PREFACE 
THE trees described in this volume are those indigenous 
to the region extending from the Atlantic Ocean to the 
Rocky Mountains and from Canada to the northern boun- 
daries of the southern states; together with a few well- 
known and naturalized foreign trees such as the Horse- 
chestnut, Lombardy Poplar, Ailanthus and Sycamore Maple, 
It is hoped that this book will commend itselt ; 
To amateur botanists who desire a more extended and ac- 
curate description of trees than is given by the botanical 
text-books in ordinary use. 
To such of the general public as habitually live near fields 
and woods; or whose love of rural life has led them to 
summer homes in hill country or along the sea-shore ; or 
whose daily walks lead them through our city parks and open 
commons. 
To ali those who feel that their enjoyment of out-door life 
would be distinctly increased were they able easily to deter- 
mine the names of trees.
