Mutato nomine, de te Fabula narratur.--HOR. _Sat._ I. i. 69, 70. And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shall escape the judgment of God?--_Rom._ ii. 3. There are individuals in the United States who hold more of their fellow-creatures in slavery than either of the Barbary Powers.--HUMPHREYS, _Valedictory Discourse before the Cincinnati of Connecticut_, p. 34. This was another attempt to expose Slavery before a promiscuous audience at a time when the subject was too delicate to be treated directly. Mr. Sumner commenced in the course at Boston, and afterwards gave the substance of his Lecture before many of the Lyceums of Massachusetts. Professedly historical in character, and carefully avoiding any discussion of slavery in our country, it escaped "censure," although jealous defenders of compromise were disturbed. Others were pleased to find their sentiments against slavery represented in the lecture-room. It was easy to see, that, under the guise of condemning the slavery of whites, he condemned the slavery of blacks. While showing how the first came to prevail, he naturally exposed the origin of all slavery; nor does he for a moment lose sight of slavery among us, which is constantly present under an _alias_. The outrage is exhibited not only in its original wrong and oppression, but in the constant efforts against it by all civilized nations, sometimes by ransom, sometimes by war, ending at last in bloody overthrow. Conspiracies and escapes are described. At that time there was intense interest in fugitive slaves, which was gratified by the stories here introduced, showing how human sympathies attend all seeking freedom. Elsewhere, as well as here, the North Star had been a guide. It was common to doubt the hardships of slavery in our country; but there were persons who doubted the hardships of slavery in the Barbary States. Nothing more common among compromisers than to say that our slaves did not desire freedom, and that they were better off than free negroes; but there were persons, professing to know the condition of the Barbary States, who insisted that there were white slaves who left with regret, and that they were better off than free Christians there. Thus at each point is this historical lecture an argument against Slavery, and an answer to its defenders. LECTURE.
