86 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.
