Mr. Teijsmann has the great merit of having been the first to introduce into Java the cultivation of the valuable and costly Vanilla plant (_Vanilla planifolia_), by using artificial means of fructification, after all the many expensive experiments previously made had failed, because the insect which effects the fructification of the plant in its original climate, the West Indies, is not found in Java. At present the yield is so great, that not alone does Mr. Teijsmann annually secure and send to market several hundredweights of this aromatic pod, but several other landowners have applied themselves to the laying out of Vanilla plantations. The fruit, from six to ten inches in length, by three to five lines in width, of a dark brown colour, flexible, and somewhat unctuous to the touch, requires about five months to ripen. They are carefully dried, first in the shade and afterwards in the sun, and are then packed away in bundles in air-tight metal cases. One hundred pounds of fresh pods yield about one pound of the Vanilla of commerce. Formerly the value of a pound of Vanilla was as high as 6 sterling, but it is at present sold at about 4.

In the beautifully situated Hotel Bellevue, where we lived while at Buitenzorg, we chanced to become acquainted with a curious individual, a young negro named Aquasie Boachi, son of an African prince of Cooma.s.sie, the chief city of the kingdom of Ashantee on the Gold Coast,[44] who, while a child of nine years, had been sent by the colonial government to Europe, in order to be educated in Germany. It was the intention to make apparent what early education and instruction can do for the negro, and how the present low state of the black race is princ.i.p.ally attributable to their oppression hitherto, and to the limited application, in their case, of European civilization. The experiment proved most satisfactory. Aquasie Boachi speaks German, English, Dutch, and French quite fluently, and holds a diploma, as mining engineer, from the mining academy of Freiberg in Saxony. He is a pupil of the celebrated Professor Bernhard Cotta, whom he still remembers with affection and grat.i.tude. As Aquasie had become a Christian he could not, save at the risk of his life, return to his heathenish native land, to the bosom of his own family. The Dutch Government accordingly, regarding him in the light of a victim to philanthropical experiments, at present pays the young miner out of the state funds about 400 per ann., and occasionally employs him on mining researches. Aquasie had resolved to settle for life in Germany, where, as he told us, he felt himself thoroughly at home, but the climate did not agree with him, upon which he returned to Java, and had since occupied himself in coffee-culture.

From the terrace of the hotel one enjoys a magnificent prospect bounded by the mountains around. On the right rises a lofty peak, whose summit-cone has been cloven into three pinnacles, the Gunung Salak 7204 feet (English), an extinct volcano, from which, however, in 1699 issued immense volumes of sand and mud, accompanied by columns of flames, tremendous bellowings, and convulsions of the soil. The torrent of liquid mud hurried along trunks of trees, carca.s.ses of animals, tame as well as wild, crocodiles and fish, and, still preserving its character of a mud torrent, rushed into the sea near Batavia, stopping up the mouths of several rivers and brooks. Since then this colossal hill, torn to its innermost core by this fearful eruption, has remained silent, and peaceful fields, alternating with luxuriant forest, stretch upwards to the very flanks of its once dreaded summit. To the left of Gunung Salak, and in appearance and elevation far more imposing, stands out the Gedee Range. Its highest point is the tapering regular cone of Gunung Pangerango, still further to the left of which rises, almost equal in height, the bare rocky wall of the still active crater of Gunung Gedeh, from the abyss of which there occasionally issued light clouds of vapour. But this exquisite landscape unveils itself to the ravished view of the beholder only during the early hours of morning. By 10 A.M. thin vapours have gathered round those lofty summits, which gradually acc.u.mulate as noon approaches, until by 3 P.M.

there is almost invariably a dense ma.s.s of clouds resting over the entire range, which very frequently dissolve with fearful violence in the shape of tremendous tropical thunder-storms. The annual rainfall at Buitenzorg would seem to be higher than at any other spot on the face of the earth.

During some years it occasionally attains the depth of 200 inches (English), which is far beyond the utmost known in Central or Southern America.[45]

The evening we spent at the residence of M. Van de Groote, inspector of the tin-mines of Banka and Borneo, who was of very great use to the geologist of the Expedition, and at whose hospitable house we met a number of personages of distinction.

On the following morning (14th May), before prosecuting our journey, we made an excursion to the neighbouring Batoetoelis (p.r.o.nounced Batootoolis), as a number of trachytic rocks are called, to which young Javanese wives, who wish to become mothers, ascribe the most marvellous virtues. The inscriptions hewn on the stones have been deciphered by the German philologist, Dr. Friedrich. There is also shown a stone with a depression like a human foot, which tradition a.s.serts to be the footstep of a native prophet, who is supposed to have stood thereon at a time when the ma.s.s was not yet solid and hardened. There evidently is some a.s.sociation of ideas similar to that of the Cingalese respecting Adam's Peak, but without the poetic colouring of the latter.

