The report concedes it was the generally received opinion that the population was nearer 200,000, and if we include the Kayans, Kenyahs, etc., and accept the approximate correctness of the above figures, that estimate would be about correct. In 1871, the State extended as far as Kedurong Point only, but since that the territorial area has been nearly doubled. The population is now estimated at 500,000, though this is probably too liberal a calculation, and the following is a fairer estimate:— Coast population, Malays and Melanaus 100,000 Interior population, Land and Sea-Dayaks, Kayans and 250,000 Kenyahs Interior population other than these 18,000 Chinese population 45,000 Indians, Javanese, Bugis, etc 3,000 ——————— 416,000 The names by which the various tribes are known are those given to them by others, mostly by the coast people, or are taken from the name of the river on which they reside, or from which they came. _Daya_ (as it should be spelt, and as it is pronounced) in the Melanau and Bruni Malay dialect means "land," "in-land." So we have _Orang daya_, an inlander. _Ka-daya-an_ is contracted into _Kayan_; _Ukit_ and _Bukitan_ are from the Malay word _bukit_—a hill; and _tanjong_ is the Malay for a cape or a point round which a river sweeps. Hence _Orang Ukit_ or _Bukitan_, a hill-man,[40] and _Orang Tanjong_, riverside people. As in ancient Germany the districts were known by the names of the rivers that watered them, and each was a _gau_, so it is in Borneo, where the rivers are the roads of communication, and give their names to the districts and to the people that inhabit them. Indeed, in Borneo one can see precisely at this day what was the ancient _Gau-verfassung_ in the German Empire. The area of Sarawak is about 50,000 square miles, and the coast line about 500 miles.
