discovered what seemed might prove a feasible pass we moved our belongings to a new hut farther up. It was hard work—cold, bitter, cruel work. Not a step did we take in advance but the grim reaper strode silently in our tracks. There were the great cave bears in the timber, and gaunt, lean wolves—huge creatures twice the size of our Canadian timber-wolves. Farther up we were assailed by enormous white bears—hungry, devilish fellows, who came roaring across the rough glacier tops at the first glimpse of us, or stalked us stealthily by scent when they had not yet seen us. It is one of the peculiarities of life within Pellucidar that man is more often the hunted than the hunter. Myriad are the huge-bellied carnivora of this primitive world. Never, from birth to death, are those great bellies sufficiently filled, so always are their mighty owners prowling about in search of meat. Terribly armed for battle as they are, man presents to them in his primal state an easy prey, slow of foot, puny of strength, ill-equipped by nature with natural weapons of defense. The bears looked upon us as easy meat. Only our heavy rifles saved us from prompt extinction. Poor Perry never was a raging lion at heart, and I am convinced that the terrors of that awful period must have caused him poignant mental anguish. When we were abroad pushing our trail farther and farther toward the distant break which, we assumed, marked a feasible way across the range, we never knew at what second some great engine of clawed and fanged destruction might rush upon us from behind, or lie in wait for us beyond an ice-hummock or a jutting shoulder of the craggy steeps. The roar of our rifles was constantly shattering the world-old silence of stupendous canons upon which the eye of man had never before gazed. And when in the comparative safety of our hut we lay down to sleep the great beasts roared and fought without the walls, clawed and battered at the door, or rushed their colossal frames headlong against the hut’s sides until it rocked and trembled to the impact. Yes, it was a gay life. Perry had got to taking stock of our ammunition each time we returned to the hut. It became something of an obsession with him. He’d count our cartridges one by one and then try to figure how long it would be before the last was expended and we
