The diseases of the more common trees of the United 

 States are treated in this volume. The discussions of 

 these diseases are grouped into chapters under the com- 

 mon name of the tree affected, and the chapters are ar- 

 ranged alphabetically. In a general chapter are included 

 discussions of the diseases common to all kinds of trees, 

 such as samping-off of seedlings, temperature injuries to 

 leaves and woody parts, smoke and gas injuries, wood- 

 rots, and the like. The species of trees affected, the 

 geographic distribution, destructiveness and symptoms of 

 the different diseases are presented in full. The casual 

 agent of the diseases is briefly described, and when it is 

 caused by a parasite some details of the parasite's life 

 history and activities are given with suggestions as to 

 control. Special attention is paid to tree surgery. Tech- 

 nical details and terminology are omitted so far as possi- 

 ble, and those terms used are explained in a glossary. 

 The aim of the authors has been to furnish a descriptive 

 guide for the diagnosis of tree diseases and the general 

 methods of their control.
