He used a thin sharp piece of flint with a wooden handle to bore the hole, twirling it rapidly between the palms of his hands, and at the same time pressing down upon it as hard as he could. It was a very hot day. The soft, moss-like fibres which covered the outside of the nut were dry as tinder. As the drill cut slowly into the hard shell, Ka-Ma saw, to his surprise, a tiny wisp of smoke curl up from the hole. Its smell told him it was the same smoke he had smelt so often in the Fire Cave at home. Harder and harder he pressed the drill down, faster and faster he twirled it, and then, suddenly, the smoke burst into a tiny flame, which licked up the dry fibres about the edge of the hole and was gone. Filled with wonder, he tried again and again, and each time the little flame appeared, and went out. At last, after he had thought for a long while, he picked a bunch of the dry moss-like fibres from the shell, and giving it to one of his sons, told him to hold the fibres in the flame the next time it appeared. He also gathered beside him a heap of dry leaves and grass. When the boy put the fibres into the flame, they blazed up at once, and burnt his hand so that he dropped them with a cry of pain, but Ka-Ma took the blazing bit and placed it among the dry leaves and grass, and in a moment he had a fire. Tula, who had been watching him, quickly brought reeds, and bits of wood, and soon a hot fire was roaring in front of the hut. The children gathered about, astonished and a little afraid, but Ka-Ma and his wife were filled with joy. He did not know why the fire had come, for he did not understand that friction, caused by rubbing two objects together, makes heat, but he was very grateful, for he had now found a way to make fire whenever he wanted it. For this reason, it was not necessary for him or his family to keep the fire going night and day, and thus the new tribe no longer thought of the fire as sacred. They did not worship it, the way the valley people did. Being able to make it whenever they wanted to, it no longer seemed to them so wonderful, nor were they afraid of losing it. Instead of worshipping fire, they began to worship the Sun, and the Sea. That night, Ka-Ma cooked some fish over the hot coals, and he and all his family had a feast. Later on he showed his children how to preserve fish by smoking them, the way his people had done in the valley. Then he began to search through the back country for clay. At last he found some, and it was not long before the new tribe was using pottery bowls and jars, just as they were used by the tribe in the valley. One of Ka-Ma's sons, named Ran, was a great fisherman. No one could spear fish so well as he. In the ocean, of course, he could not reach them, for the water was far too deep, and the surf too strong, but he waded in the shallow spots along the river banks, and when he saw a fish lying in the mud, he would bring his spear down as quick as a flash, and rarely ever missed.
