Next day I returned to the forest of evil report, which had now a new and even greater charm--the fascination of the unknown and the mysterious; still, the warning I had received made me distrustful and cautious at first, for I could not help thinking about it. When we consider how much of their life is passed in the woods, which become as familiar to them as the streets of our native town to us, it seems almost incredible that these savages have a superstitious fear of all forests, fearing them as much, even in the bright light of day, as a nervous child with memory filled with ghost-stories fears a dark room. But, like the child in the dark room, they fear the forest only when alone in it, and for this reason always hunt in couples or parties. What, then, prevented them from visiting this particular wood, which offered so tempting a harvest? The question troubled me not a little; at the same time I was ashamed of the feeling, and fought against it; and in the end I made my way to the same sequestered spot where I had rested so long on my previous visit.
In this place I witnessed a new thing and had a strange experience. Sitting on the ground in the shade of a large tree, I began to hear a confused noise as of a coming tempest of wind mixed with shrill calls and cries. Nearer and nearer it came, and at last a multitude of birds of many kinds, but mostly small, appeared in sight swarming through the trees, some running on the trunks and larger branches, others flitting through the foliage, and many keeping on the wing, now hovering and now darting this way or that. They were all busily searching for and pursuing the insects, moving on at the same time, and in a very few minutes they had finished examining the trees near me and were gone; but not satisfied with what I had witnessed, I jumped up and rushed after the flock to keep it in sight. All my caution and all recollection of what the Indians had said was now forgot, so great was my interest in this bird-army; but as they moved on without pause, they quickly left me behind, and presently my career was stopped by an impenetrable tangle of bushes, vines, and roots of large trees extending like huge cables along the ground. In the midst of this leafy labyrinth I sat down on a projecting root to cool my blood before attempting to make my way back to my former position. After that tempest of motion and confused noises the silence of the forest seemed very profound;but before I had been resting many moments it was broken by a low strain of exquisite bird-melody, wonderfully pure and expressive, unlike any musical sound I had ever heard before. It seemed to issue from a thick cluster of broad leaves of a creeper only a few yards from where I sat. With my eyes fixed on this green hiding-place I waited with suspended breath for its repetition, wondering whether any civilized being had ever listened to such a strain before. Surely not, I thought, else the fame of so divine a melody would long ago have been noised abroad. I thought of the rialejo, the celebrated organbird or flute-bird, and of the various ways in which hearers are affected by it. To some its warbling is like the sound of a beautiful mysterious instrument, while to others it seems like the singing of a blithe-hearted child with a highly melodious voice. I had often heard and listened with delight to the singing of the rialejo in the Guayana forests, but this song, or musical phrase, was utterly unlike it in character. It was pure, more expressive, softer--so low that at a distance of forty yards I could hardly have heard it. But its greatest charm was its resemblance to the human voice--a voice purified and brightened to something almost angelic.ne, then, my impatience as I sat there straining my sense, my deep disappointment when it was not repeated! I rose at length very reluctantly and slowly began making my way back;but when I had progressed about thirty yards, again the sweet voice sounded just behind me, and turning quickly, I stood still and waited. The same voice, but not the same song--not the same phrase; the notes were different, more varied and rapidly enunciated, as if the singer had been more excited. The blood rushed to my heart as I listened; my nerves tingled with a strange new delight, the rapture produced by such music heightened by a sense of mystery. Before many moments I heard it again, not rapid now, but a soft warbling, lower than at first, infinitely sweet and tender, sinking to lisping sounds that soon ceased to be audible; the whole having lasted as long as it would take me to repeat a sentence of a dozen words. This seemed the singer's farewell to me, for I waited and listened in vain to hear it repeated; and after getting back to the starting-point Isat for upwards of an hour, still hoping to hear it once more!
The weltering sun at length compelled me to quit the wood, but not before I had resolved to return the next morning and seek for the spot where I had met with so enchanting an experience. After crossing the sterile belt I have mentioned within the wood, and just before I came to the open outer edge where the stunted trees and bushes die away on the border of the savannah, what was my delight and astonishment at hearing the mysterious melody once more! It seemed to issue from a clump of bushes close by; but by this time I had come to the conclusion that there was a ventriloquism in this woodland voice which made it impossible for me to determine its exact direction. Of one thing I was, however, now quite convinced, and that was that the singer had been following me all the time. Again and again as I stood there listening it sounded, now so faint and apparently far off as to be scarcely audible; then all at once it would ring out bright and clear within a few yards of me, as if the shy little thing had suddenly grown bold; but, far or near, the vocalist remained invisible, and at length the tantalizing melody ceased altogether.
