There is no published Code of Laws, but the Raja, when the occasion arises, issues regulations and proclamations for the guidance of officials, who, in criminal cases, follow as much as possible the Indian Criminal Code. Much is left to the common sense of the Judicial Officers, native customs and religious prejudices receive due consideration, and there is a right of appeal to the Raja. Slavery was in full force when Sir JAMES BROOKE assumed the Government, all captives in the numerous tribal wars and piratical expeditions being kept or sold as slaves. Means were taken to mitigate as much as possible the condition of the slaves, not, as a rule, a very hard one in these countries, and to gradually abolish the system altogether, which latter object was to be accomplished by 1888. The principal item of revenue is the annual sum paid by the person who secures from the Government the sole right of importing, preparing for consumption, and retailing opium throughout the State. The holder of this monopoly is known as the "Opium Farmer" and the monopoly is termed the "Opium Farm." These expressions have occasionally given rise to the notion that the opium-producing poppy is cultivated locally under Government supervision, and I have seen it included among the list of Borneo products in a recent geographical work. It is evident that the system of farming out this monopoly has a tendency to limit the consumption of the drug, as, owing to the heavy rental paid to the Government, the retail price of the article to the consumer is very much enhanced. Were the monopoly abolished, it would be impossible for the Government efficiently to check the contraband importation of so easily smuggled an article as prepared opium, or _chandu_, and by lowering the price the consumption would be increased.
