Plants: What They Are and 
What They Do 
By A. C. Seward 
31 illus.; ! 41 pages; 5*/8 x 8*/2 inches 
This book presents a few aspects of plant life, in 
language as free as possible from technical terms, to 
readers who have little or no knowledge of botany 
or other branches of natural science. Dr. Seward 
shows some of the more striking attributes of the 
humbler organisms in order that we may be in a 
better position to appreciate what the world owes to 
plants. 
Plant Names 
By T. S. Lindsay $1.00 
99 pages; 4%. x 7•/j inches 
This little book explains why, with the tens of 
thousands of plant species, it is necessary to have a 
system of plant names in order that each species shall 
have a name by which it can be identified, and in 
order that botanists and horticulturists of all lands 
and languages may know it by the same name. 
An entirely new joy and significance await those 
who—with this helpful little volume—set out to 
learn how plants are named, why they received their 
particular titles, and just what each word form, 
prefix or suffix means.
