whether the change was real or only imagined I know not, but the silence every minute grew more profound and the gloom deeper. Imaginary terrors began to assail me. Ancient fables of men allured by beautiful forms and melodious voices to destruction all at once acquired a fearful significance. I recalled some of the Indian beliefs, especially that of the mis-shapen, man-devouring monster who is said to beguile his victims into the dark forest by mimicking the human voice--the voice sometimes of a woman in distress--or by singing some strange and beautiful melody. I grew almost afraid to look round lest I should catch sight of him stealing towards me on his huge feet with toes pointing backwards, his mouth snarling horribly to display his great green fangs. It was distressing to have such fancies in this wild, solitary spot--hateful to feel their power over me when I knew that they were nothing but fancies and creations of the savage mind. But if these supernatural beings had no existence, there were other monsters, only too real, in these woods which it would be dreadful to encounter alone and unarmed, since against such adversaries a revolver would be as ineffectual as a popgun. Some huge camoodi, able to crush my bones like brittle twigs in its constricting coils, might lurk in these shadows, and approach me stealthily, unseen in its dark colour on the dark ground. Or some jaguar or black tiger might steal towards me, masked by a bush or tree-trunk, to spring upon me unawares. Or, worse still, this way might suddenly come a pack of those swift-footed, unspeakably terrible hunting-leopards, from which every living thing in the forest flies with shrieks of consternation or else falls paralysed in their path to be instantly torn to pieces and devoured. A slight rustling sound in the foliage above me made me start and cast up my eyes. High up, where a pale gleam of tempered sunlight fell through the leaves, a grotesque human-like face, black as ebony and adorned with a great red beard, appeared staring down upon me. In another moment it was gone. It was only a large araguato, or howling monkey, but I was so unnerved that I could not get rid of the idea that it was something more than a monkey. Once more I moved, and again, the instant I moved my foot, clear, and keen, and imperative, sounded the voice! It was no longer possible to doubt its meaning. It commanded me to stand still--to wait--to watch--to listen! Had it cried "Listen! Do not move!" I could not have understood it better. Trying as the suspense was, I now felt powerless to escape. Something very terrible, I felt convinced, was about to happen, either to destroy or to release me from the spell that held me.
