The system of trade adopted by the Dutch, following in the footsteps of the Portuguese, was bad. Each in turn made of trade a monopoly, excluding the vessels of every other nation. Such produce of the country as was suitable for the Chinese market had to be sent first to one of their own depôts, thence to be transhipped to China, and all direct intercourse with China was checked. This cessation of direct trade affected the prosperity of the ports, among others Bruni, in a variety of ways. First, by the circuitous direction of the trade the exports became too expensive to fetch the cost of the double carriage, and in course of time dwindled to nothing. In the next place, the cessation of immediate intercourse with China arrested the flow of immigrants, hard-working and frugal men, who would have exploited the industries and natural products of the island. A third, and that the most serious effect of all, as a result of the extinction of honest trade and internal development, was the encouragement given to piracy. The sultans and rajahs were unable to maintain their state, and the people to satisfy their requirements by just means, and so commenced to live by piracy. So long as immediate requirements were satisfied by this means, they gave no thought to the morrow; it did not occur to them, or they were too ignorant to consider, that they were pulling up by the roots that on which the future prosperity of their countries depended. "The Dutch had no sooner established themselves at Batavia than, not satisfied with transferring to it the emporium of Bantam, they conceived the idea of making it the sole and only depôt of the commerce of the Archipelago.... The destruction of the native trade of the Archipelago by this withering policy may be considered as the origin of many of the evils and of all the piracies of which we now complain. A maritime and commercial people, suddenly deprived of all honest employment, or the means of respectable subsistence, either sunk into apathy and indolence, or expended their natural energies in piratical attempts to recover by force and plunder what they had been deprived of by policy and fraud." So wrote Sir Stamford Raffles in 1821.
