This room is furnished with long, raised benches of masonry along the sides, a feature much more common at Zui than at Tusayan. Usually such benches extend along the whole length of a wall, but here the projection is interrupted on one side by the fireplace and chimney, and on the left it terminates abruptly near the beginning of a tier of mealing stones, in order to afford floor s.p.a.ce for the women who grind. The metates are arranged in the usual manner, three in a row, but there is an additional detached section placed at right angles to the main series. The sill of the doorway by which this room communicates with an adjoining one is raised about 18 inches above the floor, and is provided with a rudely mortised door in a single panel. Alongside is a small hole through which the occupant can prop the door on the inside of the communicating room.

The subsequent sealing of the small hand-hole with mud effectually closes the house against intrusion. The unusual height of this door sill from the floor has necessitated the construction of a small step, which is built of masonry and covered with a single slab of stone. All the doors of Zui are more or less raised above the ground or floor, though seldom to the extent shown in the present example. This room has no external door and can be directly entered only by means of the hatchway and ladder shown in the drawing. At one time this room was probably bounded by outer walls and was provided with both door and windows, though now no evidence of the door remains, and the windows have become niches in the wall utilized for the reception of the small odds and ends of a Zui household. The chimney of this house will be noticed as differing materially, both in form and in its position in the room, from the Tusayan examples. This form is, however, the most common type of chimney used in Zui at the present time, although many examples of the curved type also occur. It is built about midway of the long wall of the room. The Tusayan chimneys seldom occupy such a position, but are nearly always built in corners. The use of a pier or b.u.t.tress-projection for the support of a roof girder that is characteristic of Tusayan is not practiced at Zui to any extent. Deer horns have been built into the wall of the room to answer the purpose of pegs, upon which various household articles are suspended.

The various features, whose positions in the pueblo dwelling house have been briefly described above, will each be made the subject of more exhaustive study in tracing the various modifications of form through which they have pa.s.sed. The above outline will furnish a general idea of the place that these details occupy in the house itself.

KIVAS IN TUSAYAN.

_General use of kivas._--Wherever the remains of pueblo architecture occur among the plateaus of the southwest there appears in every important village throughout all changes of form, due to variations of environment and other causes, the evidence of chambers of exceptional character. The chambers are distinguishable from the typical dwelling rooms by their size and position, and, generally, in ancient examples, by their circular form. This feature of pueblo architecture has survived to the present time, and is prominent in all modern pueblos that have come under the writers notice, including the villages of Acoma and Jemez, belonging to the Rio Grande group, as well as in the pueblos under discussion. In all the pueblos that have been examined, both ancient and modern, with the exception of those of Tusayan, these special rooms, used for ceremonial purposes, occupy marginal or semidetached positions in the house cl.u.s.ters. The latter are wholly detached from the houses, as may be seen from the ground plans.

_Origin of the name._--Such ceremonial rooms are known usually by the Spanish term estufa, meaning literally a stove, and here used in the sense of sweat house, but the term is misleading, as it more properly describes the small sweat houses that are used ceremonially by lodge-building Indians, such as the Navajo. At the suggestion of Major Powell the Tusayan word for this everpresent feature of pueblo architecture has been adopted, as being much more appropriate. The word kiva, then, will be understood to designate the ceremonial chamber of the pueblo building peoples, ancient and modern.

_Antiquity of the kiva._--The widespread occurrence of this feature and its evident antiquity distinguish it as being especially worthy of exhaustive study, especially as embodied in its construction maybe found survivals of early methods of arrangement that have long ago become extinct in the constantly improving art of housebuilding, but which are preserved through the well known tendency of the survival of ancient practice in matters pertaining to the religious observances of a primitive people. Unfortunately, in the past the Zui have been exposed to the repressive policy of the Spanish authorities, and this has probably seriously affected the purity of the kiva type. At one time, when the ceremonial observances of the Zui took place in secret for fear of incurring the wrath of the Spanish priests, the original kivas must have been wholly abandoned, and though at the present time some of the kivas of Zui occupy marginal positions in the cell cl.u.s.ters, just as in many ancient examples, it is doubtful whether these rooms faithfully represent the original type of kiva. There seems to be but little structural evidence to distinguish the present kivas from ordinary large Zui rooms beyond the special character of the fireplace and of the entrance trap door, features which will be fully described later. At Tusayan, on the other hand, we find a distinct and characteristic structural plan of the kiva, as well as many special constructive devices. Although the position of the ceremonial room is here exceptional in its entire separation from the dwelling, this is due to clearly traceable influences in the immediate orograpic environment, and the wholly subterranean arrangement of most of the kivas in this group is also due to the same local causes.

