"Yes, it's good if you don't get burned. I've been burned," and he thrust out an arm upon which appeared a cicatrice. Ab was interested. "Where did you get that?" he queried. "Far from here, far beyond the black swamp and the red hills that are farther still. It was when I was strong." "Tell me about it," said the youth. "There is a fire country," answered Old Mok, "away beyond the swamp and woods and the place of the big rocks. It is a wonderful place. The fire comes out of the ground in long sheets and it is always the same. The rain and the snow do not stop it. Do I not know? Have I not seen it? Did I not get this scar going too near the flame and stumbling and falling against a hot rock almost within it? There is too much fire sometimes!" The old man continued: "There are many places of fire. They are to the east and south. Some of the Shell People who have gone far down the river have seen them. But the one where I was burned is not so far away as they; it is up the river to the northwest." And Ab was interested and questioned Old Mok further about the strange region where flames came from the ground as bushes grow, and where snow or water did not make them disappear. He was destined, at a later day, to be very glad that he had learned the little that was told him. But to-night he was intent only on getting all the tales he could from the veteran while he was in the mood. "Tell about the Shell People," he cried, "and who they are and where they came from. They are different from us." "Yes, they are different from us," said Old Mok, "but there was a time, I have heard it told, when we were like them. The very old men say that their grandfathers told them that once there were only Shell People anywhere in this country, the people who lived along the shores and who never hunted nor went far away from the little islands, because they were afraid of the beasts in the forests. Sometimes they would venture into the wood to gather nuts and roots, but they lived mostly on the fish and clams. But there came a time when brave men were born among them who said they would have more of the forest things, and that they would no longer stay fearfully upon the little islands. So they came into the forest and the Cave Men began. And I think this story true." "I think it is true," Old Mok continued, "because the Shell People, you can see, must have lived very long where they are now. Up and down the creek where they live and along other creeks there lie banks of earth which are very long and reach far back. And this is not really earth, but is all made up of shells and bones and stone spearheads and the things which lie about a Shell Man's place. I know, for I have dug into these long banks myself and have seen that of which I tell. Long, very long, must the Shell People have lived along the creeks and shores to have made the banks of bones and shells so high."
