If it is well hidden, the grain may remain in the cists for a long time if not withdrawn for consumption; but as a rule it is taken away a few months later. The annual emigration of the Navaho commences soon after the harvest, and at intervals during the winter and spring, and in summer, if the supply is not then exhausted, visits are paid to the cists and portions of the grain are carried away.
A large proportion of the cists are of modern Navaho work, but that some of them were used by the pueblo people who preceded them seems probable from the similarity in horticultural methods, and from the small size of many of the villages. A village inhabited by half a dozen people was not uncommon; one which could accommodate more than fifty was rare.
Moreover, some of the storage cists that occur in conjunction with dwellings differ from the latter only in size and in their separation from the other rooms. The masonry is quite as good as that of the houses, and much superior to the Navaho work.
Plate LXI shows an example which occurs in the lower part of the canyon, at the point marked 1 on the map. It is placed on a little ledge or block of rock, 12 feet above the stream and about 8 feet above the bottom land below it. This is the first considerable area of bottom land in the canyon. The cist is 2 feet square inside and occupies the whole width of the rock. An exceptionally large amount of mud plaster was used on the walls, which are better finished outside than inside. Access was had by hand-holes in the rock, now almost obliterated. Originally the structure consisted of two or more rooms.
A little below this site there are some well-executed pictographs, and on some rocks immediately to the right some crude work of the Navaho of the same sort. To the left of the cist a round hole 6 or 8 inches in diameter has been pecked into the almost vertical face of the rock. The purpose of this is not clear.
The storage of water was so seldom attempted, or perhaps so seldom necessary, that only one example of a reservoir was found. This has already been described (page 126). If the cliff ruins were defensive structures, a supply of water must have been kept in them, and where this requirement was common, as it would be under the hypothesis, certainly some receptacle other than jars of pottery would be provided.
Few, if any, of the cliff outlooks are so situated that a supply of water could be procured without descending to the stream bed, and without a supply of water the most impregnable site in the canyon would have little value.
The number of burial cists in the canyon is remarkable; there are hundreds of them. Practically every ruin whose walls are still standing contains one or more, some have eight or ten. They are all of Navaho origin and in many of them the remains of Navaho dead may still be seen.
Possibly the Navaho taboo of their own dead has brought about the partial taboo of the cliff dwellers" remains which prevails, and which is an element that must be taken into account in any discussion of the antiquity of the ruins.
The burial cists are built usually in a corner or against a wall of a cliff dweller"s house, but sometimes they are built against a cliff wall, and occasionally stand out alone. The masonry is always rough, much inferior to the old walls against which it generally rests, and usually very flimsy. The structures are dome-shape when standing alone, or in the shape of a section of a dome when placed against other walls.
The natural bedding of the stone is sometimes wholly ignored, and in some cases the walls consist merely of thin slabs of stone on edge, held together with ma.s.ses of mud, the whole presenting an average thickness of less than 3 inches. Such structures on ordinary sites would not last six months; protected as they are they might last for many years.
[Ill.u.s.tration: Plate LXI Storage Cist in Canyon De Ch.e.l.ly]
Not all the Navaho dead in the canyon find their last resting place in the ruins. Graves can be seen under bowlders and rocks high up on the talus; and in one place in De Ch.e.l.ly a number of little piles of stones are pointed out as the burial places of "many Americans," who, it is said, were killed by the Navaho in their last war. It is also said that in the olden days, when the Navaho considered De Ch.e.l.ly their stronghold and the heart of their country, the remains of prominent men of the tribe were often brought to the canyon for interment in the ruins. Such burials are still made, both in the ruins themselves and in cists on similar sites.
As a whole the Navaho burial cists are much more difficult of access than the ruins, and some of them appear to be now really inaccessible, a statement which can be made of but few ruins. Some of them appear to have been reached from above. The agility and dexterity of the Navaho in climbing the cliffs is remarkable, and possibly some of the sites now apparently inaccessible are not so considered by them. As before stated, there are a number of Navaho foot trails out of the canyon, where shallow pits or holes have been pecked in the rock as an aid in the more difficult places, and similar aids were often employed to afford access to storage and burial cists. Plate LVI shows a site in the lower part of the canyon where such means have been employed. The pits in the rock are so much worn by atmospheric erosion that the ascent now is very dangerous. The cove or ledge to which they lead is about halfway up the cliff, and on it are a number of cists, one of them still intact, with a doorway. The masonry consists of large slabs of sandstone set on edge, sometimes irregularly one above another, the whole being roughly plastered inside and out. About 200 yards farther up the cove, on the same side, there is a series of foot holes leading to a small cave about halfway up, and thence upward and probably out of the canyon. They are probably of Navaho origin.
