ter A.D. 85 and reoccupied under or about the time of
Hadrian. The stratification of the turrets seems to show that it was
destroyed once or twice in the second or third centuries, but the
evidence is not wholly clear in details. The granaries seem to have been
rebuilt once and the rooms of the commandant's house mostly have two
floors.

(ix) _Lancaster._ In October and November 1914, structural remains
thought to be Roman, including 'an old Roman fireplace, circular in
shape, with stone flues branching out', were noted in the garden of St.
Mary's vicarage. The real meaning of the find seems doubtful.

(x) _Ribchester._ In the spring of 1913 a small school-building was
pulled down at Ribchester, and the Manchester Classical Association was
able to resume its examination of the Principia (praetorium) of the
Roman fort, above a part of which this building had stood. The work was
carried out by Prof. W. B. Anderson, of Manchester University, and Mr.
D. Atkinson, Research Fellow of Reading College, and, though limited in
extent, was very successful.

The first discovery of the Principia is due to Miss Greenall, who about
1905 was building a house close to the school and took care that certain
remains found by her builders should be duly noted: excavations in
1906-7, however, left the size and extent of these remains somewhat
uncertain and resulted in what we now know to be an incorrect plan. The
work done last spring makes it plain (fig. 3) that the Principia
fronted--in normal fashion--the main street of the fort (gravel laid on
cobbles) running from the north to the south gate. But, abnormally, the
frontage was formed by a verandah or colonnade: the only parallel which
I can quote is from Caersws, where excavations in 1909 revealed a
similar verandah in front of the Principia[2]. Next to the verandah
stood the usual Outer Court with a colonnade round it and two wells in
it (one is the usual provision): the colonnade seemed to have been twice
rebuilt. Beyond that are fainter traces of the Inner Court which,
however, lies mostly underneath a churchyard: the only fairly clear
feature is a room (A on plan) which seems to have stood on the right
side of the Inner Court, as at Chesters and Ambleside (fig. 2, above).
Behind this, probably, stood the usual five office rooms. If we carry
the Principia about 20 feet further back, which would be a full
allowance for these rooms with their walling, the end of the whole
structure w
