This book is absolutely indispensable to the entomologist who is also a 

 naturalist (sens, st.) who is interested in the relations of living things (Biota). 

 We will never comprehend the "unknown factors" of evolution, till we study 

 and understand the relations and interrelations of all the participants. 



The spirit in which the book was written is to be highly commended, as 

 shown in the dedication, quotations, preface and the body of the book. It is 

 the spirit of the naturalist (including in the term, the systematic student). 

 "The author, therefore cherishes the hope that these pages may be an inspira- 

 tion to some who have opportunity to take up special studies of our trees for 

 the sake of the intellectual pleasure and cultivation to be derived from such an 

 avocation." If the person who should read this book thoughtfully and "is not 

 stirred by the lure of the unknown," he is not "really and truly alive." 



On pages 13-49 are taken up twenty-four subjects connected with the study 

 of trees, which are very suggestive and stimulating. The Forest Provinces, each 

 treated very fully, should be studied by students of zoogeography, and those 

 preparing lists of species found in certain regions. Other suggestive and inter- 

 esting sections are : Arboreal Islands, The "Klamath Mountains,' A Histor- 

 ical Sketch of Sequoia, Local Tree Distribution and the Indian Tribes, and 

 Exploration ; Far Afield and Locally. From page 50, with a key to the fami- 

 lies, the various trees are described, with full distribution and bionomic notes 

 on each. It is a book which the naturalist should study in the laboratory and 

 take with him on his field excursions.
