The Narrative of Arthur Gordon Pym, by Edgar Allan Poe .. Chapter 10
As our first loud yell of terror broke forth, it was replied to by something, from near the bowsprit of the stranger, so closely resembling the scream of a human voice that the nicest ear might have been startled and deceived.
At this instant another sudden yaw brought the region of the forecastle for a moment into view, and we beheld at once the origin of the sound. We saw the tall stout figure still leaning on the bulwark, and still nodding his head to and fro, but his face was now turned from us so that we could not behold it. His arms were extended over the rail, and the palms of his hands fell outward. His knees were lodged upon a stout rope, tightly stretched, and reaching from the heel of the bowsprit to a cathead.
