That the free negroes of the U. S. will be induced to go in large numbers to Liberia, if a quick and pleasant passage by steam vessels be provided, and suitable preparation be made for them on their arrival, by the Colonization Society, cannot admit of any doubt. The funds of that society, augmented probably twenty fold, will then be available, almost exclusively, for the comfortable establishment of the emigrants in their new homes—the expense of transportation chargeable to the society being merely nominal. It is estimated that there are no less than 500,000 free colored people in the several States, and that the annual increase therein of the black race is 70,000 per annum. With respect to slaves, who may hereafter be manumitted, no doubt such manumission will, almost in every instance, be upon the condition that the parties shall avail themselves of the opportunity of emigrating to Liberia. The committee do not propose that the emigrants should be landed in Liberia and then left to their own resources. Liberia is at present incapable of receiving and providing shelter, subsistence, and employment for any great number of emigrants who may land there in a state of destitution. It has been the practice, heretofore, for the Colonization Society to provide for the colonists, whom they have sent out, for 6 months after their arrival, and the cost of such provision has averaged $30 per head, in addition to the cost of transportation. A large amount of money will be required to settle the colonists in the first instance comfortably in their new homes. But there is no doubt, that if the Government establish the proposed line of steam ships, the people of the different States, and the State Legislatures, will at once turn their attention to the subject of colonization, and that large appropriations will be voted, and liberal collections made, in aid of that object. The State of Maryland has already appropriated and laid out $200,000 in this work, and the Legislature of Virginia has lately appropriated $40,000 per year for the same purpose. But these sums are insignificant in comparison to what may be expected, if the Government shall give its high sanction to the colonization of Africa, and provide the means of transportation by a line of steam ships. In that event, the whole mass of the people, north and south, who for the most part do not appreciate the rapid progress, and the high capabilities of Liberia, will quickly discover the vast importance of colonization, and will urge their representatives to adopt measures adequate to the exigency of the case and the magnitude of the enterprise.