From Buitenzorg we went to Tjipannas,[46] a country-seat of the Governor-general, at the foot of Pangerango. The road from Buitenzorg to Tjipannas is part of the great post-road from Batavia to Surabaya, which just at this point traverses the mountain pa.s.s of Mengamendoeng, 4925 feet high, an outlier of the Gedeh range. It pa.s.ses at first through richly-cultivated properties, with splendid rice-crops, and a little further on through coffee plantations, after which comes uninhabited wilderness, when the road becomes so steep that a pair of buffalos are harnessed in front of the horses of each carriage. _En route_ we visited at Pondok-Gedeh the beautiful property of the family of Van den Bosch, whose founder greatly distinguished himself in promoting the agricultural prosperity of the island, while Governor-general of the colony, 1830-33.

In the extensive gardens here we saw several large species of _Vanilla_ and _Cactus_ (_Nopal_), the latter of which are devoted to the propagation and gathering of the diminutive cochineal insect, from which is procured such a valuable dye. In 1826, a pair of this very fecund insect were brought from Spain to Java, and at present[47] there are in Pondok-Gedeh alone 500,000 plants, from which between 10,000 and 20,000 pounds of cochineal are obtained annually, while other gardens of Nopal of equal size occur elsewhere throughout the island. We were also filled with astonishment at the variety and richness of the brushwood and forest trees, which the European is accustomed to see only as diminutive, tender specimens, the rare plants of a hot-house! Under the influence of a tropical climate, and a fruitful soil, the tea plant, the nutmeg, the cinnamon, the sugar-cane, the coffee bean, and the indigo, all flourish in wildest profusion, and the various warehouses are as crammed with the splendid produce of these valuable colonial staples as our northern granaries are with the necessaries of subsistence in the shape of dried fruits.[48]

Quite close to Pondok-Gedeh, amid the majestic mountain scenery of Gadok, is the _maison de Sante_ of Dr. Steenstra Toussaint, which enjoys a well-earned reputation under the management of Dr. Bernstein, a German physician and naturalist. Invalid residents of the coast, when recovering from climatic diseases, make a point of hurrying to this inst.i.tution, in order to benefit by the keen, bracing mountain air. Dr. Bernstein is, as far as his professional engagements will admit, at once a zealous collector, and a skilful preparer, who has already made some very beautiful collections, and who, if he stay here any length of time, will be in a position to enrich considerably the museums of natural history in Europe, with numerous rare and valuable specimens.

Just at the summit of the pa.s.s of Megamendoeng (dark cloud), begin the Preanger Regencies. This pa.s.s moreover forms a boundary line between the Malay language, chiefly used for commercial transactions along the coast, and that of Sunda, the difference between which two idioms, as regards the uninformed stranger is only so far important, that in asking a native for a light for his cigar, he must now say "Sono," instead of "Api," as. .h.i.therto, always supposing that he is a smoker, a qualification which rarely fails to appertain to the inhabitants of the Dutch East Indies.

Here, in a wooden building open on all sides, and commanding an exquisite panoramic view, we partook of a _dejeuner a la fourchette_, prepared quite in the European style, after which, amidst a drenching thunder-plump, we pursued our course to Tjipannas, which lies about 1000 feet below the level of the pa.s.s.

At every village we pa.s.sed, the authorities, as is the custom of the country, provided us with an escort. Thus we almost constantly had some 20 or 30 persons riding behind our carriages. The poor people had indued themselves in their best apparel, and looked very pretty in their varied fantastic attire. Even the rain, which still continued to descend in torrents, did not prevent them from following us, in order to do justice to the requirements of Javanese etiquette. So too, every one whom we met on the road a.s.sumed a respectful att.i.tude, resting on the knees in a half-kneeling position, and cowering down in the road with folded hands, till our vehicle had rolled by. All the villages we saw had a very neat, clean, cheerful appearance. The houses of the Javanese (with the exception of those of the native authorities) are as a rule built entirely of bamboo, part being of wicker-work, part of the cane placed either side by side, or above each other, the whole roofed in with palm-leaves, or Allang gra.s.s (_Imperata Allang_), or narrow shingles of cut bamboo, and with a flooring raised two or three feet above the level of the soil. The beautiful yellow wicker-work is usually stained in alternate squares of so black a colour that the walls of a Javanese hut resemble nothing so much as a gigantic draught-board. Under the eaves of the dwelling, which project five or six feet, and is supported in front upon poles, so that there is a sort of verandah beneath, are suspended cages with various feathered inhabitants, which the Javanese cherish with much tenderness, or else a very peculiarly constructed bee-hive, consisting of a bamboo-cane, six or nine inches thick by three or four feet in length, which is split through the centre, hollowed out, and fastened together again on the upper side.

Through a small orifice left in front, this artificial cavity is within a week or two peopled with a swarm of tiny stingless bees (_Meliporia minuta_) which in the wild state inhabit the holes and cavities of the calcareous cliffs, and provide the Javanese with honey and wax. The latter product is blackish, slimy, and adhesive, and is employed in the delineation of the beautifully coloured figures in the gowns (_Sarongs_) of the native women.

