But, before going any farther, you may like to know that these settlers were all of the polyp family: fathers and mothers, brothers and sisters, uncles and aunts,--all were polyps. And this is the way their families increased: after the first comers were fairly settled, and pretty thoroughly turned to stone, little buds, looking somewhat like the smallest leaf-buds of the spring-time, began to grow out of their edges. These were their children, at least one kind of their children; for they had yet another kind also, coming from eggs, and floating off in the water like the first settlers. These latter we might call the free children or wanderers, while the former could be named the fixed children. But even the wanderers come back after a short time, and settle beside their parents, as you remember the one who met the star- fish was about to do. It was not very easy for you or me to think back so many thousand years to the very beginning of Coraltown, nor is it less difficult to realize how many, many years were passing while the little town grew, even as far as I have told you. The old great-grandfathers and great-grandmothers had died, but they left their stone bodies still standing, as a support and assistance to their descendants who had built above them; and the walls had risen, not like walls of common stone or brick, but all alive and busy building themselves, day after day, and year after year, until now, at the time of the star-fish's visit, the topmost towers could sometimes catch a gleam of sunlight when the tide was low; and when storms rolled the great waves that way, they would dash against the little castles, breaking themselves into snowy spray, and crumbling away at the same time the tiny walls that had been the polyps' work of years. Do you think that was too bad, and quite discouraging to the workers. It does seem so; but you will see how the good God, who is their loving Father just the same as he is ours, had a grand purpose in letting the waves break down their houses, just as he always does in all the disappointments he sends to us. Wait till you finish the story, and tell me if you don't think so. And now let us see what the star-fish thought of the little town and its inhabitants. "Ah, these are your houses!" he said. "Why don't you come out of them, and travel about to see the world?"--"These are not our houses, but ourselves," answered the polyps; "we can't come out, and we don't want to. We are here to build, and building is all we care to do; as for seeing the world, that is all very well for those who have eyes, but we have none."
