'Every motive which operates on the minds of slaveholders, tending to make the colonization of the free blacks an object of _interest_ to them, should operate in an equal degree to secure the hearty co-operation of the government of every slaveholding State.'--[African Repository, vol. vii. p. 176.] 'None are obliged to follow our example; AND THOSE WHO DO NOT, WILL FIND THE VALUE OF THEIR NEGROES INCREASED BY THE DEPARTURE OF OURS.'--[An advocate of colonization in the Western (Ky.) Luminary.] 'So far from its having a dangerous tendency, when properly considered, it will be viewed as AN ADDITIONAL GUARD TO OUR PECULIAR SPECIES OF PROPERTY.'--[An advocate of the Society in the New-Orleans Argus.] 'The slaveholder, who is in danger of having his slaves contaminated by their free friends of color, will not only be relieved from this danger, but THE VALUE OF HIS SLAVE WILL BE ENHANCED.'--[A new and interesting View of Slavery. By Humanitas, a colonization advocate. Baltimore, 1820.] It is perfectly obvious, that whatever tends to weaken and depress the present system, must render the holding of slaves less desirable, and the prospect of emancipation more auspicious. Cherishing this conviction, thousands of individuals in this country, and tens of thousands in Great Britain, are led by conscientious motives to abstain from the use of productions raised by slave labor, and to prefer those only which are the fruits of the toil of freemen. They believe in the soundness of the axiom, that 'the receiver is as bad as the thief;' and knowing that the slaves are held in bondage not on the ground of benevolence, or because their liberation would endanger the public safety, but _because they are profitable to their owners_, they also believe that the consumers of slave goods contribute to a fund for supporting slavery with all its abominations; that they are the Alpha and the Omega of the business; that the slave-trader, the slave-owner, and the slave-driver, are virtually the agents of the consumer, for by holding out the temptation, he is the original cause, the first mover in the horrid process; that we are imperiously called upon to refuse those articles of luxury, which are obtained at an absolute and lavish waste of the blood of our fellow men; that a merchant, who loads his vessel with the proceeds of slavery, does nearly as much in helping forward the slave trade, as he who loads his vessel in Africa with slaves--they are both twisting the same rope at different ends; that our patronage is putting an immense bribe into the hands of the slaveholders to kidnap, rob and oppress; that, were it not for this, they would be compelled by sheer necessity to liberate their slaves--for as soon as slave labor becomes unprofitable, the horrid system cannot be upheld.
