The National Museum of Natural History, Smithsonian Institution (NMNH) has extensive collections of artifacts from ancestral Caddo sites in the Caddo area. This includes 19 ceramic vessels and one distinctive ceramic pipe from several sites in the upper Neches River basin in East Texas. The majority of these artifacts were originally collected by noted amateur archaeologist R. King Harris of Dallas, Texas, who sold his collection to the NMNH in 1980, while three of the vessels were originally in Bureau of American Ethnology holdings, and likely are from early archaeological investigations by Dr. J. E. Pearce of The University of Texas at Austin that were funded by the Bureau of American Ethnology (BAE). Pearce began work in this part of the state under the auspices of the BAE, and that work “had led me to suppose that I should find this part of the State rich in archeological material of a high order.
