Tea and camphor are the staple exports.
In 1755 Menghini published an elaborate study of the action of camphor on a great variety of different kinds of animals.
The motion of small pieces of camphor floating on water arises from the gradual solution of the camphor.
If the hoop enclose an area of (say) one-third of the maximum, and if the water be clean, camphor fragments floating on the interior enter with vigorous movements.
Gutta-percha (getah percha in the vernacular), camphor, cinnamon, cloves, nutmegs, gambir and betel, or areca-nuts, are all produced in the island; most of the tropical fruits flourish, including the much-admired but, to the uninitiated, most evil-smelling durian, a large fruit with an exceedingly strong outer covering composed of stout pyramidal spikes, which grows upon the branches of a tall tree and occasionally in falling inflicts considerable injuries upon passers-by.
