They were human and yet not human. I should say that they were a little higher in the scale of evolution than Ahm, possibly occupying a place of evolution between that of the Neanderthal man and what is known as the Grimaldi race. Their features were distinctly negroid, though their skins were white. A considerable portion of both torso and limbs were covered with short hair, and their physical proportions were in many aspects apelike, though not so much so as were Ahm's. They carried themselves in a more erect position, although their arms were considerably longer than those of the Neanderthal man. As I watched them, I saw that they possessed a language, that they had knowledge of fire and that they carried besides the wooden club of Ahm, a thing which resembled a crude stone hatchet. Evidently they were very low in the scale of humanity, but they were a step upward from those I had previously seen in Caspak.
