Between us and the mountains, bearing S.E. by E. eighteen miles, there was a grassy plain, perhaps three miles by two, on which were many villages, and through this there flowed a fair-sized river. We could trace its course as far as the third spur that springs from the main one; then a line of hills appeared to obstruct it; but beyond we could again trace the course of a stream, which is probably its source. This river, it was stated by the people of the country, flows into the lake of Kina Balu. It runs from the S.W. to the N.E. With the exception of the plain above-mentioned and a marsh, whose commencement we could observe north-east of the plain, all the country appeared hilly, and most of the land was cleared, and either under cultivation, or showed the remains of former plantations. We could observe in the second valley two villages--the first called Tuhan, the next Inserban, and at both cotton is said to be cultivated. Many villages and detached houses were also observed, whose names our guides had forgotten. The road to the lake is by the two above-mentioned villages, while the names of those beyond are Penusuk, Tambian, Paka, and Koporiñgan--these are stated to be on the route, or close to the lake. A few words concerning this mythic sheet of water, as it has generally been considered: that it exists to the east of the mountain appears from inquiry to be almost certain. Its size it is unnecessary to estimate, though our informants stated that, standing on one bank, it was not possible to see the opposite one. It cannot, however, be of the great size marked in the old maps, or in the situation assigned to it, as the whole country, from E.S.E. to the western coast, was distinctly visible, and the Ida’an expressly stated that it was farther to the north and east of the plain I have before noticed. Mr. Low made many inquiries during our first trip, and we jointly questioned the Ida’an, on many occasions during our long stay at the Kiau village, and they spoke of it as a certainty, many affirming that they themselves had been on trading expeditions to it. I may add that Mr. De Crespigny, who lived some time at Maludu Bay, heard that the lake was to the south of Kina Balu, where it certainly is not. Peterman’s map is entirely incorrect as to the position of the lake.
