In constructing a Cahto house, a circular excavation about two feet deep was prepared, and in it, at the corners of a square were erected four forked posts. The front pair were a little taller than the other, so that the roof would have a slight pitch to the rear. The roof was so small that it was of much less importance in determining the final shape of the house than was the circularity of the base. The space between the posts were stuffed with bunches of long grasses, and slabs of wood and bark. An opening in the roof served to carry off smoke, and the doorway was a narrow opening in front from ground to roof. As many as three families occupied one of these little houses, with all persons cooking at the same fire. For summer camps, brush lean-tos were set up. The dog was the only domesticated animal.
