Following a well-paved causeway of some seven or eight feet wide, the flat stones of which have been worn smooth by countless generations of forgotten footsteps, we can perceive perfectly the ground plan of the houses on each side. In most cases Dr. Sarmento has excavated down to the stone-laid flooring of the houses inside, and to the base of the masonry outside; and it is possible to wander through the main lanes or streets of the town, crossing each other at right angles here and there, and interspersed by little circular paved open spaces, and to reconstruct in the mind’s eye the primitive life of this city of long ago. Here, for instance, just inside the wall by which we entered is a little square house, some twelve feet wide, containing two rough millstones, of which many have been found. The walls are of huge, rough stones, evidently taken as they came and fitted together with small stones where necessary to fill in interstices, the whole cemented together by some hard rubbly compost. Running past this building and through the town (in one or two cases, indeed, through the houses themselves) is one of the several stone water channels protected by low walls on each side, and supplied in ancient times by the springs that still gush out plentifully on the hillside. Some of the houses are much larger, and must have contained two or more apartments. But what strikes the eye of the observer most is the relatively large number of purely circular edifices, and this it is that has mainly attracted the speculations of archæologists. Mr. Oswald Crawford, who went over the place whilst the excavations were in their earlier stages many years ago, was mistaken in his estimate that the round buildings were eight or nine times more numerous than the square, and he founded upon this and other data the opinion that the whole place was a great granary, where the food of the tribes might be stored in safety. So far from the round houses being eight times as numerous as the square, found at least four square houses to every one round; but that which struck me as most curious, and so far as I could learn, it had not specially attracted the attention of previous visitors, was that in a large number of cases the round houses were enclosed in a square or angular walled space, not very much larger than the circle, but leaving a passage of some two feet wide, in most cases on the right-hand side, between the two walls, leading to a space at the back between the circular wall and the wall of the square enclosure, the left-hand side of the circular wall being mostly built to touch the square wall on that side. Dr. Sarmento was of opinion that the space thus formed was for the purpose of sheltering cattle and domestic animals, and says that he had found some rough stone excavations like troughs in them, with, in one or two cases, a ring in the wall as if to tether beasts. The width of the entrance passage and the extent of the enclosed space in the rear of the
