"The purpose of this book is to acquaint the reader with the larger groups-orders, families, and divisions of the latter, so that typical representatives may be recognized and their habits understood.Instead of the word mammal, the word animal has been used throughout as having a better defined meaning to the average child. A conscientious effort to avoid technical terms and descriptions has been made that there may be nothing to confuse the young mind. Clarity and simplicity have been the objects kept constantly in view.At the same time the utmost care to be accurate in the smallest details has been exercised. To this end the works of leading authorities on American mammals have been carefully consulted and compared. No statements which are not confirmed by two or more naturalists of recognized standinghave been made." The Author
