narrow, steep ledge of the rock, which gradually lost itself among the vapour between two perpendicular, precipitous walls. We followed the Javanese, who were scrambling down before us, having ourselves given orders to be conducted if possible to the bottom of the crater, and therefore continued on as best we could, confident that those people had already often descended into the depths to get themselves sulphur.
"Fortunately the vapours dispersed during our arduous clamber, and there at one view lay plain before us the fearful chasm from its floor to the rim running round it. With amazement and surprise, we perceived that the ledge on which we stood was but a narrow central ridge, separating two deep nearly circular volcanic cauldrons, which were both surrounded by a lofty ellipse-shaped crater-wall! There was also a singular double or twin crater. In both cavities, right and left, white clouds of steam rose hissing and sputtering to the height of the rim. In the left-hand or western crater, which the natives called Kawah Upas, or the Poison Crater, we perceived in the midst of the smoking solfataras a tranquil pool of water of a sulphur-yellow hue, while the lofty internal slopes of the crater, nearly 1000 feet high, were densely covered with brushwood, down almost to the bottom. Very different was the eastern crater, Kawah Ratu, or King's Crater; its floor seemed to consist of dried mud, from the clefts and springs in which steam and sulphureous vapours were constantly bursting impetuously forth. The wall of this crater, not above 500 or 600 feet high, was naked and
bare to the very summit. At the first glance one could almost fancy he gazed on an expanse of snow amid a green forest, so bleached and greyish-white did everything look, owing to the rocks being pulverized and changed by the vapours which continually issued from the soil. Above these white desolate masses of rock were distinguishable the blackened, charred, knotted stems of bushes and trunks of trees, the relics of the vegetation formerly here, tokens of the last eruption in 1846, in which this King's Crater threw up boiling mud, impregnated with sulphur, besides sand and stones, till throughout an extended area the green forests on every side were killed or desolated. Already however the rich green of the fern, and the Thibaudia (not unlike our own whortleberry), is seen shooting up amidst the bare stones, in close proximity to the blackened trees and shrubs, charred and altered by the action of the sulphureous vapours and the soil, impregnated as it is with sulphur.
"Continuing to scramble forward, we reached in safety the floor of the Poison Crater, and had to observe the greatest vigilance, for the entire ground around the boiling lake in the crater to the steep walls consists of nothing but smoking solfataras, or a dense crust of sulphur, full of holes and fissures, over the cooled surface of which the traveller walks, constantly in danger of breaking through, not indeed into a fathomless abyss, but into boiling hot, bitter water, in which we would counsel no one to take a foot-bath. If the crust be broken off, there are seen shining beneath the most exquisite
lustrous crystals of sulphur. This sulphur, which is exhibited here piled up in immense masses like small hills, is the same as that which occasionally entices the Javanese into these appalling abysses. The most powerful solfatara, which lies exactly in the middle ridge, and like a geyser throws up to a height apparently of one or two feet a column of boiling water, consisting in part of sulphur, is for that reason unapproachable by man.
"From the Poison Crater we climbed over into the King's Crater. The hard masses of rubbish thrown out during the last eruption afforded firm footing here, until we got near the sputtering solfataras, when the hot yielding mud made further progress impracticable.
"The visit to these two craters, which change features from year to year, furnished much material for observation. It was long past noon when we retraced our steps upwards along the precipitous path by which we had descended. Ere long we found ourselves once more on the summit, protected from the sun's vertical rays by the grateful shelter of the hut which Junghuhn had erected here, and from which we could take in at one glance, in all its vast proportions, the entire abyss, with its two smoking craters in all their horrid sublimity. The oval of the exterior rim measures not less than 6000 feet in length by 3000 in breadth, and from the upper wall the descent sheer into the abyss is not less than 800 feet perpendicular.
"This was the last crater which we had an opportunity
of visiting while in Java—our further peregrinations being directed towards the schistose formation abounding in petrifactions, which is found in the S.W. mountain range of the table-land of Bandong.
"On the evening of the 18th, after we had returned from Tangkuban Prahu, we left Lembang, still in the company of Dr. de Vrij, who sacrificed his own convenience to accompany us throughout our interesting tour, and returned to Bandong.