[Ill.u.s.tration: Javanese Bee-hive.]

At the station of Tjianjawar, we were saluted, while changing horses, by a Javanese chief, from Tjiangoer, named Radben Rangga Padma Negara, who, despite the tremendous tropical rains, accompanied us on horseback in his rich uniform, overlaid with gold lace, as far as Tjipannas, where we were received by two government officials, and welcomed with the utmost cordiality. Here it was arranged we were to pa.s.s the night, so as, early the following morning, to make the ascent of Gunung Pangerango. We also found awaiting us a letter from Dr. Junghuhn, the renowned geologist and writer on the natural history of Java, who for years has resided about a day's journey from Tjipannas, at Lembang, at the foot of Tankuban-Prahu, and has latterly been engaged by government to superintend the china-plant cultivation. Dr. Junghuhn had come to meet us as far as Tjipodas, where the first attempts at cultivation of the china plant were being made with roots imported from South America, but, owing to a press of important business, was compelled to return to his own station before we reached the Preanger Regencies. This estimable German gentleman urgently besought us, by letter, to visit him in his forest abode, and painted in the most glowing colours the wonders of Nature, and the interest in a scientific point of view of his mighty mountain neighbour. At the same time he sent over his learned a.s.sistant, Dr. de Vrij, to welcome in his name the Austrian travellers, to explain to them in all their detail the Cinchona-plantations at the foot of Pangerango, and to enlighten them as to the present condition and prospects of this very important branch of cultivation.

On the morning of 15th May we set off on horseback for the Pangerango, which was covered with dense vapours, which wholly concealed it from view, and rather damped our hopes of enjoying a fine view from the summit. A path for horses has been made to the very top, and although at certain points this pa.s.ses over exceedingly steep ground, yet the Javanese horses climb with such safety and dogged perseverance, even in the most dangerous spots, that one may leave these small but powerful animals to choose their way, with as much confidence as in the case of that most sure-footed of animals, the mule of South America. Our cavalcade consisted of thirty riders, while an immense number of natives took on themselves the duties of an honorary body-guard. The forests, usually so lonely, were now alive with hundreds of men, busy transporting our horses, provisions, couches, tables, and stores, which were all to be conveyed to the highest peak of the mountain, where we intended to spend the evening. After we had attained a considerable distance from Tjipannas, constantly ascending till we were about 4000 feet above it, we found the flanks of the mountain quite free of wood. The traveller sees a few villages scattered at random, and rides over gra.s.s pasturages, on which are feeding troops of buffalos, alternating with plantations of tobacco or coffee. But at the very point where the forest gradually begins, where gigantic trees have been left standing like so many sentinels, there it is that the amazed European falls in with most luxuriant beds of artichokes and strawberries, and is welcomed on this distant soil by all the well-known fruits of his remote home. The path leads past Tjipodas, into a deep narrow valley, overgrown with the most luxuriant vegetation, and thence through a forest of indescribable majesty, filled with the straight, tapering, pillar-shaped trunks, 80 to 100 feet in height, of the imposing Rasamala (_Liquidambar-Altingiana_), and a thoroughly tropical underwood of wild _Musaceae_, and splendid tree-ferns, till finally the broad plateau-shaped Tjiburum (red-water) is reached. Here at an elevation of 5100 feet we found some Pasanggrahans, or resting-houses, erected by government for the shelter and accommodation of all travellers through these mountain solitudes, who may happen to be surprised by night, or inclement weather.

Such hostelries are found everywhere in the interior of Java, especially in those districts where they are most likely to be needed by European travellers, or by government employes, during their frequent tours of inspection, in which they occasionally undergo severe privations. At Tjiburum, lying far above the regions inhabited by man, there is a small nursery of useful plants of colder climes, bearing ample testimony to the indefatigable activity of Mr. Teijsmann of Buitenzorg, to whom the community is moreover chiefly indebted for the laying out of the entire road to the summit of the mountain. As there was every indication of a severe storm coming on, and as we hoped by pressing forward to get to our goal before it should burst, we halted here only long enough to change horses. This done we again resumed the ascent, much refreshed by the delay, which imparted renewed vigour to climb the steep zig-zag pathway, which now led through a gloomy, silent forest, whence not a sound issued except the _blowing_ of our cattle, as they breasted the steep, and far below us the hollow roar of the mountain brook, which swept through the valley beneath. We then found ourselves approaching nearer and nearer to some resounding torrent, which went on increasing, till to our amazement we suddenly perceived amid the keen cool mountain breezes a smoking cascade of hot water!! (_Tji-olok_, or Sulphur spring). This warm spring, with a temperature of 113 Fahr., which even at its source forms a tolerable-sized brook, issues with much spluttering from a trachytic rock close by the way-side, and rushes, brawling and foaming, down a narrow defile, overgrown with splendid tree-ferns, and which is crossed by means of a slight rustic bridge. Scarcely is it possible to conceive a richer landscape, recalling as it were the primeval days of earth in all the luxuriance of Nature in the flush of youth, than this forest of tree-ferns, enveloped in clouds of warm vapour, which rise from this volcanic spring, close alongside of a clear, cold mountain torrent, which just here leaps into the same chasm! This hot spring thus early indicates the presence of volcanic fires, which is further evidenced by a tract of volcanic debris, over which it is necessary to clamber, and which has been ejected by the destructive energies of the neighbouring active crater of Gedeh, from which the subterranean forces usually throw up, not red-hot lava-streams, but from time to time tremendous stone and mud currents, which, rushing down the steep flanks of the mountain, overrun and destroy everything around.

