All the tribes visited by me suffer more or less from various kinds of skin diseases caused by micro-parasitic animals, the Kenyahs and Oma-Sulings in a much less degree. The most repulsive form, just described, does not seem to interfere with general health. Three of my Kayan carriers thus affected were more muscular and stronger than the rest. One of them was the humorous member of the party, always cutting capers and dancing. Women are less affected than men, and I often saw men with the disfiguring scaly disease whose wives were evidently perfectly free from it. A party of six fine-looking Penyahbongs were here on a rhinoceros hunting expedition. They came from the western division, and as the rhino had been nearly exterminated in the mountain ranges west and northwest of Tamaloë, the hunters were going farther east. Such a party carries no provisions, eating sago and animals that they kill. Their weapons are sumpitans and parangs, and equipment for stamping sago forms part of their outfit. The rhino is approached stealthily and the large spear-point on one end of the sumpitan is thrust into its belly. Thus wounded it is quite possible, in the dense jungle, to keep in touch with it, and, according to trustworthy reports, one man alone is able in this way to kill a rhino. It is hunted for the horn, which Chinamen will buy. At my request two of the hunters gave war-dances very well, taking turns. Their movements were graceful, and in the moonlight they appeared sinuous as serpents. The same dance obtains in all the tribes visited, and the movement is forward and back, or in a circle. It was performed by one man who in a preliminary way exercised the flexible muscles of the whole body, after which he drew his sword, seized the shield which was lying on the ground and continued his dancing more vigorously, but with equal grace. Pisha, the chief, came to the dance, and the meeting with the new arrivals, though silent and undemonstrative, was decidedly affectionate, especially with one of them who was a near relative. Half embracing each other, they stood thus at least a minute. The Penyahbongs have rather long legs, take long paces, putting down their heels first. They have great endurance and can walk in one day as far as a Malay can in three. In the mountains the cold weather prevented them from sleeping much. It often happened that they were without food for three days, when they would drink water and smoke tobacco. Trees are climbed in the jumping way described before, and without any mechanical aid. Formerly bathing was not customary. Excrements are left on the ground and not in the water. They don't like the colour red, but prefer black. Fire was made by flint and iron, which they procured from the Saputans.
