The outer side of this structure was always supported on piles; in fact, in many cases, the houses as well as the whole sidewalk were thus raised from the ground. This type of construction was necessitated by the sloping sites of the villages, but had the added advantage of being a protection against attack. The villages differed in size from insignificant settlements of three to four houses, to ones with twenty or thirty, each con- taining several families.
