To study a nest is to make an acquaintance. However familiar the bird, unless the student has watched its ways during the only domestic period of its life,-nesting time,-he has still something to learn. In fact, he has almost everything to learn, for into those few weeks is crowded a whole lifetime of emotions and experiences which fully bring out the individuality of the bird. Family life is a test of character, no less in the nest than in the house. Moreover, to a devotee of the science that some one has aptly called Ornithography, nothing is so attractive. What hopes it holds out! Who can guess what mysteries shall be disclosed, what interesting episodes of life shall be seen about that charmed spot?
