"This stream of lava is bounded on the north by another, of the same nature and disposition, thrown out of the mountain (according to an estimate made from the commencement and progress of vegetation upon it) about thirty years ago. In its course along the sides of the mountain it forms the same pointed ridges above described. It affords a plain demonstration of the manner in which the surface of lava is decomposed and rendered fit for vegetation. A third district of lava bounds the new stream first described in the south: it is more extensive than the others, and consists of several distinct regions, probably thrown out during one eruption (which appears to have been more violent than the others), but in successive periods shortly following each other. It extends farther to the eastward than the others, and covers a great portion of the foot of the mountain. Vegetation has already made considerable progress upon it: in the vallies between the separate streams of lava are found not only plants but also small shrubs. At one place, near the termination of this stream, the lava is piled up in two irregular ridges to the height of twenty feet; and at a small distance from its eastern extremity, in a spot which has escaped the effects of the later eruptions, and is covered by pleasant wood, are three different hot wells, within the circumference of a quarter of a mile. In the south, this district of lava is bounded by a recent stream, which appears to have been thrown out in 1800, by the same eruption which produced the first mentioned stream. It differs from the others only in the colour of its lava, which has a reddish hue: it is less considerable in extent than any of the others, and cannot be traced far from the foot of the mountain. The fifth stream of lava which I examined is still farther towards the south, and is one of the oldest which have been discharged from the eastern part of the crater. Near the foot of the mountain, vegetation has made greater progress than in any of the other districts of lava. "The colour of the recent lava of this mountain is jet-black or grey: one of the streams only has a reddish colour. Its texture is very loose, and its fracture very porous. The smaller fragments have much the appearance of the scoriæ of a blacksmith's forge: on being thrown against each other, they emit a sound like two bricks coming into contact. The interior crater of this mountain, as it has remained after the eruption of 1800, is less interesting than the others which I have examined. Its shape is somewhat oval, the greatest diameter being about one hundred yards: its depth is not very considerable. Its structure, in general, is similar to that of _Tankuban-prahu_. It has one remaining aperture, which discharges with great force hot sulphureous vapours." _Batavian Transactions_, vol. ix.
