The world of out-of-doors is full of secrets. And they are so interesting that quite a lot of people are busy studying them. All around us are birds, animals, trees and flowers. The facts about how they  1  and grow are as interesting as anything could be. Do you know that one of the greatest presidents of the USA spent hours and hours  2  birds? A businessman who lives near New York city became so  3  in insects that he began to collect them. He now has more than one thousand different kinds carefully  4  in glass boxes. Come then with me, and I will help you find some of nature’s secrets. Let us go  5  through the woods and fields. Here we shall find how a rabbit tells the other rabbits that there is danger. We shall  6  a mother bear and her young ones as they look for  7  and get ready for winter sleep. We shall watch bees dancing in the air to let other bees know  8  they can find food. I will show you many other interesting things, but the thing that I can  9  you is to keep your eyes and ears  10  when you go out of doors. Nature tells her secrets only to people who look and listen carefully.
