Jackson._ The Right Hon. WILLIAM PITT, First Earl of Chatham. He is represented as speaking in the Houses of Parliament. At his feet are figures of Prudence and Fortitude; below is a figure of Britannia, with the trident supported by Earth and Ocean. On the base is the following inscription:--"Erected by the King and Parliament as a testimony to the virtues and ability of William Pitt, Earl of Chatham, during whose administration, in the reigns of Geo. II. and III., Divine Providence exalted Great Britain to a height of prosperity and glory unknown to any former age. Born November 15, 1708. Died May 11, 1778."--_Bacon, sculptor._ Lord ROBERT MANNERS, aged 24; Captain WILLIAM BAYNE, aged 50; Captain WILLIAM BLAIR, aged 41. Upon a rostral column decorated with the hulks of three seventy-four gun ships, Genius has hung three medallions, containing the portraits of the Captains. Neptune is sitting upon a sea-horse, pointing them out as examples for posterity to emulate, and worthy of being recorded in the annals of their country, to Britannia, whose majestic figure, accompanied with a resemblance of a lion, supporting a shield of the arms of Great Britain, is standing on the opposite side beholding them with a fixed countenance, expressive of sorrow; while Fame is standing upon the top of the column, with a wreath of laurel to crown Lord Robert Manners, Captains Bayne and Blair, who were mortally wounded in the course of the naval engagements under the command of Admiral Sir George Brydges Rodney, on the 9th and 12th of April, 1782. In memory of their services, the King and Parliament of Great Britain caused this monument to be erected.
