Immense numbers of these storage cists are found in the canyon, some of them with masonry so roughly executed that it is difficult to discriminate between the old pueblo and the modern Navaho work. Sometimes these cists or small rooms form part of a village, more often they are attached to the cliff outlooks, and not infrequently they stand alone on sites overlooking the lands whose product they contained. It is probable that many of the cliff outlooks themselves were used quite as much for temporary storage as for habitations during the farming season. These two uses, although quite distinct, do not conflict with each other. Doubtless many excellent sites, now marked only by the remains of storage cists, were occupied also during the summer as outlooks without the erection of any house structures. Some of the modern pueblos now use temporary shelters of brush for outlooks. It is not meant that the crops when gathered were placed in these cists and kept there until used. The harvest was, as a rule, permanently stored in the home villages, and the cists were used only for temporary storage. Doubtless the old practice resembled somewhat that followed by the Navaho today. The harvest is gathered at the proper time and what is not eaten at once is hidden away in cists of old or modern construction. If it is well hidden, the grain may remain in the cists for a long time if not withdrawn for consumption; but as a rule it is taken away a few months later.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.