[Ill.u.s.tration: Plate LII. Kiakima, plan.]

_Excavation of the kiva._--The tendency to depress or partly excavate the ceremonial chamber existed in Zui, as in all the ancient pueblo buildings which have been examined; but the solid rock of the mesa tops in Tusayan did not admit of the necessary excavation, and the persistence of this requirement, which, as I shall elsewhere show, has an important connection with the early types of pueblo building, compelled the occupants of these rocky sites to locate their kivas at points where depressions already existed. Such facilities were most abundant near the margins of the mesas, where in many places large blocks of sandstone have fallen out from the edge of the surface stratum, leaving nearly rectangular s.p.a.ces at the summit of the cliff wall. The construction of their villages on these rocky promontories forced the Tusayan builders to sacrifice, to a large extent, the traditional and customary arrangement of the kivas within the house-inclosed courts of the pueblo, in order to obtain properly depressed sites. This accidental effect of the immediate environment resulted in giving unusual prominence to the sinking of the ceremonial room below the ground surface, but a certain amount of excavation is found as a constant accompaniment of this feature throughout the pueblo region in both ancient and modern villages. Even at Zui, where the kivas appear to retain but few of the specialized features that distinguish them at Tusayan, the floors are found to be below the general level of the ground. But at Tusayan the development of this single requirement has been carried to such an extent that many of the kivas are wholly subterranean. This is particularly the case with those that occupy marginal sites on the mesas, such as have been referred to above. In such instances the broken-out recesses in the upper rocks have been walled up on the outside, roughly lined with masonry within, and roofed over in the usual manner. In many cases the depth of these rock niches is such that the kiva roof when finished does not project above the general level of the mesa summit, and its earth covering is indistinguishable from the adjoining surface, except for the presence of the box-like projection of masonry that surrounds the entrance trap door and its ladder (see Pl. Lx.x.xVII). Frequently in such cases the surface of the ground shows no evidence of the outlines or dimensions of the underlying room. Examples of such subterranean kivas may be seen in the foreground of the general view of a court in Oraibi (Pl. x.x.xVIII), and in the view of the dance rock at Walpi (Pl. XXIV). But such wholly subterranean arrangement of the ceremonial chamber is by no means universal even at Tusayan. Even when the kiva was placed within the village courts or close to the houses, in conformity to the traditional plan and ancient practice as evidenced in the ruins, naturally depressed sites were still sought; but such sites as the mesa margin affords were rarely available at any distance from the rocky rim. The result is that most of the court kivas are only partly depressed. This is particularly noticeable in a court kiva in Shumopavi, an ill.u.s.tration of which is given in Fig. 14.

The mungkiva or princ.i.p.al kiva of Shupaulovi, ill.u.s.trated in Pl. x.x.xIII, is scarcely a foot above the ground level on the side towards the houses, but its rough walls are exposed to a height of several feet down on the declivity of the knoll. The view of the stone corrals of Mashongnavi, shown in Pl. CIX, also ill.u.s.trates a kiva of the type described. This chamber is constructed on a sharp slope of the declivity where a natural depression favored the builders. On the upper side the roof is even with the ground, but on its outer or southern side the masonry is exposed to nearly the whole depth of the chamber. At the north end of Shumopavi, just outside the houses, are two kivas, one of which is of the semi-subterranean type. The other shows scarcely any masonry above the ground outside of the box-like entrance way. Pl.

Lx.x.xVIII ill.u.s.trates these two kivas as seen from the northeast, and shows their relation to the adjacent houses. The following (Fig. 21) ill.u.s.trates the same group from the opposite point of view.

_Access._--The last described semi-subterranean kiva and the similar one in the court of the village, show a short flight of stone steps on their eastern side. Entrance to the ceremonial chamber is prevented when necessary by the removal of the ladder from the outside, or in some instances by the withdrawal of the rungs, which are loosely inserted into holes in the side pieces. There is no means of preventing access to the exposed trap doors, which are nearly on a level with the ground. As a matter of convenience and to facilitate the entrance into the kiva of costumed and masked dancers, often enc.u.mbered with clumsy paraphernalia, steps are permanently built into the outside wall of the kiva in direct contradiction to the ancient principles of construction; that is, in having no permanent or fixed means of access from the ground to the first roof. These are the only cases in which stone steps spring directly from the ground, although they are a very important feature in Tusayan house architecture above the first story, as may be seen in any of the general views of the villages. The justification of such an arrangement in connection with the indefensible kiva roof lies obviously in the different conditions here found as compared with the dwellings.

