VOL. XII, 



hoisting sail the tripod is first erected, the two paired legs being 

 each provided with a slot near the foot, which is slipped over the 

 laterally projecting end of the cross-bar of the tabernacle. The 

 unpaired leg has similarly a perforation in the foot, but here it 

 runs fore and aft. This slips over a projecting peg on the foreside 

 of a thwart half way between the tabernacle and the stem. 

 Properly adjusted such a tripod is quite stiff and requires no 

 stays. When the mast is up, a loop placed near the mid-length 

 of the upper yard of the sail is slipped over one arm of the Y-peg 

 at the mast head, a boatman holding up vertically the rolled up 

 sail till he manages to hitch the loop over the peg. The sail is then 

 unrolled and the sheet made fast astern. The fore end of the boom 

 is secured to the same thwart to which the unpaired mast leg is 

 attached or else to one right at the stem. In heavy weather the 

 lower edge of the sail is partially rolled up around the boom and 

 the yard lashed half way or so up the mast. 



(b) The East Halmaheira or Buli variety of plank-built outrigger, 

 hails chiefly from the ports of Tobelo, Kao, and Buli on the eastern 

 coast of Halmaheira. Usually the planked hulls are built up upon 

 a very narrow dugout base which serves the purpose of a keel ;

indeed at Kao the direct evolution of this design from the ordinary 

 small outrigger dugout is clearly exhibited in the perfect gradation 

 of all stages, from the plain dugout without any added pieces 

 through a stage where a single wash-strake is added together 

 with prominent stem and stern pieces, up to large boats built up of 

 3 and 4 or more strakes, and possessing a fairly roomy cabin. 

 Some have a nearly straight keel, but many of the medium-sized 

 Kao ones have the dugout keel portion strongly curved, with stem 

 and stern posts continued upwards with inordinate sheer as shown 

 in figure 23. One such boat measured on the Buli beach was 20 

 feet long overall, 4% feet wide amidships, and ~$V\ feet deep. This
