Six beams were used in the roof, laid between the north and south walls.

There were rafters of two different lengths, being set in an angle of about ten degrees to each other.

The west wall contained twelve pockets, doubtless the cavities in which the rafters had rested.

They were, on an average, three inches in diameter, and ran in some six inches, slanting downward in the interior.

The east wall was found to contain upright poles and horizontal slats, forming a framework for the building material.
