6. (Julia K. Murray, 1982) For a discussion of the tall ts'ung [cong] 琮 with segmented-band decor, a type found in the late Neolithic jade inventory in eastern China, see Folder Sheet F1916.410.
Unlike the other tall ts'ung [cong] 琮 with segmented decor in the Freer collection, the tsung [cong] 琮 F1917.368 does not exhibit the same slight taper in width from top to bottom. Furthermore, the incised circles that appear between the horizontal bands in each of the five registers are cut more deeply and prominently. For the present, it seems best to leave the dating unchanged rather than reattribute the piece to the Neolithic period along with the other ts'ung [cong] 琮.
