"_22d._--At five, when we rose, the thermometer stood at 56 deg. in the air. The head man had arrived, and willingly gave us guides, warning us only of the difficulty of the ascent. Nothing could exceed the kindness and attention of this simple old man. He remembered the time the English had the country, and spoke of his people's respect for our nation, and their regret that we had left the country. At 6 A.M. we started, and, after walking about a mile, plunged into the belt of forest which environs Lumpu Balong. From six till half-past two, we were alternately ascending and descending, scrambling over rocks or fallen timber, or cutting a path through the most tangled thicket that ever tore the wayfarer. To add to our difficulty, during the latter half of the ascent, we could procure no water, which caused us considerable suffering. At length, however, we stood at the summit of Lumpu Balong, and looked, on either side, over a vast sea of fleecy clouds which rolled beneath. The top is a narrow ridge, covered with stunted trees and luxuriant moss; and a second peak to the westward, of rather less elevation, is separated from it by a declivity. I climbed to the top of a tree to look along the mountain, and make certain that we were at the highest point; and having convinced myself of this, I proceeded with the barometric observations, which were concluded by 3 P.M.; for it was highly necessary to get down before night overtook us in the dreary and inhospitable forest. Our thirst, too, was tormenting, and increased by hearing the fall of a torrent deep in the valley to the northward.
