�KIDDER] HISTORIC RUINS IN SAN JUAN VALLEY, N. M. 325
of historic date was afforded by the finding of cow and sheep bones in the rubbish.
The hogan-like structures are built in every case within the enclosing defensive walls, close to the stone houses. They are much decayed, but all show the same general features, being circular in ground plan, eight to ten feet in diameter, and made of cedar logs set in the ground and meeting at the top tipi-style (fig. 18). They seem to have been covered with sod or earth, and to have been entered by short, low pas- sageways of stone roofed with split cedar. From the condition of their beams they ap- pear to be contemporaneous with the stone houses.

All surfaces are nicely smoothed. Decorated portions have thick yellowish and
