The object of informal nature study is to put children directly in touch with the beautiful and wonderful things which are within their reach. Its lesson-book is everywhere, its time is every time, its spirit is wonder and delight. This is for the children. Those who teach it have to look beyond, and it is not so easy to teach as it is to learn. It cannot, properly speaking, be learned by teachers out of books, though books can do a great deal. But a long-used quiet habit of observation gives it life and the stored-up sweetness of years--"the old is better." The most charming books on nature study necessarily give a second-hand tone to the teaching. But the point of it all is knowledge at first-hand; yet, for children knowledge at first-hand is so limited that some one to refer to, and some one to guide them is a necessity, some one who will say at the right moment "look" and "listen," and who has looked and listened for years. Perhaps the requirement of knowledge at firsthand for children has sometimes been pushed a little too far, with a deadening effect, for the progress of such knowledge is very slow and laborious. How little we should know if we only admitted first-hand knowledge, but the stories of wonder from those who have seen urge us on to see for ourselves; and so we swing backwards and forwards, from the world outside to the books, to find out more, from the books to the world outside to see for ourselves. And a good teacher, who is an evergreen learner, goes backwards and forwards, too, sharing the work and heightening the delight. All the stages come in turn, over and over again, observation, experiment, inquiry from others whether orally or in books, and in this subject books abound more fascinating than fairy tales, and their latest charm is that they are laying aside the pose of a fairy tale and tell the simple truth.
