At Tamaloe animals and birds were not plentiful, the call of the wah-wah usually imparting a little life to the mornings; and I once heard a crow. I do not remember to have seen on the whole Busang River the most familiar of all birds on the Bornean rivers, an ordinary sandpiper that flits before you on the beach. Birds singing in the morning are always rare except in the localities of paddi fields. The one most likely to attract attention on a forenoon is the giant hornbill, and as we advanced up the Busang its laugh might still be heard. Much more unusual was the call of some lonely argus pheasant or a crow. A few of the beautiful white raja birds were observed.

Wild pigs and deer continued plentiful, but the monkeys seemed gradually to disappear. Fish there were in plenty, but they were now of smaller kinds, not agreeable to eat, having an oily taste and mostly very bony. At all our camping places ants of various kinds were numerous, also inside of the tent, but they did not seem to be obnoxious. Just before sunset the loud voices of the cicadas began, and after dark lovely moths were attracted by my lamp, while during the night bats flew in and out of my tent. The humidity of the atmosphere was great. Safety matches would not strike fire unless kept in an airtight box. My cameras were inside of solid steel boxes, provided with rubber bands against the covers, making them water-tight. Nevertheless, upon opening one that had been closed for three weeks the camera inside was found to be white with mould.

It was rough and hard travelling on account of incessant low kihams to be passed, or banks of small stones over which the prahus had to be dragged. The Penyahbongs had not yet learned to be good boatmen, often nearly upsetting the prahu when getting in or out. Occasionally long quiet pools occurred, and the scenery here was grand and thrilling. Graceful trees of infinite variety bent over the water, bearing orchids of various colours, while creepers hung down everywhere, all reflected in a calm surface which seldom is disturbed by the splashing of fish. The orchids were more numerous than I had ever seen before. A delicate yellow one, growing in spikes, had a most unusual aromatic fragrance, as if coming from another world.

In the morning a curtain of fog lies over the landscape, but about nine o'clock it begins to lift, and creeping up over the tree-tops gradually dissolves in the sun-light, while between the trees that border the river the deep-blue sky appears, with beautiful small cumulus clouds suspended in the atmosphere. With the exception, perhaps, of a large blue kingfisher sitting in solitary state on a branch extending over the water, or a distant hornbill with its cheerful grandiose laugh, there are no evidences of animal life, nevertheless the exquisite scenery seems to lure the beholder on and on. To pass through this superb and silent realm was like a pleasant dream. There are no mosquitoes and consequently no malaria.

We were progressing through a country of which little is known accurately beyond its somewhat hilly character, and the fact that it is uninhabited except for small transient parties of Malays searching for rattan or rubber. The upper part of our route to the divide, a comparatively short distance, had not, to my knowledge, been traversed by white men before. Errors were corrected on the map of the watershed region.

One day at noon, while we were waiting for the largest prahu to overtake us, fresh tracks of pig were discovered on the bank, and the Saputan dog, a very wise animal, was landed. A few minutes later he began the peculiar barking which indicated that he had caught the scent, and one man seized a sumpitan and ran off into the utan as fast as his legs could carry him, holding the weapon in his right hand in a horizontal position, spear end first. It sounded as if the dog might be holding the pig in the water a little higher up, but this was soon found to be a mistake when the barking was heard close by. The Saputan kapala then jumped from my prahu, drew his parang, and with wonderful elastic movements disappeared in the utan. Two or three minutes later they returned, one man bearing in his arms a scarcely half-grown live pig, which had been hit by the sumpitan. The whole affair lasted barely ten minutes.

At another place, where we were again waiting for the big prahu, the Penyahbongs amused themselves with wrestling in water up to their shoulders. After some dancing around, the fight would invariably finish by both disappearing and after a few seconds coming to view again. This caused much merriment, especially to the wrestlers themselves, who laughed immoderately when reappearing.

We entered the tributary Bulau, and a couple of hours later arrived at its junction with Bakkaang, at the source of which we expected to cross the watershed. The river, which was rather narrow, would be difficult to ascend unless we had showers. Luckily rain fell during the night, and although delayed by trees that had fallen across the stream, which was from six to ten metres wide, we made a good day's work and camped at an attractive old clearing of rattan gatherers.

I spent the next forenoon in an excursion to a place within the jungle, where birds and animals sometimes congregate in great numbers to obtain the salt water which issues from the earth or rocks. This masin (salt water) was known to the Malay rattan seekers in our party, who had snared birds and deer there. In the dry season hundreds of birds of various kinds would gather. By wading up a small stream for twenty minutes we reached a place where water exuded from a rock, especially at its top, and by following the stream upward for another twenty minutes we arrived at the larger one, where the ooze from the rocks overflowed the ground. Only tracks were seen, but our guide said that after three rainless days in succession birds and animals would be sure to come there. Myriads of yellowish-gray flies covered the ground as well as the rocks, and after having taken some specimens of algae, also some white gelatinous stuff with which the Malays rub themselves when afflicted with beri-beri, I returned to camp.

In spite of frequent light showers the stream failed to rise appreciably, and our goods had to be carried on the back of the men to our next camping place. The following morning we started in a heavy rain at which we rejoiced, because it enabled us to use our prahus until we reached the foot of the dividing ridge. At noon we arrived in camp, with our clothing thoroughly wet. What the downpour might have left intact the Penyahbongs, forgetting everything but the safety of the prahus, had done their best to drench by splashing water all the time. Just as we had made camp the rain ceased and with it, being near the source of the stream, the overflow too passed away. In dry weather it would be a tedious trip to get up the Bakkaang.
