Chicago, Ill._# #Nature Study Publishing Company.# The Nature Study Publishing Company is a corporation of educators and business men organized to furnish correct reproductions of the colors and forms of nature to families, schools, and scientists. Having secured the services of artists who have succeeded in photographing and reproducing objects in their natural colors, by a process whose principles are well known but in which many of the details are held secret, we obtained a charter from the Secretary of State in November, 1896, and began at once the preparation of photographic color plates for a series of pictures of birds. The first product was the January number of "BIRDS," a monthly magazine, containing ten plates with descriptions in popular language, avoiding as far as possible scientific and technical terms. Knowing the interest children have in our work, we have included in each number a few pages of easy text pertaining to the illustrations. These are usually set facing the plates to heighten the pleasure of the little folks as they read. Casually noticed, the magazine may appear to be a children's publication because of the placing of this juvenile text. But such is not the case. Those scientists who cherish with delight the famous handiwork of Audubon are no less enthusiastic over these beautiful pictures which are painted by the delicate and scientifically accurate fingers of Light itself. These reproductions are true. There is no imagination in them nor conventionalism. In the presence of their absolute truth any written description or work of human hands shrinks into insignificance. The scientific value of these photographs can not be estimated.
