Above the stratum of ruins of the Fourth City there is a layer of débris about 6 ft. thick, evidently consisting of the remains of houses built of wood and clay. That the people of the fourth City, of which we see innumerable house-walls, should suddenly have abandoned the architecture they were accustomed to, and have built their houses of wood or mud, or of both conjoined, seems incredible. Besides, the rude stone hammers, which are found in such enormous quantities in the fourth city, are no longer found in this stratum; nor do the stone axes, which are so very abundant there, occur again here. Instead of the hundreds of axes I gathered in the fourth city, I collected in all only two here; but one of these—the axe of white jade represented under No. 1288—is, in the opinion of Mr. Story-Maskelyne, the most precious of all my thirteen Trojan jade axes, on account of its extreme rarity. I attribute it to this Fifth City, as it was found at a depth of only 6 ft. The saddle-querns of trachyte, which occurred in the fourth city by hundreds, were very rarely met with here. The forms of the terra-cotta whorls, too, are in innumerable instances different here.
