save only the regiments 'per lineam valli'; these last the compiler of the Notitia borrowed from the older order to disguise the loss of the Wall. Even this did not last. In 402 Stilicho had to summon troops to Italy for home defence--among them, Mr. Craster suggests, the Sixth Legion--and in 407 the remaining Roman soldiers, including the Second Legion, were taken to the continent by Constantine III. Every one who handles this difficult period must indulge in conjecture; Mr. Craster has, perhaps, indulged rather much. It might be simpler to connect the abandonment of the mile-castles--his stage 2--with the recorded troubles which called Constans to Britain in 343, rather than invent an unrecorded action by Constantine I. I hesitate also to assume for the period 369-83 an otherwise unknown frontier garrison, which has left no trace of itself. I feel still greater doubt respecting the years 383-99. Here Mr. Craster argues from coin-finds. No coins have been found on the line of the Wall which were minted later than 383, and none at Corbridge, Carlisle, and South Shields which were minted later than 395; therefore, he infers, the Wall was abandoned soon after 383, and the other sites soon after 395. This is too rigid an argument. It may be a mere accident that the Wall has as yet yielded no coin which was minted between 383 and 395. At Wroxeter, for example, two small hoards were found some years ago which had clearly been lost at the moment when the town was sacked. By these hoards we should be able to date the catastrophe. Now the latest coin in one hoard was minted in or before 377, and the latest in the other in or before 383. But newer finds show that Wroxeter was not destroyed at earliest till after 390. Again, as Mr. Craster himself says, the coining of Roman copper practically stopped in 395; after that year the older copper issues appear to have remained in use for many a long day. That is clear in Gaul, where coins later than 395 seem to be rare, although Roman armies and influences were present for another fifty years. When Mr. Craster states that 'archaeology gives no support to the theory that the Tyne-Solway line was held after 395', he might add that it gives equally little support to the theory that it was not held after 395.
