To the members of the religious Society of Friends, I would earnestly appeal. They have already done much to put away the evil of slavery in this country and Great Britain. The blessings of many who were ready to perish have rested upon them. But their faithful testimony must be still steadily upborne, for the great work is but begun. Let them not relax their exertions, nor be contented with a lifeless testimony, a formal protestation against the evil. Active, prayerful, unwearied exertion is needed for its overthrow. But above all, let them not aid in excusing and palliating it. Slavery has no redeeming qualities, no feature of benevolence, nothing pure, nothing peaceful, nothing just. Let them carefully keep themselves aloof from all societies and all schemes which have a tendency to excuse or overlook its crying iniquity. True to a doctrine founded on love and mercy, "peace on earth and good will to men," they should regard the suffering slave as their brother, and endeavor to "put their souls in his soul's stead." They may earnestly desire the civilization of Africa, but they cannot aid in building up the colony of Liberia so long as that colony leans for support upon the arm of military power; so long as it proselytes to Christianity under the muzzles of its cannon; and preaches the doctrines of Christ while practising those of Mahomet. When the Sierra Leone Company was formed in England, not a member of the Society of Friends could be prevailed upon to engage in it, because the colony was to be supplied with cannon and other military stores. Yet the Foreign Agent of the Liberia Colony Society, to which the same insurmountable objection exists, is a member of the Society of Friends, and I understand has been recently employed in providing gunpowder, etc., for the use of the colony. There must be an awakening on this subject; other Woolmans and other Benezets must arise and speak the truth with the meek love of James and the fervent sincerity of Paul.

To the women of America, whose sympathies know no distinction of cline, or sect, or color, the suffering slave is making a strong appeal. Oh, let it not be unheeded! for of those to whom much is given much will be required at the last dread tribunal; and never in the strongest terms of human eulogy was woman's influence overrated. Sisters, daughters, wives, and mothers, your influence is felt everywhere, at the fireside, and in the halls of legislation, surrounding, like the all-encircling atmosphere, brother and father, husband and son! And by your love of them, by every holy sympathy of your bosoms, by every mournful appeal which comes up to you from hearts whose sanctuary of affections has been made waste and desolate, you are called upon to exert it in the cause of redemption from wrong and outrage.

Let the patriot, the friend of liberty and the Union of the States, no longer shut his eyes to the great danger, the master-evil before which all others dwindle into insignificance. Our Union is tottering to its foundation, and slavery is the cause. Remove the evil. Dry up at their source the bitter waters. In vain you enact and abrogate your tariffs; in vain is individual sacrifice, or sectional concession. The accursed thing is with us, the stone of stumbling and the rock of offence remains. Drag, then, the Achan into light; and let national repentance atone for national sin.

The conflicting interests of free and slave labor furnish the only ground for fear in relation to the permanency of the Union. The line of separation between them is day by day growing broader and deeper; geographically and politically united, we are already, in a moral point of view, a divided people. But a few months ago we were on the very verge of civil war, a war of brothers, a war between the North and the South, between the slave-holder and the free laborer. The danger has been delayed for a time; this bolt has fallen without mortal injury to the Union, but the cloud from whence it came still hangs above us, reddening with the elements of destruction.

Recent events have furnished ample proof that the slave-holding interest is prepared to resist any legislation on the part of the general government which is supposed to have a tendency, directly or indirectly, to encourage and invigorate free labor; and that it is determined to charge upon its opposite interest the infliction of all those evils which necessarily attend its own operation, "the primeval curse of Omnipotence upon slavery."

We have already felt in too many instances the extreme difficulty of cherishing in one common course of national legislation the opposite interests of republican equality and feudal aristocracy and servitude. The truth is, we have undertaken a moral impossibility. These interests are from their nature irreconcilable. The one is based upon the pure principles of rational liberty; the other, under the name of freedom, revives the ancient European system of barons and villains, nobles and serfs. Indeed, the state of society which existed among our Anglo-Saxon ancestors was far more tolerable than that of many portions of our republican confederacy. For the Anglo-Saxon slaves had it in their power to purchase their freedom; and the laws of the realm recognized their liberation and placed them under legal protection.

