and are ornamented with irregularly drawn designs in black paint ([fig. 1], e). Many of the patterns suggest basketry prototypes.

All in all, post-Basket Maker pottery, judging from the few specimens so far recovered, is surprisingly well made; so well as to raise the suspicion that an earlier stage still awaits discovery. Hints of such a stage have, indeed, been found in the form of heavy clay dishes, tempered with shredded juniper bark, unbaked but distinctly superior in size and workmanship to the Basket Maker product. These specimens have turned up in post-Basket Maker sites, but in caves stratigraphically so confused that it is still uncertain whether they antedated, or were contemporaneous with, the more highly-perfected post-Basket Maker wares. They are too crude, however, to be considered the direct forerunners of post-Basket Maker pottery. If the development took place in the San Juan, one step at least is still lacking. These questions will be answered by further work of the sort now being carried on by Guernsey in the Kayenta country and by Morris in the Canyon del Muerto.

From post-Basket Maker times down to the present day, however, the development of Southwestern pottery can already be outlined with considerable confidence. The next stage is usually called the pre-Pueblo. It is marked by further improvements in house-building, by the introduction of cranial deformation, and by certain innovations in ceramics. It had been the custom with the post-Basket Makers (as among many primitive people) to build up their vessels by adding to the growing walls successive rings of clay. When the process was complete and the sides had reached the requisite height, all trace of the rings was obliterated by rubbing down the surface. In the interiors of some post-Basket Maker pieces, however, with orifices so small that a smoothing tool could not be introduced, there were left the telltale junction-lines between the structural rings. In pre-Pueblo times it became the fashion purposely to leave unsmoothed the last few rings at the necks of certain small cooking vessels ([fig. 2], a; pl. 2, a). This was the beginning of the elaborate coiled or corrugated technique, later so widely used.

Pre-Pueblo black-on-white ware takes the form of bowls, pitchers, ladles, small jars, and ollas. Its paste is hard, is less heavily tempered than post-Basket Maker paste, and the surfaces of the pieces are better smoothed. The decoration is characterized by boldness and dash, the brushwork being correspondingly hasty. The lines are of irregular width, nor was care exercised that the junctions of strokes should be accurate. As is shown by the accompanying drawings ([fig. 2], b, c), the commonest elements are the stepped figure and the triangle, both often emphasized by sets of widely spaced thin lines which follow the outer edges of the basic patterns.

The transition between the pre-Pueblo and the Pueblo was evidently a gradual one. There was no violent break, either in culture or in physical type; and so it is hard to say just where the dividing line should be drawn. The introduction of indented corrugated pottery, however, forms a convenient milepost on the road of ceramic progress. The change was brought about as follows: the plain, broad rings of pre-Pueblo ware were replaced by a continuous thin fillet of clay applied spirally; the junctions between the successive laps of the fillet were left unobliterated, not only at the neck, but over the entire vessel; and the fillet itself was also notched or pinched or otherwise indented to produce various ornamental effects ([pl. 2], b, c). Thus was made the well-known coiled or corrugated cooking-ware so characteristic of all the archaic true Pueblo ruins, a style introduced at about the same time as the development of the above-ground rectangular living-room, the clustered method of building, and the use of horizontally coursed masonry, all elements that are commonly recognized as typical of true Pueblo culture. The earliest varieties of Pueblo pottery are imperfectly known, for little work has so far been done in the small and often nearly obliterated mounds that mark the house-sites of the first pueblo-dwellers. It is certain, however, that in the San Juan and Little Colorado drainages there was a strong growth in corrugated ware. This technique was experimented on and played with. The variety and even virtuosity of the results are extraordinary: waved coiling, pinched coiling, incised coiling, and all manner of indenting were practised ([pl. 2], b). The black-on-white ware evidently did not advance so rapidly, the vessels, to judge from the sherds, were not particularly symmetrical as to shape or notable as to finish. The decoration ran to hachure in wavy lines and to poorly drawn spiral figures.

As I have just said, little is known of the early Pueblo sites. The period which they represent, however, was undoubtedly a long one. The date of its beginning is entirely problematical, nor can we even say with any assurance when it ended, but the probabilities are that as early as the opening of the Christian era the Pueblos had begun to gather together into larger settlements, to develop the closely-knit community life, and the many-storied terraced style of architecture which typify the golden age of their existence. Between that time and 1000 or 1100 A.D. the more or less uniform early culture split up into distinct and often highly specialized local sub-cultures, each of which followed its own line of growth in house-building, pottery-making, and the minor arts. It was during this general phase of Southwestern history that there came into being the great pueblos and cliff-dwellings that housed entire villages: Pueblo Bonito and the other Chaco Canyon towns; the cliffhouses of the Mesa Verde and of the Kayenta country; the enormous adobe constructions such as Casa Grande on the Gila and Casas Grandes in Chihuahua.
