Do you like to dig for hidden treasure? Have you ever found Indian arrowheads or Indian pottery? I knew a boy who was digging a cave in a sandy place, and he found an Indian grave. With his own hands he uncovered the bones and skull of some brave warrior. That brown skull was more precious to him than a mint of money. Another boy I knew was making a cave of his own. Suddenly he dug into an older one made years before. He crawled into it with a leaping heart and began to explore. He found an old carpet and a bit.
