the very midst of slavery; and yet, what encouraging results! It has been a sad mistake to oppose colonization, and thus to retard Africa's redemption!
