Many insects were about at night. Longicornes scratched underneath my bed, and moths hovered about my American hurricane lamp hanging outside the tent-door. Leeches also entered the tent and seemed to have a predilection for the tin cans in which my provisions and other things were stored. In the dim lamplight I could sometimes see the uncanny shadows of their bodies on the canvas, raised and stretched to an incredible height, moving their upper parts quickly to all sides before proceeding on their "forward march." To some people, myself included, their bite is poisonous, and on the lower part of the legs produces wounds that may take weeks to cure.
One day native honey was brought in, which had been found in a hollow tree. It was sweet, but thin, and had no pronounced flavour. A few minutes after the honey had been left on a plate in my tent there arrived a number of large yellow hornets, quite harmless apparently, but persevering in their eagerness to feast upon the honey. During the foggy afternoon they gathered in increased numbers and were driven off with difficulty. The temporary removal of the plate failed to diminish their persistence until finally, at dusk, they disappeared, only to return again in the morning, bringing others much larger in size and more vicious in aspect, and the remaining sweet was consumed with incredible rapidity; in less than two hours a considerable quantity of the honey in the comb as well as liquid was finished by no great number of hornets.
Later several species of ants found their way into my provision boxes. A large one, dark-gray, almost black, in colour, more than a centimetre long, was very fond of sweet things. According to the Malays, if irritated it is able to sting painfully, but in spite of its formidable appearance it is timid and easily turned away, so for a long time I put up with its activities, though gradually these ants got to be a nuisance by walking into my cup, which they sometimes filled, or into my drinking-water. Another species, much smaller, which also was fond of sugar, pretended to be dead when discovered. One day at ten o'clock in the morning, I observed two of the big ants, which I had come to look upon as peaceful, in violent combat outside my tent. A large number of very tiny ones were busily attaching themselves to legs and antennae of both fighters, who did not, however, greatly mind the small fellows, which were repeatedly shaken off as the pair moved along in deadly grip.
One of the combatants clasped his nippers firmly around one leg of the other, which for several hours struggled in vain to get free. A small ant was hanging on to one of the victor's antennae, but disappeared after a couple of hours. Under a magnifying-glass I could see that each fighter had lost a leg. I placed the end of a stick against the legs of the one that was kept in this merciless vice, and he immediately attached himself to it. As I lifted the stick up he held on by one leg, supporting in this way both his own weight and that of his antagonist. Finally, they ceased to move about, but did not separate in spite of two heavy showers in the afternoon, and at four o'clock they were still maintaining their relative positions; but next morning they and the other ants had disappeared.
CHAPTER V
MEETING PUNANS, THE SHY JUNGLE PEOPLE—DOWN THE RIVER AGAIN—MY ENTHUSIASTIC BOATMEN-MALAYS VERSUS DAYAKS
At my request the raja, with a few companions, went out in search of some of the shy jungle people called Punans. Seven days afterward he actually returned with twelve men, who were followed by seven more the next day. All the women had been left one day's journey from here. These Punans had been encountered at some distance from kampong Bruen, higher up the river, and, according to reports, made up the entire nomadic population of the lower Kayan River. Most of them were rather tall, well-made men, but, as a result of spending all their lives in the darkness of the jungle, [*] their skin colour, a pale yellowish brown, was strikingly lighter, especially the face, than that of the Kayans.
[Footnote *: In von Luschan's table, Punan 15, Kayan 22.]
They actually seemed to hate the sun, and next day when it broke through the mist for a little while they all sought shelter in the shade of trees. As a result of their avoidance of direct rays from the sun they have a washed-out, almost sickly pale appearance, contrasting strangely with the warm tone of light brown which at times may be observed among the Dayaks. This is probably the reason why they are not very strong, though apparently muscular, and are not able to carry heavy burdens. They began at once to put up a shed similar to those of the Dayaks, but usually their shelters for the night are of the rudest fashion, and as they have only the scantiest of clothing they then cover themselves with mats made from the leaves of the fan-palm.
On the Upper Mahakam I later made acquaintance with some of the Punans who roam the mountainous regions surrounding the headwaters of that river. Those are known under the name Punan Kohi, from a river of that name in the mountains toward Sarawak. The members of the same tribe further east in the mountains of the Bulungan district are called Punan Lun, from the River Lun, to whom the present individuals probably belonged. According to the raja, there are two kinds of Punans here, and his statement seems to be borne out by the variations in their physical appearance.
