[67] At several places on the surfaces of projecting rocks forming the foundations of buildings may be noticed grooves where metates were sharpened. One or more of these occur at the entrance to the "street" in front of room 51. The foundation of a wall in one room was built directly upon one of these grooves, part of the groove being in sight, the rest covered with masonry. Near room 92 there are many of these grooves as well as small pits.
[68] The first description of "glazed" pottery in the Pueblo region is given by Castañeda (1540), who says: "Throughout this province [Tiguex] are found glazed pottery and vessels truly remarkable both in shape and execution." This has sometimes been interpreted to mean the glossy but unglazed pottery of Santa Clara. Glazed pottery was found by the writer in 1896 in ruins on the Little Colorado. It appears to be intrusive in the Arizona ruins.
[69] Food bowls with handles, so common to the ruins of northern Arizona, were not found at Cliff Palace.
[70] No curved lines are present in the many examples of decoration on the outside of food bowls from Sikyatki.
[71] Sikyatki ware is more closely related to that of the ancient Jemez and Pajarito subarea than to that made by the Snake clans when they lived at Tokónabi, their old home, or at Black Falls shortly before they arrived at Walpi. Careful study of ancient Walpi pottery made by the Bear clan before the arrival of the Snake clans shows great similarity to Sikyatki pottery, and the same holds regarding the ware from old Shongopovi.
[72] In the ruins found on the banks of the Little Colorado at Black Falls, the predominating influence, as shown by pottery symbols, has been from the north. It is known from legends that Wukóki was settled by clans from the north, the close likeness to the symbols of the San Juan valley supporting traditions still current at Walpi.
[73] A thorough comparative study of Pueblo pottery symbolism is much restricted on account of lack of material from all ceramic culture areas of the Southwest. It is likewise made difficult by a mixture of types produced by the migration of clans from one area to another. The subject is capable of scientific treatment, but at present is most difficult of analysis.
[74] The Hopi use large clay canteens for this purpose, no vessels resembling which, whole or in fragments, have been found at Cliff Palace.
