The subsequent collection of facts is presented to your notice, with the hope that they will have that effect which facts always have on every candid and ingenuous mind. They exhibit clearly the dangers to which slaveholders are always liable, as well as the safety of immediate emancipation. They furnish, in both cases, a rule which admits of no exception, as it is always dangerous to do wrong, and safe to do right. Please to examine carefully the whole account of the revolution in St. Domingo, beginning in March, 1790, and ending in 1802. That exhibits a different picture from that presented in a speech made at the Union-saving meeting lately held in Boston. A part of the truth may be so told as to have all the effect of a deliberate lie.

SLAVE INSURRECTIONS.

* *

And they said one to another, We are verily guilty concerning our brother, in that we saw the anguish of his soul when he besought us, and we would not hear; therefore is this distress come upon us.—Gen. 42:21.

Thus said the Lord my God, Feed the flock of the slaughter, whose pastors slay them, and hold themselves not guilty; and they that sell them say, Blessed be the Lord, for I am rich; and their own shepherds pity them not.—Zech. 11:4, 5.

He that stealeth a man, and selleth him, or if he be found in his hand, he shall surely be put to death.—Ex. 21:16.

The late invasion of Virginia by Capt. John Brown and his company has, with all its concomitant circumstances, excited more attention and aroused a more thorough spirit of inquiry on the subject of slavery, than was ever before known. As this is pre-eminently a moral question, and as there is no neutral ground in morals, all intelligent men must ultimately take sides. Every such man must either cherish and defend slavery, or oppose and condemn it, and his vote, if he is an honest man, must accord with his belief. On a question of so momentous importance, "Silence is crime." It demands and will have a thorough investigation, and all attempts to stifle discussion will only accelerate the triumph of the cause they were designed to crush. Thus the denunciation in Congress of Mr. Helper's book, which is in substance only an abstract of facts taken from the last census of the United States, has operated as an extensive advertisement, and will be the means of circulating thousands of copies, where, without such denunciation, it would never have been known. There is in the North, as well as the South, a class of men who act, apparently, on the supposition that those who foresee and foretell any calamity are as guilty as those who create it, and that the only way to obviate any impending danger is not to see it. Such persons not only refuse to see and hear themselves, but do what they can to keep their neighbors in like ignorance.

It has been truly said that "the power of slavery lies in the ignorance, the degradation, the servility of the slaves, and of the non-slaveholding whites of the South, and of the corresponding classes in the Free States. It is through this ignorance and servility that the slaveholders manage to dictate to ecclesiastical bodies, to have power to control pulpits, presses, Colleges, Theological Seminaries, and Missionary and Tract Societies." To keep the blacks and non-slaveholding whites in ignorance is, doubtless, the reason why such pains are taken in Congress to prevent the circulation of Helper's book at the South, which was compiled by a non-slaveholder for the special benefit of the men of his class. The population of the Free States is now about eighteen millions; of the Slave States, eight millions. The slaves number about four millions, who are held as property by only 347,545 persons, men, women and children. This number, small as it is, constituting about one sixth part of the United States, have thus far controlled the legislation of the country. How this power has been acquired is easily understood when we examine the false ideas respecting slavery which are everywhere prevalent; such as the weakness of the public conscience, in the absence of a practical and experimental knowledge of the truth of God's word—in the atheistic notion, prevailing even in the Church and in the ministry, that the unrighteous enactments of wicked me are paramount in authority to the commandments of the Great Jehovah. Hundreds of clergymen, in all parts of the Union, profess to believe that the Bible sanctions American slavery,—a system which, of necessity, cannot exist without a continual violation of every commandment of the Decalogue.

If the Bible sanctions slavery, (as many profess to believe,) why does not the God of the Bible sanction it? In other words, if slavery is sanctioned by the revealed will of God, why are not the dispensations of his providence in accordance with that will? Could it be fairly proved that slavery is in accordance with the will of God, it must necessarily follow that obedience to his will is not only highly advantageous, but perfectly safe; for, surely, no Christian can, for a moment, believe that the providence of God ever militates against the precepts of his word. As, however, the consequences of slavery have been, in all cases, when not averted by timely repentance, disastrous in the extreme, it is therefore undeniably evident that slavery is in direct opposition to the revealed will of God, and, consequently, that those who so violently oppose the abolition of slavery, for fear of supposed dangerous consequences, may truly be said "to know not what they do." The truth on this subject is so plain, and the facts so abundant, that he who runs may read, and know to a certainty the entire safety of immediate emancipation; and that danger arises from liberty withheld, and not from liberty granted. The general opinion seems to be, that the moment you proclaim "liberty to the captive," and make the slave a freeman, be the conditions and restrictions what they may, that moment you make him a vagabond, a thief, and a murderer, whom nothing will satisfy but the blood of those who had been so "fanatical and insane" as to treat him like a human being. Whence this opinion is derived, no one can tell; for it is in direct opposition to reason, common sense, the nature of the human mind, and is entirely unsustained by facts. Indeed, so far as the evidence of facts is concerned, the advocates of immediate abolition have a complete monopoly. All experience proves two things, viz., the entire safety of immediate emancipation, and that all danger has arisen from its indefinite postponement; for this is really the true definition of gradual emancipation.

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.
