RESINS, TERPENES, PERFUMES, EDIBLE NUTS, AND VEGETABLE OILS OTHER THAN 



COCONUT OIL 



[See prints in photograph stand.] 



Resins and terpenes. — Elemi, balao, apitong, almaciga, and copal find 

 application in the varnish industry and in the making of resin soaps. 



Perfumes. — The essential oils of ylang-ylang, champaca, vetiver, lemon 

 grass, orange, cinnamon, and ginger are used in the perfume industry, and 

 several of them are used in the manufacture of nonalcoholic beverages and 

 fruit flavors. 



Edible nuts. — The pili nut is very rich in oil. It is very delicious and 

 has a flavor similar to that of the Brazil nut. 



Vegetable oils other than coconut oil. — Important vegetable oils, besides 

 coconut oil, are produced in the Philippine Islands from the physic nut, 

 peanut, and pili nut and from the seeds of lumbang, kapok, cato, cashew, 

 castor bean, and cotton. Lumbang oil has good drying qualities and is 

 used in the varnish and the linoleum trades. Other oils now little known 

 may prove to be of commercial value.

COMMERCIAL PLANT PRODUCTS 



[See prints in photograph stand.] 



Coffee. — Coffee grows well in several parts of the Philippine Islands, and 

 beans of excellent quality are produced, especially in the highlands of 

 Luzon. Scientific cultivation is probably necessary to increase the output. 



Cacao. — First-class cacao is grown to a limited extent in many local- 

 ities, and the production could be readily increased to export proportions. 



Papain. — Papaya gum of as great activity as the best on the market can 

 be and has been produced in the Philippines. 



Strychnine. — Strychnine can be extracted from the seeds of Strychnos 

 ignatii, a plant indigenous to the Philippines. 



Datura alba. — The leaves and the seeds of Datura alba, which grows wild 

 in the Philippines, are valuable as an asthma remedy and for other medic- ' 

 inal purposes. 



Starch. — Several species of Philippine plants yield a high percentage of 

 starch. The most promising of these are cassava, or camoteng cahoy
