of the three horizontal
divisions of the nave the main arcading occupies approximately
three-sevenths of the total height of the wall, while the triforium and
clerestory each occupy about two-sevenths.

The three western bays are early English in date and style, but they
differ considerably from the typical early English of Salisbury; we
do not find the detached shafts of Purbeck marble, nor the central
cylindrical shaft; the bases, too, are rectangular, nor are there any
enriched mouldings with dog-tooth ornament. In the triforium in some cases
there are three, in other cases two subordinate arches, each with cusped
heads, and the wall space above these smaller arches and the comprising
one is pierced by a quatrefoil opening. The clerestory throughout the
nave, whether in the Early English bays to the west or the Norman bays to
the east, is of the same character, having three pointed arches in each
bay with a window on the outside of the middle one. A passage protected by
two iron rails runs right round the church at this level, and it is well
worth ascending to this passage, as from it a good idea of the height of
the church may be obtained. The clerestory of the transept and also that
of the choir bear a general likeness to that of the nave, but are of
earlier date, the arcading having semicircular and not pointed arches. The
illustrations will show how shafts run on the face of the arcading right
up from floor to roof. In the Norman part of the building the triforium is
very peculiar; generally speaking, there are two subordinate round-headed
arches, under the general round-headed comprising arch, but the tympanum
or space above the former is left open, and from the point where the two
smaller arches meet a shaft runs up to the centre of the main outer arch.
I do not know of any similar arrangement in any other church, and, as it
is a very peculiar one, hard to explain clearly in words, the reader
should carefully study the illustrations in which the triforium appears.
On the east side of the north arm of the transept a more elaborate
arrangement of one of the arches may be seen. Here there are three,
instead of two, subsidiary arches, which are interlaced, but here, also,
the shaft above them appears, though necessarily much reduced in height.
These shafts do not add to the beauty of the triforium, and they hardly
