A third voice was indubitably that of a mechanical utterance-machine connected with one of the detached brains in the cylinders. There was as little doubt about that as about the buzzings; for the loud, metallic, lifeless voice of the previous evening, with its inflectionless, expressionless scraping and rattling, and its impersonal precision and deliberation, had been utterly unforgettable. For a time I did not pause to question whether the intelligence behind the scraping was the identical one which had formerly talked to me; but shortly afterward I reflected that any brain would emit vocal sounds of the same quality if linked to the same mechanical speech-producer, the only possible differences being in language, rhythm, speed and pronunciation. To complete the eldritch colloquy there were two actually human voices – one the crude speech of an unknown and evidently rustic man, and the other the suave Bostonian tones of my erstwhile guide Noyes.

As I tried to catch the words which the stoutly-fashioned floor so bafflingly intercepted, I was also conscious of a great deal of stirring and scratching and shuffling in the room below; so that I could not escape the impression that it was full of living beings – many more than the few whose speech I could single out. The exact nature of this stirring is extremely hard to describe, for very few good bases of comparison exist. Objects seemed now and then to move across the room like conscious entities, the sound of their footfalls having something about it like a loose, hard-surfaced clattering – as of the contact of ill-coordinated surfaces of horn or hard rubber. It was, to use a more concrete but less accurate comparison, as if people with loose, splintery wooden shoes were shambling and rattling about on the polished board floor. Of the nature and appearance of those responsible for the sounds, I did not care to speculate.

Before long I saw that it would be impossible to distinguish any connected discourse. Isolated words – including the names of Akeley and myself – now and then floated up, especially when uttered by the mechanical speech-producer; but their true significance was lost for want of continuous context. Today I refuse to form any definite deductions from them, and even their frightful effect on me was one of suggestion rather than of revelation. A terrible and abnormal conclave, I felt certain, was assembled below me, but for what shocking deliberations I could not tell. It was curious how this unquestioned sense of the malign and the blasphemous pervaded me despite Akeley’s assurances of the Outsiders’ friendliness.
