There are two other classes of articles made of clay, sometimes lightly fired but more often unbaked. These are human figurines and nipple-shaped objects believed to be cult objects with no utilitarian purpose. The figurines almost invariably represent human females. Faces are indistinct except for the nose, which, like the breasts, is clearly marked. Arms, if shown at all, are sketchily indicated. Legs are scarcely ever shown. Necklaces and pendants are indicated by punctures and incised lines. The nipple or funnel-shaped objects are hollow cornucopias, about two inches long, decorated with punctations. They are perforated at the base, which suggests that they were once tied to something, possibly masks or clothing. There are many theories as to the significance of these traits. It has been suggested that they may have come with the introduction of maize and may be connected with fertility rites. Pottery did not entirely supplant basketry and many fine baskets continued to be made. There was greater use of red and black designs than in the previous period. Sometimes these were woven in and sometimes they were painted. Sandals reached their highest level of development at this time. They were finely woven of apocynum string over a yucca cord warp. Fringing was abandoned, and the toe was marked by a crescent-shaped scallop. The heel was puckered. Soles were double with designs worked in colored cord in zones on the upper surface and raised designs on the underside produced by variations in weave or by knotting. Carrying bands continued to be very finely woven but twined bags degenerated. Fur blankets were still manufactured but the use of feather cord became progressively more common. Some blankets were made partially of fur cord and partially of feather cord. Strips of bird skin were no longer used exclusively in the manufacture of the latter type. Small downy feathers were employed, as well as heavier feathers from which the stiffer part of the quill had been removed. Much turkey plumage was utilized, and it is believed by some archaeologists that turkeys were domesticated at this time,[87] although others do not think that domestication took place until later. There is no agreement as to whether turkeys were kept to provide food. It is most generally believed that they were not eaten. At this time new varieties of corn were cultivated, which tended to be somewhat larger than the earlier forms, and the people’s diet was changed to some extent by the introduction of beans as a food crop. The addition of beans to the daily fare may have been quite important for it would increase the protein content of the diet. Such a crop also indicates a more settled life, for, while corn may be planted and then left for long periods of time, beans require almost constant attention.
