The masonry is rough and massive, and the water seems more green and more mysterious in the mediæval basin than in those of this practical nineteenth century. We went there late one April afternoon, and lingered long in the cool and cavernous places where the water is gathered together. As we came home we traced the course of the old aqueducts which have long since been abandoned. The springs to-day are carried underground in a sort of switch-back fashion over the sloping hillsides. But the ruins of the earlier conduit remain in their old places.