[Ill.u.s.tration: Fig. 21. North kivas of Shumopavi, seen from the southwest.]

The subterranean kiva of the Shumopavi group, above ill.u.s.trated, is exceptional as occurring at some distance from the mesa rim. Probably all such exceptions to the rule are located in natural fissures or crevices of the sandstone, or where there was some unusual facility for the excavation of the site to the required depth. The most noteworthy example of such inner kiva being located with reference to favorable rock fissures has been already described in discussing the ground plan of Walpi and its southern court-inclosed kiva (p. 65).

_Masonry._--The exterior masonry of these chambers seems in all cases to be of ruder construction than that of the dwelling houses. This is particularly noticeable in the kivas of Walpi on the mesa edge, but is apparent even in some of the Zui examples. One of the kivas of house No. 1 in Zui, near the churchyard, has small openings in its wall that are rudely framed with stone slabs set in a stone wall of exceptional roughness. Apparently there has never been any attempt to smooth or reduce this wall to a finished surface with the usual coating of adobe mud.

[Ill.u.s.tration: Plate LIII. Site of Kiakima, at base of Taaiyalana.]

In Tusayan also some of the kiva walls look as though they had been built of the first material that came to hand, piled up nearly dry, and with no attempt at the c.h.i.n.king of joints, that imparts some degree of finish to the dwelling-house masonry. The inside of these kivas, however, is usually plastered smoothly, but the interior plastering is applied on a base of masonry even in the case of the kivas that are wholly subterranean. It seems to be the Tusayan practice to line all sides of the kivas with stone masonry, regardless of the completeness and fitness of the natural cavity. It is impossible, therefore, to ascertain from the interior of a kiva how much of the work of excavation is artificial and how much has been done by nature. The lining of masonry probably holds the plastering of adobe mud much better than the naked surface of the rock, but the Tusayan builders would hardly resort to so laborious a device to gain this small advantage. The explanation of this apparent waste of labor lies in the fact that kivas had been built of masonry from time immemorial, and that the changed conditions of the present Tusayan environment have not exerted their influence for a sufficient length of time to overcome the traditional practice. As will be seen later, the building of a kiva is accompanied by certain rites and ceremonies based on the use of masonry walls, additional testimony of the comparatively recent date of the present subterranean types.

_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. x.x.x) to have the same direction, viz, facing southeast. In Shumopavi (Pl. x.x.xIV) 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. x.x.xVI). 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.

In Zui there was an evident purpose to preserve a certain uniformity of direction in the kiva entrances. In house No. 1 (Pls. LXXVI and LXXVII) there are two kivas, distinguishable on the plan by the large divided trap door. The entrance of these both face southeast, and it can readily be seen that this conformity has been provided intentionally, since the rooms themselves do not correspond in arrangement. The roof opening is in one case across the room and in the other it is placed longitudinally. As has been pointed out above, the general plan of arranging the kivas is not so readily distinguished in Zui as in Tusayan. Uniformity, so far as it is traceable, is all the more striking as occurring where there is so much more variation in the directions of the walls of the houses. Still another confirmation is furnished by the pueblo of Acoma, situated about 60 miles eastward from Zui. Here the kivas are six in number and the directions of all the examples are found to vary but a few degrees. These also face east of south.

There are reasons for believing that the use of rectangular kivas is of later origin in the pueblo system of building than the use of the circular form of ceremonial chamber that is of such frequent occurrence among the older ruins. Had strict orientation of the rectangular kiva prevailed for long periods of time it would undoubtedly have exerted a strong influence towards the orientation of the entire pueblo cl.u.s.ters in which the kivas were incorporated; but in the earlier circular form, the constructional ceremonial devices could occupy definite positions in relation to the cardinal points at any part of the inner curve of the wall without necessarily exerting any influence on the directions of adjoining dwellings.

[Ill.u.s.tration: Plate LIV. Recent wall at Kiakima.]

