We all know the results of slavery in Greece and Rome. Troy perished by her slaves in a single night; and as like causes always produce like effects, our obligations to our slaveholding brethren imperiously demand that we should urge on them, in the most earnest manner, the duty of immediately abolishing slavery as their only hope of safety,--the only means by which they can escape the just judgments of God. The safety of immediate emancipation has been proved by Buenos Ayres in 1816, Colombia in 1821, Guatemala in 1824, Peru and Chili in 1828, Mexico in 1829, and especially on the 1st of August, 1834, when 800,000 slaves were set free in a single day in the British West India Islands; and thus far, not a single life has been lost, not a drop of blood shed, in consequence of that beneficent and righteous act. The consequences of holding slaves in bondage, and refusing to emancipate them, have always been disastrous. In our present exemption from slavery in the Free States, we have no cause of boasting, but rather of deep humiliation. We are all involved in the guilt, and must share in the punishment, unless timely and thorough repentance avert the impending blow. To do this effectually, information must be spread, the spirit of inquiry aroused, the temple of God be purified, and "the book of law be read in the ears of all the people," that thus the gross mistakes and misapprehensions which everywhere exist on the subject of slavery and its abolition may be corrected. Of these mistakes, no one is more prevalent or more dangerous than the one just mentioned, that insurrection, rapine and bloodshed are the necessary consequences of immediate emancipation; and that the only way to avert the evils and the curse of slavery, is to continue in the sin for the present, promise future repentance, and in the meantime, whilst we are preparing to get ready to begin to repent, do every thing that in us lies to extinguish every good feeling, and cultivate and bring into action every bad feeling of the human heart. That such is the belief, and consequent practice, to an alarming extent, throughout our country, and that such a course is impolitic, because it is wicked and dangerous, because it is unjust, facts abundantly show.
