Another difference indicating development is the decrease in the number of kivas, and the construction of a single very large kiva in the middle of the building. Its size suggests at once that the individual clan organization of cliff-dwelling days had here given place to a single priestly fraternity, sociologically a marked advance. Drawing parallels with the better-known customs of other primitive people, we are at liberty, if we please, to infer similar progress in other directions. The original primitive communism was developing naturally, though doubtless very slowly, into something akin to organized society, probably involving more complicated economic relationships in all departments of living.

While their masonry did not apparently improve in proportion, Far View House shows increase in the number and variety of the decorative figures incised on hewn stones. The spiral, representing the coiled serpent, appears a number of times, as do many combinations of squares, curves, and angles arranged in fanciful design, which may or may not have had symbolic meanings.

A careful examination of the neighborhood discloses few details of the irrigation system, but it shows a cemetery near the southeast corner of the building in which the dead were systematically buried.

Large numbers of minor antiquities were found in this interesting structure. Besides the usual stone implements of the mason and the housekeeper, many instruments of bone, such as needles, dirks, and bodkins, were found. Figurines of several kinds were unearthed, carved from soft stone, including several intended to symbolize Indian corn; all these may have been idols. Fragments of pottery were abundant, in full variety of form, decoration, and color, but always the most ancient types. Among the bones of animals, the frequency of those of rabbits, deer, antelope, elk, and mountain-sheep indicate that meat formed no inconsiderable part of the diet. Fabrics and embroideries were not discovered, as in the cliff-dwellings, but they may have disappeared in the centuries through exposure to the elements.

Far View House may not show the highest development of the Mummy Lake cluster of pueblos, and further exhumations here and in neighboring groups may throw further light upon this interesting people in their gropings from darkness to light. Meantime, however, returning to the neighborhood of the cliff-dwellings, let us examine a structure so late in the history of these people that they left it unfinished.

Sun Temple stands on a point of Chapin Mesa, somewhat back from the edge of Cliff Canyon, commanding an extraordinary range of country. It is within full view of Cliff Palace and other cliff-dwellings of importance and easy of access. From it, one can look southward to the Mancos River. On every side a wide range of mesa and canyon lies in full view. The site is unrivalled for a temple in which all could worship with devotion.

When Doctor Fewkes, in the early summer of 1915, attacked the mound which had been designated Community House under the supposition that it covered a ruined pueblo, he had no idea of the extraordinary nature of the find awaiting him, although he was prepared from its shape and other indications for something out of the usual. So wholly without parallel was the disclosure, however, that it was not till it was entirely uncovered that he ventured a public conjecture as to its significance. The ground-plan of Sun Temple is shaped like the letter D. It encloses another D-shaped structure occupying nearly two-thirds of its total area, within which are two large kivas. Between the outer and the inner D are passages and rooms, and at one end a third kiva is surrounded by rooms, one of which is circular.

Sun Temple is also impressive in size. It is a hundred and twenty-one feet long and sixty-four feet wide. Its walls average four feet in thickness, and are double-faced, enclosing a central core of rubble; they are built of the neighborhood sandstone. The masonry is of fine quality. This, together with its symmetrical architectural design, its fine proportions, and its many decorated stones, mark it the highest type of Mesa Verde architecture.
