and always rests upon
the platform, never upon the lower floor, and in their traditional
genesis it is stated that the people climbed up from the third house
(stage) by a ladder of pine, and through such an opening as the kiva
hatchway; only most of the stories indicate that the opening was round.
The outer air is the fourth world, or that now occupied.

There are occasional references in the Tusayan traditions to circular
kivas, but these are so confused with fantastic accounts of early mythic
structures that their literal rendition would serve no useful purpose in
the present discussion.

_Typical measurements._--The following list is a record of a number
of measurements of Tusayan kivas collected by Mr. Stephen. The wide
difference between the end measurements of the same kiva are usually
due to the interior offsets that have been noticed on the plans, but
the differences in the lengths of the sides are due to irregularities
of the site. The latter differences are not so marked as the former.