About 10 A.M. we reached Kandang Badak, or the spot where rhinoceroses a.s.semble, which is the second station, 7200 feet above sea-level. Solitary specimens of the formidable animals which have given their name to this place are still met with here; but a troop of some hundred men, accompanied by almost as many horses, must necessarily make such a din in the usually solitary forest, as at once to account for our being unable by personal observation to speak as to whether it deserves the name it has received. The rhinoceros, despite his immense size, is a shy, timid animal, who flees before man, and only attacks him when fairly compelled to do so in self-defence. The Pasanggrahan erected at this spot has several times already been burnt down by red-hot stones ejected from Gedeh. Here the path divides, one branch leading to the still active crater of Gedeh, which can only be reached on foot, the other leading to the summit of Pangerango. For the second time we changed horses, and now had the last bit of the way before us--the steep, almost precipitous, cone of Pangerango. It was enveloped in thick clouds, and it was only by the short windings of the path we could realize that we were riding up an isolated cone of regular form, the slope of which was between 25 and 30 degrees. The cool air of these elevated regions now began to make itself felt, while our sensations bodily testified to the northern character of the vegetation around us. The tree-ferns indeed continued to grow up to the very highest point, but long ere reaching the summit they ceased to be found among the gigantic forest-pillars of the _Liquid-ambar_, but grew between dwarfish, knotted, stunted trees, whose trunks were overrun with a bright green moss, while from the branches hung festoons of greyish-green beard-moss (_Tillandsia usnioides_), greatly resembling hair. The trees, instead of stretching out their brown limbs to the air and light above, left them to droop sullenly to the ground, turning themselves, as though in pain, away from the rude wind which swept through their branches, and, as it were, seeking for warmth and sustenance from mother Earth alone. All the plants here showed a tendency to become creepers, as also to a circ.u.mscribed growth and extent of foliage, as well as uniformity of species. By 3 P.M. the whole party, including a rear-guard of irregular naturalists and sharp-shooters, had finally reached the summit of the mountain. When Dr. Junghuhn, the first man who trod this solitude, made the earliest ascent of this mountain in 1839, he found not a trace of a human step, and had painfully to make his way by rhinoceros-paths, beneath a thick overhanging canopy of leaves, and through dense underwood. Thus he finally succeeded in forcing a pa.s.sage through the forest, till he emerged upon a naked patch in the middle of the peak, where a rhinoceros was lying in the middle of the stream, while another was browsing on the edge of the forest: they fled snorting away on beholding him. How different was what we now witnessed on the same spot!

The flat s.p.a.ce on the summit, somewhat concave in shape, and sinking gradually away, the deepest part being towards the S.W., whence issues the highest spring in Java, now resembled the bivouac of a detachment of troops. Everywhere were men and horses, with cheerful blazing fires for cooking and warming, while immediately adjoining a strawberry garden filled with delicious fruit, rose a hut for shelter against wind and weather, in which we found a surprising degree of comfort. Tables, chairs, beds, excellent provisions and drinkables, were ready for us at an elevation of more than 9000 feet above the level of the sea, so that there was nothing wanting which could in any way contribute to our comfort. Even the necessary warmth was supplied by a huge iron stove, constantly kept supplied with fresh fuel by a Javanese servant, cowering on the ground.

This was the more necessary that our systems, accustomed of late to tropical temperature, were unusually susceptible to this sudden and extreme change. In the morning when we left Tjipannas the thermometer even at that early hour marked 70, while the mercury had now sunk to 48.22 Fahr. The longings we so often expressed, during a sojourn for months together on the bosom of the ocean, amid the moist, sultry strata of the lower atmosphere, in an almost unvarying Turkish-bath-like temperature of 86, of being once more re-invigorated by a little cold, were now being gratified to the letter.

Unfortunately our antic.i.p.ated enjoyment of the view from the summit was entirely frustrated by rain and cloud: we could hardly see anything a hundred yards distant, and the only idea we could form of the gigantic mountains and splendid hill-scenery that we knew surrounded us on all hands, had to be derived chiefly from the topographical charts we found in the hut. It was only during the occasional fleeting glimpses, when the S.E. trade-wind of the upper atmosphere, generally the chief ruler of these lofty regions, and almost always accompanied by a pure, blue sky, overpowered the N.W. trade (which blew from beneath; and, trending upwards along the cleft in the western side of the crater of Mondolaw.a.n.gi, continually enveloped anew in clouds the summit of the Pangerango), that it was permitted us to descry, now here, now there, small stretches of the country lying spread out at our feet, or to perceive closer at hand the inner slope of the crater of Gedeh, lying exposed to our wondering vision.

