Next he rang a soundless bell, and there entered one of the strangest creatures which Cabot had ever seen. In general appearance it bore out the same relation to a Cupian as does a small gorilla to a human being on earth. Its head was prognathous and set deep on its shoulders. Its skin was hairless, except on the top of its head, and was the color of bluish slate. Its arms were long and gangling. It stood with a stoop and walked with a shuffle. Like the Cupians, it was earless, and had antennae, rudimentary wings, and six digits on each hand and foot. In the past Cabot had occasionally heard of the legendary blue apes which were sometimes said to be seen emerging from caves in the Okarze Mountains, but never before had he seen one. Furthermore, the presence and general appearance of this beast afforded a rational explanation of the manner of Cabot’s rescue from two aquatic boa-constrictors on the ledge above the river in the subterranean darkness, and of his presence here. His rescuer had had four hands; so had this blue ape. In the manuscript, which Myles Cabot shot from Venus to the earth in a streamline projectile, and which was published to mankind under the title of “The Radio Man,” it was stated that the Cupians had no basis for any Darwinian theory; but now Myles began to doubt that statement of his. Perhaps this was the true scientific basis of the legend of the subterranean origin of mankind. Perhaps the Cupians were descended from the blue apes of the Caves of Kar. This particular ape appeared to be a slave or servant of the old man, for at an inaudible command of the latter he brought a basin of warm water, with which the old man tenderly bathed his guest. Then, still wondering where he was, and why, Cabot dropped off to sleep again. When he reawoke, the old man was sitting in the room, and with him was a younger man, of the same general appearance and garb. The older handed over the following message: “Myles Cabot, this is Nan-nan, one of our electricians. He is at your service.” At once Cabot caught the drift of these remarks, and wrote back: “Bring me my apparatus, and let us try to repair it.” His two hosts glanced significantly at each other, and Myles began to fear that his radio set had been lost beneath the waves of the river Kar. But no, for an ape slave came bringing it, together with a bench and tools which they placed beside the couch. Then the electrician and Myles set to work. It took a long time, several sangths in fact, for the earth man was very weak, and all conversation had to be carried on in writing. * * * * *
