extremities at these places, I convinced myself that they belonged to a continuous building. It is partly excavated in the rock, which however sinks on approaching the east. The masonry of the side walls and vaulting resembles that in the gallery below the convent of the Daughters of Sion. The floor is also paved throughout the whole length, as far as I saw. Josephus[293] mentions that a subterranean communication existed between the Antonia and the east gate of the Temple; consequently for this and the other preceding reasons I firmly believe that I have placed the tower in the true position. I believe then that the barrack stands in the valley; that is, upon the ancient position of the Pool Struthium, which has been filled up, by the materials cast into it by order of Titus, in making the bank to support the Roman battering train, and by the ruins of the Antonia itself. Had the tower occupied this position, the only side properly defended would have been that towards the Temple, by the high face of rock, which in that case ought to shew traces of having been hewn away towards the north. What purpose could my 'Strato's tower' have then served, if it had passed through the basement of the Antonia? It would have been useless as a communication, because the tower itself would have done as well, and it is too deep in the ground and too small for a work of defence. The buildings on the east of the barrack, between it and the first passage leading up to the Temple, may belong either to the age of Saladin or of Solyman I.; the Arabs attribute them to the latter. They have been greatly altered within and without, and therefore do not present any distinctive features. Their foundations rest upon the rock, which on the south side is one or two feet below the level of the _Haram_, but on the north from 14 to 18 feet lower down, being at the bottom of the valley which I have already mentioned. On the left of the passage going up to the _Haram_ is a bath now disused, inside the buildings. During my examination of it I discovered the eastern conduit, which starts from inside the gallery. Its course from this place to the pool of Bethesda cannot be followed, as it is stopped up by rubbish; it is vaulted but not founded upon the rock.