[Ill.u.s.tration: Fig. 68--Cist composed of upright slabs.]
The use of stone on edge is apparently confined to these cists. Figure 68 shows a structure which occurs a little above the ruin marked 37 on the map. The walls consist of thin slabs of stone set upright and roughly plastered where they meet. Instances of the use of stone in this way are not uncommon in the pueblo country, and there are a number of examples in De Ch.e.l.ly.
As before stated, the typical Navaho burial cist is of dome shape. The roof or upper portion is supported on sticks so arranged as to leave a small square opening in the top. Apparently at some stage in its existence this hole is closed and sealed, but examples were examined which were very old and one which was but twenty-four hours old, but in neither case was the opening closed. Doubtless the opening has some ceremonial significance; it is not of any actual use, as it is too small to permit the pa.s.sage of a human body. Plate LXII shows a typical cist in good order and another such broken down. These examples occur at the point marked 6 on the map, in the ruin shown in plate LIII. This site is of comparatively easy access, and there are many others equally easy or even more so, but, on the other hand, there are many Sites which now seem to be wholly inaccessible.
DEFENSIVE AND CONSTRUCTIVE EXPEDIENTS
The cliff ruins have always been regarded as defensive structures, sometimes even as fortresses, but in De Ch.e.l.ly whatever value they have in this respect is due solely to the sites they occupy. There are many places here where slight defensive works on the approaches to sites would increase their value a hundredfold, but such works were apparently never constructed. Furthermore, the ruins themselves never show even a suggestion of the influence of the defensive motive, except in the two possible instances already mentioned. The ordinary or dwelling-house plan has not been at all modified, not even to the extent that it has in the modern pueblos. If the cliff ruins were defensive structures it would certainly seem that an influence strong enough to bring about the occupancy of such inconvenient and unsuitable sites would also be strong enough to bring about some modifications in the architecture, modifications which would render more suitable sites available. The influence of the physical environment on pueblo architecture, and the sensitiveness of the latter to such influence, has already been commented on. Moreover, it also has been stated that, so far as known, but one instance occurs in the canyon where provision was made for the storage of water; yet without water the strongest "fortress" in the canyon could not withstand a siege of forty-eight hours. Further, a.s.suming that the structures were defensive, and well prepared to resist attack, if necessary, for several days, only a few such attacks would be required to cause their abandonment, for the crops on the canyon bottom, practically the sole possessions of the dwellers in the canyon, would necessarily be lost.
[Ill.u.s.tration: Plate LXII Navaho Burial Cists]
These are some of the difficulties that stand in the way of the a.s.sumption that the cliff ruins were defensive structures or permanent homes. If, however, we adopt the hypothesis that they were farming outlooks occupied only during the farming season, and then only for a few days or weeks at a time, after the manner that such outlooks are used by the Pueblo Indians at the present time, most of the difficulties vanish.
The apparent inaccessibility of many of the sites disappears on close examination, and we must not forget that places really difficult of access to us would not necessarily be so regarded by a people accustomed to that manner of life. Many locations which could not be surpa.s.sed as defensive sites were not occupied, while others much inferior in this respect were built upon. It was very seldom that the natural conditions were modified, even to the extent of selecting a route of access other than that which, would naturally be followed, and, of course, the easiest route for the cliff dwellers would be also the easiest route for their enemies. In many cases the easiest way of access, which was the one used by the cliff dwellers, was not direct. It was not commanded by the immediate site of the dwellings, except in its upper part, and in some cases not at all. Enemies could climb to the very doors of the houses before they could be seen or attacked. The absence of military knowledge and skill, and of any attempt to fortify or strengthen a site, or even to fully utilize its natural defensive advantages, is characteristic of the cliff ruins of De Ch.e.l.ly. If the cliff dwellers were driven to the use of such places by a necessity for defense, this absence is remarkable, especially as there is evidence that the settlements were occupied for a number of, perhaps a great many, years.
Under the head of constructive expedients we have a different result.
