The women they had brought with them had children, and these children grew up and had more children, and before very long there were many hundred people in the tribe, and their stone huts dotted the cliffs as far as the eye could see. When they found there was not room enough behind the first wall for the growing village, they built another and longer wall, further back from the sea, for they were always afraid of being attacked, on account of the way their former village had been destroyed. Only the very oldest men remembered this now, but they told the story to the younger men, around the fires at night, and when these grew old, they told it to their children and grandchildren, so that it became a legend in the tribe that they had come from another country, where enemies lived who might attack them. A watchman stood day and night on the cliffs, looking out over the sea, ready to light signal fires, in case he saw boats coming toward them from across the water. The island people found plenty of flint, out of which to make weapons and tools for working wood, and they were very skilful fishermen, and also great hunters with the bow and arrow. As they made hunting trips far back into the country, they found many different kinds of wood for making bows and small canoes, but no reeds were to be found, so they forgot the art of making basket work. Neither did they find any clay, for a long time, and when the few bowls and jars they had brought with them were broken, they made drinking cups of the horns of animals, or of wood. They still used smoked meat and fish, but they knew nothing about planting and growing grains to make bread.
