There is little to notice, except that the banks are generally flat, fringed with a low jungle, at the back of which the Muruts formerly farmed. A stranger passing up the river would be apt to infer that no population had tenanted this district for a century, as there are no signs of cultivation, but the natives generally prefer farming in spots not exposed to floods or intrusion. I have been out deer-snaring in this neighbourhood, which made me notice that at the back of the belt of jungle which lines the river banks there are signs of a former extensive rice-planting. Sagan on the right bank is a fine hill, perhaps 1,500 feet in height; between it and Suñgei Damit is the low range of Rudi, running along the edge of one of the reaches, and terminating a little below the Damit. This tributary is now very low, there having been but little rain to the S. E., so that I hope the discoloured water of the Limbang comes from the Madalam branch. The water, however, is much higher than it was when we ascended the river last February, as the Batang rapids are concealed; these rapids are caused by a collection of logs, mixed with sand and mud, and extend for several hundred yards. I noticed the rocks occasionally cropping out of the banks. At the mouth of the Damit I took the dip and strike: dip N. E. by N., angle 31·5; strike S. E. by E. There is a high peak to the southward (S. by E.) which is apparently the end of the Molu range; it bends, the natives say, towards the Limbang: if not, it is a separate range, but the same that I see from the back of the Consulate at Brunei. I think that the thousands of pigs which inhabit this jungle contribute to the discoloration of the water: every night they descend to the banks and rout up the soft mud into heaps, which are easily washed away by rain or the rise of the river. The fish we have caught are all small, though there are fine ones in the centre of the stream where the net cannot be used: we see them occasionally rise to the surface, causing a great commotion. Japer tells me that the people of Adang occasionally obtain their salt from traders of the east coast, but their usual supply is derived from salt springs, and this is confirmed by Orang Kaya Upit. Japer adds that, when head-hunting round the great mountain of Tilong, in the centre of Borneo, he saw a salt spring that burst from the ground in a volume of about fifteen inches in diameter, rising three feet, and then spreading in a shower around: this is the source, he says, of the Bangermasin, and the reason of its being so called (_masin_, briny). He thinks there must be a passage all the way from the sea to cause this salt spring, and no reasoning will convince him to the contrary: his companions confirm _his_ belief by _their_ implicit belief. There is also a large lake at the foot of Tilong; he saw it, but did not go near it, as it might be the residence of spirits.
