moist soil where it will make a picturesque growth. Its 

 doubly compound leaf adds greatly to its attractiveness. It 

 should be planted only under most favorable soil conditions. 



SOME OBJECTIONABLE SPECIES THAT SHOULD 

 BE AVOIDED FOR STREET PLANTING. 



1. SILVER MAPLE (Acer saccharinum) . 



The Silver Maple is a rapid growing shade tree that pro- 

 duces weak branches, easily broken by storms and injured 

 seriously by insects and fungi. It does not deserve the favor 

 that has been given it in the past. 



2. Box ELDER (Acer negundo.) 



The Box Elder is a medium sized, rapidly growing tree. 

 It thrives well in rich soils but is short-lived on poor soils. 

 It is a scraggly tree and is badly infested by insects. It 

 should never be planted along streets. 



3. SYCAMORE MAPLE (Acer pseudoplatanus) . 



The Sycamore Maple is similar to the Norway Maple in

The Horse Chestnut is beautiful in spring and early sum-

 not desirable for street decoration. It is a coarse, stiff tree, 

 attacked by insects and fungi and soon becomes so weakened 

 as to prove a source of danger to the public. 



5. HARDY CATALPA (Catalpa speciosa). 



The Hardy Catalpa is a moderate sized tree that has 

 ungainly branches and produces foliage and fruit that con-

 trees for street planting. 



6. CAROLINA POPLAR (Populus deltoides). 



The Carolina Poplar is a very rapid grower. It is useful 

 as a temporary shade tree and under special handling can be 

 used where few other trees would grow. But it should be
