This book is intended for the use of students in secondary schools. The word "practical" in the title has been chosen since an effort has been made to present those facts and theories about animals which will have the most practical bearing upon the daily life of the student. It refers not alone to the economic side of the subject but also to the elements that are of greatest intellectual value.