The difficulties which came from the occupancy of exceptional sites were promptly reflected in the construction, and unusual ways and methods were adopted to overcome them. These methods are the more interesting in that they were not always successful. It sometimes happened that walls had to be placed on a foundation of smooth, sloping rock. In such cases the rock was never cut away, but timbers were employed to hold the wall in place. In some instances the timbers were laid at right angles to the line of front wall, at points where cross walls joined it inside. The front wall thus rested partly on the ends of timbers and partly on rock, while the other ends of the timbers were held in place by the cross walls built upon them. An example of this construction is shown in plate LII. In other instances, where the surface was irregular but did not slope much, timbers were laid on the wall lines and the masonry rested partly upon them. An example of this occurs in the Casa Blanca ruin, shown in plate XLVII. Still another method of using timber in masonry occurs in a number of ruins. It was seldom effective and apparently was confined to this region. This consists of the incorporation into the masonry of upright logs. Figure 69 shows an example that occurs at the point marked 32 on the map. The site here is an especially difficult one, as the builders were compelled to place walls not only on sloping rock foundations, but also on loose debris, and the vertical timber support is quite common. The three kivas which are shown on the plan occupied the front of the village, and their front walls have fallen out. Apparently the same accident has happened at least once, if not several times, before, and a fragment of a previous front wall has slipped down 3 or 4 feet, and was left there when the kiva was repaired.
The round dots shown on the plan, two in the wall of the central kiva and one on the east, represent vertical timbers incorporated in the masonry. The tops of these logs reach the level of the top of the bench in the kiva, and their lower ends rest in cavities in the rocks. The eastern one was removed and was found to be about 2 feet long. The upper half was charred, although formerly inclosed completely in the masonry, as though it had been burned off to the required length. The lower end was hacked off with some blunt implement, and as nearly squared as it could be done with such means. It was set into a socket or hole pecked in the solid rock and plastered in with clay. In the outer portion of the eastern wall of the central kiva there are many marks of sticks, 3 to 4 inches in diameter and placed vertically.
[Ill.u.s.tration: Fig. 69--Retaining walls in Canyon de Ch.e.l.ly.]
Although timbers as an aid to masonry occur in many ruins, they predominate in those which have been suggested as the sites most recently occupied; but in the Chaco ruins timber has been used extensively and much more skillfully than here. Instances occur where a cross wall has been tied into a front wall with timber, and so effective was the device that in one instance a considerable section of cross wall can be seen suspended in the air, being completely broken out below and now supported wholly by the ties. Instances can also be seen where part.i.tion walls are supported on crossbeams at some distance from the ground, forming large and convenient openings between rooms; but nothing of that kind was seen in De Ch.e.l.ly. In the latter region wherever horizontal timbers are used for the support of masonry they rest on the bed rock.
[Ill.u.s.tration: Plate LXIII Kiva in Ruin No. 10, Showing Second-Story Walls]
The same ruin (No. 32) contains an elaborate system of retaining avails, which are shown partly in figure 69. At first a retaining wall was built immediately in front of the main kiva, which is now 5 feet high outside.
Apparently this did not serve the purpose intended, for another and much heavier wall was built immediately next to it. This wall is 4 feet thick, flush on top and inside, but 10 feet high outside. At half its height it has a step back of 6 inches. It would seem that even this heavy construction did not suffice, and still another wall was built outside of and next to it. This wall is nearly or quite as heavy as the one described, and its top is on the level of the foot of that wall, but it is 12 feet high outside. Something of the character of the site may be inferred from the arrangement of these walls, which have a combined vertical fall of 27 feet in a horizontal distance of less than 15 feet.
The outer or lower wall has a series of very heavy timbers projecting from its face; these are placed irregularly. It should be noted that access to this village was from the bench on either side, and that it could not be reached from the front, where these walls occur. There are other walls on the lower slope, similarly reinforced.
A little to the right of the point where these retaining walls occur there is a room in which horizontal beams have been incorporated in the masonry. A similar use of timber occurs in ruin No. 16 and is shown in plate LX. Why timber should be used in this way is not clear. It may be that when the supply was placed on the ground the builders found that they had more timber than was needed for a roof and used the excess in the wall rather than bring up more stone. The posts which were placed vertically and built into the wall were always short; perhaps they were fragments or ends cut from roofing timbers that were found to be too long. In many instances they failed to hold the walls, and possibly the pit holes in sloping rock, which are numerous on some sites, indicate places where this expedient was formerly employed.
