the barrack buildings just described cannot possibly have belonged, the signs of occupation were much greater in the southern than in the northern half of the area. The Agricolan ditch north of the west gate yielded almost no relics. The same ditch on the south contained many fragments of pottery, pieces of leather, and metal objects which had been thrown into it. If, as seems probable, the cavalry of the garrison was stationed in the Retentura, we may see in the strigae here the quarters of the men, and in the long building (Block XIX) the stables for their horses, while the open space on the north would form a convenient barrack yard.
The Garrison
While the information obtained from the exact subdivision of the Newstead barrack blocks enables us to arrive at some approximate estimate of the size of the garrison, we are unable to speak definitely as to the troops which composed it. The absence of inscriptions is much to be regretted, for those found in the course of the recent excavations add little to what was already known from the discoveries of altars in the eighteenth and nineteenth centuries. Altogether, we have from the site three altars bearing dedications by G. ARRIUS DOMITIANUS,[1] centurion of the Twentieth Legion Valeria Victrix, three stones bearing the legion's cognizance, a boar, and one fragment of a tablet, which appears to refer to the same legion. We have also a dedication of an altar by AELIUS MARCUS,[2] decurion of the Augustan Ala of Vocontii, and another by L. MAXIMIVS GAETVLICVS,[3] who simply styles himself a centurion of a Legion, but who is no doubt identical with LVCIVS MAXIMIVS GAETVLICVS, a centurion of the Twentieth Legion, whose altar dedicated to Jupiter Dolichenus has been found at Aesica.[4] These dedications are all by individuals, and from none of them do we learn the precise capacity in which the dedicators were present at Newstead. Was G. ARRIUS DOMITIANUS, who is responsible for no less than three, or L. Maximius Gaetulicvs, in command of legionary troops? Or were either of them seconded to command a garrison of auxiliaries? Were these soldiers contemporaries? Or do their dedications date from different epochs of the fort's history? These are questions which so far we are unable to answer with confidence. The altar of G. ARRIUS DOMITIANUS, which was found in the pit in the Principia,
