On our arrival at Puruk Tjahu the low water at first made it doubtful whether the Otto would be able to proceed further, but during the night it rose five metres, continued rising, and changed into a swollen river, as in springtime, carrying sticks and logs on its dirty reddish waters. After a foggy morning the sun came out and we had an enchanting day's journey, the movement of the ship producing a soft breeze of balmy air after the rainy night and morning. We passed a timber float stranded on high ground, with Malay men, women, and children who had been living there for weeks, waiting for the water to rise again as high as where it had left them. They evidently enjoyed the unusual sight of the steamer, and followed us attentively.
In the afternoon we arrived at Poru, a small, oppressively warm kampong, deserted but for an old man and one family, the others having gone to gather rattan in the utan. This was to be our starting-point, where our baggage would have to be put in convenient shape for travel in boat and overland, and where we hoped it might be possible to buy prahus and obtain men by searching the kampongs higher up the river. In this we were disappointed, so the lieutenant went back to Puruk Tjahu, in the neighbourhood of which are many kampongs, nearly all Malay, there as well as here. He took with him one soldier who had proved to have an obnoxious disease, leaving us with five for the expedition, which we deemed sufficient.
On Christmas day I bought from an old Dayak a large, ripe fruit called in Malay nangca (artocarpus integrifolia) of the jack fruit family. It is very common. Before maturing it is used as an every-day vegetable, which is boiled before eating. I was surprised to find that when fully ripe this fruit has an agreeable flavour of banana, but its contents being sticky it is difficult to eat. The sergeant, with the culinary ability of the Javanese, prepared for the holiday a kind of stew, called sambil goreng, which is made on the same principle as the Mexican variety, but decidedly superior. Besides the meat or fish, or whatever is used as the foundation, it contains eight ingredients and condiments, all indigenous except red pepper and onions.
In the ladangs is cultivated the maize plant, which just then was in condition to provide us with the coveted green corn, and carried my thoughts to America, whence the plant came. Maize is raised on a very limited scale, and, strange to say, higher up the river the season was already over. At Poru we tried in vain to secure a kind of gibbon that we heard almost daily on the other side of the river, emitting a loud cry but different from that of the ordinary wah-wah. Rajimin described it as being white about the head and having a pronounced kind of topknot.
As far as we had advanced up the Barito River, Malay influence was found to be supreme. The majority of the kampongs are peopled by Malays, Dayaks at times living in a separate section. This relation may continue at the lower courses of the tributaries, yielding to a Dayak population at the upper portions. In the kampongs, from our present camp, Poru, up to the Busang tributary, the population continues to be subject to strong Malay influence, the native tribes gradually relinquishing their customs, beliefs, and vernacular. But back from the river on either side the Dayak still easily holds his own.
The old kapala of Poru had an attractive eight-year-old granddaughter, of a singularly active and enterprising disposition, who always accompanied him. He called my attention to the fact that she wore a solid-looking gold bracelet around each wrist, a product of the country. In the dry season when the river is low two or three hundred Dayaks and Malays gather here to wash gold, coming even as far as from Muara Tewe. The gold mixed with silver is made into bracelets, wristlets, or breastplates by these natives.
The lieutenant had been unable to secure more than sixteen men, all Malays, which was insufficient for the six prahus we had bought. Therefore it became necessary to travel in relays, the lieutenant waiting in Poru until our men and prahus should return from Telok Djulo, for which kampong the rest of us started in late December.
After considerable rain the river was high but navigable, and two days' travel brought us to a rather attractive kampong situated on a ridge. Rajimin accompanied by Longko, the principal one of our Malays, went out in the evening to hunt deer, employing the approved Bornean method. With a lamp in the bow the prahu is paddled noiselessly along the river near the bank. Rusa, as a large species of deer are called, come to the water, and instead of being frightened are attracted by the light. Rajimin, who was of an emotional and nervous temperament, missed two plandoks and one rusa, Longko reported, and when he actually killed a rusa he became so excited that he upset the prahu.
We started before seven o'clock on a glorious morning, January first. On the river bank some trees, which did not appear to me to be indigenous, were covered with lovely flowers resembling hibiscus, some scarlet, some yellow. I had my men gather a small bunch, which for several hours proved attractive in the prosaic Malay prahu. The equatorial regions have not the abundance of beautiful flowers that is credited to them by popular belief. The graceful pitcher-plants (nepenthes) are wonderful and so are many other extraordinary plant creations here, but they cannot be classed as beautiful flowers in the common acceptation of the word. There are superb flowers in Borneo, among them the finest in existence, orchids, begonias, etc., but on account of the character of their habitats, within a dense jungle, it is generally difficult to see them. The vast majority of orchids are small and inconspicuous, and in hunting for magnificent ones the best plan is to take natives along who will climb or cut down the trees on which they grow.
On the third day the river had become narrow and shallower, and early in the afternoon we arrived at Telok Djulo, a kampong of Ot-Danums interspersed with Malays. It is composed of many houses, forming one side of an irregular street, all surrounded with a low fence for the purpose of keeping pigs out. The storehouses recalled those of the Bulungan, with their wide wooden rings around the tops of the supporting pillars, to prevent mice from ascending. Outside of the fence near the jungle two water-buffaloes were always to be seen in the forenoon lying in a mud-pool; these we were warned against as being dangerous. These Dayaks, who are shy but very friendly, are said to have immigrated here over thirty years ago. They are mostly of medium size, the women stocky, with thick ankles, though otherwise their figures are quite good. The Ot-Danum men, like the Murungs, Siangs, and Katingans, place conspicuously on the calf of the leg a large tatu mark representing the full moon. When preparing to be photographed, men, women, and children decorate their chests with crudely made gold plates shaped nearly like a half moon and hanging one above another, generally five in number. One of the blians was a Malay.
