EALTHY APPEARANCE is of the utmost im- 
portance in shade trees, and no agency is more 
potent in marring the appearance of these trees than 
are insects. A defoliated or otherwise bedraggled 
shade tree is not only worse than none at all but, 
when a result of insect injury, it is a menace to the 
health or life of similar trees in the neighborhood. 
Practical ways of controlling most of the injurious 
shade-tree insects are known. This bulletin dis- 
cusses the more important insects affecting decidu- 
ous shade trees in the eastern two-thirds of the 
United States with the exception of the gipsy moth 
and the brown-tail moth and gives the remedies for 
them. The gipsy moth and brown-tail moth and their 
control are considered in Farmers’ Bulletin 845.
