Ancient Pottery of the Mississippi Valley / Fourth Annual Report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution, 1882-83, Government Printing Office, Washington, 1886, pages 361-436

The report examines ceramics from the Mississippi Valley, surveying distribution across Middle and Upper Mississippi and Gulf provinces, excavation contexts, chronology, construction, materials, forms, and uses. It classifies bowls, pots, various bottle and jar types, and uncommon eccentric and life-form vessels, illustrated by numerous examples, and discusses modifications such as handles, rim alterations, and relief, intaglio, impressed, and painted ornamentation with typical pigments and motifs. It notes a tendency toward grotesque and animal-shaped forms, technical methods of modeling and engraving, and regional stylistic differences, and concludes with a summary synthesizing form classification and origins of decorative ideas.