It is singular that the necessity for such expedients did not develop the idea of a b.u.t.tress. On this site such an expedient would have saved an immense amount of work. In only one place in the canyon was a b.u.t.tress found. This was in the Casa Blanca ruin, shown in plate XLVII.
There is no doubt that in this place the b.u.t.tress was used with a full knowledge of its principles, and but little doubt that the idea was imported at a late, perhaps the latest, period in the occupancy of that site. Had it been known before, it would have been used in other places where there was great need for it, not so much to prevent the slipping of walls as to supersede the construction of walls 4 feet thick or more, and to strengthen outside walls which were likely to give way at any time from the outward thrust upon them.
Altogether the constructive expedients employed in De Ch.e.l.ly suggest the introduction of plans and methods adapted to other regions and other conditions into a new region with different requirements, and that occupancy of the latter region did not continue long enough to conform the methods to the new conditions.
KIVAS OR SACRED CHAMBERS
The kivas, or estufas as they formerly were called, are sacred chambers in which the civil and religious affairs of the tribe are transacted, and they also form a place of resort, or club, as it were, for the men.
Their functions are many and varied, but as this subject has already been discussed at length[17] it need not be enlarged upon here. In Tusayan the kivas are rectangular and separated from the houses; in Zuni and in some other pueblos they are also rectangular, but are incorporated in the house cl.u.s.ters--a feature doubtless brought about by the repressive policy of the Spanish monks. In some of the pueblos, as in Taos, they are circular, and in many of the older ruins the same form is found. In the large ruins of Chaco canyon the kivas occur in groups arranged along the inner side of the rooms; always, where the ground plan is such as to permit it, arranged on the border of an inner court.
In Canyon de Ch.e.l.ly the kivas are always circular and are placed generally on the outer edge of the settlement, which is usually the front.
[Footnote 17: 8th Ann. Rept. Bur. Eth., "A study of Pueblo architecture in Tusayan and Cibola," by Victor Mindeleff; Washington, 1891.]
As the function of the kivas is princ.i.p.ally a religious one, they are found only in permanent villages where religious ceremonies were performed. They are never found in subordinate settlements, or farming villages, or outlooks, unless such settlements came to be inhabited all the year--in other words, until they became permanent villages. The habits and requirements of the Pueblo people make it essential that a permanent village should have one or more kivas, and we have in the presence of these structures a criterion by which the character of a village or ruin may be determined. As the kivas in De Ch.e.l.ly are always circular, they can generally be easily distinguished.
The circular kiva is unquestionably a survival in architecture--a relic of the time when the Pueblo people dwelt in circular lodges or huts--and its use in conjunction with a rectangular system entailed many difficulties and some awkward expedients to overcome them. The main problem, how to use the two systems together, was solved by inclosing the circular chamber in a rectangular cell, and this expedient aided in the solution of the hardly less important problem of roofing. The roof of the kiva was the roof of the chamber that inclosed it.
It seems to have been a common requirement throughout the pueblo country that the kiva should be wholly or partly underground. So strong was this requirement in Tusayan that the occurrence of natural clefts and fissures in the rock of the mesa top has dictated the location of the kivas often at some distance from the houses. But in De Ch.e.l.ly there were some sites where the requirement could not be filled without extensive rock excavation wholly beyond the power of the builders. Here then it seems that other requirements were strong enough to overcome the ceremonial necessity for partly subterranean structures, for examples of that kind are comparatively rare. In all of the ruins on the canyon bottom the requirement could be filled, and as many of the villages on defensive sites were constructed after the site itself had been partly filled up with loose debris, it could also be filled in those cases.
There are also instances where the bottom of the kiva rests directly on the rock, while outside the walls the site was covered deep with artificial debris. But it would be difficult to determine what was the surface of the ground when the kiva was in use.
The size and character of the kivas in De Ch.e.l.ly, and their relations to the other rooms about them, are shown in the ground plans preceding.
Some have walls still standing to a height of 6 feet above the ground, but this could not have been the total height. Dr H. C. Yarrow, U.S.A., in 1874 examined one of the five large circular kivas in Taos. He states[18] that it was 25 or 30 feet in diameter, arched above, and 20 feet high. Around the wall, 2 feet from the ground, there was a hard earthen bench, and in the center a fireplace about 2 by 3 feet.
