Of Anaman I know nothing; of Kabatuan I saw little beyond the Malay town; but I was informed that the Ida’an were numerous in the interior of this river, as well as on the hills that surround Mengkabong. I have placed them at two thousand, which is not a high estimate. Mengkabong contains also an extensive Baju population, and in estimating them at six thousand, it is, I believe, much below the number. The villages are numerous, and the chief town large. It is possible that there are not more than a thousand fighting-men, but the Bajus are holders of slaves, and there are also many strangers settled among them. Sulaman is placed at a thousand, which includes both Baju and Ida’an, and may be a little over the mark; for it I have nothing but vague native testimony. Abai contains about thirty houses, perhaps not above two hundred people; while on the hills are a few small villages of Ida’an. I have put them at one hundred and twenty-five fighting-men, or five hundred in all. Tampasuk contains about one hundred and fifty Lanun men, or seven hundred and fifty population. Bajus, five hundred, or two thousand five hundred people. I have multiplied the Lanun and Baju fighting-men by five, as they have many slaves both male and female. Gaya Bay contains about three hundred people. The population of these districts may therefore be entered as follows:-- Gaya Bay 300 Malays and others. Kabatuan 1,000 Ida’an. Mengkabong 6,000 Bajus and others. „ 1,000 Ida’an. Tawaran 10,000 Ida’an. Sulaman 1,000 Ida’an and Bajus. Abai 200 Bajus. „ 500 Ida’an. Tampasuk 2,500 Bajus. „ 750 Lanuns. „ 16,000 Ida’an. ------ Total 45,250 The only figures in the above which I think may possibly be overstated, are the Bajus of Tampasuk. We may fairly reckon the population of the districts between Gaya Bay and Tampasuk at forty-five thousand, being quite aware, at the same time, that it is founded on very loose data; but it may serve as a guide to future inquirers.
