30 SARAWAK ETHNOGRAPHICAL COLLECTION. 



Catalogue No. 733. Dr. G. D. Haviland (P. 1890). From 

 the head of the Tengoa valley. 



h. Bird-Calls. 



Though these are not musical instruments in the strictest 

 sense of the word they deserve notice here since morpholo- 

 gically at least they are musical instruments. I know of two 

 distinct forms of bird-calls used in Borneo : — 



1. Kyan— Bulo wok. (Plate VIII fig. 9.) 



These are constructed on the same principle as the bamboo 

 flageolets of type D, but they are made of a larger species of 

 bamboo and are much shorter. With these the Kyans imitate the 

 cry of the owl Ninox scutulata and the cry of the gibbon Hijlo- 

 bates mulleri. 



a. Distal end open, proximal end closed by the natural 

 septum, the bamboo not cut flush with this but projecting almost 

 as far proximad of it as it does distad ; in this proximal portion 

 a large hole is bored, the very large sound-hole is bored just 

 distad of the septum and leading to it from the other hole on 

 the outside is a wide gutter or groove roofed over with a slip 

 of bamboo luted on with dammar. The instrument is decorated 

 with a characteristic Kyan design carved in low relief . Length 

 12-7 cm. ; diam. 5*1 cm. ; diam. of sound-hole 2*3 cm. 



Catalogue No. 1289. [Acquired by exchange from Dr. C. 

 Hose. ix. 03]. From the Baram river. 



b. The distal end open, proximal end closed by the natural 

 septum. The bamboo projected considerably proximad of this but 

 nearly all has been cut away leaving only a small flange 

 in which a hole is bored (see figure) ; the sound hole and direc- 

 tive duct as in the preceding example. The instrument, which 

 is not ornamented in any way, is illustrated on Plate VIII, 

 fig. 9. Length (including flange) 13*5 cm.; diam. 4*9 cm. 



Catalogue No. 1290. [Acquired by exchange from Dr. C. 

 Hose ix 03]. From the Baram river. 



The Sea-Dyaks, Kenyans, Kadyans and Muruts employ an 

 interesting form of bird-call for attracting within reach pigeons
