TREES IN TOWNS

because their attractive fruits and flowers are apt to be picked. In 

 this case, the form of the tree is usually spoiled. Examples of trees 

 of this class are Chestnut, Hickory, Horse-Chestnut, Catalpa, Black 

 or Common Locust, Magnolia, Dogwood, Mountain Ash. The Catalpa 

 and Horse-Chestnut are really objectionable because of their mussy 

 habit of dropping flowers, young fruits or bud scales. 



Good street trees stand adverse conditions, are more or less free 

 from insects and diseases and furnish shade, but not too dense; they are 

 long lived, and those which are arching are preferred by many to the 

 more formal globular forms. Prof. Curtis of Cornell University, ad- 

 vises the following trees for various widths of street. 



For narrow streets (less than sixty feet between buildings), 

 the trees should be planted alternately and spaced forty feet apart. 

 The following may be 

 used: 



Pin Oak. A tree of 

 medium size, more 

 slender than most 

 Oaks; one of best 

 trees for narrow 

 streets. Especially 

 likes moisture, but 

 will adapt itself to 

 other conditions. 



Green Ash. A smaU 

 but hardy tree. It 

 is the species Frax- 

 inus pennsylvanica, 

 var. lanceolata. 



Tree of Heaven (Ai- 

 lanthus glandulosa). 

 This tree is excel- 

 lent for dry paved 

 tenement sections of 

 cities, enduring 

 smoke and dust. The 

 wood is brittle and 

 the trees are danger- 

 ous when they are 

 old. Because the 

 flowers of the male 

 tree emit a disagree- 

 able odor the female 

 form only should 

 be planted.
