The clearness with which all the steps of the gradual reduction of these openings can be traced in the exposed stone work is in marked contrast with the obscurity of such features in Zuñi. In the latter group, however, examples are occasionally seen where a doorway has been partly closed with masonry, leaving enough space at the top for a window. Often in such cases the filled-in masonry is thinner than that of the adjoining wall, and consequently the form of the original doorway is easily traced. Fig. 93, from an adobe wall in Zuñi, gives an illustration of this. The entrance doorway of the detached Zuñi house illustrated in [Pl. LXXXIII], has been similarly reduced in size, leaving traces of the original form in a slight offset. In modern times, both in Tusayan and Cibola, changes in the form and disposition of openings seem to have been made with the greatest freedom, but in the ancient pueblos altered doors or windows have rarely been found. The original placing of these features was more carefully considered, and the buildings were rarely subjected to unforeseen and irregular crowding.

In both ancient and modern pueblo work, windows, used only as such, seem to have been universally quadrilateral, offsets and steps being confined exclusively to doorways.
[ ROOF OPENINGS.]
The line of separation between roof openings and doors and windows is, with few exceptions, sharply drawn. The origin of these roof-holes, whose use at the present time is widespread, was undoubtedly in the simple trap door which gave access to the rooms of the first terrace. [Pl. XXXVIII], illustrating a court of Oraibi, shows in the foreground a kiva hatchway of the usual form seen in Tusayan. Here there is but little difference between the entrance traps of the ceremonial chambers and those that give access to the rooms of the first terrace; the former are in most cases somewhat larger to admit of ingress of costumed dancers, and the kiva traps are usually on a somewhat sharper slope, conforming to the pitch of the small dome-roof of the kivas, while those of the house terraces have the scarcely perceptible fall of the house roofs in which they are placed. In Zuñi, however, where the development and use of openings has been carried further, the kiva hatchways are distinguished by a specialized form that will be described later. An examination of the plans of the modern villages in Chapters II and III will show the general distribution of roof openings. Those used as hatchways are distinguishable by their greater dimensions, and in many cases by the presence of the ladders that give access to the rooms below. The smaller roof openings in their simplest form are constructed in essentially the same manner as the trap doors, and the width is usually regulated by the distance between two adjacent roof beams. The second series of small roof poles is interrupted at the sides of the opening, which sides are finished by means of carefully laid small stones in the same manner as are projecting copings. This finish is often carried several inches above the roof and crowned with narrow stone slabs, one on each of the four sides, forming a sort of frame which protects the mud plastered sides of the opening from the action of the rains. Examples of this simple type may be seen in many of the figures illustrating Chapters II and III, and in [Pl. XCVII]. Fig. 94 also illustrates common types of roof openings seen in Zuñi. Two of the examples in this figure are of openings that give access to lower rooms. Occasional instances are seen in this pueblo in which an exaggerated height is given to the coping, the result slightly approaching a square chimney in effect. [Fig. 95] illustrates an example of this form.
