 Bokoe, Central Celebes. 



The Koro, which is the largest river of Central 

 Celebes, is bridged at several places by rattan hanging 

 bridges more than two hundred feet long; this one 

 has as its mainstay, five large rattans each about three 

 centimeters in diameter. Other smaller rattans are 

 arranged as a hand rail.

 The curious sail is made from the fiber of the banana tree, loosely 

 woven but nevertheless quite durable.
