John M. Garvan, The Manóbos of Mindanáo
“ The bowstring is nearly always a strip of rattan about 3 millimeters broad. This is attached to the lower end of the stock by a simple series of loops. To the upper extremity it is attached by a loop that slips along the stock into the upper notch when the bow is strung for shooting. It is needless to remark that the bowstring is about 2 or 3 centimeters shorter than the stock, which in the moment of stringing must be bent to enable the upper extremity of the string to reach the upper notch and thereby acquire a sufficient tension to propel the arrow. ”
