By sketches of insect, bird and plant life, Dr. Hancock has endeavored to illustrate, in its philosophic aspects, the doctrine of the organic evolution which has brought them to their present form, and also to throw some light on their present ecologic conditions. His sketches and studies are based on personal observation and are presented with a rare combination of literary charm and simplicity with sound scientific information, Dr. Hancock's frank interest and joy in his subject is infectious, and makes the book one which may be read with entertainment and profit. The book is profusely illustrated with photographs and sketches by the author.
