THE AMERICAN BOTANIST 73 



and green algae under the divisions Myxophyceae (Cy- 

 anophyceae), Peridinieae, Bacillariae, and Chlorophyceae. 

 The bulk of the book is devoted to the last mentioned 

 group whose species are arranged under the divisions 

 Isokontae, Akontae, Stephanokontae, and Heterokontae. 

 The inclusion of the algae in all college and most high 

 school courses in botany renders some knowledge of this 

 group imperative on the part of both student and teacher, 

 and all will therefore be glad to have this authoritative 

 text which goes into the subject rather more fully than 

 other works of a similar nature. Issued after several years 

 of active study of the group by many observers, it contains 

 the latest views on many points at issue. In addition to 

 the strictly scientific account of structures and relation- 

 ships, the book has much of interest to the general reader. 

 There are over a thousand figures, many of them from 

 original drawings by the author. Mechanically the book 

 is well done, paper, presswork and binding being above 

 criticism. The book which is a large octavo of 475 pages 

 is issued by the Cambridge University Press, England, 

 which is represented on this side of the world by G. P. 

 Putnam's Sons, Xew York. The price is $6.25. 



Xow that this country is producing more than 125 

 million boxes of strawberries annually from no less than 

 1800 different varieties of the plant with a total value 

 greater than the crop of prunes, pears, or cherries, the 

 need for a book like S. \Y. Fletcher's "Strawberry Grow- 

 ing" is apparent. From this book we learn that there is no 

 special strawberry region to which growing is restricted, 

 as is the case with some other fruits. Strawberries may 

 be grown anywhere if there is moisture enough, but as a 

 matter of fact the bulk of the crop comes from the Prov- 

 ince of Ontario, the Atlantic seaboard south of Xew York, 

 the Gulf Coast, the Ozark region in Missouri and Arkansas,
