This kiva is better plastered than the mungkiva and shows in places evidences of many successive coats. The general rule of applying the interior plastering of the kiva on a base of masonry has been violated in this example. The north end and part of the adjoining sides have been brought to an even face by filling in the inequalities of the excavation with reeds which are applied in a vertical position and are held in place by long, slender, horizontal rods, forming a rude matting or wattling. The rods are fastened to the rocky wall at favorable points by means of small prongs of some hard wood, and the whole of the primitive lathing is then thickly plastered with adobe mud. Mr. Stephen found the Ponobi kiva of Oraibi treated in the same manner. The walls are lined with a reed lathing over which mud is plastered. The reed used is the Bakabi (_Phragmites communis_) whose stalks vary from a quarter of an inch to three-quarters of an inch in diameter. In this instance the reeds are also laid vertically, but they are applied to the ordinary mud-laid kiva wall and not directly to the sides of the natural excavation. The vertical laths are bound in place by horizontal reeds laid upon them 1 or 2 feet apart. The horizontal reeds are held in place by pegs of greasewood driven into the wall at intervals of 1 or 2 feet and are tied to the pegs with split yucca. These specimens are very interesting examples of aboriginal lathing and plastering applied to stone work. [Illustration: Fig. 28. Interior view of a kiva hatchway in Tusayan.]
