Mummy Lake is not a lake and no mummies were ever found there. This old-time designation applies to an artificial depression surrounded by a low rude stone wall, much crumbled, which was evidently a storage reservoir for an irrigation system of some size. A number of conspicuous mounds in the neighborhood suggest the former existence of a village of pueblos dependent upon the farms for which the irrigation system had been built. One of these, from which a few stones protruded, was excavated in 1916 by Doctor Fewkes, and has added a new and important chapter to the history of this people. This pueblo has been named Far View House. Its extensive vista includes four other groups of similar mounds. Each cluster occurs in the fertile sage-brush clearings which bloom in summer with asters and Indian paint-brush; there is no doubt that good crops of Indian corn could still be raised from these sands to-day by dry-farming methods. Far View House is a pueblo, a hundred and thirteen feet long by more than fifty feet wide, not including a full-length plaza about thirty-five feet wide in which religious dances are supposed to have taken place. The differences between this fine structure and the cliff-cities are considerable. The most significant evidence of progress, perhaps, is the modern regularity of the ground-plan. The partitions separating the secular rooms are continuous through the building, and the angles are generally accurately right angles. The pueblo had three stories. It is oriented approximately to the cardinal points and was terraced southward to secure a sunny exposure. The study of the solar movements became an advanced science with these people in the latter stages of their development. It must be remembered that they had no compasses; knowing nothing of the north or any other fixed point, nevertheless there is evidence that they successfully worked out the solstices and planned their later buildings accurately according to cardinal points of their own calculation. 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.
