pointed arches, while those of the second and fourth are round.
Above this again were tall wooden spires covered with lead. These were
removed about the year 1657, and towards the close of the eighteenth
century the present pinnacles and open parapets were added. At this
time, also, much of the surface of the towers was renewed.
The #Central Tower.#--The present central tower is noble in
proportion, and forms a fitting and harmonious summit to the whole
group. It must needs be of a very different character from the old
Norman tower, of which no trace now remains; and was most probably of
the usual type, low and square, and surmounted by a short pyramidal
spire. The existing structure may be attributed to Bishop Booth and
Prior Richard Bell, about 1474, when the letter previously quoted was
written. Externally the tower is divided into two storeys. The lower
portion contains, on each side, a pair of two-light windows, glazed,
each divided by a transom, and their heads having an ogee label
crocketed and finished with a tall finial also crocketed. Between and on
either side of these windows are panelled pilasters and brackets
carrying figures. The lower and upper stages are divided by a narrow
external gallery running round the tower, and protected by a pierced,
embattled parapet. This is known as the Bell Ringers' Gallery, and
certainly adds greatly to the effect of the tower as a whole. The upper
stage, which is much less lofty, has also two two-light windows on each
face, surmounted by crocketed ogee label mouldings and finials. These
lights are louvred. The whole is surmounted by a deep open-work parapet.
On each angle of the tower are two buttresses, which are decorated with
panelling and canopied and crocketed niches containing figures. The
interior of the tower or lantern is remarkable for the gallery which
runs round it, which is reached from the roofs of the nave and choir
transepts by doors. It rests on corbels, each alternate one being carved
with grotesque heads, and is protected by a parapet pierced in
quatrefoils. The four doorways are ogee-headed, with crockets and
finials. There is strong evidence in the construction of the present
tower that it was the original intention to surmount it by some other
erection, probably a spire. Each interior angle contains strong and
massive squinches which are of no constructive use at present, and must
have been originally inserted to carry some superstructure. The
