One summer evening I was sitting by the open window, reading a good science storybook. (79)I was so interested in the story I was reading that I did not notice that it was getting dark. When I realized it was too dark for me to read easily, I put the book down and got up to turn on the light. Just then I heard someone crying, "Help! Help!" it seemed to come from the trees at the other end of the yard. (80)I looked out but it was now too dark to see anything clearly. Almost immediately I heard the cry again. It sounded like a child, but I could not imagine what anybody could be doing in our backyard, unless one of the neighborhood children had climbed a tree and had not been able to get down.
I decided that I should go out and have a look in the yard, just in case someone was in trouble. I turned on the light and found for myself a flashlight and a baseball bat in the room. I thought they might be useful. Armed with these, I went out into the yard. Once again I heard the cry and this time there was no doubt that it came from the trees at the far end of the yard. "Who's there？" I called out as I walked across the yard towards the trees. But there was no answer. With the help of my flashlight, I searched all over that end of the yard, including the branches of the tree. There was no sign of anybody or anything. I came to the conclusion that my imagination was playing tricks on me, probably because of the story I was reading about strange creatures on another planet.
Feeling rather foolish about hunting around in my own backyard with a baseball bat, I went back into the house and put the bat and the flashlight away. I had just sat down to read my book again when I was frightened by the cry of "Help! Help!" from right behind me. I dropped my book and jumped up. There, sitting on the table was a large green and red bird. It was my neighbor's parrot(鹦鹉)!While I was out in the yard, the parrot must have seen the light in the living room and come in through the open window.

Not only did the Indians appear to lack a formal system of authority, but they also deeply hated any efforts to control their actions. All members of the tribes knew what was required of them by lifelong familiarity with the tasks of the area. These tasks tended to be simple, since the Indian's rate of social change was slow. Thus, although subgroups such as soldiers had recognized leaders, no real authority was required. Rather than giving direct orders (which were considered rough), members of the tribes would arouse others to action by examples.
It would be difficult, if not impossible, to carry out such a system in our own society. Most of us have grown up under one authority or another for as long as we can remember. Our parents, our teachers, our bosses, our government all have the recognized right under certain conditions to tell us what to do. The authority is so much a part of our culture that it is hard for us to imagine a workable society without it. We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale.
Of course, the major reason why the Indian system would not be suitable for us is that our society is too large. The number of tasks that various members of our society have to perform. often under tight time and resource limitations could not be treated by the Indian system. In modern societies, the formal authority system is necessary to achieve any social objectives.
