In the immediate precincts, a delightful picture is presented from the Green Court, which was once the main outer court of the monastery. Here are noble trees and beautifully kept turf, at once in perfect harmony and agreeable contrast with the rugged walls of the weather-beaten cathedral: the quiet soft colouring of the ancient buildings and that look of cloistered seclusion only to be found in the peaceful nooks of cathedral cities are seen here at their very best. [Illustration: "BELL HARRY," THE CENTRAL TOWER.] The chief glory of the exterior of Canterbury Cathedral is the central #Angel or Bell Tower#. This is one of the most perfect structures that Gothic architecture, inspired by the loftiest purpose that ever stimulated the work of any art, has produced. It was completed by Prior Selling, who held office in 1472, and has been variously called the Bell Harry Tower from the mighty Dunstan bell, weighing three tons and three hundredweight, and the Angel Tower from the gilded figure of an angel poised on one of the pinnacles, which has long ago disappeared. The tower itself is of two stages, with two two-light windows in each stage; the windows are transomed in each face, and the lower tier is canopied; each angle is rounded off with an octagonal turret and the whole structure is a marvellous example of architectural harmony, and in every way a work of transcendent beauty. The two buttressing arches and the ornamental braces which support it were added at the end of the fifteenth century by Prior Goldstone, to whom the building of the whole tower is apparently attributed in the following quaint passage from a mediaeval authority: "He by the influence and help of those honourable men, Cardinal John Morton and Prior William Sellyng, erected and magnificently completed that lofty tower commonly called Angyll Stepyll in the midst of the church, between the choir and the nave--vaulted with a most beautiful vault, and with excellent and artistic workmanship in every part sculptured and gilt, with ample windows glazed and ironed. He also with great care and industry annexed to the columns which support the same tower two arches or vaults of stone work, curiously carved, and four smaller ones, to assist in sustaining the said tower" ("Ang. Sac." i. 147, translated by Professor Willis). The western front of the cathedral is flanked by two towers of great beauty; a point in which Mediaeval architecture has risen above that of all other ages is the skill which it displays in the use of towers of different heights, breaking the dull straight line of the roof and carrying the eye gradually up to the loftiest point of the building. Canterbury presents an excellent example of the beauty of this subordination of lower towers to the chief; we invite the visitor, when looking at the exterior, to compare it mentally, on the one hand, with the dull severity of the roof line of a Greek temple, and on the other, to
