Yes, the wild things of the out-of-doors are so interesting that all over the world today thousands of men and women are studying them. And they are writing books and stories of the wonderful things they see and learn. You are now going to read some of these stories. Three Boy Scouts will tell you how it feels to be surrounded by lions at night. Mrs. Bradley will tell you about Pembe Kubwa, a wise and wicked elephant. Mr. Rutledge will explain why birds and animals need our help in this day of farms and cities. As you read some of these stories and observe the outdoor life around you, perhaps you will learn, too, that while some outdoor things should be protected, others must be destroyed.
