Roman Britain in 1914 | Page 5

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 will 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 × 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 × 125 feet: in the 'North Camp' at Camelon, another fort of much the same size (nearly 6 acres), they measured 92 × 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 two similar buildings (D, E). This looks as if this portion of the fort was filled with four barracks. On the other side of the row of buildings I-III remains were traced of stone structures; one of these (F) had the L-shape characteristic of barracks, and indications point to two others (G, H) of the same shape. This implies six barrack buildings in this portion of the fort and ten barrack buildings in all, that is, a cohort 1,000 strong. But the whole fort is only just 3 acres, and one would expect a smaller garrison; when excavations have advanced, we may perhaps find that the garrison was really a cohors quingenaria with six barracks, as at Gellygaer. Close against the east rampart, and indeed cutting somewhat into it, was a long thin building (K), 12-16 feet wide, which yielded much charcoal and potsherds and seemed an addition to the original plan of the fort.
