The differentiation in modern Cibolan and Tusayan symbolism is much greater than that of the ancient pottery from the same provinces, a fact which is believed to point to a similarity, possibly identity, of culture in ancient times. With this thought in mind, it would be highly instructive to study the ancient ruins of the Rio Grande region, as unfortunately no large collections of archeological objects from that part of the Southwest have been made.[86] The majority of the bowls from Awatobi are decorated in geometric patterns and a few have animal or human figures. The symbols, as well as the pottery itself, can not be distinguished from those of Sikyatki. Fragments of glazed ware are not unknown at Awatobi, but so far as recorded, entire specimens have never been obtained from the latter ruin. In order that the character of the geometric designs on Awatobi pottery may be better understood, two plates are introduced to illustrate their modifications in connection with my discussion of the geometric forms figured on Sikyatki ware. The figures on these bowls (plates CLXVI, CLXVII), with one or two exceptions, need no special description in addition to what is said of Sikyatki geometric designs, which they closely resemble. The cross-shape figure (plate CLXVI, _b_) may profitably be studied in connection with the account of the modification of Sikyatki sun symbols. Evidences of the use of a white pigment as a slip were found on one or two fragments of fine pottery from Awatobi, but no decoration of this kind was observed on the Sikyatki vessels. The red ware is the same as that found in ancient Cibola, while one or two fragments of glossy black recall the type common to modern Santa Clara. Two bird-shape vessels, one made of black-and-white ware, the other red with black-and-white decoration, were found at Awatobi. Large masses of clay suited to the potter's art were not uncommonly found in the corners of the rooms or in the niches in their walls. Some of these masses are of fine paste, the others coarse with grains of sand. The former variety was used in making the finest Tusayan ceramics; the latter was employed in modeling cooking pots and other vessels of ruder finish. Several flute-shape objects of clay, with flaring extremities, were found on the surface of the mounds of Awatobi, and one was taken from a Sikyatki grave. The use of these objects is unknown to me.
