SOME MORE GOOD BOOKS 



TREES FOR AMERICAN GARDENS. 



Donald Wyman. $7.50. 



If we could afford to give each of our customers a book

 Gardens," by the same author. We can't, but we suggest 

 you purchase one or both. With the knowledge you will 

 gain you will be able to answer almost all questions asked 

 you about all the most desirable trees.

A BOOK WE RECOMMEND 



THE HOW AND WHY OF BETTER GARDENING. 



Laurence Manning. $3.00. 



This book will show you how to grow better flowers, fruit, 

 shrubs, trees and vegetables, because it contains the basic 

 principles of plant science, described in an easy-to-read 

 way every gardener can understand and use. 



"Mr. Manning has the almost unique quality of being at 

 the same time highly instructive and enormously enter- 

 taining. He entertains while teaching and teaches while 

 entertaining. Once I'd started 'The How and Why of Better 

 Gardening' I found myself virtually incapable of putting 

 it down, and I'm sure that countless other gardeners who 

 start it — beginners and old-hands alike — will find themselves 

 in the same predicament." — Theodore A. Weston, Editor, 

 "Flower Grower Magazine." 



Davidia Involucrata (Dove Tree; 



One of the rarest really good trees in the 

 United States today. 



This is the tree the late Ernest Wilson spent months look- 

 ing for in the heart of China. After seeing it in bloom he said, 

 "I am convinced that Davidia Involucrata is the most inter- 

 esting and most beautiful of all trees which grow in the 

 north temperate regions." The beauty of the Davidia is in 

 the two snow-white bracts which are always unequal in 

 size — one usually six inches long by three inches broad, 

 the smaller three and one-half inches by two and one-half 

 inch. At first greenish, they then turn pure white as the 

 flowers mature. They are pendulous on fairly long stalks and 

 when stirred by the slightest breeze they resemble small 

 doves nestling among the trees. 3 to 4 ft. at $17.50 each.
