It had been a curious discovery and one unlikely to have been made by other than this Hammer, friend and hut-mate of mine, and the shrewdest and most thinking man among us. He, who was ever alert to discover the reason of what was unusual, was attracted one day by the appearance of a particular boulder in the valley. It was different from the others in that it had upon it many outstanding points and bulges, as if the stone were harder in those spots and had yielded less to the chippings of the cold, heat and storms or whatever might make it grow smaller with time. He picked a small rock from the ground and struck a heavy blow upon one slender projection, longer than his hand, thinking to break it off, but it did not break; it only bent instead. Then, indeed, was the curiosity of Hammer aroused mightily. He would have that strange projection! Fiercely and strenuously he pounded upon it, and very wearily, at last, for he had set himself a serious task, though he finally succeeded in loosening the prong from the rock after long battering of it back and forth. He held in his hand something well worthy of his study. Hammer brought to our hut the red piece, which surely was not of the rock itself, and much we considered of what it might be and of what use it could be made to us. That last thought took but little time. Hammer decided it: “It will not break,” he said; “it will only bend, and that not easily, yet it may be hammered into many shapes. Such hammering it shall have. I will make a spear-head such as men have never seen!” He took the fragment of metal and one of the heaviest of our stone hammers and went with them to the hard flat boulder in the ravine and there began his pounding. All that afternoon came to our ears in the village the sound of the hammering at the rock. I did not go there, for I had other things to do out in the lower hills where I had seen a group of little deer, and where I thought I might get a chance at one as they came from the wood at sundown. I got none, and darkness had come when I reached our hut again and found Hammer by the fire, whereon he had roasted meat, which tasted good to both of us. I asked concerning his labour, and he showed me the piece of copper.
