ill line with the ends of the granaries found some years ago.
This, or something very like it, is what we should naturally expect. We
then obtain a structure measuring 81 x 112 feet, the latter dimension
including a verandah 8 feet wide. This again seems a reasonable result.
Ribchester was a large fort, about 6 acres, garrisoned by cavalry;
in a similar fort at Chesters, on Hadrian's Wall, the Principia measured
85 x 125 feet: in the 'North Camp' at Camelon, another fort of much the
same size (nearly 6 acres), they measured 92 x 120 feet.

[Footnote 2: I saw this verandah while open. The whole excavations at
Caersws yielded important results and it is more than regrettable that
no report of them has ever been issued.]

(xi) _Slack._ The excavation of the Roman fort at Slack, near
Huddersfield, noted in my report for 1913 (p. 14), was continued in 1914
by Mr. P. W. Dodd and Mr. A. M. Woodward, lecturers in Leeds University,
which is doing good work in the exploration of southern Yorkshire. The
defences of the fort, part of its central buildings (fig. 4, I-III), and
part of its other buildings (B-K) have now been attacked. The defences
consist of (1) a ditch 15 feet wide, possibly double on the north (more
exactly north-west) side and certainly absent on the southern two-thirds
of the east (north-east) side; (2) a berme, 8 feet wide; and (3) a
rampart 20-5 feet thick, built of turf and strengthened by a rough stone
base which is, however, only 8-10 feet wide. Of the four gates, three
(west, north, and east) have been examined; all are small and have
wooden gate-posts instead of masonry. On each side of the east gate,
which is the widest (15 ft.), the rampart is thought to thicken as if
for greater defence. The absence of a ditch on the southern two-thirds
of the east side may be connected with some paving outside the east gate
and also with a bath-house, partly explored in 1824 and 1865, outside
the south-east (east) corner; we may think that here was an annexe. The
central buildings, so far as uncovered, are of stone; the Principia
(III) perhaps had some wooden partitions. They are all ill-preserved and
call for no further comment. West of them, in the rear of the fort, the
excavators traced two long narrow wooden buildings (B, C), north of the
road from the west (south-west) gate to the back of the Principia; on
the other side of the road they found the ends of tw