_The ancient form of kiva._--In none of the ruins examined in the province of Tusayan have distinct traces of ancient kivas been found, nor do any of them afford evidence as to the character of the ceremonial rooms. It is not likely, however, that the present custom of building these chambers wholly under ground prevailed generally among the earlier Tusayan villages, as some of the remains do not occupy sites that would suggest such arrangement. The typical circular kiva characteristic of most of the ancient pueblos has not been seen within the limits of Tusayan, although it occurs constantly in the ruins of Canyon de Ch.e.l.ly which are occasionally referred to in Tusayan tradition as having been occupied by related peoples. Mr. Stephen, however, found vestiges of such ancient forms among the debris of fallen walls occupying two small knolls on the edge of the first mesa, at a point that overlooks the broken-down ruin of Sikyatki. On the southeast shoulder of one of the knolls is a fragment of a circular wall which was originally 12 feet in diameter. It is built of flat stones, from 2 to 4 inches thick, 6 to 8 inches wide, and a foot or more in length, nearly all of which have been pecked and dressed. Mud mortar has been sparingly used, and the masonry shows considerable care and skill in execution; the curve of the wall is fairly true, and the interstices of the masonry are neatly filled in with smaller fragments, in the manner of some of the best work of the Canyon de Ch.e.l.ly ruins.

The knoll farther south shows similar traces, and on the southeast slope is the complete ground plan of a round structure 16 feet in diameter.

At one point of the curved wall, which is about 22 inches thick, occurs the characteristic recessed katc.h.i.n.kihu (described later in discussing the interior of kivas) indicating the use of this chamber for ceremonial purposes.

Although these remains probably antedate any of the Tusayan ruins discussed above (Chapter II), they suggest a connection and relationship between the typical kiva of the older ruins and the radically different form in use at the present time.

_Native explanations of position._--Notwithstanding the present practice in the location of kivas, ill.u.s.trated in the plans, the ideal village plan is still acknowledged to have had its house-cl.u.s.ters so distributed as to form inclosed and protected courts, the kivas being located within these courts or occupying marginal positions in the house-cl.u.s.ters on the edge of the inclosed areas. But the native explanations of the traditional plan are vague and contradictory.

In the floor of the typical kiva is a sacred cavity called the sipapuh, through which comes the beneficent influence of the deities or powers invoked. According to the accounts of some of the old men the kiva was constructed to inclose this sacred object, and houses were built on every side to surround the kiva and form its outer wall. In earlier times, too, so the priests relate, people were more devout, and the houses were planned with their terraces fronting upon the court, so that the women and children and all the people, could be close to the masked dancers (katchinas) as they issued from the kiva. The spectators filled the terraces, and sitting there they watched the katchinas dance in the court, and the women sprinkled meal upon them, while they listened to their songs. Other old men say the kiva was excavated in imitation of the original house in the interior of the earth, where the human family were created, and from which they climbed to the surface of the ground by means of a ladder, and through just such an opening as the hatchway of the kiva. Another explanation commonly offered is that they are made underground because they are thus cooler in summer, and more easily warmed in winter.

All these factors may have had some influence in the design, but we have already seen that excavation to the extent here practiced is wholly exceptional in pueblo building and the unusual development of this requirement of kiva construction has been due to purely local causes.

In the habitual practice of such an ancient and traditional device, the Indians have lost all record of the real causes of the perpetuation of this requirement. At Zui, too, a curious explanation is offered for the partial depression of the kiva floor below the general surrounding level. Here it is naively explained that the floor is excavated in order to attain a liberal height for the ceiling within the kiva, this being a room of great importance. Apparently it does not occur to the Zui architect that the result could be achieved in a more direct and much less laborious manner by making the walls a foot or so higher at the time of building the kiva, after the manner in which the same problem is solved when it is encountered in their ordinary dwelling house construction. Such explanations, of course, originated long after the practice became established.

METHODS OF KIVA BUILDING AND RITES.

The external appearance of the kivas of Tusayan has been described and ill.u.s.trated; it now remains to examine the general form and method of construction of these subterranean rooms, and to notice the attendant rites and ceremonies.

_Typical plans._--All the Tusayan kivas are in the form of a parallelogram, usually about 25 feet long and half as wide, the ceiling, which is from 5 to 8 feet high, being slightly higher in the middle than at either end. There is no prescribed rule for kiva dimensions, and seemingly the size of the chamber is determined according to the number who are to use it, and who a.s.sume the labor of its construction. A list of typical measurements obtained by Mr. Stephen is appended (p. 136).

[Ill.u.s.tration: Plate LV. Matsaki, plan.]

