The tiger paces up and down Behind the black bars of the page, He pads on silent angry feet, His heart is smouldering with rage. Captive within the lines of type He seeks, and yet can never find, The world where he was free to range: He is the poet's furious mind. His are the unblinking eyes that stare Into the gold heart of the sun, He rakes the sky of stars and hunts The darkness down, and is not done. His was the world to roam, who now Is captive to the black-barred page. Reader, unlock the lines and face The splendid danger of his rage!
