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.

The Sea-Dayaks have many good qualities that are more or less lacking in the other inland tribes. They are industrious, honest and thrifty, sober and cheerful, and comparatively moral. But the characteristics that mainly distinguish them are energy and independence. They are exceedingly sensitive, especially the women, and will seek refuge from shame in suicide;[[30]] like the Malays the men will sometimes, though not often, amok when suffering from depression caused by grief, shame, or jealousy, for in the East this peculiar form of insanity is by no means confined to the Malay as is popularly supposed.[[31]] Amongst them general social equality exists, and it is extended to their women. They do not suffer their chiefs to abuse their powers as the Kayan and Kenyah chiefs are allowed to do, but they are quite ready to submit to them when justness and uprightness is shown. They are superstitious and restless, and require a firm hand over them, and, "being like truant children, take a great advantage of kindness and forbearance, and become more rebellious if threats are not carried into execution." This was the advice given by the present Rajah to the Netherland officials some years ago. Their inherited desire for human skulls, and their old savage methods of obtaining them, still, in a degree, have a strong hold on the Sea-Dayak character, but against this it can be said to their credit that they are free from cruelty, and never torture a captive as do the Kayans and other tribes. They are kindly to their captives, and treat them as members of the family; and they were a peaceable people before they were led astray by the half-bred Arabs and the Malays.

The Sea-Dayaks are the collectors of jungle produce, in search of which they go on expeditions far into the interior—to Sumatra, the Malayan States, and North Borneo—and are away for months at a time.

The Dayak custom of head-hunting is founded on the same principle as that of scalp-hunting among the North-American Indians. A young man formerly found it difficult to obtain a wife till he had got at least one head to present to the object of his heart as token of his prowess; but it was quite immaterial whether the head was that of man or woman, of old or young. If a Dayak had lost a near relative it became his duty to obtain a head, for until this was accomplished, and a head feast had been given, the family must remain in mourning, and the departed relative would have no attendant in Sembayan (the shades); and so in the event of a chief dying it was incumbent upon the warriors of the tribe to procure one or more heads, in order that his spirit should be properly attended by the spirits of those sacrificed in his honour. Thus head-hunting became more or less a natural instinct, and an obligatory duty.

The ancient Chinese jars,[[32]] held in great esteem among the natives, and very highly prized, being supposed to be possessed of supernatural powers and healing virtues,[[33]] are of various kinds and value. The Gusi is the most valued, and is treated with great care and veneration, and stands about eighteen inches high. Then comes the Lingka, then the Benaga,[[34]] about two feet high, ornamented with the Chinese dragon. The Rusa[[35]] is the least valued. From a note made in 1890 these are the lowest prices they fetch—Gusi tuak, $1000; Gusi bulan, $700; Gusi chendanum, $500; Galagiau, $400; Lingka, $310; Rusa, $150, In 1890 $7 = £1. These jars are all brown in colour. The Dayaks and Kayans possess a few fine blue and white, and pink and white, old Chinese jars, some over five feet in height.

About forty years ago an enterprising Chinese petty dealer took samples of the jars to China and had clever imitations made. He realised a large sum by the sale, and started as a merchant on a large scale, grew rich, waxed fat, and became the leading and wealthiest Chinese merchant in Kuching. The Malays are clever in "faking" jars, especially such as are cracked, but the Dayaks are not now to be deceived by them.
