I do not intend dwelling on this expedition, as I only kept an account of the geographical features of the country, though Mr. Low has kindly placed his interesting journal at my disposal to refresh my memory. I will, however, briefly indicate the character of the mountain. We left our encampment and struck through the jungle to a spot that a previous examination made me consider the easiest way to pass the precipices. The rocks looked like broken masses which had fallen from above, presenting sharp points and edges dangerous to our unshod men. It was climbing, not walking, our hands being as much used as our feet. We ascended about 800 feet, when we found ourselves on a sharp edge with a valley beyond, and then descended about forty feet by means of roots, and after a painful advance made preparations to pass the night there, as our men were lagging. We could, however, nowhere find a smooth place broad enough to set up our tents; so threw poles across the rocks and heaped boughs and leaves on them, and on sticks above spread our piled cotton tents. We advanced next day over rather easier ground, and found more vegetable mould between the rocks; the trees were large, and among them I had seen on the previous day troops of reddish monkeys, equal in size to the small kind of orang-utan. We could find no water except such as could be obtained from squeezing the moss, or from the pitchers of two new kinds of nepenthes. It was on the third day that Mr. Low came upon them, after passing a deep gorge, and up a steep and fatiguing ascent over craggy cliffs, everything being covered with long wet moss. There were two kinds; the specimens, unfortunately, were lost by the men:--the first was shaped something like a claret jug, with a quadrilateral stem, and was of a pale green, except on the inside of the pitcher, which was purplish--the pitchers themselves were about ten inches long, and did not show the lower part in perfection except when full-grown. The next kind was growing half buried beneath the moss, and creeping closely along the stems of trees; its pitchers had a very peculiar mouth, with an edge like a frill. Its stem was rough with brown hairs, the leaves broad and short, and it was distinguished from all others we had yet seen, by the leaves, which are close above one another, giving off always to the right and left, and not on all sides of the stem as in the other species; they lie also very close; its stem was at most three feet long; the pitcher was about nine inches in length, not including the lid.
