other; one impost has billet-mouldings as drawn, the other has 
none, but it is evidently unfinished, being only roughly blocked out 
in parts. The base mould consists of three simple ovolo mouldings. 
The eastern arch (B)is round and stilted like the other, but it is 
higher and has two orders of roll mouldings and triple grouped 
shafts on each jamb: the caps and bases have been much mutilated 
but the abacus is square, and the entire feature looks later than the 
western arch. The floor-line of the former was about 1ft. lower 
than that of the latter, and the nave floor 1ft. 8in. lower still, 
following the natural slope of the ground towards the Avon. 
At the ground level, in the north and south walls of the tower, 
are two small doorways with lintels and round arches above; both 
were built up until 1888 when the one on the south was opened 
out. They occupy a position midway between the west walls of the 
aisles and the quoin of another wall which has now disappeared (with 
the exception of slight fragments near the ground at D D) 9ft. 5in. 
westward ; these two walls were 2ft. thick, as were also two similar 
ones flanking the western arch, the remains of which have been 
converted into two buttresses. The quoins at the internal angles 
of the aisle walls and connecting them with the tower are similar 
in all respects to the latter, and show that an earlier wall stood 
where the west wall of each aisle does, or, at least occupied that 
part of its site immediately against the tower. All these indi- 
cations lead to the conclusion that the western arch and the north 
and south doorways opened into three buildings attached to these 
sides of the tower. The question arises “What were these adjuncts?” 
On the visit of the British Archeological Association in 1880 Mr. 
Loftus Brock, F.S8.A., propounded the theory that the tower was 
once a central one, the chancel, or apse, being on the site of the 
present nave, and the nave westward of the tower, with transepts, 
or chapels, at the north and south of the tower.1_ This view of the 
matter appears to have found favour with some of our own Members 
on their visit to the Church last year, To me, however, it seems 
incredible, and I will re-state the reasons given in my report on 
1 Wilts Arch Mag., vol. xix., p, 152.
