_Orientation._--In questioning the Tusayan on this subject Mr. Stephen was told that no attention to the cardinal points was observed in the plan, although the walls are spoken of according to the direction to which they most closely approximate. An examination of the village plans of the preceding chapters, however, will show a remarkable degree of uniformity in the directions of kivas which can scarcely be due to accident in rooms built on such widely differing sites. The intention seems to have been to arrange these ceremonial chambers approximately on the north and south line, though none of the examples approach the meridian very closely. Most of them face southeast, though some, particularly in Walpi, face west of south. In Walpi four of the five kivas are planned on a southwest and northeast line, following the general direction of the mesa edge, while the remaining one faces southeast. The difference in this last case may have been brought about by exigencies of the site on the mesa edge and the form of the cavity in which the kiva was built. Again at Hano and Sichumovi (Pls. XVI and XVIII) on the first mesa this uniformity of direction prevails, but, as the plans show, the kivas in these two villages are few in number. The two kivas of Shupaulovi will be seen (Pl. XXX) to have the same direction, viz, facing southeast. In Shumopavi (Pl. XXXIV) there are four kivas all facing southeast. In Mashongnavi, however (Pl. XXVI), the same uniformity does not prevail. Three of the kivas face south of east, and two others built in the edge of the rocky bench on the south side of the village face west of south. In the large village of Oraibi there is remarkable uniformity in the direction of the many kivas, there being a variation of only a few degrees in direction in the whole number of thirteen shown on the plan (Pl. XXXVI). But in the case of the large kiva partly above ground designated as the Coyote kiva, the direction from which it is entered is the reverse of that of the other kivas. No explanation is offered that will account for this curious single exception to the rule. The intention of the builders has evidently been to make the altar and its attendant structural features conform to a definite direction, fixed, perhaps, by certain requirements of the ceremonial, but the irregularity of the general village plan in many cases resulting from its adaptation to restricted sites, has given rise to the variations that are seen.
