3It is believed that the thatch must be allowed to turn yellow before the house is completed.
When the first post is put into the ground, a sacrifice is frequently made and a part of the victim's blood is poured upon the base of the post. As soon as the roof and floor have been constructed, a formal sacrifice of a chicken is made to the special divinities under whose protection the family is thought to be. The chicken must be of the color that is pleasing to these deities. An interesting feature of this ceremony is that the center of the floor, the place intended for the doorway, and one or more of the posts, are lustrated with the blood of the victim.
STRUCTURE OF THE HOUSE
THE MATERIALS
The materials for the house are taken from the surrounding forest and are generally of a light character. It is only in the erection of a house4 for defense that more substantial materials are employed.

THE DIMENSIONS AND PLAN OF CONSTRUCTION
In height from the ground to the floor the house may vary from 1.50 to 8 meters, though a structure of the latter height is infrequent. In size it may be between 2 by 3 meters and 5 by 8 meters, but as a rule it is nearer to the former than to the latter figures. Rectangular in form, it is built upon light posts varying in number from 4 to 16, the 4 corner ones being larger and extending up to support the roof. Four horizontal pieces attached to these corner posts and, supported by several of the small posts, form, together with a few joints, the support for the floor. In order to give more rigidity to the building and to render the floor stronger, the joints are supported by several posts, these last being propped by braces set at an angle of about 45°. In the case of a house built for defense, the number of supports and crosspieces is such that the enemy would find it impossible to hack it down.
