The Following 3 papers continue a series of brief articles on this subject appearing from time to time in American Antiquity (Vols. 17, 19). Each paper presents a group of raw data with some brief suggestions for their interpretation. All but one are the result of the study of materials recovered from archaeological sites excavated by the River Basin Surveys program of archaeological salvage in the Missouri Basin. That one (No. 6) dealt with an elk specimen from Michigan. Paper Number 1 was concerned with the analysis of the antelope bone from 2 sites in the Angostura Reservoir, South Dakota. Number 2 dealt with the bison bone from 2 earth-lodge villages sites in the Oahe Reservoir near Pierre, South Dakota. Number 3 compared the use of small and large animals as food in one site in the Garrison Reservoir, North Dakota. Number 4 was a comparison of the treatment of bison bone from 3 earth-lodge villages, 2 in Oahe Reservoir and one in Garrison Reservoir.
