The government of the Sooloo Archipelago is a kind of oligarchy, and the supreme authority is vested in the Sultan and the Ruma Bechara or trading council. This consists of about twenty chiefs, either datus, or their next in rank, called orangs, [65] who are governors of towns or detached provinces. The influence of the individual chiefs depends chiefly upon the number of their retainers or slaves, and the force they can bring into their service when they require it. These are purchased from the pirates, who bring them to Sooloo and its dependencies for sale. The slaves are employed in a variety of ways, as in trading prahus, in the pearl and biche de mar [66] fisheries, and in the search after the edible birds'-nests. A few are engaged in agriculture, and those who are at all educated are employed as clerks. These slaves are not denied the right of holding property, which they enjoy during their lives, but at their death it reverts to the master. Some of them are quite rich, and what may appear strange, the slaves of Sooloo are invariably better off than the untitled freemen, who are at all times the prey of the hereditary datus, even of those who hold no official stations. By all accounts these constitute a large proportion of the population, and it being treason for any low-born freeman to injure or maltreat a datu, the latter, who are of a haughty, overbearing, and tyrannical disposition, seldom keep themselves within bounds in their treatment of their inferiors. The consequence is, the lower class of freemen are obliged to put themselves under the protection of some particular datu, which guards them from the encroachment of others. The chief to whom they thus attach themselves, is induced to treat them well, in order to retain their services, and attach them to his person, that he may, in case of need, be enabled to defend himself from depredations, and the violence of his neighbours. Such is the absence of legal restraint, that all find it necessary to go abroad armed, and accompanied by a trusty set of followers, who are also armed. This is the case both by day and night, and according to the Datu's account, frequent affrays take place in the open streets, which not unfrequently end in bloodshed.
