tween. They were of normal
plan, with external buttresses, basement walls, and ventilating windows
(not shown on plan). The space between them, 15 feet wide, contained
marks of an oven or ovens (plan, B) and also some corn (plan, C) and may
have been at one time used for drying grain stored in the granaries; how
far it was roofed is doubtful. Building II, the Principia or Praetorium,
a structure of 68 x 76 feet, much resembled the Principia at Hardknot,
ten miles west of Ambleside, but possessed distinct features. As the
plan shows, it had an entrance from the east, the two usual courts (EF),
and the offices which usually face on to the inner court F. These
offices, however, were only three in number instead of five, unless
wooden partitions were used. Under the central office, the _sacellum_ of
the fort, where the standards and the altars for the official worship of
the garrison are thought to have been kept, our fort had, at A, a sunk
room or cellar, 6 feet square, entered by a stone stair. Such cellars
occur at Chesters, Aesica, and elsewhere and probably served as
strong-rooms for the regimental funds. At Chesters, the cellar had stone
vaulting; at Ambleside there is no sign of this, and timber may have
been used. In the northernmost room of the Principia some corn and
woodwork as of a bin were noted (plan, C). The inner court F seemed to
Mr. Collingwood to have been roofed; in its north end was a detached
room, such as occurs at Chesters, of unknown use, which accords rather
ill with a roof. In the colonnade round the outer court E were vestiges
of a hearth or oven (plan, B). Building III (70 x 80 feet) is that
usually called the commandant's house; it seems to show the normal plan
of rooms arranged round a cloister enclosing a tiny open space. In
buildings II and III, at D, traces were detected as of ditches and
walling belonging to a fort older and probably smaller than that
revealed by the excavation generally.

Small finds include coins of Faustina Iunior, Iulia Domna, and Valens,
Samian of about A.D. 80 and later, including one or two bits of German
Samian, a silver spoon, some glass, iron, and bronze objects, a leaden
basin (?), and seven more leaden sling-bullets. It now seems clear that
the fort was established about the time of Agricola (A.D. 80-5), though
perhaps in smaller dimensions than those now visible, and was held till
at least A.D. 365. Mr. Collingwood inclines to the view that it was
abandoned af
