The #Towers# are now similar. The upper stage of that on the north
is an imitation, as far as possible, of the same section of the other
tower which was built in the thirteenth century. In its third stage
some differences are introduced. The masonry of the new work is
executed so as to carry on the courses of the old stonework that
attach it to the rest of the front. The new work has followed the
custom of the older and better traditions of the stonemasons, in that
it has been left strictly as it was finished by the tool upon the
"banker." The natural and simple texture imparted by the action of
chiselling leaves a character upon the stonework similar to that of
the earlier work.

The upper portion of the new north-west tower [29] being copied from
that part of the old one to the south, it will be enough to describe
the original. But first it is necessary to notice the lower stage of
the southern tower. The buttressing on the south angle is of a later
date than the rest of this section of the tower. It has a low
weathered base. The central part of it has its projection at the base
reduced when it reaches its summit by means of three steep sloping
weatherings. There are also openings in the buttress for the staircase
windows. The two lower windows of the west front in this tower are not
placed in the same vertical line. This peculiarity has been followed
in the new tower. The upper of these two windows is pointed, and has
no label-mould. But the angle shafts that carry the arch have carved
capitals and square-moulded abaci. Above the head of the pointed
window the tower changes in character. The buttresses run up to the
top as broad, flat surfaces, except that the northern one is slightly
weathered twice. The coupled windows are more deeply recessed, having
