The _Choir_, which succeeded the Norman apsidal choir, was begun in 1200, and the Lady Chapel about 1300, when the choir was lengthened by one bay. Then the Early English choir was removed as far as the third pier east of the tower, and the present choir built in the Decorated style; the upper part of the three western bays was also removed, and a Decorated clerestory added. Thus we have the arches and piers of the first three bays Early English, clerestory Decorated, and three other bays Decorated. Wyatt wrought havoc here, but his plans have now been altered, and the arrangements been made to conform to the original design. It will be observed that the tracery of the clerestory windows is Perpendicular, inserted at the restoration after the siege; only one original being left. There is no triforium, there being only two storeys. The spandrels have cusped circles, and in the older part niches with statues: on south, SS. Christopher, James and Philip; and on north, SS. Peter, Mary Magdelene and the Virgin. The stalls and bishop's throne are modern. The _Reredos_ is very magnificent, designed by Sir G. Scott. The pavement contains a veritable history of the Cathedral, while the space before the altar contains Old Testament types of the sacrifice of our Lord. The canopies of the _Sedilia_ are ancient and Late Decorated. The _Choir Aisles_ resemble in style the parts of the choir to which they are adjacent. In the north there is Chantrey's monument of Bishop Ryder, and G.F. Watts's effigy of Bishop Lonsdale (d. 1867). The _Lady Chapel_ is full of interest, and especially noticeable is the stained glass of sixteenth century, brought from the destroyed Abbey of Herckenrode, having been concealed from the destructive zeal of French revolutionists. The subjects are scenes from the life of our Lord and figures of the benefactors of the Abbey, and are the work of Lambert Lombard, the first, and by far the best, of the Italianised Flemish School of the sixteenth century. The architecture of the chapel was begun by Bishop Langton (1296-1321), and finished by Northburg; the style is Decorated. It has an octagonal apse--an unique arrangement. Beneath the windows is an arcade, resting on a stone bench, and between the windows are niches, which have recently been filled with statues of excellent execution. These are:--St. Werburgh, St. Cecilia, St. Prisca, St. Faith, St. Catherine, St. Margaret, St. Lucy, St. Agnes, St. Ethelreda. The triptych which forms the reredos was carved at Ober Ammergau. The altar rails are of alabaster. Looking back we have a good view of the Cathedral, and note the considerable inclination of the choir. On the south side are the so-called mortuary chapels, which have been restored in memory of Bishop Selwyn, and contain his effigy and some mural paintings recording scenes from the adventurous life of this great missionary-bishop, who did so much to plant the Church in Melanesia. The shrine of St. Chad formerly stood