An excavation of the desired dimensions having been made, or an existing one having been discovered, the person who is to be chief of the kiva performs the same ceremony as that prescribed for the male head of a family when the building of a dwelling house is undertaken. He takes a handful of meal, mixed with piki crumbs, and a little of the crumbled herb they use as tobacco, and these he sprinkles upon the ground, beginning on the west side, pa.s.sing southward, and so around, the sprinkled line he describes marking the position to be occupied by the walls. As he thus marks the compa.s.s of the kiva, he sings in a droning tone Si-ai, a-hai, a-hai, si-ai, a-hai--no other words but these. The meaning of these words seems to be unknown, but all the priests agree in saying that the archaic chant is addressed to the sun, and it is called Kitdauwi--the House Song. The chief then selects four good-sized stones of hard texture for corner stones, and at each corner he lays a baho, previously prepared, sprinkles it with the mixture with which he has described the line of the walls, and then lays the corner stone upon it.

As he does this, he expresses his hope that the walls will take good root hold, and stand firm and secure.

The men have already quarried or collected a sufficient quant.i.ty of stone, and a wall is built in tolerably regular courses along each side of the excavation. The stones used are roughly dressed by fracture; they are irregular in shape, and of a size convenient for one man to handle.

They are laid with only a very little mud mortar, and carried up, if the ground be level, to within 18 inches of the surface. If the kiva is built on the edge of the cliff, as at Walpi, the outside wall connects the sides of the gap, conforming to the line of the cliff. If the surface is sloping, the level of the roof is obtained by building up one side of the kiva above the ground to the requisite height as ill.u.s.trated in Fig. 21. One end of the Goat kiva at Walpi is 5 feet above ground, the other end being level with the sloping surface. When the ledge on the precipitous face of the mesa is uneven it is filled in with rough masonry to obtain a level for the floor, and thus the outside wall of some of the Walpi kivas is more than 12 feet high, although in the interior the measurement from floor to ceiling is much less.

Both cottonwood and pine are used for the roof timbers; they are roughly dressed, and some of them show that an attempt has been made to hew them with four sides, but none are square. In the roof of the Goat kiva, at Walpi, are four well hewn pine timbers, measuring exactly 6 by 10 inches, which are said to have been taken from the mission house built near Walpi by the Spanish priests some three centuries ago. The ceiling plan of the mungkiva of Shupaulovi (Fig. 23) shows that four of these old Spanish squared beams have been utilized in its construction. One of these is covered with a rude decoration of gouged grooves and bored holes, forming a curious line-and-dot ornament. The other kiva of this village contains a single undecorated square Spanish roof beam. This beam contrasts very noticeably with the rude round poles of the native work, one of which, in the case of the kiva last mentioned, is a forked trunk of a small tree. Some of the Indians say that the timbers were brought by them from the Shumopavi spring, where the early Spanish priests had established a mission. According to these accounts, the home mission was established at Walpi, with another chapel at Shumopavi, and a third and important one at Awatubi.

One man, Sikapiki by name, stated that the squared and carved beams were brought from the San Francisco Mountains, more than a hundred miles away, under the direction of the priests, and that they were carved and finished prior to transportation. They were intended for the chapel and cloister, but the latter building was never finished. The roof timbers were finally distributed among the people of Shumopavi and Shupaulovi.

At Shumopavi one of the kivas, known, as the Nuvwatikyuobi (The-high-place-of-snow--San Francisco Mountains) kiva, was built only 8 years ago. The main roof timbers are seven in number. Four of them are hewn with flat sides, 8 by 12 inches to 9 by 13 inches; the other three are round, the under sides slightly hewn, and they are 12 inches in diameter. These timbers were brought from the San Francisco Mountains while the Spaniards were here. The Shumopavi account states that the people were compelled to drag most of the timbers with ropes, although oxen were also used in some cases, and that the Spaniards used them to roof their mission buildings. After the destruction of the mission these timbers were used in the construction of a dwelling house, which, falling into ruin, was abandoned and pulled down. Subsequently they were utilized as described above. In the Teosobi, Jay, the main timbers were taken out of it many years ago and used in another kiva. The timbers now in the roof are quite small and are laid in pairs, but they are old and much decayed. In the Gyarzobi, Paroquet, are six squared timbers from the Spanish mission buildings, measuring 9 by 13 inches, 8 by 12 inches, etc. These have the same curious grooved and dotted ornamentation that occurs on the square beam of Shupaulovi, above described. At the other end of the kiva are also two unusually perfect round timbers that may have come from the mission ruin. All of these show marks of fire, and are in places deeply charred.

