4 PREFACE- 



technical descriptions, I hope that the indicated pronounciation of 

 the names, and the interest of the subject, may render it available, 

 not only as a school-library reference-book, but as a book for 

 supplemental reading in the more advanced classes of our schools. 



It is most desirable that the children and youth of our Western 

 Slope should become interested in , and intelligently acquainted with , 

 the rich and varied forms of life which are resting or moving all 

 around them. 



If this book shall awaken or increase an interest in the humble 

 but beautiful creatures of which it treats, my purpose will be accom- 

 plished. 



It remains for me to thank the many kind friends who have 

 assisted me ; particularly Mrs. C. T. Mills, whose generous addi- 

 tions to the college cabinet have been of the greatest assistance; 

 and Miss Laura M. Mellen, whose skill in illustrating the work speaks 

 for itself, but whose patience and painstaking are known to but few. 

 I also wish to thank those who have kindly given me valuable 

 specimens and information, and to commend our united labors to 

 all lovers of nature. J. K.
