Mr. MANN. May it please your honor, while nothing, on the one hand, will ever deter me from doing my duty to a client, yet, on the other hand, I am moved to say that I have been trained from my youth to such respect for a court of justice, that I would say nothing to it or before it which should not be fitting and appropriate, as apples of gold in pictures of silver. Let me then restate my argument, that we may see whether, and by whom, this rule has been departed from. I reiterate, then, if slaves are property, they are a peculiar kind of property. They are instinct with the common desires of humanity, and among them one of the deepest and strongest is the love of liberty. And just in proportion as their value is increased by intelligence and development, just in that proportion is the bond weakened by which they are held. In all places slaves hear something, but in this place they hear much, of what is said in behalf of human liberty and of human rights. If they hear this, and are above the condition of brutes, they will apply it to themselves. Every Fourth of July oration, if understood, is a torch to light up another St. Domingo. If they hear the word “_slave_” used in reference to those who have been deprived of their natural rights in other countries, they will apply that word to their own condition in this. If they hear the word “_tyrants_” used in reference to one who deprives others of their rights, for “_tyrants_” they will read “_masters_;” and no mortal power, or law, or art, can help it, but by blotting out all that is human within them. The slaves in this city are constantly hearing what must remind them that they are slaves; and therefore they are constantly incited to escape from their bondage. The torchlight procession, with its speeches and parade, was _one_ among ten thousand of these incitements. The slaves, therefore, who went on board the Pearl, might have obtained the idea of escape from some other person than from the prisoner,--from some orator who lays down rules for the meridian of Europe, which do not quite suit the meridian of America. Hence they might have gone and applied to the prisoner for a passage. To this he might have assented. And if so, then his offence can be nothing beyond the offence of “transporting,” and is not the offence of _stealing_, as charged in this indictment. And, as to the inflammatory language which the court charges me with having used: every word which was uttered by me, and which the court characterizes and denounces as “inflammatory,” and thinks not proper to be spoken in this court room, because it may endanger the institutions of this city, was the exact language of the Hon. Mr. Foote, senator in Congress from the State of Mississippi, uttered by him from the rostrum, on Pennsylvania Avenue, the most public place in this city, on the evening of the 13th of April last, to thousands of people there assembled, men, women, children, negroes and all.
