The Plant World. 



book is designed to meet the needs of teachers especially in 

 secondary schools in the state of New York. The treatment is 

 concise — although sometimes too concise where it is attempted 

 to deal with too many subjects in small compass — and the dis- 

 cussion clear, so that the book will be a good one for the be- 

 ginner. An important part is that dealing with plant geography, 

 which in the main is good, though in our opinion some of the 

 space given to special conditions and exceptional phenomena 

 might better have been spent in a fuller treatment of more 

 general features. A few slight inaccuracies may be noted, but 

 the composition of the book and the number and quality of 

 the illustrations seem to justify the prediction that it will be 

 widelv used.
