(The Pengulu Dalam, Munan)] A Sea-Dayak is a clean built man, upright in gait, not tall, the average height being 5 ft. 3 inches. The nose is somewhat flat, the hair straight with no curl in it. The face is generally pleasing from the frankness and good nature that show in it. The women have good figures, light and elastic; well-formed busts, with interesting, indeed often pretty, faces; the skins are, as already stated, of so light a brown as to be almost yellow. They have lustrous dark eyes and black, straight hair. The Dayaks are very fond of their parents, brothers, sisters, and of their children, and often a strong attachment exists between man and wife that lasts for life. The Dayaks have each but one wife, but it does not follow by any means that the first union lasts. A young couple may find incompatibility of temper after a week or two, and the union is dissolved on the plea of a dream inimical to its continuance. Incest is considered to be the worst of crimes, bringing a curse on the country. Both incest and bigamy were formerly punishable by a cruel death, now by heavy fines, but for the former offence the fine is far heavier than for the latter. The Sea-Dayaks are most hospitable, indeed a breach of hospitality is regarded as a punishable offence. They obtained their designation from the English who first came in contact with them, on account of their skill in navigating the sea along the coast, although living inland, and to differentiate them from the Dayaks of Sarawak proper, who were styled Land-Dayaks, because these latter were inexpert boatmen, and very few of them could paddle or swim. As shown farther on, Dayak really signifies an _inland man_. The Sea-Dayak is now the dominant race in Sarawak, and in time will become so over the whole of the north-west of Borneo. The spread of this stock in former years appears to have been slow, owing to continual intestine wars, but since the advent of the white man, the discontinuance of these feuds, and the forced adoption of a peaceable life, these people have increased enormously in numbers. Fifty years ago there were but few of them to be found outside the Batang Lupar, Saribas, and Kalaka river-basins, but now, though the population on these rivers has grown considerably, it is less than that of the same race on the Rejang alone, and they are spreading into the Oya, Muka, Tatau, and Baram river-basins. The Melanau population of the two first-named rivers live entirely either on the coast or near to it, and the Dayaks found the upper reaches unoccupied.
