BURU. 



This large island lies about 80 miles south-south-west of the 

 Obi Islands, 50 miles south-east of the Sula Islands and a lesser 

 distance west of Ceram and Amboina. 



The double outrigger is employed for most purposes ; ordinary 

 dugouts without outriggers are used in quiet water, while for heavy 

 work beamy plank-built true boats are employed. 



By far the most numerous outrigger is that with U-shaped 

 secondaries — the Biiru type — generally withies, rarely stout rattan. 

 The float is variable, either composed of one, two, or even three 

 sago palm leaf-stalks or of a pole of light wood flattened below 

 and convex above or else of a suitable length of bamboo. Such 

 canoes have hulls made of comparatively short dugouts, usually 

 with a washboard added, together with high projecting stern and 

 stem pieces; some have a narrow slab-sided dugout for a basis; 

 the others are flared and these are much wider amidships, as the 

 wash-board continues and emphasizes the flare of the sides.
