World Book Company offers Science of Plant 

 Life for high school use. The book em- 

 bodies a response to the attractiveness of 

 plant life, a steadfast scientific spirit that 

 yields neither to sentiment nor to utility, 

 and an appreciation of the fact that the fun- 

 damental reason for giving botany a place in 

 our general scheme of education is that it is 

 the natural scientific background for the 

 great plant-producing arts. It is a text that 

 accords well with our motto, " Books that 

 apply the world's knowledge to the world's 

 needs "
