View, Cross-section, and Ground-plan of Mandan round house.
The extreme of variation consistent with adherence to the common principle was to be found in the shape and material of the houses. Those of the savage tribes were but sorry huts. The long house was used by the Powhatans and other Algonquin tribes. The other most highly developed type may be illustrated by the circular frame-houses of the Mandans.[85] These houses were from forty to sixty feet in diameter. Circular houses of the Mandans. A dozen or more posts, each about eight inches in diameter, were set in the ground, "at equal distances in the circumference of a circle, and rising about six feet above the level of the floor." The tops of the posts were connected by horizontal stringers; and outside each post a slanting wooden brace sunk in the ground about four feet distant served as a firm support to the structure. The spaces between these braces were filled by tall wooden slabs, set with the same slant and resting against the stringers. Thus the framework of the outer wall was completed. To support the roof four posts were set in the ground about ten feet apart in the form of a square, near the centre of the building. They were from twelve to fifteen feet in height, and were connected at the top by four stringers forming a square. The rafters rested upon these stringers and upon the top of the circular wall below. The rafters were covered with willow matting, and upon this was spread a layer of prairie grass. Then both wall and roof, from the ground up to the summit, were covered with earth, solid and hard, to a thickness of at least two feet. The rafters projected above the square framework at the summit, so as to leave a circular opening in the centre about four feet in diameter. This hole let in a little light, and let out some of the smoke from the fire which blazed underneath in a fire-pit lined with stone slabs set on edge. The only other aperture for light was the doorway, which was a kind of vestibule or passage some ten feet in length. Curtains of buffalo robes did duty instead of doors. The family compartments were triangles with base at the outer wall, and apex opening upon the central hearth; and the partitions were hanging mats or skins, which were tastefully fringed and ornamented with quill-work and pictographs.[86] In the lower Mandan village, visited by Catlin, there were about fifty such houses, each able to accommodate from thirty to forty persons. The village, situated upon a bold bluff at a bend of the Missouri river, and surrounded by a palisade of stout timbers more than ten feet in height, was very strong for defensive purposes. Indeed, it was virtually impregnable to Indian methods of attack, for the earth-covered houses could not be set on fire by blazing arrows, and just within the palisade ran a trench in which the defenders could securely skulk, while through the narrow chinks between the timbers they could shoot arrows fast enough to keep their assailants at a distance. This purpose was further secured by rude bastions, and considering the structure as a whole one cannot help admiring the ingenuity which it exhibits. It shows a marked superiority over the conceptions of military defence attained by the Iroquois or any other Indians north of New Mexico. Besides the communal houses the village contained its "medicine lodge," or council house, and an open area for games and ceremonies. In the spaces between the houses were the scaffolds for drying maize, buffalo meat, etc., ascended by well-made portable ladders. Outside the village, at a short distance on the prairie, was a group of such scaffolds upon which the dead were left to moulder, somewhat after the fashion of the Parsees.[87]
We are now prepared to understand some essential points in the life of the groups of Indians occupying the region of the Cordilleras, both north and south of the Isthmus of Darien, all the way from Zuñi to Quito. The Indians of the pueblos,—in the middle status of barbarism. The principal groups are the Moquis and Zuñis of Arizona and New Mexico, the Nahuas or Nahuatlac tribes of Mexico, the Mayas, Quichés, and kindred peoples of Central America; and beyond the isthmus, the Chibchas of New Granada, and sundry peoples comprised within the domain of the Incas. With regard to the ethnic relationships of these various groups, opinion is still in a state of confusion; but it is not necessary for our present purpose that we should pause to discuss the numerous questions thus arising. Our business is to get a clear notion in outline of the character of the culture to which these peoples had attained at the time of the Discovery. Here we observe, on the part of all, a very considerable divergence from the average Indian level which we have thus far been describing.
