During those years of sinful compromise the crime of man-robbery less atrocious than at present? Because the Constitution permitted, in that single crime, the violation of all the commandments of God, was that violation less terrible to earth or offensive to heaven?

No one now defends that "constitutional" slavetrade. Loaded with the curse of God and man, it stands amidst minor iniquities, like Satan in Pandemonium, preeminent and monstrous in crime.

And if the slave-trade has become thus odious, what must be the fate, erelong, of its parent, slavery? If the mere consequence be thus blackening under the execration of all the world, who shall measure the dreadful amount of infamy which must finally settle on the cause itself? The titled ecclesiastic and the ambitious statesman should have their warning on this point. They should know that public opinion is steadily turning to the light of truth. The fountains are breaking up around us, and the great deep will soon be in motion. A stern, uncompromising, and solemn spirit of inquiry is abroad. It cannot be arrested, and its result may be easily foreseen. It will not long be popular to talk of the legality of soul-murder, the constitutionality of man-robbery.

One word in relation to our duty to our Southern brethren. If we detest their system of slavery in our hearts, let us not play the hypocrite with our lips. Let us not pay so poor a compliment to their understandings as to suppose that we can deceive them into a compliance with our views of justice by ambiguous sophistry, and overcome their sinful practices and established prejudices by miserable stratagem. Let us not first do violence to our consciences by admitting their moral right to property in man, and then go to work like so many vagabond pedlers to cheat them out of it. They have a right to complain of such treatment. It is mean, and wicked, and dishonorable. Let us rather treat our Southern friends as intelligent and high-minded men, who, whatever may be their faults, despise unmanly artifice, and loathe cant, and abhor hypocrisy. Connected with them, not by political ties alone, but by common sacrifices and mutual benefits, let us seek to expostulate with them earnestly and openly, to gain at least their confidence in our sincerity, to appeal to their consciences, reason, and interests; and, using no other weapons than those of moral truth, contend fearlessly with the evil system they are cherishing. And if, in an immediate compliance with the strict demands of justice, they should need our aid and sympathy, let us open to them our hearts and our purses. But in the name of sincerity, and for the love of peace and the harmony of the Union, let there be no more mining and countermining, no more blending of apology with denunciation, no more Janus-like systems of reform, with one face for the South and another for the North.

If we steadily adhere to the principles upon which we have heretofore acted, if we present our naked hearts to the view of all, if we meet the threats and violence of our misguided enemies with the bare bosom and weaponless hand of innocence, may we not trust that the arm of our Heavenly Father will be under us, to strengthen and support us? And although we may not be able to save our country from the awful judgment she is provoking, though the pillars of the Union fall and all the elements of her greatness perish, still let it be our part to rally around the standard of truth and justice, to wash our hands of evil, to keep our own souls unspotted, and, bearing our testimony and lifting our warning voices to the last, leave the event in the hands of a righteous God.

JOHN QUINCY ADAMS.

In 1837 Isaac Knapp printed Letters from John Quincy Adams to his Constituents of the Twelfth Congressional District in Massachusetts, to which is added his Speech in Congress, delivered February 9, 1837, and the following stood as an introduction to the pamphlet.

THE following letters have been published, within a few weeks, in the Quincy (Mass.) 'Patriot'. Notwithstanding the great importance of the subjects which they discuss, the intense interest which they are calculated to awaken throughout this commonwealth and the whole country, and the exalted reputation of their author as a profound statesman and powerful writer, they are as yet hardly known beyond the limits of the constituency to whom they are particularly addressed. The reason of this is sufficiently obvious. John Quincy Adams belongs to neither of the prominent political parties, fights no partisan battles, and cannot be prevailed upon to sacrifice truth and principle upon the altar of party expediency and interest. Hence neither party is interested in defending his course, or in giving him an opportunity to defend himself. But however systematic may be the efforts of mere partisan presses to suppress and hold back from the public eye the powerful and triumphant vindication of the Right of Petition, the graphic delineation of the slavery spirit in Congress, and the humbling disclosure of Northern cowardice and treachery, contained in these letters, they are destined to exert a powerful influence upon the public mind. They will constitute one of the most striking pages in the history of our times. They will be read with avidity in the North and in the South, and throughout Europe. Apart from the interest excited by the subjects under discussion, and viewed only as literary productions, they may be ranked among the highest intellectual efforts of their author. Their sarcasm is Junius-like,— cold, keen, unsparing. In boldness, directness, and eloquent appeal, they will bear comparison with O'Connell's celebrated 'Letters to the Reformers of Great Britain'. They are the offspring of an intellect unshorn of its primal strength, and combining the ardor of youth with the experience of age.

The disclosure made in these letters of the slavery influence exerted in Congress over the representatives of the free states, of the manner in which the rights of freemen have been bartered for Southern votes, or basely yielded to the threats of men educated in despotism, and stamped by the free indulgence of unrestrained tyranny with the "odious peculiarities" of slavery, is painful and humiliating in the extreme. It will be seen that, in the great struggle for and against the Right of Petition, an account of which is given in the following pages, their author stood, in a great measure, alone and unsupported by his Northern colleagues. On his "gray, discrowned head" the entire fury of slave- holding arrogance and wrath was expended. He stood alone, beating back, with his aged and single arm, the tide which would have borne down and overwhelmed a less sturdy and determined spirit.

We need not solicit for these letters, and the speech which accompanies them, a thorough perusal. They deserve, and we trust will receive, a circulation throughout the entire country. They will meet a cordial welcome from every lover of human liberty, from every friend of justice and the rights of man, irrespective of color or condition. The principles which they defend, the sentiments which they express, are those of Massachusetts, as recently asserted, almost unanimously, by her legislature. In both branches of that body, during the discussion of the subject of slavery and the right of petition, the course of the ex- President was warmly and eloquently commended. Massachusetts will sustain her tried and faithful representative; and the time is not far distant when the best and worthiest citizens of the entire North will proffer him their thanks for his noble defence of their rights as freemen, and of the rights of the slave as a man.
