Figure 26.—Contact joins of eave batten (langolau):

a, set on edge, 3 inches wide by 1 inch thick—short pieces joined merely by contact of squared ends; b, oblique slant join; c, so'o mata sai join. At the slanted contacts the lashing from the thatch rafters passes over both elements but there is no special lashing to attach two individual pieces of the eave batten to each other.