We did what we could to secure a few thermometrical and barometrical observations, as also to shoot, to geologize, to botanize; and many a valuable discovery was made ere night set in and compelled us to seek shelter against the raw, cold night air, in the Pasanggrahan, which had been so carefully fitted up for our accommodation. On the summit we found quite an acc.u.mulation of various elegant little plants, which recalled to us the Alpine districts of our own land, one of which, first discovered by Junghuhn, and named by him _Primula Imperialis_,[49] is one of the loveliest flowers in Nature, and which has never yet been found in any other part of the globe; while in the brushwood around we heard the cooing of a bird of the thrush species (_t.u.r.dus fumidus_), which, with the exception of a small, very elegant little fellow, somewhat resembling the willow-wren, was the sole representative of the feathered tribe in these elevated regions.

All our hopes were now directed towards the ensuing morning, which it was hoped would bring us better weather. By five in the morning every one was on foot, watching with anxious look the advent of the star of day. But alas! ere long all was once more enveloped for us in a dense but fine vapour, and the thermometer indicated only 47.33 Fahr.

About fifty feet higher than the two huts for shelter erected on the plateau rises a trigonometrical pole, which, visible from a great distance, serves as a land-mark for the government surveyors during their labours in this neighbourhood. Any clear morning, when the sky is free from clouds, one must enjoy from this free, airy out-look a splendid distant view over a large portion of the Preanger Regency. As for ourselves our panorama continued to be lamentably circ.u.mscribed, and all we could do was, to watch for those fleeting moments during which the clouds lifted and gave us a brief yet comprehensive glimpse of the wondrous natural beauty of the surrounding landscape.

Pangerango, 9326 Paris, or 9940 English, feet in height, is the loftiest of the extinct volcanic cones of Java, rising on the eastern slope of an enormous crater-gulf, likewise extinct. Close in the vicinity, not above a mile distant to the S.E., and communicating with it by the ridge of Pasce Alang, 7000 (Paris) feet in height, rises another volcanic peak, Gunung Gedeh, of almost precisely identical height (9323 Paris, or 9937 English, feet). Its summit has fallen in, and from amid the debris on the floor of this ruined crater rises a second cone far less in height, but in full activity, with a deep crater, which is the true fiery gorge of the still active Gedeh. Towards 7 A.M. the clouds dispersed for a considerable s.p.a.ce, when directly opposite us we saw the beautifully regular cone of Gedeh, with its perpendicular precipitous crater-wall, some 600 or 700 feet high. So near, indeed, did it appear to the eye that we could almost fancy it possible to throw a stone from the one summit to the other, so that it should fall exactly into the crater, from amid whose rents and cavities thick volumes of smoke were bursting forth at several points.

By 10 A.M. our caravan was once more under weigh on our return to Tjipannas. The geologist of the Expedition, however, accompanied by Dr.

Vrij and one of the government employes, set off upon a rather dangerous adventure, viz. the ascent of the Gedeh. Of this interesting excursion, Dr. Hochstetter gives the following interesting details:--

"A short distance before reaching the station of Kandung Badak, the path leaves the road by which we had come thus far. Here we had to clamber upwards as best we might, by a narrow path densely overgrown, and evidently but rarely traversed, till presently we emerged from the forest upon a tract of loose stone and scoriae, which, spa.r.s.ely covered with low bushes and gra.s.s, forms the upper portion of the peak of Gedeh. A strong odour of sulphuretted hydrogen greeted us here, issuing from a Solfatara, which nestled under the true crater in a deep savage cleft of rock. Hot sulphureous and watery vapours were emitted from among the dark crannies of the rock, the upper edges of which were coloured yellow with pure sulphur: with much difficulty we still pressed on, and finally reached the edge of the ruined crater. What a contrast presented itself here in the view before us and the landscape behind!

"Behind we could see from base to summit clear and unbroken the beautiful luxuriantly-green well-wooded peak of Pangerango, on whose highest point stood out near and distinct the trigonometrical pole, or land-mark, while from the forest was heard an occasional musket-shot, sure sign that the company of travellers from the ship were on their way down. On the other hand, when we cast our eyes forward we saw but dismal desolate groups of grey rock, around the lofty amphitheatre-shaped rock wall of the broken-down lip of a crater, regularly constructed of pillar-like ma.s.ses of trachyte, each sundered from the column immediately adjoining, beneath which was the smoking cone of the active region of the crater, a bare heap of stone and scoriae, of the utmost variety of colour. Stretching from the vast abyss of the crater-ruins, on whose bald slope is situated the cone of the new eruption, there is visible at intervals on either side, far down, until indeed it is lost in the dark gloom of the forest, a bare rocky ravine, full of stones and debris, which the active vent of the crater has from time to time vomited forth. We had on the previous day pa.s.sed the lower extremity of this stream while riding to Pangerango.

