When Dr. S. P. Langley, Secretary of the Smithsonian Institution, established the Children's Room in that great museum, he took for his motto, "Knowledge begins in wonder," and he put into this room a selection of specimens especially intended to excite interest in the young mind. The biggest bird and the littlest were placed side by side; curious eggs, nests, and insects-not many in number, but temptingly displayed-were ranged about to attract attention and to awake the desire to know more. It was the same Dr. Langley who had once declared that his chief interests in life were children and fairy stories, and it is in the little Washington room that we seem to find the thought embodied, for the children are there, and the fairy stories of nature are suggested on every hand. We are delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. Our philosophy has been guided by a desire to provide the reader with a book that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic work, and that for you it becomes an enriching experience.
