We continued our walk along the ridge until we had reached an elevation of 4,500 feet, when the path descended to the pleasant stream, or rather torrent, of Kina Taki, in which greenstone was the principal rock. All the rivulets we have passed to-day fall into the Dahombang, which continues its course until, winding round the bluff point of Labang Labang, it joins the Tampasuk. Another steep climb of 800 feet brought us to the Marei Parei spur, to the spot where the ground was covered with the magnificent pitcher-plants, of which we had come in search. This one has been called the _Nepenthes Rajah_, and is a plant about four feet in length, with broad leaves stretching on every side, having the great pitchers resting on the ground in a circle about it. Its shape and size are remarkable. I will give the measurement of a small one, to indicate the form: the length along the back was nearly fourteen inches; from the base to the top of the column in front was five inches; and its lid was a foot long by fourteen inches broad, and of an oval shape. Its mouth was surrounded by a plaited pile, which near the column was two inches broad, lessening in its narrowest part to three-quarters of an inch. The plaited pile of the mouth was also undulating in broad waves. Near the stem the pitcher is four inches deep, so that the mouth is situated upon it in a triangular manner. The colour of an old pitcher was a deep purple, but that of the others is generally mauve outside, very dark indeed in the lower part, though lighter towards the rim; the inside is of the same colour, but has a kind of glazed and shiny appearance. The lid is mauve in the centre, shading to green at the edges. The stems of the female flowers we found always a foot shorter than those of the male, and the former were far less numerous than the latter. It is indeed one of the most astonishing productions of nature. Mr. Low set to work enthusiastically to collect specimens, while I tried to procure some compass bearings; but the mist kept driving over the country, so that I had only one good opportunity. I rested the compass on a rock, and was surprised by its pointing in a very different direction from what the position of the sun showed it should. On raising it in my hands, it pointed correctly. I found, on examination, that the rock was covered with a thick coating of iron, and all in the neighbourhood were in a similar state. To-day we reached an elevation of 5,400 feet. The path we followed was tolerably good; we were told that it led to the village of Sayap, a branch of the Kiau tribe.