In continuation of the kiva building process, the tops of the walls are brought to an approximate level. The main roof timbers are then laid parallel with the end walls, at irregular distances, but less than 3 feet apart, except near the middle, where a s.p.a.ce of about 7 feet is left between two beams, as there the hatchway is to be built. The ends of the timbers rest upon the side walls, and as they are placed in position a small feather, to which a bit of cotton string is tied (nakwakwoci) is also placed under each. Stout poles, from which the bark has been stripped, are laid at right angles upon the timbers, with slight s.p.a.ces between them. Near the center of the kiva two short timbers are laid across the two main beams about 5 feet apart; this is done to preserve a s.p.a.ce of 5 by 7 feet for the hatchway, which is made with walls of stone laid in mud plaster, resting upon the two central beams and upon the two side pieces. This wall or combing is carried up so as to be at least 18 inches above the level of the finished roof.

Across the poles, covering the rest of the roof, willows and straight twigs of any kind are laid close together, and over these is placed a layer of dry gra.s.s arranged in regular rows. Mud is then carefully spread over the gra.s.s to a depth of about 3 inches, and after it has nearly dried it is again gone over so as to fill up all the cracks.

A layer of dry earth is then spread over all and firmly trodden down, to render the roof water-tight and bring its surface level with the surrounding ground, following the same method and order of construction that prevails in dwelling-house buildings.

[Ill.u.s.tration: Plate LVI. Standing wall at Pinawa.]

Short timbers are placed across the top of the hatchway wall, one end of which is raised higher than the other, so as to form a slope, and upon these timbers stone slabs are closely laid for a cover. (See Pl.

Lx.x.xVII.) An open s.p.a.ce, usually about 2 by 4 feet, is preserved, and this is the only outlet in the structure, serving at once as doorway, window, and chimney.

The roof being finished, a floor of stone flags is laid; but this is never in a continuous level, for at one end it is raised as a platform some 10 or 12 inches high, extending for about a third of the length of the kiva and terminating in an abrupt step just before coming under the hatchway, as ill.u.s.trated in the ground plan of the mungkiva of Shupaulovi (Fig. 22, and also in Figs. 25 and 27). On the edge of the platform rests the foot of a long ladder, which leans against the higher side of the hatchway, and its tapering ends project 10 or 12 feet in the air. Upon this platform the women and other visitors sit when admitted to witness any of the ceremonies observed in the kiva. The main floor in a few of the kivas is composed of roughly hewn planks, but this is a comparatively recent innovation, and is not generally deemed desirable, as the movement of the dancers on the wooden floor shakes the fetiches out of position.

On the lower or main floor a shallow pit of varying dimensions, but usually about a foot square, is made for a fireplace, and is located immediately under the opening in the hatchway. The intention in raising the hatchway above the level of the roof and in elevating the ceiling in the middle is to prevent the fire from igniting them. The ordinary fuel used in the kiva is greasewood, and there are always several bundles of the shrub in its green state suspended on pegs driven in the wall of the hatchway directly over the fire. This shrub, when green, smolders and emits a dense, pungent smoke, but when perfectly dry, burns with a bright, sparkling flame.

Across the end of the kiva on the main floor a ledge of masonry is built, usually about 2 feet high and 1 foot wide, which serves as a shelf for the display of fetiches and other paraphernalia during stated observances (see Fig. 22). A small, niche-like aperture is made in the middle of this ledge, and is called the katchin kihu (katchina house).

During a festival certain masks are placed in it when not in use by the dancers. Some of the kivas have low ledges built along one or both sides for use as seats, and some have none, but all except two or three have the ledge at the end containing the katchina house.

In the main floor of the kiva there is a cavity about a foot deep and 8 or 10 inches across, which is usually covered with a short, thick slab of cottonwood, whose upper surface is level with the floor. Through the middle of this short plank and immediately over the cavity a hole of 2 or 2 inches in diameter is bored. This hole is tapered, and is accurately fitted with a movable wooden plug, the top of which is flush with the surface of the plank. The plank and cavity usually occupy a position in the main floor near the end of the kiva. This feature is the sipapuh, the place of the G.o.ds, and the most sacred portion of the ceremonial chamber. Around this spot the fetiches are set during a festival; it typifies also the first world of the Tusayan genesis and the opening through which the people first emerged. It is frequently so spoken of at the present time.

Other little apertures or niches are constructed in the side walls; they usually open over the main floor of the kiva near the edge of the dais that forms the second level, that upon which the foot of the ladder rests. These are now dedicated to any special purpose, but are used as receptacles for small tools and other ordinary articles. In early days, however, these niches were used exclusively as receptacles for the sacred pipes and tobacco and other smaller paraphernalia.
