External use of this material is much rarer, particularly in Zuñi, where only a few walls of upper stories are whitened. Where it is not protected from the rains by an overhanging coping or other feature, the finish is not durable. Occasionally where a doorway or other opening has been repaired the evidences of patchwork are obliterated by a surrounding band of fresh plastering, varying in width from 4 inches to a foot or more. Usually this band is laid on as a thick wash of adobe, but in some instances a decorative effect is attained by using white. It is curious to find that at Tusayan the decorative treatment of the finishing wash has been carried farther than, at Zuñi. The use of a darker band of color about the base of a whitewashed room has already been noticed in the description of a Tusayan interior. On many of the outer walls of upper stories the whitewash has been stopped within a foot of the coping, the unwhitened portion of the walls at the top having the effect of a frieze. In a second story house of Mashongnavi, that had been carefully whitewashed, additional decorative effect was produced by tinting a broad band about the base of the wall with an application of bright pinkish clay, which was also carried around the doorway as an enframing band, as in the case of the Zuñi door above described. The angles on each side, at the junction of the broad base band with the narrower doorway border, were filled in with a design of alternating pink and white squares. This doorway is illustrated in Fig. 36. Farther north, on the same terrace, the jamb of a whitewashed doorway was decorated with the design shown on the right hand side of Fig. 36, executed also in pink clay. This design closely resembles a pattern that is commonly embroidered upon the large white “kachina,” or ceremonial blankets. It is not known whether the device is here regarded as having any special significance. The pink clay in which these designs have been executed has in Sichumovi been used for the coating of an entire house front. [Illustration: Fig. 36.
