In the first of these the deep jambs of the opening are clearly defined, but in the other two only low mounds of débris suggest the gateway. In the ancient Cibolan pueblos, including those on the mesa of Tâaaiyalana, no remains of external gateways have been found; the plans suggest that the disposition of the various clusters approximated somewhat the irregular arrangement of the present day. There are only occasional traces, as of a continuous defensive outer wall, such as those seen at Nutria and Pescado. In the pueblos of the Cibola group, ancient and modern, access to the inner portion of the pueblo was usually afforded at a number of points. In the pueblo of Kin-tiel, however, occurs an excellent example of the defensive gateway. The jambs and corners of the opening are finished with great neatness, as may be seen in the illustration (Pl. CIII). This gateway or passage was roofed over, and the rectangular depressions for the reception of cross-beams still contain short stumps, protected from destruction by the masonry. The masonry over the passageway in falling carried away part of the masonry above the jamb corner, thus indicating continuity of bond. The ground plan of this ruin (Pl. LXIII) indicates clearly the various points at which access to the inner courts was obtained. On the east side a noticeable feature is the overlapping of the boundary wall of the south wing, forming an indirect entranceway. The remains do not indicate that this passage, like the one just described, was roofed over. In some cases the modern passageways, as they follow the jogs and angles of adjoining rows of houses, display similar changes of direction. In Shupaulovi, which preserves most distinctly in its plan the idea of the inclosed court, the passageway at the south end of the village changes its direction at a right angle before emerging into the court (Pl. XXX). This arrangement was undoubtedly determined by the position of the terraces long before the passageway was roofed over and built upon. Pl. XXII shows the south passageway of Walpi; the entrances are made narrower than the rest of the passage by building buttresses of masonry at the sides. This was probably done to secure the necessary support for the north and south walls of the upper story. One of the walls, as maybe seen in the illustration, rests directly upon a cross beam, strengthened in this manner.
