Like sudden nightfall over bloom and green The curtain dropped: and, momently, between The clank of fetter and the crack of thong, Half sob, half laughter, music swept along; A strange refrain, whose idle words and low, Like drunken mourners, kept the time of woe; As if the revellers at a masquerade Heard in the distance funeral marches played. Such music, dashing all his smiles with tears, The thoughtful voyager on Ponchartrain hears, Where, through the noonday dusk of wooded shores The negro boatman, singing to his oars, With a wild pathos borrowed of his wrong Redeems the jargon of his senseless song. "Look," said the Showman, sternly, as he rolled His curtain upward. "Fate's reverse behold!" A village straggling in loose disarray Of vulgar newness, premature decay; A tavern, crazy with its whiskey brawls, With "Slaves at Auction!" garnishing its walls; Without, surrounded by a motley crowd, The shrewd-eyed salesman, garrulous and loud, A squire or colonel in his pride of place, Known at free fights, the caucus, and the race, Prompt to proclaim his honor without blot, And silence doubters with a ten-pace shot, Mingling the negro-driving bully's rant With pious phrase and democratic cant, Yet never scrupling, with a filthy jest, To sell the infant from its mother's breast, Break through all ties of wedlock, home, and kin, Yield shrinking girlhood up to graybeard sin; Sell all the virtues with his human stock, The Christian graces on his auction-block, And coolly count on shrewdest bargains driven In hearts regenerate, and in souls forgiven!
