TREES AS GOOD CITIZENS 
under trying conditions, make slower progress than trees 
of the same character planted early the following spring. 
In mild climates, this is not a factor, and fall planting is 
followed by good results. Except in climates where the 
ground does not freeze in winter, a few kinds of trees like 
Magnolias, Tulip and Sweet Gum should be transplanted 
only in spring. Evergreens should be planted when the 
ground is warm. It is usually done in late spring or early 
autumn. 
THE FOLLOWING MAP AND TABLES SHOW TREES SUITABLE FOR 
PLANTING IN DIFFERENT AREAS 
The map and tables should be consulted in selecting trees, and determining 
their suitability for different regions. The numbers on the map show regions indi¬ 
cated by similar numbers in the tables. 
KEY TO CHARACTERS IN TABLES 
Numbers I to 32 in tables indicate the regions marked by number on the map. 
S—Trees most desirable for street and roadside planting in regions numbered, 
s—Trees less desirable but will grow. 
R—Trees suited for country roads but not for city streets, 
a—Trees suited only for southern parts of regions numbered, 
b—Trees which require watering for a few years, 
c—Trees worth trying although their adaptability is uncertain, 
d—Trees suited only to northern part of region numbered, 
n—Trees that are undesirable.
