had made its appearance at Newstead before the end of the first occupation. Of this we have an indication from the occurrence, in the ditch of the early fort, of the small globular pot (Déchelette, Type 67), a form which appears to belong to Lezoux, and no doubt other types are represented. An examination of the Plique collection at St. Germain-en-Laye makes evident the difficulty of distinguishing with certainty the forms of decoration employed by these two groups of potteries towards the end of the first century in the so-called transition period. It seems probable that at this time not a few designs must have been in common use in both. In Scotland, however, the interval which is known to have elapsed between the Agricolan and the Antonine invasions renders the presence of the so-called transition style as sure an indication of early date as a knowledge of the provenance of the ware. In the second of the two periods the pottery is mainly Arvernian, corresponding to Déchelette's third period of Lezoux, although one or two pieces can be recognised as imported from the Rhine, probably from Rheinzabern.
The chief assistance in the classification of the Newstead finds was derived from the excavation of the various pits and ditches. A brief summary of the nature of this evidence will make what follows clear. It may also be noted here that the more important results confirm in a great measure the deductions drawn from similar investigations on the Continent. The ditches of the early fort were effectually closed by the works of the later one. The heavy rampart of clay, and in places the wall, had been piled above them. Their contents were thus sealed up. From these ditches there was recovered a considerable number of fragments which can only date from the first occupation, and which formed an index to the whole early pottery of the fort. The outer system of ditches of the West Annexe belong to the same period, and they also contributed a few pieces, while a number of pits, situated for the most part within or at no great distance from the defences, yielded pottery of a very similar character. The shards from the overlapping ditch in front of the West Gate were likewise early, although it is beyond doubt that the ditch had formed part of the fortification of the second fort; and early pottery was found in association with later types in the large ditch on the west front. On the other hand, the inner system of ditches of the West Annexe, one of which ran right through the buildings at the Baths, produced only the later types of pottery. These were found also in the outlying ditch parallel with the east front, called above the
