The walls, eight to nine inches thick, built of a mixture of clay and earth, were fairly well preserved in places.

In one house, which had unusually solid compartments, the walls were twenty, and in some places even thirty-three, inches thick.

Here nothing could be found, either in the rooms or by excavating below the floor.

The same conventional doorways were met with in all the mound houses, but there was hardly any trace Of woodwork.
Excavations in one of the mounds near our camp disclosed very interesting composite structures.

One part of the walls consisted of large posts set in the ground and plastered over, forming a stuccoed palisade.
