Spain, who gave the first impulse and royal sanction to the slave trade, still clings to her idolatry. It rests as a plague spot upon the faces of her people. A case lately ordered before the United States Supreme Court, by one of her subjects, and favored by President Van Buren, secured one of the most important decisions ever given in this Nation. I allude to the case of the Armistad, whose whole cargo of souls were emancipated on the high seas, by the heroism of the chieftain Joseph Cinque. He arose in the strength of his manhood, and slew the captain, and imprisoned the crew, as they were pursuing their course from Havanna to Matanzas. Being unacquainted with navigation, he commanded the seamen to steer towards the sun-rise, knowing that his native country was in the East. But the sky becoming cloudy, the traders directed the vessel towards the American coast, expecting to find favor and assistance from their fellow bandits and brother pirates in this country. But in this they were mistaken, for justice triumphed. When the woe-freighted bark neared our coast, and Cinque saw the star-spangled banner floating in the breeze, it was then that the hero addressed his despairing comrades, while a triumphant smile played upon his face, and said, “_Brothers, we would have conquered, but the sun was against us_.” A sentence more heroic was never uttered by an untutored savage. It may be asked, why did he despair when he saw the flag of our country? Here is the answer, and be not surprised at it. Because he had seen it waving protectively from the masts of slavers, when freedom owned him as her child, and when he breathed her spirit on his native hills. The slave trade is carried on briskly in the beautiful island of Cuba. A few years ago, I witnessed the landing of a cargo of slaves, fresh from the coast of Africa, in the port of Havanna, in the presence of the Governor, and under the shadow of the Moro Castle, one of the strongest fortifications of the world. Recently, a great sacrifice has been made in that Island to the Spirit of despotism, in the death of the Patriot and Poet, Placido. Freedom mourns over his early tomb. The waves of the Atlantic, of whose vastness and sublimity he had sung, chaunted his dirge as the tyrants hid him in the grave! Placido was a mulatto, a true Poet, and of course a Patriot. His noble soul was moved with pity as he saw his fellow men in chains. Born to feel, and to act, he made a bold attempt to effect a revolution, and failing in it, he fell a martyr to his principles. On the day previous to his death, he wrote the following lines, of which Coolridge or Montgomery would not have been ashamed. They present a blaze of poetic fire, intense and sublime:-- “O Liberty! I wait for thee, To break this chain, and dungeon bar; I hear thy voice calling me, Deep in the frozen North, afar, With voice like God’s, and vision like a star.
