The ethnographical record can supply
many data that do not exist in the archae-
ological record. The roof construction
of this Oayana maloca (near Lawa River,
French Guiana) informs us on such con-
structions. Studying many of these modern
structures supplies data on the way pre-
Columbian houses that have comparable
floor-plans, such as excavated in St. Eu-
statius, were constructed.
