The teacher should have an opera glass or a small field glass with which to make her own observations. It is obvious that the more glasses there are among the children, the better. It is advisable for the teacher to make short excursions with the children to the streets to assist them in answering these questions. These can be made at the close of school. As a preparation, have some crumbs or seeds scattered where the birds have been seen. Continue work with these questions until each one can give a reasonably accurate description of the appearance of the bird and of its movements. Have the older pupils write this. It will make a good language lesson. The next questions should have reference to the life and characteristics of the bird. What does it eat? Put out crumbs or scraps of meat and see if the bird will eat them. What sounds does the bird make? Does it sing? Imitate as many of its sounds as you can. Determine from its actions what its disposition is. For example--Is it courageous? Is it quarrelsome? Is it inclined to fight? Is it selfish? Frequently a single incident in a bird's life will furnish an answer to several of these questions. Two sparrows were seen attempting to take possession of the same straw. Each held firmly to his end of the straw. A regular tug of war ensued. They pulled one another about for some time on the top of an awning, and finally, becoming tired of this, they dropped the straw and furiously attacked each other. They fought with beak and claw, paying no attention to the spectators, and fell exhausted to the sidewalk, where they lay upon their backs until able to hop slowly away from each other. It was some little time before they recovered strength to fly in opposite directions, conquering and unconquered. Early in March advise the children to watch the direction of the sparrows' flight. They will discover that some of them are carrying straws or feathers or other material for nest building. Notice the position and style of these nests. Those built early in the season are always in protected places, under the eaves of houses or in holes in trees or in bird boxes. Some of those built later are in exposed places, clumsy affairs, but well thatched with straw, having an entrance on one side. This nest building may be watched during the entire season, for the English sparrow raises more broods than any other of our birds. The interpretation of the actions which indicate any of a bird's characteristics is a valuable part of the study on account of its exercise of the imagination and the reason. A plan similar to the foregoing should be followed with each bird that is studied. With almost all other birds the study will be far more interesting. The English sparrow may be considered as the A B C of birds in his appearance and in the kind of life he leads. He is therefore a good subject to begin with. But even he will be found to exhibit unexpected individuality.