"But we were not yet at the goal of our wanderings. We still had to climb from this point, and afterwards to scramble up to the summit of the active cone. This, however, proved to be much more easy than we had thought when looking at it from below, and we arrived without any disaster at the summit.

"Here then we were standing upon the edge of a yawning crater, in full activity! Not a single step forward was it possible for us to make. In front of us lay a funnel-shaped slope, 250 feet in depth, the floor of which was covered with mud, in which stood frequent pools of boiling water of a yellow tinge. The Javanese who accompanied us stated that they had never before seen it so quiet, the crater having always been quite full of steam and vapour. On the present occasion the steam only escaped in small volumes through a few fissures in the sides of the inverted cone, and more particularly from the cracks and crevices on the exterior of the cone of scoriae. We could perceive only water, steam, mud, and sharp-cornered fragments of rock, the debris and rubbish formed by the disintegration of the rocky ma.s.ses thrown up by the crater, but not a trace, not a vestige, of any molten stream of lava, heaped up by the present crater of Gedeh. The whole history of the activity of this volcano may be compared to the explosions of a vapour cauldron in the interior of the earth, which has been heated by the ma.s.ses of old trachytic lava currents in an incandescent state, but not yet thoroughly cooled, whose eruptions formed the princ.i.p.al means of erecting the volcanic cone.

Repeatedly up to our own times has the mountain thrown up water, mud, and stones, together with fine powdered sand and volcanic ashes, which have travelled as far as Batavia, as also ma.s.ses of melted stone cemented by liquefied sand, while marvellous volumes of flame were visible to an immense distance; but at no period within the memory of man has the Gedeh poured forth the hot liquid lava, or thrown up into the air melted volcanic matter. We must regard it as in its last stage, as about to become extinct, like all the other volcanoes of Java. It is the last reaction of the internal fires against the atmosphere penetrating from without. Even the most active volcanoes of Java, such as Gunung Guntur and Gunung Lamengan eject only ma.s.ses of liquefied rock and scoriae, cemented by the heat, but the regular lava currents have never been observed."

While Dr. Hochstetter was occupied with this excursion to the active crater of Gedeh, the remaining members of the Expedition had reached Tjipodas at the foot of this fire-mountain, where, at an elevation of 4400 feet above sea-level, and at an annual average temperature of 63.5 Fahr., the first attempts were made to acclimatize in Java the valuable quinquina tree (_Cinchona sp._).

Although for twenty years past the introduction into Java of the cultivation of the quinquina tree, the bark of which is of such superlative importance for suffering humanity, had been repeatedly tried, this praiseworthy intention was only successfully carried into effect in 1852, through the purchase of a specimen of _Cinchona Calisaya_ from the _Jardin des Plantes_ at Paris by the then colonial minister of the kingdom of the Netherlands, M. Pahud, afterwards Governor-general of the Dutch East Indies. M. Pahud had the plant brought to Leyden with the utmost care, whence it was conveyed to Rotterdam for shipment to Batavia.

Immediately on its arrival this plant, the progenitor of all that have been grown since, was placed in what is called the Governor-general's strawberry garden in Tjipodas, where it was protected by a bamboo shed from rain and sun, and at the time of our visit was 16 feet high. Dr.

Ha.s.skarl, widely renowned as a botanist, was, on the recommendation of Dr.

Junghuhn, who had himself been urgently requested to undertake the duty, entrusted with a mission to Peru, whence he was to bring back offshoots, and germinating seeds, of the various species of Cinchona from which quinine is obtainable. Two years later, a Dutch man-of-war was specially despatched to Callao, the harbour of Lima, to convey Ha.s.skarl with his valuable booty. That gentleman accordingly brought away with him four well-rooted young trees, and the seeds of four species of Cinchona,[50]

but only the saplings gave promise of success, whereas the greater part of the seeds, on being sown, were lost. M. Ha.s.skarl has had the reproach cast upon him, that during his expensive residence of two years' duration in Peru, he should have collected such few data of the higher and lower limits of vegetation of the China plant, and the conditions of soil and mountain temperature under which it best flourishes, of the general influence exercised on it by storm and humidity, as also upon the annual quant.i.ty of rain it requires, whether a shady or sunny place of growth be best adapted to it, the period of flowering and fructification, the alterations which may be rendered necessary by its habits of growth at various points, as to what are its natural enemies, and how far its alkaloid properties are affected by the greater or less elevation above the sea of the spot in which it is growing, &c., &c. Nay, some persons went so far as to allege that the botanist had never seen one single China plantation, and had never personally selected either the plants or the seed, but had made arrangements for being supplied with the specimens he brought by means of the native bark-collectors (_Cascarilleros_). As though still further to enhance the public discontent with Ha.s.skarl, and the failure of his expensive mission, fate unhappily willed that his wife, who was said to be bringing with her his papers and memoranda of his stay in Peru, was lost, together with the vessel which, after several years'

separation from her husband, was about restoring her to his arms, in consequence of which many questions relating to the cultivation of the China plant in northern and southern Peru remained unanswered! Ha.s.skarl ere long returned to Europe "for his health," and the superintendence of the China cultivation was in June, 1858, committed to Dr. Junghuhn, in whose careful charge it now is, and has taken a start which leaves no room to doubt its ultimate and permanent success.

