animal on Mars, and owing to its intelligence, loyalty, and ferocity is used in hunting, in war, and as the protector of the Martian man. I quickly saw that I would have difficulty in escaping the fangs of the beast on a straightaway course, and so I met his charge by doubling in my tracks and leaping over him as he was almost upon me. This maneuver gave me a considerable advantage, and I was able to reach the city quite a bit ahead of him, and as he came tearing after me I jumped for a window about thirty feet from the ground in the face of one of the buildings overlooking the valley. Grasping the sill I pulled myself up to a sitting posture without looking into the building, and gazed down at the baffled animal beneath me. My exultation was short-lived, however, for scarcely had I gained a secure seat upon the sill than a huge hand grasped me by the neck from behind and dragged me violently into the room. Here I was thrown upon my back, and beheld standing over me a colossal ape-like creature, white and hairless except for an enormous shock of bristly hair upon its head. CHAPTER VI A FIGHT THAT WON FRIENDS The thing, which more nearly resembled our earthly men than it did the Martians I had seen, held me pinioned to the ground with one huge foot, while it jabbered and gesticulated at some answering creature behind me. This other, which was evidently its mate, soon came toward us, bearing a mighty stone cudgel with which it evidently intended to brain me. The creatures were about ten or fifteen feet tall, standing erect, and had, like the green Martians, an intermediary set of arms or legs, midway between their upper and lower limbs. Their eyes were close together and non-protruding; their ears were high set, but more laterally located than those of the Martians, while their snouts and teeth were strikingly like those of our African gorilla. Altogether they were not unlovely when viewed in comparison with the green Martians. The cudgel was swinging in the arc which ended upon my upturned face when a bolt of myriad-legged horror hurled itself through the doorway full upon the breast of my executioner. With a shriek of fear the ape which held me leaped through the open window, but its mate closed in a terrific death struggle with my preserver, which was nothing less than my faithful watch-thing; I cannot bring myself to call so hideous a creature a dog.
