south transept clerestory
has billet ornament. Above this is a corbel table of heads and mouldings
which interferes with the upper window mouldings. The transept
compartments differ from those of the nave by the addition of a flat
buttress between each, which consequently breaks the continuity of the
corbel table.

As the side of the nave was covered by the conventual buildings it was
of plainer character than the north, and had no buttresses between the
windows.

The clerestory is exactly the same as on the north.

The foundations of the old west wall are behind one of the prebendary's
houses to the west of the nave.

The west end, as it stands at present, was restored by Mr. Christian.

A local sandstone was used in the construction of the building: grey, or
white in the Norman portion, and red in the other parts. This red
sandstone is not so good for exterior as for interior work, because it
is liable to perish by the action of the weather.

CHAPTER III

THE INTERIOR

The cathedral now consists of part of the original nave (the two eastern
bays only) with aisles; and north and south transepts without aisles,
but with a chapel on the east side of the south transept; the central
tower; and the choir with north and south aisles and ambulatory or
retro-choir.

The #Nave.#--Entering by the modern doorway on the north, we are at once
in the fragmentary nave, of Early Norman work. Its present length is
about 38 feet and width about 60 feet. In 1645 the Scots destroyed about
100 feet of the nave, and it has never been rebuilt. This mutilation has
had a serious effect upon the proportions of the building, and induces a
feeling of want of balance. The open timber roof, raised to the original
height, was substituted at the restoration for a flat ceiling which had
been put up at a previous "embellishment" of the cathedral. Bishop
Walkelin made use of similar roofs in Winchester Cathedral (1070-1097).

The triforium (1140-50) has in each compartment a semi-circular arch
entirely without ornament.

The clerestory consists of three arches supported by columns with carved
capitals; the centre arch, which is larger than the other, is lighted at
the back by a round-headed window.

We may say that the nave is

"propped
With pillars of prodigious girth."

They are massive circular columns nearly six feet in diameter, and
support
