Upon the string-course which runs along the wall unbroken by the buttresses there is in each bay a window with a circular head, flanked by single columns. A ring-like ornament is used as a decoration for one of the mouldings of the arch.
These windows, except the one above the doorway, are restorations. The doorway itself, which leads into the nave, is modern, imitated from the Norman window.
The Clerestory in each compartment has a window which differs from the aisle windows in having the billet as decoration of its outer moulding. The string-course at the spring of the round head runs without a break from one to the other.
There is also an unbroken corbel table above the windows, of very expressive, life-like heads, no two of which are alike.
North Transept.—The north window is Debased Gothic, the tracery of the previous window having been similar to that of the great east window, while the west window is early English.
The Tower, the latest part of the cathedral, was the work of Bishop Strickland early in the fifteenth century. He erected it upon the piers of the ancient Norman tower. Its height is not much over 100 feet, and is very disappointing, because in England "cathedral towers are apt to be good, and really make their mark" (Pater). In fact, it does not at all give the impression of being part of such an important building as a cathedral. This is caused by its having been rebuilt on the scale of the Norman nave, and not on that of the enlarged choir. It takes up only about two-thirds of the width of the choir, and to mask this defect a turret rising to the top of the third stage of the tower is introduced on the north side, and another turret is added at the north-east angle.
