I have been greatly interested in the fate of Juan Placido, the black revolutionist of Cuba, who was executed in Havana, as the alleged instigator and leader of an attempted revolt on the part of the slaves in that city and its neighborhood. Juan Placido was born a slave on the estate of Don Terribio de Castro. His father was an African, his mother a mulatto. His mistress treated him with great kindness, and taught him to read. When he was twelve years of age she died, and he fell into other and less compassionate hands. At the age of eighteen, on seeing his mother struck with a heavy whip, he for the first time turned upon his tormentors. To use his own words, "I felt the blow in my heart. To utter a loud cry, and from a downcast boy, with the timidity of one weak as a lamb, to become all at office like a raging lion, was a thing of a moment." He was, however, subdued, and the next morning, together with his mother, a tenderly nurtured and delicate woman, severely scourged. On seeing his mother rudely stripped and thrown down upon the ground, he at first with tears implored the overseer to spare her; but at the sound of the first blow, as it cut into her naked flesh, he sprang once more upon the ruffian, who, having superior strength, beat him until he was nearer dead than alive. After suffering all the vicissitudes of slavery,--hunger, nakedness, stripes; after bravely and nobly bearing up against that slow, dreadful process which reduces the man to a thing, the image of God to a piece of merchandise, until he had reached his thirty-eighth year, he was unexpectedly released from his bonds. Some literary gentlemen in Havana, into whose hands two or three pieces of his composition had fallen, struck with the vigor, spirit, and natural grace which they manifested, sought out the author, and raised a subscription to purchase his freedom. He came to Havana, and maintained himself by house-painting, and such other employments as his ingenuity and talents placed within his reach. He wrote several poems, which have been published in Spanish at Havana, and translated by Dr. Madden, under the title of _Poems by a Slave_. It is not too much to say of these poems that they will bear a comparison with most of the productions of modern Spanish literature. The style is bold, free, energetic. Some of the pieces are sportive and graceful; such is the address to _The Cucuya_, or Cuban firefly. This beautiful insect is sometimes fastened in tiny nets to the light dresses of the Cuban ladies, a custom to which the writer gallantly alludes in the following lines:--
