As an instance of this we have the Lugats, of whom only a very few are left, the Lisums, the Bliuns, a tribe that has quite died out, the Segalangs, and the Seru Dayaks of the Kalaka, a tribe which is fast disappearing. The above sub-tribes take their name from rivers widely apart, and though their names differ they are of the same race, sub-tribes of the Ukits. Their tradition is that three or four hundred years ago the Ukits lived in the Lugat (now the Gat) river, a branch of the Baleh (hence we have the Lugats now living in the Anap), but they were driven out by the Kayans. Some went to the Lisum river (hence we have the Lisums), and some to Kapit, where they built strong houses on the site of the present fort, but these they were eventually forced to evacuate, and again they migrated down river, first to Tujong, near the Kanowit, and afterwards farther down again to Bunut, by Benatang. From Bunut they were driven out by their implacable foes, and they dispersed to Segalang (in the Rejang delta), to Bliun (in the Kanowit), and to Seru in the Kalaka.[19] This tradition is supported by the strong evidence of language, and there is little reason for disregarding it. After being driven out of Lugat, some of the Ukits went over to the Kapuas, where, as in the Baleh, to which river some eventually returned, they are still known as Ukits. The Bliuns, Segalangs, and Serus became civilised owing to contact with the Malays and Melanaus. The Ukits, Bukitans, and Punans, with the exception of the Punan Bah of Balui, are the wildest of all the races in the island. The Ukits are light in complexion; tall and well knit, and better looking than other inland tribes. Formerly they did not reside in houses, or cultivate the soil, but roamed about in the jungle, and subsisted on wild fruit and the animals they killed. But some of these have begun to erect poor dwellings, and do a little elementary farming. They are expert with the blow-pipe, and in the manufacture of the upas-poison, with which the points of their needle-like arrows are tinged. But it is quite open to question whether these poor savages may not be a degenerate race, driven from their homes and from comparative civilisation by more powerful races that followed and hunted them from their farms to the jungle. Beccari (_op. cit._ p. 363) says that they "are savages in the true name of the word, but they are neither degraded nor inferior races in the series of mankind. Their primitive condition depends more than anything else on their nomadic or wandering life, and on the ease with which they live on the produce of the forests, and on that of the chase which the sumpitan (blow-pipe) procures for them. This has no doubt contributed to keep them from associating with their fellow-beings, and from settling in villages or erecting permanent houses. I believe that these, although they must be considered as the remnants of an ancient Bornean people,
