In his interpretation of the introduction of the calumet ceremony into
the southeastern U.S. in this journal, Brown (1989) has perpetuated a
common error that the lithic nickname ''catlinite'' correctly describ
es any of the red Plains pipestones from the three well-known midweste
rn localities he cites. In truth, the mineralogy of each of the pipe s
tones from those three geologic sources (provenances) are distinct fro
m one another, and that of catlinite is diagnostic. Although most of t
he artifacts he evaluates are probably true catlinite, many of them mi
ght not be. Unless archaeologists know of what material an object is m
ade, they do not know from where the material originated; thus they ca
nnot know who obtained the material nor how the artifact reached its a
rchaeological location (provenience).
