36 SARAWAK ETHNOGRAPHICAL COLLECTION. 



a length of bamboo is added to one or to both or the distal end 

 of one is obliquely truncated, thus practically reducing its length. 

 If in spite of these devices the pipes are still out of tune a 

 length of grass or wood splinter {adjok) is pushed up the drone- 

 pipe and moved up and down until the correct note is hit off. 

 Mr. Byrde informs me that one of the specimens just described 

 was cut to almost accurate lengths and required no tuning with 

 the adjok. 



c. Very similar to the two preceding specimens, the laki, 

 however, has only four stops about 3 centim. apart, the drone- 

 pipe is pierced with five stops but they have all been plugged 

 up with wax. The distal ends of the pipes are cut square and 

 are not fitted with lengths of bamboo. Length of laid 43 5 

 cm. ; length of drone-pipe 38*7 cm.

From Picbing village, Upper Sadong. Known as Serune. 

 The performer on this instrument tuned it by thrusting a piece of 

 grass up the drone-pipe and moving it up and down until he hit 

 off the correct note. As the vibrating tongues are cut at some 

 little distance from the proximal ends of the pipes, these have 

 to be thrust well into the mouth ; a continuous blast was given 

 by inhaling with the nostrils and blowing into the instrument 

 with the mouth simultaneously, just as in using the chemist's 

 blowpipe. 



The Land-Dyaks of Quop, Sarawak river, also play these 

 pipes ; they always leave the proximal ends open and close them, 

 when playing, with the tongue, the ' beating' reed is cut much 

 closer to the proximal end than in Krokong or Sadong examples ; 

 sometimes three pipes are bound together, two being drone- 

 pipes. A good set will be kept in a bamboo full of water, as the 

 pipes are generally made from fresh-cut bamboo stems and 

 when they become dry the tongues will not vibrate effectively. 



Class VII. 



MOUTH-ORGANS — with single 'free' reed. (Plate III fig. 9). 



These instruments, which are figured in almost every book 

 on Borneo, consist of a hollowed gourd with a long neck the
