His best and noblest production is an ode To Cuba, written on the occasion of Dr. Madden's departure from the island, and presented to that gentleman. It was never published in Cuba, as its sentiments would have subjected the author to persecution. It breathes a lofty spirit of patriotism, and an indignant sense of the wrongs inflicted upon his race. Withal, it has something of the grandeur and stateliness of the old Spanish muse.

"Cuba!—of what avail that thou art fair,
Pearl of the Seas, the pride of the Antilles,
If thy poor sons have still to see thee share
The pangs of bondage and its thousand ills?
Of what avail the verdure of thy hills,
The purple bloom thy coffee-plain displays;
The cane's luxuriant growth, whose culture fills
More graves than famine, or the sword finds ways
To glut with victims calmly as it slays?

"Of what avail that thy clear streams abound
With precious ore, if wealth there's, none to buy
Thy children's rights, and not one grain is found
For Learning's shrine, or for the altar nigh
Of poor, forsaken, downcast Liberty?
Of what avail the riches of thy port,
Forests of masts and ships from every sea,
If Trade alone is free, and man, the sport
And spoil of Trade, bears wrongs of every sort?

"Cuba! O Cuba!—-when men call thee fair,
And rich, and beautiful, the Queen of Isles,
Star of the West, and Ocean's gem most rare,
Oh, say to those who mock thee with such wiles:
Take off these flowers; and view the lifeless spoils
Which wait the worm; behold their hues beneath
The pale, cold cheek; and seek for living smiles
Where Beauty lies not in the arms of Death,
And Bondage taints not with its poison breath!"

The disastrous result of the last rising of the slaves—in Cuba is well known. Betrayed, and driven into premature collision with their oppressors, the insurrectionists were speedily crushed into subjection. Placido was arrested, and after a long hearing was condemned to be executed, and consigned to the Chapel of the Condemned.

How far he was implicated in the insurrectionary movement it is now perhaps impossible to ascertain. The popular voice at Havana pronounced him its leader and projector, and as such he was condemned. His own bitter wrongs; the terrible recollections of his life of servitude; the sad condition of his relatives and race, exposed to scorn, contumely, and the heavy hand of violence; the impunity with which the most dreadful outrages upon the persons of slaves were inflicted,—acting upon a mind fully capable of appreciating the beauty and dignity of freedom,— furnished abundant incentives to an effort for the redemption of his race and the humiliation of his oppressors. The Heraldo, of Madrid speaks of him as "the celebrated poet, a man of great natural genius, and beloved and appreciated by the most respectable young men of Havana." It accuses him of wild and ambitious projects, and states that he was intended to be the chief of the black race after they had thrown off the yoke of bondage.

He was executed at Havana in the seventh month, 1844. According to the custom in Cuba with condemned criminals, he was conducted from prison to the Chapel of the Doomed. He passed thither with singular composure, amidst a great concourse of people, gracefully saluting his numerous acquaintances. The chapel was hung with black cloth, and dimly lighted. He was seated beside his coffin. Priests in long black robes stood around him, chanting in sepulchral voices the service of the dead. It is an ordeal under which the stoutest-hearted and most resolute have been found to sink. After enduring it for twenty-four hours he was led out to execution. He came forth calm and undismayed; holding a crucifix in his hand, he recited in a loud, clear voice a solemn prayer in verse, which he had composed amidst the horrors of the Chapel. The following is an imperfect rendering of a poem which thrilled the hearts of all who heard it:—

"God of unbounded love and power eternal,
To Thee I turn in darkness and despair!
Stretch forth Thine arm, and from the brow infernal
Of Calumny the veil of Justice tear;
And from the forehead of my honest fame
Pluck the world's brand of infamy and shame!

"O King of kings!—my fathers' God!—who only
Art strong to save, by whom is all controlled,
Who givest the sea its waves, the dark and lonely
Abyss of heaven its light, the North its cold,
The air its currents, the warm sun its beams,
Life to the flowers, and motion to the streams!

"All things obey Thee, dying or reviving
As thou commandest; all, apart from Thee,
From Thee alone their life and power deriving,
Sink and are lost in vast eternity!
Yet doth the void obey Thee; since from naught
This marvellous being by Thy hand was wrought.
