Certainly it is just at this period (about 75-85 A.D.) that towns like Silchester, Bath, Caerwent, seem to take definite shape,[2] and civil judges (_legati iuridici_) were appointed, presumably to administer the justice more frequently required by the advancing civilization.[3] In A.D.85 it was thought safe to reduce the garrison by a legion and some auxiliaries.[4] Progress, however, was not maintained.

About 115-20, and again about 155-63 and 175-80, the northern part of the province was vexed by serious risings, and the civilian area was doubtless kept somewhat in disturbance.[5] Probably it was at some point in this period that the flourishing country town of Isurium (Aldborough), fifteen miles from York, had to shield itself by a stone wall and ditch.[6] [Footnote 1: Tac.

_Agr._ 21, quoted in note 3 to p.

13.] [Footnote 2: Silchester was plainly laid out in Roman fashion all at once on a definite street plan, and though some few of its houses may be older, the town as a whole seems to have taken its rise from this event.
The evidence of coins implies that the development of the place began in the Flavian period (_Athenaeum_, Dec.

15, 1904).