This divergence increases as we go from Zuñi toward Cuzco, reaching its extreme, on the whole, among the Peruvians, though in some respects the nearest approach to civilization was made by the Mayas. All these peoples were at least one full ethnical period nearer to true civilization than the Iroquois,—and a vast amount of change and improvement is involved in the conception of an entire ethnical period. According to Mr. Morgan, one more such period would have brought the average level of these Cordilleran peoples to as high a plane as that of the Greeks described in the Odyssey. Let us now observe the principal points involved in the change, bearing in mind that it implies a considerable lapse of time. While the date 1325, at which the city of Mexico was founded, is the earliest date in the history of that country which can be regarded as securely established, it was preceded by a long series of generations of migration and warfare, the confused and fragmentary record of which historians have tried—hitherto with scant success—to unravel. To develop such a culture as that of the Aztecs out of an antecedent culture similar to that of the Iroquois must of course have taken a long time.
It will be remembered that the most conspicuous distinctive marks of the grade of culture attained by the Cordilleran peoples were two,—the Horticulture with irrigation, and architecture with adobe. cultivation of maize in large quantities by irrigation, and the use of adobe-brick or stone in building. Probably there was at first, to some extent, a causal connection between the former and the latter. The region of the Moqui-Zuñi culture is a region in which arid plains become richly fertile when water from neighbouring cliffs or peaks is directed down upon them. It is mainly an affair of sluices, not of pump or well, which seem to have been alike beyond the ken of aboriginal Americans of whatever grade. The change of occupation involved in raising large crops of corn by the aid of sluices would facilitate an increase in density of population, and would encourage a preference for agricultural over predatory life. Such changes would be likely to favour the development of defensive military art. The Mohawk's surest defence lay in the terror which his prowess created hundreds of miles away. One can easily see how the forefathers of our Moquis and Zuñis may have come to prefer the security gained by living more closely together and building impregnable fortresses.
The earthen wall of the Mandan, supported on a framework of posts and slabs, seems to me curiously and strikingly suggestive of the incipient pottery made by surrounding a basket with a coating of clay.[88] When it was discovered how to make the earthen bowl or dish without the basket, a new era in progress was begun. So when it was discovered that an earthen wall could be fashioned to answer the requirements of house-builders without the need of a permanent wooden framework, another great step was taken. Possible origin of adobe architecture. Again the consequences were great enough to make it mark the beginning of a new ethnical period. If we suppose the central portion of our continent, the Mississippi and Missouri valleys, to have been occupied at some time by tribes familiar with the Mandan style of building; and if we further suppose a gradual extension or migration of this population, or some part of it, westward into the mountain region; that would be a movement into a region in which timber was scarce, while adobe clay was abundant. Under such circumstances the useful qualities of that peculiar clay could not fail to be soon discovered. The simple exposure to sunshine would quickly convert a Mandan house built with it into an adobe house; the coating of earth would become a coating of brick. It would not then take long to ascertain that with such adobe-brick could be built walls at once light and strong, erect and tall, such as could not be built with common clay. In some such way as this I think the discovery must have been made by the ancestors of the Zuñis, and others who have built pueblos. After the pueblo style of architecture, with its erect walls and terraced stories, had become developed, it was an easy step, when the occasion suggested it, to substitute for the adobe-brick coarse rubble-stones embedded in adobe. The final stage was reached in Mexico and Yucatan, when soft coralline limestone was shaped into blocks with a flint chisel and laid in courses with adobe-mortar.
The pueblos of New Mexico and Arizona are among the most interesting structures in the world. Several are still inhabited by the descendants of the people who were living in them at the time of the Spanish Discovery, and their primitive customs and habits of thought have been preserved to the present day with but little change. The long sojourn of Mr. Cushing, Mr. Cushing at Zuñi. of the Bureau of Ethnology, in the Zuñi pueblo, has already thrown a flood of light upon many points in American archæology.[89] As in the case of American aborigines generally, the social life of these people is closely connected with their architecture, and the pueblos which are still inhabited seem to furnish us with the key to the interpretation of those that we find deserted or in ruins, whether in Arizona or in Guatemala.
