We awoke early next morning, but it was nearly eight o’clock before we started, owing to the dilatoriness of the Sĕbops in taking up their burdens. Before starting, and also on the previous evening, I photographed the Scott-Keltie Falls. The upper part of the falls is hidden by trees; the central portion consists of two large quadrangular faces of rock, one above the other, with a combined height of a hundred to a hundred and fifty feet. Below the fall proper is a steep declivity of fallen blocks of rock, many of huge dimensions, over which the water pours. Indeed, for a considerable distance down the steep river-bed is a mass of boulders which practically forms a continuous cascade. The vegetation about the falls was lovely, the masses of ordinary forest trees being relieved by graceful palms and shrubs of varied foliage (Frontispiece).
We ascended the mountain, leaving the falls on our right. It was very steep walking, and at places we had practically vertical escarpments of rock to negotiate, which were slippery owing to recent rains. The roots of trees and the stems of creepers afforded secure grip and foothold, but at a few places I was glad of the assistance of a ratan. We were in a mist the whole day, and every now and again a rift gave us tantalising glimpses of the outer world that far below us stretched out in all its tropical luxuriance and beauty. Sometimes we saw a bit of the river, and could just distinguish a village, when the view dissolved; then a neighbouring wooded spur of the mountain would shape itself out of the mist, only to disappear in the steamy atmosphere.
We pitched our camp about three o’clock, and made a long hut on the crest of a steep ridge at an elevation of over four thousand feet. Fortunately there was no rain all day, so our clothes were fairly dry, and we had no rain during the night. Of course it was chilly, but it was only really cold when the wind rose.
We got up on Thursday morning at 5.30. As soon as breakfast was finished, McDougall and all the carriers except Aris and one Sĕbop, who had a sore leg, continued the ascent. I was not very well, and did not feel equal to the climb, so I spent a quiet day, writing, and letting the influences of the jungle soak into me. It was a strange sensation perched high up on a narrow ridge in a tropical jungle and screened from the world by a mist!

McDougall returned about 3.30. He had ascended the highest point, which Hose has since named Cambridge Peak, but had not obtained a satisfactory view. He had some difficulty in climbing the uppermost escarpments. As the cliffs were absolutely vertical, the natives made ladders which they leaned against trees projecting from the cliff, and from one tree another ladder was raised to a tree above it, till the summit was reached. Mount Dulit is, in geographical terminology, a partially dissected block mountain of Carboniferous sandstone, the beds of which dip in a southerly direction.
There was rain early next morning, but it soon cleared for a short time, and we started on our homeward journey. We had a scanty lunch at the Scott-Keltie Falls. The water was now a thin stream, indeed we had noticed a difference in the amount on the Wednesday morning as compared with that which fell during our first evening there. We retraced our steps as quickly as possible, but I took several photographs of the falls and river. We got back to our boat about 3.30, and returned to Long Aiah Kechil before dark.
I was particularly interested in Mount Dulit, as it has been a happy hunting-ground for Hose during some years past. He was the first European to ascend the mountain, and he has made natural-history collections on it from top to base. Hose here discovered a high-altitude fauna, more particularly among the birds, which, like that of the famous Kina Balu in British North Borneo, has affinities with the fauna of the Himalayas.
The island of Borneo lies at one edge of an immense submarine bank, while the islands of Java and Sumatra are situated at its southern and western sides, and the island of Celebes and the archipelago that stretches from Java to Ombasi are annexes. The hundred-fathom contour line embraces this vast area, and indeed a considerable portion of the sea between Borneo and Java on the one hand, and Siam and the Malay Peninsula on the other, is only fifty fathoms deep. In other words, the trivial elevation of this area to three hundred feet would connect Borneo and Java with the mainland of Asia. This continental shelf may be termed the Malay shelf.
