Add a third 1,220 families not paying revenue. ----- Total 4,880 families. At six to a family, this would give nearly 30,000 people. Comparing this statement with those given by the assembled chiefs, I find they slightly differ. They reckoned the population at 36,000 people; and I account for it, first, by Sherif Hasan not having given the population of Bintasan; and, secondly, by his only mentioning the number of families on the Buñgun who paid tribute to his father, there being above a thousand families who did not. They all represented the district of Bengkoka, not included in the above list, as the most important and populous of all; it is on the eastern coast of the bay, and the river, though barred at the entrance, is reputed deep inside. Its population is stated at 16,000 Ida’an. The Malays and Sulus residing in all these districts are represented as not very numerous; in fact, as under 5,000, of whom 1,500 are at Panchur, 1,500 at Bengkoka, and the rest scattered at the various other villages. If the above figures represent the numbers, there are about 52,000 Ida’an on the banks of the rivers flowing into the bay, and about 5,000 strangers. They all, however, explained that, when they enumerated the Ida’an, they only spoke of those villages which were under the influence of the people of the coast, and that there were many tribes among the mountains with whom they had little intercourse. I once met a party of these Ida’an; they were a dark, sharp-featured race, intelligent-looking, and appeared in features very much like the Land Dayaks of Sarawak. They were dressed in their war costume, consisting of heavy, padded jackets, but wore the chawat or cloth round their loins. They were slight and short men. The productions of these districts consist of rattans, wax, camphor, tortoise-shell, tripang or sea-slug, and kaya laka, a sweet-scented wood. Large quantities of rice and tobacco are grown, and, if encouraged, these cultivations would greatly increase. The only minerals as yet discovered are coal in the Bengkoka River, and tin in some stream at the foot of the Kina Balu range. I saw specimens of the latter, but no one has ventured to work it yet. The insecurity would prevent the Chinese succeeding.
