one employed;
and the towers W. of the Quantocks are, as a rule, inferior to those of
the centre and east of the county. Most have large external
stair-turrets (commonly at the N.E. or S.E. angle), which, when carried
above the parapet and surmounted by spirelets, add dignity to the
plainer structures, but which are less appropriate where the pinnacles
are sufficiently prominent and graceful to give of themselves an
adequate finish. In the case of some of the finest towers the staircase
is wisely suppressed before reaching the summit. In most instances the
tower is at the W. end, and is square; but a few churches have
octagonal towers, which are usually central (S. Petherton, Stoke St
Gregory, Doulting, N. Curry, Barrington). _Spires_ are comparatively
rare, but they occur at E. Brent, Congresbury, Bridgwater, Croscombe,
Yatton, Pitminster, Castle Cary, Frome, Worle, Whatley, Porlock.

The classification of Somerset Perp. towers has often been attempted,
perhaps most successfully by Dr F.J. Allen, with whom the late R.P.
Brereton was in general agreement. By these careful observers they are
grouped according to the number and character of the windows inserted
in each stage. Adopting their principle of classification, though
arranging the order of the classes rather differently, we should
separate the best towers (viz. those that have _two_ or more windows
_side by side_ on the W. front) into two main divisions, according as
(I.) perpendicular, (II.) horizontal lines predominate. The first
division (I.) has the windows of the belfry stage (_three_ or _two_ in
number) prolonged as panels into the stage below. The group is a small
one, but includes, perhaps, the finest towers in the county (Batcombe,
Evercreech, Wrington, St Cuthbert's, Wells). The second division (II.)
has the stages clearly marked off by string-courses or horizontal
tracery, and may be subdivided into subordinate classes according as
there are (i.) _three_ windows in _two_ tiers, the belfry and the stage
below (Mells, Leigh-on-Mendip, Ilminster); (ii.) _three_ windows in
_one_ tier (belfry) only (Bruton, Shepton, Cranmore, Winscombe,
Banwell, Weston Zoyland, etc.); (iii.) _two_ windows in _three_ tiers,
the belfry and two stages below (St Mary's, Taunton); (iv.) _two_ in
_two_ tiers, the belfry and one stage below (Chewton Mendip, St John's,
Glastonbury); (v.) _two_ in _one_ tier (belfry) only (St James',
Taunton, Bishop's Lydeard, N. Petherton, Staple F
