The duty of the United States to them, is the same exactly as we owe to our colored fellow-subjects in our slave colonies, viz. to obey God, by letting them go free, by placing them beneath wise and equitable laws, and by loving them all, and treating them like brethren; that is to say, the unquestionable duty of the people of the United States is to emancipate their 2,000,000 slaves, and to raise the 500,000 free colored people to that estimation in their native country which is due to them. But the American Colonization Society deliberately rejects both of these first great duties, and confines itself to the colonization in Africa of the free colored people. They say, in page 5, of their Thirteenth Report, "To abolition she could not look--and need not look." It "could do nothing in the slave States for the cause of humanity;" and in page 8, "Emancipation, with the liberty to remain on this side of the Atlantic, is but an act of dreamy madness." Now in thus deliberately letting the great crime of negro slavery alone; and in thus substituting a little restricted act of very dubious benevolence to a few, for the great and sacred duty of right which they owe to all,--they hurt the great cause of everlasting truth and love, in the following particulars: 1. By offering to the nation a hope, at which many of their best men seem eagerly grasping, of getting rid of the colored people abroad--they conduce more and more, as this hope prevails, to keep out of mind the superior, unalterable, and immediate duty of righting them at home. 2. By removing whatever number it be, from their native country, the number which remains must be diminished,--and the more the number which remains is diminished, the more helpless will they become--the less will be the hope of their ever recovering their own liberty--and the more and longer will they be trampled upon. 3. The more the people of the United States (and this is equally true of Great Britain) substitute a _half-way_ duty, difficult, expensive, and partial as it must be, and criminal as it unquestionably is--for the _whole_ duty which they owe their negro fellow-subjects, of putting them, before the law, upon a par with themselves--the less will they be likely to feel their sin in continuing to wrong them; and the less they feel their sin, the less likely will they be to repent of it, and to do their duty. 4. The greater the number of slaves transported, the greater will be the value of the labor of those who remain; the more valuable their labor is, the greater will be the temptation to over-labor them, and the more, of course, they will be oppressed.
