For several years past, anti-slavery truth has been spreading, and in proportion as light has shone upon the "peculiar institution," exposing to the world its crimes and blood,--enstamping upon its frontlet, "THE SUM OF ALL VILLAINIES,"--has the wrath of the impious slaveholder been kindled, and his arm outstretched to strengthen the chain, and press closer the yoke upon the helpless slave, proving conclusively that he loves darkness because his deeds are evil. Nor is this all; he and his apologists will insolently tell you, that _you_ are the guilty ones who have tightened the bonds of the slave, increased his hardships, and blighted his prospect of freedom, by your mistaken kindness, in showing the slaveholder the enormity of his sin! Can this be so? Have we any direct influence over his human chattels? None. Then who is it that rivets the chain and increases the already heavy burden of the crushed slave, but he who has the power to do with him as he wills? He it is, who has been thrust, unwillingly perhaps, into sufficient light to show him his moral corruption, and the character of the sin he is daily committing; he it is, whose avarice and idleness induces to hold fast that which is to him a source of wealth,-- and by no means to allow the same light to fall in upon the darkened intellect of his slave property, lest his riches "take to themselves wings;" or, as may be more properly said, _take to themselves legs and run away_. What stronger proof can we ask in favor of our position, than the intolerant spirit of the South? If the system and practice of Slavery is a righteous one, instituted by an All-wise God, certainly no human power-- especially one so impotent and futile as the abolition power is said to be --can ever overthrow it. Why then are the mails so closely examined, and fines imposed on prohibited anti-slavery documents? Is it beyond their power to confute the arguments adduced, or are they fearful that a ray of Northern light may fall on the mind of some listening slave, and direct him to the depot of an under-ground railroad? Judge ye! What but this same fearful and intolerant spirit,--this over-bearing, boasting spirit, was it, that cowardly attacked a Christian Senator, while seated unsuspectingly at his desk, and felled him to the floor, bleeding and senseless? Was not the villainous blow which fell upon the honored head of CHARLES SUMNER, dealt by the infamous Brooks of South Carolina, aimed at the free speech of the entire North? Was it, think you, a personal enmity that the cowardly scoundrel had toward our worthy Northern Senator, which induced the attack? No, no. Brooks spake for the South, and boldly has it responded--Amen!
