So enormous are the great carnivora of Caspak that they must feed perpetually to support their giant thews, and the result is that they will eat the meat of any other creature and will attack anything that comes within their ken, no matter how formidable the quarry. From later observation--I mention this as worthy the attention of paleontologists and naturalists--I came to the conclusion that such creatures as the cave-bear, the cave-lion and the saber-tooth tiger, as well as the larger carnivorous reptiles make, ordinarily, two kills a day--one in the morning and one after night. They immediately devour the entire carcass, after which they lie up and sleep for a few hours. Fortunately their numbers are comparatively few; otherwise there would be no other life within Caspak. It is their very voracity that keeps their numbers down to a point which permits other forms of life to persist, for even in the season of love the great males often turn upon their own mates and devour them, while both males and females occasionally devour their young. How the human and semihuman races have managed to survive during all the countless ages that these conditions must have existed here is quite beyond me. After breakfast Ajor and I set out once more upon our northward journey. We had gone but a little distance when we were attacked by a number of apelike creatures armed with clubs. They seemed a little higher in the scale than the Alus. Ajor told me they were Bo-lu, or clubmen. A revolver-shot killed one and scattered the others; but several times later during the day we were menaced by them, until we had left their country and entered that of the Sto-lu, or hatchet-men. These people were less hairy and more man-like; nor did they appear so anxious to destroy us. Rather they were curious, and followed us for some distance examining us most closely. They called out to us, and Ajor answered them; but her replies did not seem to satisfy them, for they gradually became threatening, and I think they were preparing to attack us when a small deer that had been hiding in some low brush suddenly broke cover and dashed across our front. We needed meat, for it was near one o'clock and I was getting hungry; so I drew my pistol and with a single shot dropped the creature in its tracks. The effect upon the Bo-lu was electrical. Immediately they abandoned all thoughts of war, and turning, scampered for the forest which fringed our path.
