White and sweet potatoes, yams, sweet and bitter yuccas, sago and okra, may also be mentioned.
Gambier, cotton and sago are cultivated with success.
Rice, maize, cocoa-nuts, sugar-cane and a variety of fruits are grown; and some tobacco is exported to Europe; but by far the most important production is the sago palm, which grows abundantly in the swampy districts, especially of Eastern Ceram, and furnishes a vast supply of food, not only to Ceram itself, but to other islands to the east.
Palm-trees are abundant in great variety, including the nipah, which is much used for thatching, the cabbage, fan, sugar, coco and sago palms. The last two furnish large supplies of food to the natives, some copra is exported, and sago factories, mostly in the hands of Chinese, prepare sago for the Dutch and British markets.
For sodii arsenas and cacodylate see Arsenic. Sapo durus (hard soap) is a compound of sodium with olive oil, and sago animalis (curd soap) is chiefly sodium stearate.
The principal cultivated plants, apart from sugar-cane and coffee, are rice (in great variety of kinds), the coco-nut palm, the areng palm, the areca and the sago palms, maize, yams, and sweet potatoes; and among the fruit trees are the Indian tamarind, pomegranate, guava, papaw, orange and lemon.
