This should be good property, over a long period -- and an essential item for libraries and school libraries. With all the second rate material on snakes, with the excellent biographical and anecdotal material, there seems to be little factual material covering a wide field. This book, by one of our best known scientists in this field, a man who has worked with Ditmars and Beebe and Andrews, who is connected with the American Museum and who is doing research work in his own right. The book not only gives a broad range of information about reptiles, but succeeds in destroying some legends and putting facts in their place. Contains an appendix with key for identification of the snakes of the United States and Canada. A book which could have an adult sale as there is no writing down to younger readers.
