have reduced the repulsion on either side, until the two races would have flowed together to form one hybrid people, but long before that time the Æsir rose and departed, vanishing into the mysterious hazes of the haunted south. But before that exodus there came to pass the horror of the Worm.
I hunted with Grom and he led me into brooding, uninhabited valleys and up into silence-haunted hills where no men had set foot before us. But there was one valley, off in the mazes of the south-west, into which he would not go. Stumps of shattered columns, relics of a forgotten civilization, stood among the trees on the valley floor. Grom showed them to me, as we stood on the cliffs that flanked the mysterious vale, but he would not go down into it, and he dissuaded me when I would have gone alone. He would not speak plainly of the danger that lurked there, but it was greater than that of serpent or tiger, or the trumpeting elephants which occasionally wandered up in devastating droves from the south.
Of all beasts, Grom told me in the gutturals of his tongue, the Picts feared only Satha, the great snake, and they shunned the jungle where he lived. But there was another thing they feared, and it was connected in some manner with the Valley of Broken Stones, as the Picts called the crumbling pillars. Long ago, when his ancestors had first come into the country, they had dared that grim vale, and a whole clan of them had perished, suddenly, horribly and unexplainably. At least Grom did not explain. The horror had come up out of the earth, somehow, and it was not good to talk of it, since it was believed that It might be summoned by speaking of It—whatever It was.
But Grom was ready to hunt with me anywhere else; for he was the greatest hunter among the Picts, and many and fearful were our adventures. Once I killed, with the iron sword I had forged with my own hands, that most terrible of all beasts—old sabre-tooth, which men today call a tiger because he was more like a tiger than anything else. In reality he was almost as much like a bear in build, save for his unmistakably feline head. Sabre-tooth was massive-limbed, with a low-hung, great, heavy body, and he vanished from the earth because he was too terrible a fighter, even for that grim age. As his muscles and ferocity grew, his brain dwindled until at last even the instinct of self-preservation vanished. Nature, who maintains her balance in such things, destroyed him because, had his super-fighting powers been allied with an intelligent brain, he would have destroyed all other forms of life on earth. He was a freak on the road of evolution organic development gone mad and run to fangs and talons, to slaughter and destruction.
I killed sabre-tooth in a battle that would make a saga in itself, and for months afterwards I lay semi-delirious with ghastly wounds that made the toughest warriors shake their heads. The Picts said that never before had a man killed a sabre-tooth single-handed. Yet I recovered, to the wonder of all.
While I lay at the doors of death there was a secession from the tribe. It was a peaceful secession, such as continually occurred and contributed greatly to the peopling of the world by yellow-haired tribes. Forty-five of the young men took themselves mates simultaneously and wandered off to found a clan of their own. There was no revolt; it was a racial custom which bore fruit in all the later ages, when tribes sprung from the same roots met, after centuries of separation, and cut one another's throats with joyous abandon. The tendency of the Aryan and