(The diffusion of Christianity in Great Britain was moreover
followed by a general manumission; for it would seem that the
priests and missionaries of religion in that early and benighted age
were more faithful in the performance of their duties than those of
the present. "The holy fathers, monks, and friars," says Sir T.
Smith, "had in their confessions, and specially in their extreme and
deadly sickness, convinced the laity how dangerous a thing it was
for one Christian to hold another in bondage; so that temporal men,
by reason of the terror in their consciences, were glad to manumit
all their villains."—Hilt. Commonwealth, Blackstone, p. 52.)

To counteract the dangers resulting from a state of society so utterly at variance with the great Declaration of American freedom should be the earnest endeavor of every patriotic statesman. Nothing unconstitutional, nothing violent, should be attempted; but the true doctrine of the rights of man should be steadily kept in view; and the opposition to slavery should be inflexible and constantly maintained. The almost daily violations of the Constitution in consequence of the laws of some of the slave states, subjecting free colored citizens of New England and elsewhere, who may happen to be on board of our coasting vessels, to imprisonment immediately on their arrival in a Southern port should be provided against. Nor should the imprisonment of the free colored citizens of the Northern and Middle states, on suspicion of being runaways, subjecting them, even after being pronounced free, to the costs of their confinement and trial, be longer tolerated; for if we continue to yield to innovations like these upon the Constitution of our fathers, we shall erelong have the name only of a free government left us.

Dissemble as we may, it is impossible for us to believe, after fully considering the nature of slavery, that it can much longer maintain a peaceable existence among us. A day of revolution must come, and it is our duty to prepare for it. Its threatened evil may be changed into a national blessing. The establishment of schools for the instruction of the slave children, a general diffusion of the lights of Christianity, and the introduction of a sacred respect for the social obligations of marriage and for the relations between parents and children, among our black population, would render emancipation not only perfectly safe, but also of the highest advantage to the country. Two millions of freemen would be added to our population, upon whom in the hour of danger we could safely depend; "the domestic foe" would be changed into a firm friend, faithful, generous, and ready to encounter all dangers in our defence. It is well known that during the last war with Great Britain, wherever the enemy touched upon our Southern coast, the slaves in multitudes hastened to join them. On the other hand, the free blacks were highly serviceable in repelling them. So warm was the zeal of the latter, so manifest their courage in the defence of Louisiana, that the present Chief Magistrate of the United States publicly bestowed upon them one of the highest eulogiums ever offered by a commander to his soldiers.

Let no one seek an apology for silence on the subject of slavery because the laws of the land tolerate and sanction it. But a short time ago the slave-trade was protected by laws and treaties, and sanctioned by the example of men eminent for the reputation of piety and integrity. Yet public opinion broke over these barriers; it lifted the curtain and revealed the horrors of that most abominable traffic; and unrighteous law and ancient custom and avarice and luxury gave way before its irresistible authority. It should never be forgotten that human law cannot change the nature of human action in the pure eye of infinite justice; and that the ordinances of man cannot annul those of God. The slave system, as existing in this country, can be considered in no other light than as the cause of which the foul traffic in human flesh is the legitimate consequence. It is the parent, the fosterer, the sole supporter of the slave-trade. It creates the demand for slaves, and the foreign supply will always be equal to the demand of consumption. It keeps the market open. It offers inducements to the slave-trader which no severity of law against his traffic can overcome. By our laws his trade is piracy; while slavery, to which alone it owes its existence, is protected and cherished, and those engaged in it are rewarded by an increase of political power proportioned to the increase of their stock of human beings! To steal the natives of Africa is a crime worthy of an ignominious death; but to steal and enslave annually nearly one hundred thousand of the descendants of these stolen natives, born in this country, is considered altogether excusable and proper! For my own part, I know no difference between robbery in Africa and robbery at home. I could with as quiet a conscience engage in the one as the other.
