Q: Article: Each Indian was supposed to keep his birth name until he was old enough to earn one for himself.But his playmates would always give him a name of their own.No matter what his parents called him, his childhood friends would use the name they had chosen.Often it was not pleasing, such as Bow Legs or Bad Boy.But sometimes a name fit so well that the youngster found it difficult to shake it off.If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life. The Indian earned his real name when he was old enough for his first fight against the enemy.His life name depended on how he acted during this first battle.When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief.If he had done well, he would get a good name.Otherwise he might be called Crazy Wolf or Man-Afraid-Of-a-Horse.So an Indian's name told his record or described the kind of man he was. A man was given many chances to improve his name, however.If in a later battle he was brave in fighting against the enemy, he was given a better name.Some of our great fighters had as many as twelve names--all good and each better than the last. An Indian's names belonged to him for the rest of his life.No one else could use them.Even he himself could not give them away because names were assigned by the tribe, not the family.So no man could pass on his name unless the chief and the tribe asked him to do so. Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed.I know of only three of four times when this happened.It is the rarest honor for a person--the honor of assuming his father's name.

Q: Article: Bears and humans often meet in National Parks. Although campers and hikers are warned not to feed the bears, many people ignore these warnings and feed the beasts anyway. When bears are used to people's food, problems soon arise. Bears like to eat a large variety of things, both meat and vegetable. Without human assistance, bears live nicely on roots, twigs, leaves of trees, insects and small animals. With people around, the bears' tastes quickly expand to include sandwiches, hot dogs, hamburgers, and anything else they can temp humans into giving up. Bears often develop clever strategies for getting people to let go their food supplies. More often than not, an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods, grab the pack and quickly disappear into the underbrush with it. Hanging the pack on a tree branch won't help. Bears have been known to climb up, jump off, and catch the pack on the way down. One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole. Many bears threaten people into giving up their supplies. Although a bear is unlikely to attack a person and would probably run away if screamed at, few people are willing to do so. Most people drop the pack and run the other way. This, of course, delights the bear. In some places, the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears. Although the bears were unable to open these containers, the effort was less than successful. Most campers, unable to tell the metal drums from rubbish cans, never used them for the intended purpose.
