“They penetrated beneath our garments, these swollen, lustful, unclean things; and it was whilst we staggered on through the swamp in agony of mind and body that we saw the light of many torches amid the trees ahead of us, and in their smoky glare witnessed the flight of hundreds of bats. The moonlight creeping dimly through the mist, and the torchlight--how do you say?--enflaming the vegetation, created a scene like that of Inferno, in which naked figures danced wildly, uttering animal cries. “Above the shrieking and howling, which rose and fell in a sort of unholy chorus, I heard one long, wailing sound, repeated and repeated. It was an African word. But I knew its meaning. “It was ‘_Bat Wing_!’ “My doubts were dispersed. This was a meeting-place of Devil-worshippers, or devotees of the cult of Voodoo! One man only could I see clearly so as to remember him, a big negro employed upon one of my estates. He seemed to be a sort of high priest or president of the orgies. Attached to his arms were giant imitations of bat wings which he moved grotesquely as if in flight. There were many women in the throng, which numbered fully I should think a hundred people. But the final collapse of my brave, unhappy Valera at this point brought home to me the nature of the peril in which I stood. “He lay at my feet, moving convulsively, and sinking ever deeper in the swamp, red leeches moving slowly, slowly over his fast-disappearing body.” Colonel Menendez paused in his appalling narrative and wiped his moist forehead with a silk handkerchief.

He suddenly commenced again: “My next recollection is of awakening in my own bed at the hacienda. I had staggered back as far as the veranda, in raving delirium, and in the grip of a strange fever which prostrated me for many months, and which defied the knowledge of all the specialists who could be procured from Cuba and the United States. My survival was due to an iron constitution; but I have never been the same man. I was ordered to leave the West Indies directly it became possible for me to be moved. I arranged my affairs accordingly, and did not return for many years. “Finally, however, I again took up my residence in Cuba, and for a time all went well, and might have continued to do so, but for the following incident. One night, being troubled by insomnia--sleeplessness--and the heat, I walked out on to the balcony in front of my bedroom window. As I did so, a figure which had been--you say lurking?--somewhere under the veranda ran swiftly off; but not so swiftly that I failed to obtain a glimpse of the uplifted face. “It was the big negro! Although many years had elapsed since I had seen him wearing the bat wings at those unholy rites, I knew him instantly.