In October, 1856, there were in Tjipodas 105 China trees of 2 feet 6 inches high (41 of _C. Calisaya_, 64 of _C. Condanimea_). On 31st October, 1857, there were only 95 about 4 feet 11-1/2 inches in height, all in flourishing condition, while 10 had died. The cause of this lamentable phenomenon could not long escape the piercing glance of Junghuhn. The first tender shoots had been planted in a Tufa soil, the fertile covering of which barely exceeded 6 to 9 inches in thickness, and were surrounded by roots and stumps of immense forest trees that had been cut down, which of course prevented anything like expansion, and, in a word, completely stifled their growth.

In the case of the earlier plants, there was far too little attention paid to the requisite amount of shade. The timber had been entirely cleared away, and the young plants were consequently exposed during the whole day to the fierce heat of the tropics. Unless people were prepared to see the whole plantation go to ruin it was necessary at once to take protecting measures against it. Junghuhn was a man fit for any emergency, as he had already shown on the banks of his native Rhine, when the very cells of Ehrenbreitstein, with which a chivalric adventure had made him acquainted in his youth, had for once been found too narrow to hold him. So in Tjipodas, the man of resources was able at once to devise a remedy. With incredible toil, and the most fostering care and attention, nearly all the trees were, without detriment to one single twig, transplanted from a soil so little congenial to them to the adjoining Rasamala-wood, in which the proud, slight _Liquid-ambar Altingiana_ imparts its own peculiar character to the primeval forest, where they were transferred to spots partly shaded, which had already been prepared for their special reception, the sites having been surrounded with trenches to carry off the superfluous water. In October, 1857, some of the trees had already attained a height of 14-1/2 feet; by 31st March of the following year they were already 15-1/2 feet, while their stems were 3.44 inches thick. Many of the trees planted near the forest had within three months grown from 9 to 21 inches, while the few that remained on their old site had only gained 9 or 10 inches in height, a fact which seemed incontestably to prove that the new site was the better adapted to them. In June, 1857, the first blossom had made its appearance on one of the _Condanimea_, but it was not till May, 1858, that the majority of the trees were in full bloom, or that the ripening fruit began to make its appearance. When all the fruits ripen, Dr. Junghuhn told us he was in hopes he would secure 80,000 fruit, which, as each fruit contains about 40 seeds, would provide him with 3,200,000 seedlings. It is not indeed a question merely of ripe and at the same time fertilized seeds, but chiefly whether the bark of this plant contains in the land of its adoption, and under different conditions, that costly alkaloid quinine, which seems daily to become more indispensable in the science of medicine.

Despite the most anxious solicitude there had long been remarked in Tjipodas a gradual decay of some of the shoots, but it was only a few days before our arrival that after a most minute zealous inquiry the cause of this phenomenon was discovered. A minute insect, scarcely 1/25 of an inch in length, of the _Bostrichus_ species, proved to be the foe of these plants. The holes which are burrowed by this insect, are drilled quite through the wood of the stem and branches into the very pith, in which it finally stops and lays its eggs. The Cinchona trees thus bored through are irremediably ruined, but there is always the hope that, as the roots remain sound, they may afterwards put forth new shoots. However, the appearance of this insect does not seem to be the primary cause of the disease of the trees,--on the contrary, disease is the cause of the appearance of the insect. If the other trees prove to be successfully reared, the insect will disappear, since it was convincingly proved by one of our zoologists that it had not come to the country with the Cinchona seeds and plants, but was undoubtedly indigenous to Java.

Altogether there were, in May, 1858, upon the whole island three quinquina plantations, which have been specially established with a view to the solution of certain questions of climate at various elevations, and are situated in the following localities:--

1. In Tjipodas at the foot of Gunung Gedeh (4400 to 4800 feet above sea-level), in a beautiful Liquid-ambar forest, and containing 80 plants.

2. In Bengalenzong, on the declivities of the Malabar Range (4000 to 7000 feet in height), in the midst of a considerable oak forest (_Quercus f.a.gifolia_), containing 600 plants.

3. South of Besuki on the Ajang Range (about 6800 feet above sea-level), in a plantation[51] containing 21 plants, to which Dr. Junghuhn gave the name of Wono Djampie, i. e. Forest of medicines.

The Dutch Government has spared neither trouble nor expense, and has made considerable sacrifices, to bring over the quinquina plant from its native country, where it was believed to be threatened with utter destruction, to Java, there to be acclimatized. The chances in favour of an adequate return are very great, and the attainment of this object has been secured within certain limits. Of all the tropical regions we visited, the Island of Java seems by its natural advantages to be the best capable of affording to the tree which produces the febrifuge bark, so invaluable a boon of nature to suffering humanity, a second home, amid the magnificent scenery of its mountain ranges.

