in which the merlons are of
great width in proportion to the embrasures--an early feature--and have
the usual cruciform piercings, so splayed at the back as to leave no
doubt that they were really intended for the use of archers. The three
gargoyles below have been renewed, and none of the gargoyles on choir or
transepts are earlier, perhaps, than the Decorated period.

=The Choir. North Side.=--Here the three westernmost bays of the aisle and
clearstorey respectively are Archbishop Roger's work. Two flat
pilaster-buttresses rise out of the slope of the plinth and run up the
aisle-wall, each terminating short of the parapet in two sets-off close
together. The level of the window-sills was the same here as in the
transept, but the string-course has been broken in the Decorated period
by the insertion of three slender windows, each having two lights with a
quatrefoil above. Above the windows comes the moulded string or cornice
continued from the transept, and above this the pierced merlons of the
Decorated battlement are again very broad in proportion to the
embrasures. Instead of being built up, the exposed arches of the
triforium have here been glazed. The clearstorey resembles that of the
transept, but the corbel table is surmounted here by a slope, on which
rest two large gargoyles (renewed), and instead of a Decorated
battlement there is a plain coping.

The last three bays of the clearstorey and the last two of the aisle are
Decorated work, probably of the end of the thirteenth century, and here
the level of the plinth is again lowered to suit the slope of the
ground. In the aisle the two bays are separated from the rest and from
each other by buttresses having a projection of 8 feet. Either of these
buttresses is crowned by a gable having a finial, and is surmounted by a
tall square pinnacle to receive the thrust of a flying buttress that
spans the aisle; and either pinnacle has its sides panelled and gabled,
a head at each corner, and five finials. The two last aisle-windows are
larger than those in the western bays, but have much the same tracery.
They have, however, a thick shaft worked on the stones of the jamb, and
a large keeled round on the edge of the arch, and there is no dripstone.
Below them is a small string-course, which is carried round the east
end. The string or cornice above them is made to match that on the
western portion of the aisle, but in the battlement the merlons are of
merely ordinary wid
