survived in the belt of vegetation that lined the valley at this point. Nor was a wall traceable farther on where this belt gradually narrowed and finally gave place to bare clay, furrowed by the wind into small Yardangs, 4 to 6 feet in height. But a conspicuous tower rising above a bend of the river higher up afforded guidance ; it was reached after a march of about five miles from the last tower and, like it, proved to be of ancient construction.

Of the chips of wood, 04-5, one retained faint traces of Chinese characters. Among the abundant fragments of Han pottery found at the foot of the tower, the pieces of a vessel, 014-17, may be mentioned on account of their greyish-brown mottled glaze. An enclosure, measuring 27 feet along its northern wall, which alone still rose a few feet above the ground, once adjoined the tower to the west. The refuse of straw and dung dug up here yielded no finds ; but a broken Wu-chu coin was picked up outside. A low mound of earth, without clear indication of fascines, was found forming a rough semicircle to the north of the tower and probably represents a small segment of the otherwise wholly effaced Limes agger.

and stood to a height of 21 feet. That it has been used as a watch-station and probably occupied for a long time was proved by the abundance of potsherds of Han type that thickly covered the ground near by, especially to the south. Here, too, a broken Wu-chu coin was found. A well-marked agger, about Io feet in height, passed round the eastern, northern, and western faces of the little Mesa at a distance varying from 32 to 36 feet. But no continuation of this mound to the east or west could be traced.

T. xLI. d, a conspicuous tower of stamped clay, rising within 3o yards of the river bank and facing the lower end of the village lands of Chiu-tao-kou on the bank opposite. Owing to wind-erosion which had undercut the clay soil to a depth of 4 feet at the northern foot of the tower, that side had fallen down in solid blocks of pisé. The other half of the tower still stood to a height of about 28 feet. Ancient pottery debris lay in plenty at its foot, and the fragment of a Wu-chu coin was picked up near by.
