The earliest form of ladder among the pueblos was probably a notched log, a form still occasionally used. Figures 45 and 46 illustrate examples of this type of ladder from Tusayan.
A notched ladder from Oraibi, made with a modern axe, is shown. This specimen has a squareness of outline and an evenness of surface not observed in the ancient examples. The ladder from Mashongnavi, illustrated on the left of [Fig. 46], closely resembles the Oraibi specimen, though the workmanship is somewhat ruder. The example illustrated on the right of the same figure is from Oraibi. This ladder is very old, and its present rough and weatherbeaten surface affords but little evidence of the character of the implement used in making it.
The ladder having two poles connected by cross rungs is undoubtedly a native invention, and was probably developed through a series of improvements on the primitive notched type. It is described in detail in the earliest Spanish accounts. [Fig. 47] illustrates on the left the notched ladder, and on the right a typical two-pole ladder in its most primitive form. In this case the rungs are simply lashed to the uprights. The center ladder of the diagram is a Mandan device illustrated by Mr. Lewis H. Morgan.[6] As used by the Mandans this ladder is placed with its forked end on the ground, the reverse of the Pueblo practice. It will readily be seen, on comparing these examples, that an elongation of the fork which occurs as a constant accompaniment of the notched ladder might eventually suggest a construction similar to that of the Mandan ladder reversed. The function of the fork on the notched ladder in steadying it when placed against the wall would be more effectually performed by enlarging this feature.
At one stage in the development of the form of ladder in common use to-day the rungs were laid in depressions or notches of the vertical poles, resembling the larger notches of the single ladder, and then lashed on with thongs of rawhide or with other materials. Later, when the use of iron became known, holes were burned through the side poles. This is the nearly universal practice to-day, though some of the more skillful pueblo carpenters manage to chisel out rectangular holes. The piercing of the side poles, particularly prevalent in Zuni, has brought about a curious departure from the ancient practice of removing the ladder in times of threatened danger. Long rungs are loosely slipped into the holes in the side pieces, and the security formerly gained by taking up the entire ladder is now obtained, partially at least, by the removal of the rungs. The boring of the side pieces and the employment of loose rungs seriously interferes with the stability of the structure, as means must be provided to prevent the spreading apart of the side pieces. The Zuni architect has met this difficulty by prolonging the poles of the ladder and attaching a cross piece near their upper ends to hold them together. As a rule this cross piece is provided with a hole near each end into which the tapering extremities of the poles are inserted. From their high position near the extremities of the ladders, seen in silhouette against the sky, they form peculiarly striking features of Zuni. They are frequently decorated with rude carvings of terraced notches. Examples of this device may be seen in the views of Zuni, and several typical specimens are illustrated in detail in [Pl. XCVIII]. The use of cross pieces on ladders emerging from roof openings is not so common as on external ones, as there is not the same necessity for holding together the poles, the sides of the opening performing that office.
There are two places in Zuni, portions of the densest house cluster, where the needs of unusual traffic have been met by the employment of double ladders, made of three vertical poles, which accommodate two tiers of rungs. The sticks forming the rungs are inserted in continuous lengths through all three poles, and the cross pieces at the top are also continuous, being formed of a single flat piece of wood perforated by three holes for the reception of the tips of the poles. In additional to the usual cross pieces pierced for the reception of the side poles and rudely carved into ornamental forms, many temporary cross pieces are added during the harvest season in the early autumn to support the strips of meat and melons, strings of red peppers, and other articles dried in the open air prior to storage for winter use. At this season every device that will serve this purpose is employed. Occasionally poles are seen extending across the reentering angles of a house or are supported on the coping and rafters. The projecting roof beams also are similarly utilized at this season.
Zuni ladders are usually provided with about eight rungs, but a few have as many as twelve. The women ascend these ladders carrying ollas of water on their heads, children play upon them, and a few of the
