The book contains xiii + 418 pages, including a glossary and 

 an index, is printed on good paper and clear type, bound in cloth, 

 and the printers can be complimented as well as the authors. 



The book will be an excellent guide to the flora of the western 

 slopes of the Cascades, and, without doubt, will be greeted with 

 pleasure by all flower-lovers in the region and to anyone who has 

 the opportunity to visit that part of the Pacific slope. It is 

 technical enough to train the student for the use of more elaborate 

 systematic works, and not at all too technical to be used with 

 advantage in the high-schools. Many of the so-called "flower 

 books" written mostly by young ladies are too "popular" in 

 style to give the student any training in science, and usually so 

 inaccurate and erroneous in their statements that they are in 

 many respects more harmful than useful. The book is conserva- 

 tive enough in the better sense of the word but progressive enough 

 to keep up with the development of taxonomy in the last thirty 

 years. It does not contain any new freak notion concerning 

 limitation of species and nomenclature, as some books lately 

 published on western botany have, but is sane in its treatment. 

 While the reviewer's ideas dilTer in individual cases from the 

 treatment in the new work, the general impression he has received 

 from the book is most pleasing. The same can be said of two 

 other local floras of the Pacific coast, Abram's Flora of Los 

 Angeles County, California, and Hall's Flora of the Yosemite 

 Valley.
