The two long beams in the middle are twin ridge-timbers, which are supported in the rear, as in the front, by a transverse beam resting on two uprights. At the extreme right and left are the eaves-timbers. The longitudinal and circular flutes of the columns are laboriously produced by means of a small hand-adze of primitive form. This frame is at the village Memkumlis. Another view is given in the illustration facing page 36. Kwakiutl houses are discussed on page 6.
