These nineteen nomads had black hair, straight in some cases, wavy in others. Most of them had a semblance of mustache and some hair on the chin. Their bodies looked perfectly smooth, as they remove what little hair there may be. Some of them had high-arched noses. The thigh was large, but the calf of the leg usually was not well-developed, though a few had very fine ones; and they walked with feet turned outward, as all the Dayaks and Malays I have met invariably do. The only garment worn was a girdle of plaited rattan strings, to which at front and back was attached a piece of fibre cloth. Although dirty in appearance, only one man was afflicted with scaly skin disease. Visits to the hill-tops are avoided by them on account of the cold, which they felt much in our camp. Their dark-brown eyes had a kindly expression; in fact they are harmless and timid-looking beings, though in some parts of Borneo they engage in head-hunting, a practice probably learned from the Dayaks. Those I talked with said the custom was entirely discontinued, although formerly heads of other Punans, Malays, or Dayaks had been taken.

These natives, following no doubt an observance prevalent among the Dayaks, had some of their teeth filed off in the upper jaw, the four incisors, two cuspids, and two bicuspids. Our Kayans from Kaburau had no less than ten teeth filed off, the four incisors and three more on either side. The operation is performed when a boy or girl becomes full-grown. For the boys it is not a painful experience, but the girls have theirs filed much shorter, which causes pain and loss of blood.

The Punans make fire by iron and flint which are carried in a small bamboo box. They are expert regarding the manufacture of the sumpitan (blow-pipe), and are renowned for their skill in using this weapon and can make the poisonous darts as well as the bamboo caskets in which these are carried. Subsisting chiefly upon meat, their favourite food is wild pig.

At the birth of a child all the men leave the premises, including the husband. The dead are buried in the ground a metre deep, head toward the rising sun. The Punans climb trees in the same manner as the Kayans and other Dayaks I have seen, i.e., by tying their feet together and moving up one side of the tree in jumps. The Kayans in climbing do not always tie the feet.

These shy nomads remained in camp two days and allowed themselves to be photographed. One morning seven of them went out to look for game, armed with their long sumpitans and carrying on the right side, attached to the girdle, the bamboo casket that contained the darts. They formed a thrilling sight in the misty morning as in single file they swung with long, elastic steps up the hill. Though the Punans are famous as hunters and trappers, they returned in a few hours without any result. Next morning when I ventured to begin taking their measurements they became uneasy and one after another slipped away, even leaving behind part of their promised rewards, rice and clothing for the women, and taking with them only tobacco and a large tin of salt, which I rather regretted, as they had well earned it all.

We made a trip of a few days' duration to the next elevation, Gunong Rega, in a northerly direction, most of the time following a long, winding ridge on a well-defined Punan trail. The hill-top is nearly 800 metres above sea-level (2,622 feet), by boiling thermometer, and the many tree-ferns and small palm-trees add greatly to its charm and beauty.

Toward the end of February I made my way back to the river. From our last camp, one day's march downward, three of my strongest Kayans had carried 45 kilograms each. My Javanese cook, Wong Su, on arriving in camp, felt ill and I found him lying prostrate. He had not been perspiring on the march down the hills and complained of chilly sensations. He also presented the symptoms of a cold attack of malaria, but it was simply the effects produced by the bites of leeches, to which he was particularly susceptible. He had seven bites on one ankle and two on the other, and the resulting wounds were swollen and suppurating, but by the application of iodine followed by hot compress bandages, he was able to resume his work in three days. Nevertheless, suppuration formed even at a distance from the wounds, and five months later they were not entirely healed. It is bad policy to remove leeches forcibly in spite of the temptation to do so. The application of salt or tobacco juice makes them drop off, and the wounds are less severe, but few persons have the patience to wait after discovering a leech. The animal is not easily killed. The Dayaks always remove it with the sword edge and immediately cut it in two.

On our return to our old lodging-house near Kaburau I spent a week making ethnological collections from the Kayan, who brought me a surprising number, keeping me busy from early until late. Before continuing my journey up the river I decided to go down to Tandjong Selor in order to buy necessary provisions and safely dispose of my collections. The Kayans were glad to provide prahus, the keelless boats which are used by both Dayak and Malay. The prahu, even the largest size, is formed from a dugout, and to the edge on either side are lashed two boards, one above and overlapping the other. This is accomplished by threading rattan through numerous small holes. As these are not completely filled by the rattan, they are plugged with fibre and calked with damar to prevent leakage.

In order to travel more comfortably we lashed a prahu at either side of mine, while many of the natives who took advantage of the occasion to visit the shops in town, tied theirs at the rear of ours. It was a gay flotilla that proceeded down the river, the Dayaks singing most of the time, especially the women who accompanied their husbands, a number of them sitting in my large but crowded prahu. The women never seemed to grow tired of the Mae Lu Long, a jolly song which I had several times heard them singing when returning from the fields in the evening. Its words are of a language called Bungkok. The Kenyahs have the same song, and when I sang it to the Penihings on the Upper Mahakam they also understood it. These Kayans (Segai) are able to sing in the following six dialects or languages: Bungkok, Tekená, Siudalong, Siupanvei, Lepói, and Lui Lui.
