limits too many of his to "define," "describe," or the very 

 indefinite "discuss." Most high school teachers need some indi- 

 cation of the kind and amount of laboratory work expected by 

 the author; that has been one great advantage of the Bergen 

 text books. The last, Bergen and Caldwell's Practical Botany, 

 is surely just as readable and interesting as this, although it 

 retains the text-book style. Among the books which have a 

 better foundation for the title-page claims Bigelow's Applied 

 Biology might be mentioned ; their later Introduction to Biology 

 has a most original arrangement of the recognized high school 

 matter, and which is, nevertheless, logical. Dr. Coulter it would 

 seem is unfortunate in the arrangement of subject matter, 

 e. g., discussing photosynthesis on page 43, just forty-six pages 

 before he defines solutions, molecules, and compounds. 



The illustrations are often insufficiently labeled (as in those of 

 the root and stem, pp. 80-83, or in the flower diagrams on 291). 



While Dr. Coulter, no doubt, makes botany a live subject in 

 his own teaching, he has not, unfortunately, put into his book 

 the many things the many unprepared teachers need to help 

 them do their work.

Rock's The Indigenous Trees of the Hawaiian Islands * 



This handsome work, published by the aid of thirty-three 

 liberal patrons of botany, is a most useful and valuable presenta- 

 tion of the arborescent plants of the Hawaiian Islands. Tech- 

 nical descriptions of all species observed by the writer as trees, 

 even if usually occurring as shrubs, are given, together with the 

 native name, notes on uses of woods, fibers, leaves, fruits, oils 

 and other products, and the distribution of the species within 

 the islands and elsewhere. The illustrations are all photographs, 

 either of isolated trees or of twigs showing flowers or fruit, 

 sometimes both. 



The descriptive portion of the work is prefaced by detailed 

 accounts of the six botanical regions, (i) strand vegetation; (2)
