Here he lived happily for many years. He owned a share in the long- horned cattle. His men were the best hunters in the village, and the copper things he made were sought for by men who came long distances. Sometimes they brought him bars of copper. After a time some one brought tin, and two pieces fell into the fire one day, along with a copper knife, and all three were melted into one and cooled in a little hollow in the ashes after the fire was out. Umpl was astonished to find that the sharp edge of this would cut like flint, yet would not bend like copper; and he began to make regular knives and spearheads of such material, finding out a way of making clay moulds and pouring the melted metal into them to harden into the right shapes. Of course these were far more valuable than the copper tools and they were sold here and there among the tribes of other peoples, and often travelled far from where they were made. Other people began to find out how to make them, and made so many that, although they still used flint knives too, yet people nowadays when speaking of that long ago time often call it the Bronze Age, because tin and copper, when melted together in a certain way, make bronze. But the Iron Star's travels were not ended. SPARK III. HOW THE STAR WAS CARRIED ON THE WARPATH, AND WHAT CAME OF IT. Just why it seemed necessary for Umpl and his people to go to war with anybody may not be clear. They were living very happily in their village on the lake. Their cattle were fat; their fields of that curious grass through which Umpl had waded before he knew what it was good for were sure to harvest grain enough to make bread, and Sptz had found that grain-bread was as much better than acorn-bread as sponge cake is better than gingerbread; although both gingerbread and acorn- bread are good enough for any one, when one cannot get anything better.
