mately arranged and arise from the dent of the heart 

 The petiole supporting the leaf is fairly long and hairy. 



The plant twines around other plants for support. It 

 never develops prop roots. The small male and female 

 flowers are never borne on the same plant. The fruit is 

 small. 



DISTRIBUTION. 



The plant is generally found in thickets, waste places, 

 or along the banks of streams and irrigation ditches in 

 many places throughout the Philippines. 



PREPARATION. 



The best material is obtained from the older portion of 

 the vine, which is bare of leaves. 



The most expedient way to prepare the material is to 

 boil the stem for about two hours. The outer layer with 

 its adhering tissue is then easily separated from the inner 

 part and thrown away. The material is then dried in the 

 sun and smoothed with sand paper. It is yellowish white 

 in color and from 2.5 to 3.5 mm. in diameter. 



The Albay Industrial Bulletin No. 4 of December 5, 1911, 

 gives two other methods of preparing the stem which result 

 in a whiter and stronger material, but require more time: 



Remove the bark without boiling in the same way as is done with 

 bacog (air roots). This method requires very careful work as the 

 bark breaks easily. 



Scrape off the bark without boiling the material, being careful 

 not to injure the woody part. Dry in the sun and sandpaper well. 



USES. 



Pamago is a good material for weavers of baskets.
