Having told them to bring all the articles they wanted to sell, I quickly bought some good masks and a number of tail feathers from the rhinoceros hornbill, which are regarded as very valuable, being worn by the warriors in their rattan caps. All were "in the market," prices were not at all exorbitant, and business progressed very briskly until nine o'clock, when I had made valuable additions, especially of masks, to my collections. The evening passed pleasantly and profitably to all concerned. I acquired a shield which, besides the conventionalised representation of a dog, exhibited a wild-looking picture of an antoh, a very common feature on Dayak shields. The first idea it suggests to civilised man is that its purpose is to terrify the enemy, but my informant laughed at this suggestion. It represents a good antoh who keeps the owner of the shield in vigorous health. The kapala's house had at once attracted attention on account of the unusually beautiful carvings that extended from each gable, and which on a later occasion I photographed. These were long boards carved in artistic semblance of the powerful antoh called nagah, a benevolent spirit, but also a vindictive one. The two carvings together portrayed the same monster, the one showing its head and body, the other its tail. Before being placed on the gables a sacrifice had been offered and the carvings had been smeared with blood--in other words, to express the thought of the Dayak, as this antoh is very fierce when aroused to ire, it had first been given blood to eat, in order that it should not be angry with the owner of the house, but disposed to protect him from his enemies. While malevolent spirits do not associate with good ones, some which usually are beneficent at times may do harm, and among these is one, the nagah, that dominates the imagination of many Dayak tribes. It appears to be about the size of a rusa, and in form is a combination of the body of that animal and a serpent, the horned head having a disproportionately large dog's mouth. Being an antoh, and the greatest of all, it is invisible under ordinary conditions, but lives in rivers and underground caves, and it eats human beings. Lidju, who accompanied me as interpreter and to be generally useful, had aroused the men early in the morning to cook their rice, so that we could start at seven o'clock, arriving in good time at the Kayan kampong, Long Blu. Here, on the north side of the river, was formerly a small military establishment, inhabited at present by a few Malay families, the only ones on the Mahakam River above the great kihams. Accompanied by Lidju I crossed the river to see the great kampong of the Kayans.
