Of the nine chapels surrounding the east end of the abbey, the most interesting are those of Edward the Confessor, beyond the altar, and of Henry VII., at the extreme eastern end. The shrine of King Edward above referred to occupies the centre of his chapel, and was formerly richly inlaid with mosaics and precious stones, which, however, have been carried off. Henry VII.'s Chapel is a fine specimen of the architecture of his time, and the monuments of Queens Elizabeth and Mary of Scotland are in the north and south aisles. In the south transept is the Poets' Corner, with monuments to all the great poets, and here, as well as in nave and choir and the north transept, are monuments of hundreds of illustrious Englishmen. In making these burials there is a sort of method observed. Chaucer's interment in the Poets' Corner in 1400 led the south transept to be devoted to literary men. The north transept is devoted to statesmen, the first distinguished burial there being the elder Pitt in 1778. The organ is on the north side of the nave, and here the eminent musicians repose. In the side chapels the chief nobles are buried, and in the chancel and its adjoining chapels the sovereigns. Isaac Newton in 1727 was the first scientist buried in the nave, and that part has since been devoted to scientific men and philanthropists. Probably the finest tomb in the abbey is that of the elder Pitt, which bears the 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 George II. and George III., Divine Providence exalted Great Britain to a height of prosperity and glory unknown to any former age." One of the finest of the stained-glass windows in the nave is the double memorial window in memory of the poets Herbert and Cowper, erected by an American, George W. Childs. George III. and the British sovereigns since his reign have their tombs at Windsor, preferring that noble castle for their last resting-place. Upon the east side of the abbey is St. Margaret's, the special church of the House of Commons. Its east window contains the celebrated stained-glass representation of the Crucifixion, painted in Holland, which General Monk buried to keep the Puritans from destroying. Sir Walter Raleigh is entombed here, and an American subscription has placed a stained-glass window in the church to his memory, inscribed with these lines by James Russell Lowell: "The New World's sons, from England's breasts we drew Such milk as bids remember whence we came. Proud of her past, wherefrom our present grew, This window we inscribe with Raleigh's name." THE TOWER OF LONDON.
