In April, 1872, the Rajah, accompanied by a staff of English and Malay officers, visited Bruni in the Government steamers _Heartsease_ and _Royalist_. It was perhaps not unnatural that this visit was at first regarded with suspicion as being in the form of a demonstration against Bruni, to back unheeded protests against the maltreatment of Sarawak subjects, and the nonfulfilment of treaty engagements. But this impression was soon dispelled, and the Rajah was received by the Sultan, "a fat, kindly-faced old man of some eighty years of age," with cordiality and honour. The Rajah's main object in visiting Bruni was to obtain an effective guarantee that his subjects trading in Bruni territory should not be molested and unwarrantably interfered with. A treaty conceding all that the Rajah asked for was accordingly drawn up and ratified by the Sultan, and was satisfactory enough on paper. The Sultan solemnly undertook the redressing of injuries, guaranteed protection to traders, and the imposition of fair and moderate customs duties only. But this treaty, owing to the Sultan being powerless to enforce its provisions outside the capital, soon became worse than useless; for, relying on it being observed, Sarawak traders again ventured into the Bruni ports, only to meet with the same treatment as before. The extortion of outrageous customs dues went on as formerly. The Bruni nobles, "the most useless race that ever encumbered the earth,"[309] set themselves deliberately to frustrate every object aimed at in the treaty, and, so that they might keep the trade with its enormous profits to themselves, they plundered, and even killed those who ventured to compete with them. But their day was not to last for ever. The Kayans, driven to exasperation by the heavy fines and other extortions imposed upon them, eventually rose against these tyrants, and drove them out. [Illustration: THE SULTAN'S PALACE.] Next to the Rejang, the Baram is the largest river that flows into the sea on that coast. In its basin are congregated large populations of Kayans and Kenyahs. In 1872, the Rajah, accompanied by the Ranee, visited this river to ascertain for himself how far it would be safe for Sarawak subjects to trade there. He steamed a long way up the river, and was everywhere well received by the natives, who had been much depressed by extortion and were eager to be relieved from the thraldom in which they were held by Bruni. There had been no encouragement given to them to work the jungle produce in which their country was rich, except to purchase necessaries, and these could be obtained through their Bruni masters alone, and that at exorbitant prices. There was in consequence little trade at the time. But what this river is capable of producing may be shown by its trade returns at present. The exports, entirely of jungle produce, after the district had been for twenty years under Sarawak, amounted in 1906 to $272,223.
