nd have square tops with the abacus hollowed and
grooved. The arches differ from those in the transept only in that the
large moulding under the soffit is 'keeled,' and that the mouldings
which flank it are simple ridges. In the triforium the cusps visible in
the glazed sub-arches belong to some tracery which has been applied to
the back at a later period.

The treatment of the vaulting-shafts is very remarkable; indeed, nothing
is more instructive than the variety shown in the treatment of this
feature throughout Archbishop Roger's church, the different parts of
which are suggestive of nothing so much as of a series of architectural
experiments. Here, upon the capital of each column, rests a sort of
compound rectangular plinth, from which project three corbels, hollowed
underneath and having little blocks beneath their overhanging edge. From
this plinth and corbels springs a cluster of no less than five shafts,
which, by their united width, conceal the springing of the upper order
of the main arches. They are banded at the string-course below the
triforium, and end at the sill of the clearstorey in a compound capital,
of which the three central members are square, and the others round.
Upon this capital, apparently, stand the two adjoining shafts that carry
the thickening of the wall above the clearstorey, and here (but hidden
by the vaulting) stands also the original roof-shaft, and these three
are 'detached.' Thus the arrangement is in principle similar to that
adopted in the north transept, while at the same time the clustered
shafts are even more disproportionate here than there to the slight
burden they have to carry; indeed the effect is that of five shafts
diminishing to one. The vaulting hides a feature which is not found in
the transept, namely, a little lancet arch whose apex comes exactly
behind the roof-shaft in each bay.

Though the three eastern bays (still on the north side) are chiefly
Decorated, portions of Archbishop Roger's work have been retained or
used again. Thus the fourth column from the west is his, and perhaps the
fifth up to the abacus, which is convex and of limestone. The respond
against the east wall is of his pattern, but it has not