[Ill.u.s.tration: Fig. 70--Part of a kiva in ruin No. 31.]
Entrance to the kivas is invariably from the roof by a ladder. This appears to be a ceremonial requirement. Doorways at the ground level are not only unknown, but also impracticable; but in De Ch.e.l.ly there are some puzzling features which might easily be mistaken for such doorways.
The princ.i.p.al kiva in the ruin, which occurs at the point marked 10 on the map, and described above (page 123, figure 24), is on the edge of the ledge, and its outer wall is so close as to make a pa.s.sage difficult, although not impossible. At the point where the curved wall comes nearest the cliff there is a narrow gap or opening, not more than 15 inches wide. In front of this there appears to be a little platform on the sloping rock, 2 feet long, 10 inches wide, and now about a foot high. At first sight this would be taken for a doorway so arranged that access to the kiva could be obtained only from below; but a closer examination shows that this was probably only what remains of a chimney-like structure, such as those described later.
[Footnote 18: Wheeler Survey Reports, vol. VII, Archaeology, p. 327.]
In ruin 31 there is another example. The kiva here was about 20 feet in diameter, with rather thin walls smoothly plastered inside. On the inner side the walls are from 3 to 5 feet high; outside they are generally flush with the ground. The kiva is not a true circle, but is slightly elongated north and south. On the south side, nearest the edge of the ledge, there is an opening, shown in figure 70. The opening is 6 feet 3 inches wide, and the ends of the curved walls terminate in smoothly finished surfaces. In front of it there are remains of two walls, about a foot apart, and so arranged as to form an apparent pa.s.sageway into the interior of the kiva. These seem to be a kind of platform, like that just described, but close inspection shows the walls, which can be traced to within 6 inches of the inner wall of the kiva. This also may be the remains of a chimney-like structure. There are other points in the canyon where the same feature occurs, but in none of them is the evidence of an opening or doorway more definite than in the examples described.
[Ill.u.s.tration: Fig. 71--Plan of part of a kiva in ruin No. 10.]
The masonry of the kivas is always as good as that of any other structure on the site, and generally much better. The walls are usually ma.s.sive; sometimes they are 3 feet thick in the upper part and 4 feet in the lower portion, where the bench occurs. In a few cases the kiva has an upper or second story, but when this occurs no attempt is made to preserve the circular form, and the upper rooms are really rectangular with much rounded corners. Plate XLIX shows a second-story kiva wall in Mummy Cave ruin, and plate LXIII one in ruin No. 10 in De Ch.e.l.ly. The latter occurs over the princ.i.p.al kiva, and the walls which are still standing on the north and west sides are approximately straight, but the corners are much rounded. Figure 71 is a detailed plan of part of the kiva, showing the arrangement of the upper walls. The kiva walls are about 18 inches thick. On the north side the upper wall is supported by a heavy beam, part of which is still in place. Under the north-east corner of the upper room there is a little triangular s.p.a.ce formed by a short connecting wall, shown on the plan. This is really a flying wall, covering only the upper portion of the s.p.a.ce, and its purpose is not clear, as the opening left is not large enough to permit the pa.s.sage of a person, and was available only from the second story.
Apparently the greatest care was bestowed on the construction and finish of the kivas. The exterior of the circular wall is often rough and unfinished, but this is probably because the whole structure was generally inclosed within rectangular walls. The interior was plastered, often with a number of coats. The southern kiva in ruin No. 10 shows a number of these on its interior surface, applied one after another, and now forming a plastering nearly three-quarters of an inch thick. In its section 18 distinct coats can be counted, separated one from the other by a thin film of smoke-blackened surface. The kiva in ruin No. 16 has 4 or 5 coats, that in ruin No. 31 shows at least 8. In the last example the last coat was not decorated, but some of the underlying ones were.
Kivas are used, princ.i.p.ally in the autumn and winter, when the farming season is over and the ceremonies and dances take place. It is probable, therefore, that each coat of plaster means at least a year in the history of the kiva, which would indicate that some of the sites were occupied about twenty years. But Mr Frank H. Cushing has observed in Zuni a ceremony, part of which is the refinishing of the kiva interior, and this occurs only once in four years. This would give a maximum occupancy of about eighty years to some of the kivas; the ruins as a whole would hardly justify an hypothesis of a longer occupancy than this. In Tusayan the interior of the kiva is plastered by the women once every year at the feast of Powamu (the fructifying moon).
