Compound vessels are rather rare, nearly all of the varieties being outlined in Fig. 428. Some of these are formed by uniting two or even three simple forms in one. Others are only partially compound and resemble the askoidal shapes of Greek art. Attention will be called to the probable origin of all these shapes elsewhere. [Illustration: FIG. 428.--Compound forms.] Life forms are found in all the groups of ware, but differ in the manner in which they are employed. Fig. 429 shows the usual methods of adapting the human form to high-necked bottles. Quadrupeds, fishes, and birds are treated in somewhat similar ways. The vessels represented in this and the four preceding illustrations belong to the various museums of the country. [Illustration: FIG. 429.--Adaptation of the human form.] ORNAMENT.--The styles of decoration are not distinct from those of other classes of vessels. The incised scroll patterns are sometimes very elaborate, and the designs in color are perhaps executed with greater care than in other groups. [Illustration: FIG. 430.--Bottle: Tennessee.--1/3.] [Illustration: FIG. 431.--Gourd-shaped vessel: Arkansas.--1/3. [_National Museum._]] ILLUSTRATIONS.--_Ordinary forms._--I have not thought it advisable to figure many specimens of plain bottles, as all the varieties of outline are repeated in the more highly elaborated or embellished pieces. Fig. 430 represents a plain bottle of the ordinary dark porous ware. The neck is narrow above and expands abruptly below. The body is globular. Looking at this vessel with reference to a possible origin, we observe its resemblance to a common form of gourd. By a review of the collection, we find that there are many similar vessels actually modeled in imitation of gourds. Good examples are given in the Third Annual Report of the Bureau of Ethnology, from which Fig. 431 is taken, and in a paper by Edward Evers in Contributions to the Archæology of Missouri. The markings of the original are often shown with a great deal of truthfulness in the earthenware reproductions. [Illustration: FIG. 432.--Bottle: Arkansas.--1/3.] [Illustration: FIG. 433.--Bottle: Arkansas.--1/3. [_National Museum._]] Quite distinct in outline from the preceding forms is the bottle shown in Fig. 432. The neck is high and cylindrical and the body resembles a slightly-flattened globe. Set about the shoulder are four medallion-like faces, the features of which are modeled roughly in low relief. The ware is of the ordinary dark, slightly polished variety.
