The Malays and Arabs being Muhammadans, looked down on the pagan Land-Dayaks, subject to their domination, as mere bondsmen, to be slaughtered, fleeced, or enslaved—to be treated, in a word, as their caprice dictated, without being taken to task for their misdeeds. The limit of their exactions was fixed by necessity. The point beyond which oppression ceased was that where nothing was left to be extorted. But over the Sea-Dayaks of Sekrang, Saribas, and Kanowit they had no power. These tribes were far too independent in character and powerful to submit to oppression. These Sea-Dayaks would follow their so-called masters on a piratical expedition, and would obey them only so far as it pleased themselves to do so. As to the Kayans, they were too greatly feared to be molested. The late Mr. H. B. Low[72] in 1879 was refused permission by the Sultan to cross into the Baram by the Limbang, for fear lest this should show the Kayans a way into Bruni. The Malay rulers oppressed their own people and the Melanaus almost as badly as they did the Land-Dayaks, murdering, robbing, and enslaving them. The Land-Dayaks in Sarawak were governed by local Malay datus called Patinggi, Bandar, and Temanggong. These officers monopolised the trade. When the Dayaks had collected rice, edible birds' nests, wax, etc., the Patinggi claimed the right to buy the produce at a price fixed by himself, and one that barely allowed the seller enough to pay for his own necessaries. And not only did the Patinggi claim the right of pre-emption, but so did all his relatives, and in the end so did every Bornean Malay of any position. If the poor Dayak did not produce sufficient to satisfy the Patinggi, girls and children were taken to make up the deficit and sold into slavery.[73] He would sometimes send a bar of iron to a headman of a tribe, whether the latter wanted it or not, and require him to purchase it at an exorbitant price fixed by the sender. The man dared not refuse; then another bar was sent, and again another, till the Dayak chief was reduced to poverty. If a Malay met a Dayak in his boat, and the boat pleased him, he would cut a notch in the gunwale in token that he appropriated it to his own use. Possibly enough some other Bornean Malay might fancy the same boat and cut another notch. This might occur several times. Then the Dayak was required to hand over his boat to the first who had marked it, and to indemnify the other claimants to the value of the vessel.
