Fig. 3 is an incense burner of rare form derived from a bronze. It is a variation of the more usual "hill censer" (_po shan lu_) which has the same body with a cover in the form of hills as on Fig. 1. In this case the cover suggests a lotus flower in bud, and is surmounted by a duck. The whole is coated with an iridescent green glaze. A few choice specimens of green-glazed Han pottery in the S.T. Peters Collection includes a well-modelled duck, a handsome vase with mask handles and hexagonal base, and a good example of the "granary urn." The last is a grain jar which derives its form from a granary tower. In some instances the tiled roof of the tower is represented by tile-mouldings on the shoulder; but in this instance the form is entirely conventionalised into a cylindrical vase supported by three bear-shaped feet. The bear, an emblem of strength, is commonly employed in this capacity in Han art. Another ornamental form borrowed from a homely object is the model of a well-head, of cylindrical shape, with arched superstructure, in the centre of which a pulley-wheel is represented. The well bucket is usually added, resting on the edge of the well. [Illustration: Fig. 2 Fig. 1 Fig. 3 Plate 3.--Han Pottery. Fig. 1.--"Hill Jar" with brown glaze.

Height 30 inches. _Freer Collection._] Plate 4 illustrates a remarkable structure which seems to represent a fowling tower. Models of houses and shrines have been found frequently in Han tombs, showing most of the elements which are combined in this complex ornament. The structure of wooden beams and galleries and the roofs with their tubular tile-ridges, the formal ox-heads supporting the angles of the lower gallery, the ornamentation of combed lines, are all features which occur in architectural tomb ornaments of the Han period. Here we have apparently a sporting tower, with persons engaged in shooting with crossbows at the pigeons which tamely perch on the roof. The dead birds have fallen into the saucer-like stand below. This rare and curious specimen is made of green-glazed pottery, and measures about 30 inches in height.