However, the wide-spread idea that the China plant is exposed to utter extinction in its native land of Peru has proved to be quite unfounded. We shall revert to this subject when we come to treat of our visit to the western coast of South America, and shall take pains to solve at least some portion of the question in dispute, as to certain necessary conditions being requisite to be observed in the case of the quinquina plant in its original home, the investigation of which, the superintendent of the quinquina tree culture in Java, Dr. Franz Junghuhn, so earnestly commended to the attention of the scientific members of the _Novara_ Expedition.

However, our interest was not confined to these China-tree plantations; our attention was riveted by the marvellous Rasamala (Liquid-ambar) forest in which we now found ourselves, while those fond of the chase were not less amazed and gratified, at bringing down a splendid specimen of what is known as the Kalong or Roussette Bat (_Pteropus vulgaris_). These singular nocturnal animals hang in enormous quant.i.ties throughout the entire day from the branches of the trees, amid the profoundest stillness, till evening sets in and dismisses them to their nightly evolutions. They are then visible flying through the air like gigantic bats, or flying foxes.

While riding back to Tjipannas we remarked amid the smiling rice fields several poles with hangings of various kinds, resembling those erected on the sh.o.r.e in front of their huts by the superst.i.tious natives of the Nicobar Islands, in order to keep his Satanic Majesty at a distance. The natives call these poles Tundang-Setan (talisman against the devil), and believe they can by their aid frighten away the evil spirits, while they are gathering the crop from their rice fields.

From Tjipodas the excursionists proceeded to Tjiangoer,[52] the present capital of the Preanger Regency, containing about 15,000 inhabitants, where some days were to be spent in excursions, collections, hunting, and other amus.e.m.e.nts, after which we were compelled by the limited time available to return to Buitenzorg and Batavia. Two members of the Expedition, Drs. Hochstetter and Scherzer, penetrated a little further into the interior, with the purpose of paying a visit to Dr. Junghuhn, to whose researches in the Natural History of Java we are so much indebted.

The following few pages are devoted to an account of this interesting excursion.

Towards 5 P.M. we arrived at Tjiangoer, in company with Dr. de Vrij and M.

Vollenhoven, and immediately set out on our journey to Bandong, so as to reach the same evening that neat little town, whose singularly favourable position, almost exactly in the centre of the Regency, makes it a dangerous rival to Tjiangoer as the seat of government. _En route_ we pa.s.sed Tjisokan, a small village, most of whose inhabitants are engaged in procuring edible swallows'-nests, which are found in great quant.i.ties at a chalk mountain about twelve miles distant, known as Radjamandula.[53] The spots at which the edible nests of the _Hirundo esculenta_ are found are anything but grottoes peculiar to this product, as is usually alleged, but steep, almost inaccessible, cliffs, crannies, and fissures in the rock, in which the swallows build their nests, and which can only be reached by the utmost exertion, frequently accompanied by danger to life. They are met with partly upon the south coast, close above the raging surf, partly deep in the interior, about 2000 feet above the level of the sea, distant several hundred English miles from the nearest part of the sea-sh.o.r.e; and while the inhabitants of Karangbolong have to scale the almost perpendicular coast-wall by means of ladders[54] of Rotang (_Calamus Rotang_) and Bamboo, ere they can reach the entrance of the cavern, the natives of Bandong, on the contrary, are compelled to climb up to a yet greater elevation among the precipices and rocks, ere they are able to reach the openings that lead to the various hollows.

While the birds are breeding, or if they have their young, which happens four times each year, one half remain in the cavities, and both males and females take their turns in sitting to brood, every six hours. Each nest is inhabited by a pair of swallows, so that if 1000 nests are found in a cave, they are inhabited by 2000 grown swallows (half male, half female).

The fecundity of this bird is so great, that, although the nests are gathered four times a year, and that somewhere about a million of their progeny is at each plucking wasted or destroyed by the collectors, they never seem to diminish. The six caves at Bandong give yearly about 14,000 nests, that at Karangbolong about 500,000: one hundred nests weigh about one _catty_ (1-1/4 lb.), and one hundred catties (125 lbs.) make one _picul_.[55] For each picul of these nests, which they look upon as a special delicacy, the Chinese pay from 4000 to 5000 guilders (350 to 420). The nest-gatherers are apparently a special cla.s.s, whose occupation is handed down from father to son.

Close to the village of Tjisokan, a very elegant wooden bridge, constructed on the American system, but entirely erected out of the resources of the colony, has been thrown over the Tjisokan river. The roads, although broad and kept in excellent order, nevertheless lead occasionally over hills so steep, that to descend them in a heavy carriage, especially considering the rapidity with which the Javanese drive, is exceedingly uncomfortable, and even dangerous, although the wheels are in such cases provided with a solid "_sabot_," and where this seems likely to prove inadequate, a number of natives hang on to the wheels behind, who for a small gratuity control the rate of descent by means of ropes.
