ner, while the third is narrower,
but is also panelled. Various gargoyles project from the uppermost
string, which on the east side is not broken by the central pilaster. As
this string is higher than the corbel-table of the older sides, the
tower presents a very curious appearance when seen from the south-west
or north-east.[48] The battlements and pinnacles were perhaps first
added when the south and east sides were rebuilt, but in places they
have been much renewed. The stair-turret is surmounted by a hexagonal
stone cap, which is pierced with a spire-light and crowned by a finial;
and there is also a wooden polygonal bell-cote at the north-west corner
of the tower. At the north-east angle the Perpendicular masonry turns
the corner and enfolds the Transitional buttresses, where it stops with
a jagged edge. This unfinished work has a considerable projection from
the Transitional walling, the intention having been, perhaps, to correct
externally the obliquity in the ground plan of Roger's tower;[49] it is
also corbelled away at the bottom, probably to afford freer passage
along the parapet walk and to avoid the necessity of a squinch.
Originally the tower had perhaps a low pyramidal roof without a parapet,
and then came several successive spires. The last of these, which fell
in 1660, is said to have been 120 feet high from the top of the tower,
and its disappearance has surely done more than anything else to spoil
the external effect of the building.[50]

=The South Side of the Choir.=--Here the three westernmost bays are
Perpendicular and the others Decorated. The westernmost window is
smaller than the rest, and is of three lights, with the mullions carried
up through the head. The next two windows imitate in curvature their
Decorated neighbours, and are of four lights, with the central mullion
branching out to form two sub-arches, between which a foliated circle, a
feature not common in Perpendicular windows, is introduced into the
head. In the fourth bay the Decorated arch has been filled with
Perpendicular tracery, but the fifth and sixth windows remain in their
original beauty as on the north side, save that in the easternmost the
small circles have been mutilated and have lost their foliation. The two
flying buttresses resemble those on the north side, but from the points
where they meet the wall two pilasters run up into the parapet, which is
flush with them and is crowned by a plain coping, while beneath it is
