Fig. 302.—Bowlders in footway,
cavate lodges.

In the cavate lodges window openings are not found; there is but one opening, the doorway, and this is of a pronounced and peculiar type. As a rule these doorways are wider at the top than at the bottom and there are no corners, the opening roughly approximating the shape of a pear with the smaller end downward. The upper part of the opening consists always of the naked rock, but the lower part is generally

framed with slabs of sandstone. Plate XLIX shows an example that occurs in the upper tier of lodges at its eastern end. The floor of this lodge is about 2 feet above the bench from which it was entered, and this specimen fails to show a feature which is very common in this group—a line of water-worn bowlders extending from the exterior to the interior of the lodges through the doorway and arranged like stepping stones. This feature is shown in figure 302, which represents the doorway of group E, shown on the general map ([plate XXV]) and on the detailed

plan, [figure 297]. Figure 303 shows a type in which the framing is extended up on one side nearly to the top, while on the other side it extends only to half the height of the opening, which above the framing is hollowed out to increase its width. This example occurs near that shown in plate XLIX, and the floor of the chamber is raised about 2 feet above the bench from which it is entered. The illustration gives a view from the interior, looking out, and the large opening on the right was caused by the comparatively recent breaking out of the wall. Figure 303 shows the doorway to the group of chambers marked E on the general map, an interior view of which is shown in figure 302. In this example the obvious object of the framing was to reduce the size of the opening, and to accomplish this the slabs were set out 10 or 12 inches from the rock forming the sides of the opening, and the intervening space was filled in with rubble. Plate [plate XXXII], which shows the interior of the main room in group D, shows also the large doorway on the north.

in Canyon de Chelly.

It will be noticed that these doorways all conform to one general plan and that this plan required an opening considerably larger in its upper third than in the lower two-thirds of its height. This requirement seems to be the counterpart or analogue of the notched doorway, which is the standard type in the cliff ruins of Canyon de Chelly and other regions, and still very common in Tusayan (Moki). Figure 304 shows a notched doorway in Canyon de Chelly and figure 305 gives an example of the same type of opening in Tusayan. The object of this peculiar shape in the regions mentioned has been well established,[9] and there is no reason to suppose that similar conditions and a similar object would not produce a similar result here. This type of opening had its origin in the time when the pueblo builders had no means, other than blankets, of temporarily closing door openings and when all the supplies of the village were brought in on the backs of the inhabitants. In order to secure protection against cold and storm the opening was made of the smallest possible size consistent with its use, and the upper part of the opening was made larger in order to permit the introduction of back loads of faggots and other necessaries. This purpose would be almost as well served by the openings of the cavate lodges as by the notched doorway, and at the same time the smallest possible opening was exposed to the weather. The two types of openings seem

simply to be two different methods of accomplishing the same purpose—one in solid rock, the other in masonry. That it was considered desirable to reduce the openings as much as possible is evident from the employment of framing slabs in the lower portions, reducing the width of that part generally to less than a foot, while the upper portions are usually 3 feet and more in width, and the absence of framing slabs in the upper part of the openings was probably due to their use as suggested; no slabs could be attached with sufficient firmness to resist the drag of a back load of wood, for example, forced between them. The strict confinement of door openings to one type suggests a short, rather than a long, occupancy of the site under discussion, a suggestion which is borne out by other details; and this unity of design renders it difficult to form a conclusion as to the relative age of the two types of openings under discussion. So far as the evidence goes, however, it supports the conclusion that the doorways of the cavate lodges were derived from a type previously developed, and that the idea has been modified and to some extent adapted to a different environment; for if the idea had been developed in the cavate lodges there would be a much greater number of variations than we find in fact. There can be
