“ ‘The gathering of these nests,’ ” continued van Rheijn still reading Murowski’s letter, “ ‘takes place three times a year. The first gathering begins in the latter part of April and is called “Oedoean kesongo.” The second begins in the middle of August and is called “Oedoean telor,” and the third, the “Oedoean kapat,” takes place in December. Now that kind of birdsnesting, my friends, is an occupation which I very willingly leave to the Javanese who make it their business. To gain the entrance of one of those caves they must clamber down the perpendicular face of the rock along ladders. The ladder, for instance, which leads to the mouth of the Djoembling cave is only 660 feet long. My heart beat high with desire to make a trip to these subterranean vaults. But—when I laid myself flat down and got my head over the edge of the rock while a couple of Javanese were holding on to my legs—when I saw that rottang ladder swinging hither and thither in the breeze sometimes clinging to the wall and then again curving inward and for a while lost to the eye. When, at a giddy depth below, I saw the huge breakers come tumbling in and forming there at the foot of the rocks a savage scene, a wild and whirling chaos of spouting water, of dazzling foam and of blinding spray. When my ear caught the hoarse thunder of their charge while I felt the very stone under me quiver with the shock—then, I must confess a feeling of sickening horror came over me; I started back involuntarily, and nothing on earth could have induced me to plant my foot on the crazy ladder which, a few moments ago, I had made up my mind to descend.

“ ‘But how grand, how magnificent, how sublime was the spectacle! The towering waves which like a stately row of hills came moving along the intense azure blue of the Indian Ocean—that graceful curve of the billow as it neared the pumice reefs which lie at the base of the mass of trachyte—then the thundering fall of this mighty crest toppling over, as it were, into a sea of seething milk in which every drop, every foam-speck glittered in the rays of the tropical sun—that finely divided spray which hung over the watery mass and wrapped it as in a veil of transparent silver-gauze—all this, my friends, formed a spectacle which can never be effaced from my memory but will dwell there engraven as on tables of stone. At times, when a wave of unusual height came rolling in, the entrance of the caves would be completely swallowed up and hidden and the water driven into the interior would continue its perpetual work of excavation. Then, for a few moments it seemed as if the holes had disappeared. But presently, when the wave flowed back again, the water, impelled by the tremendous force of the compressed air within, would rush forth like a horizontal fountain five or six hundred feet in length, spouting and hissing and blowing with a roar which was perfectly appalling, and forming whirls and high-flowing eddies in the retreating wave.

“ ‘No, no, no, I durst not touch that swinging ladder; but I have nevertheless made up my mind to penetrate by some other means into the interior of those mysterious cavities. The natives here tell me that when the south-east trade-wind is far from the south-coast of Java, on very calm days a flat-bottomed boat may enter the Goewah Temon, which is the name of one of the grots. The loerah of the dessa Ajo has promised me to keep a canoe in readiness for me, if I will give him notice beforehand; and, on the first favourable opportunity I mean to make the attempt. Meanwhile, however, I have had to satisfy myself with a description of this birdsnesting which I soon hope to witness in person, and this is what one of the chiefs has told me concerning it.

“ ‘From the mouth of the caves the Javanese have stretched a couple of cables along the interior wall. The lower of these rottang-cables serves as foot-hold, the upper is grasped in one hand, while with the other hand, the man engaged in the work picks the birds’ nests from the rock. When the hand cannot reach them the man detaches them by means of a long bamboo pole furnished with an iron hook, and as they fall he has to catch them in a small hand net. As you may suppose, the taking of these swallows’ nests is an extremely perilous undertaking. First to clamber down that ladder to an extreme depth along the perpendicular face of the rock and dangling over that boiling sea, then to penetrate into these holes into which the ocean thrusts its waves. In rough weather the work has to be stopped altogether in many of the caves; and, not unfrequently, it happens that the ropes are washed away and the poor fellows who trust to them are dashed to pieces or miserably drowned. You will ask then, perhaps, how can people be found to venture on so hazardous an undertaking? You know, of course, that no race on earth is more attached to its native soil than the Javanese. That characteristic is found in this part of the island also. There is perhaps no wilder and more ungrateful soil in this world than this region in the Karang Bollong mountains. Nothing, or next to nothing, can be made out of agriculture. The tiny rice-fields one meets with here and there on the mountain slopes, are not worth mentioning; and, as far as tradition reaches, the scanty population of this part of Java has always supported itself and does still support itself, by collecting these edible nests.

“ ‘Whether they fared better or worse before the Dutch government appropriated that source of income to itself, I have not been able to ascertain. But one thing is certain, that the pay these poor wretches receive from the Government is something worse than pitiful. I have now lying before me a statement drawn up by an official in this part of the country, from which I gather that, for every sack of 80 nests delivered into the Government stores, the man who collects them gets a sum of 15—let us put it down in words—of fifteen cents (about 3d.)!’ ”

“Aye but,” said Grashuis, “before we follow the grumblings of our Pole any further, it would be well to know what is the commercial value of those 80 nests.”

“As a merchant,” remarked Grenits, “I can at once supply you with the information you require. The Chinese are always ready to give five thousand guilders for a pikol of nests, and, since one hundred of them weigh about one kattie and the pikol contains one hundred katties, our Government receives four hundred guilders, while it sends the poor devil of a native about his business with 15 cents! By Heaven it is a crying shame!”

“But has not the Government other expenses to meet?” asked Grashuis.

“Allow me to continue,” said van Rheijn, “I promise you an answer to your question, August.”

“All right, drive ahead!”
