From some still lower chasm in earth's bowels were proceeding certain sounds, measured and definite, and like nothing I had ever heard before. That they were very ancient and distinctly ceremonial, I felt almost intuitively; and much reading in Egyptology led me to associate them with the flute, the sambuke, the sistrum, and the tympanum. In their rhythmic piping, droning, rattling, and beating, I felt an element of terror beyond all the known terrors of earth—a terror peculiarly dissociated from personal fear, and taking the form of a sori of objective pity for our planet, that it should hold within its depths such horrors as must lie behind these aegipanic cacophonies. The sounds increased in volume, and I felt that they were approaching. Then—and may all the gods of all pantheons unite to keep the like from my ears again—I began to hear, faintly and afar off, the morbid and millennial tramping of the marching things.
