ALL nature-lovers will hail this book 

 with delight. Its purpose is to 

 L afford an opportunity for a more 

 intelligent acquaintance with American 

 trees, native and naturalized. The 

 pictures upon the plates have in all 

 cases been photographed direct from 

 nature, and have been brought together 

 in such a way that the non-botanical 

 reader can recognize at a glance either 

 the whole tree or the leaves, flowers, 

 fruits, or winter twigs, and thus be able 

 to identify with ease and certainty any 

 unknown tree to which his attention 

 may be called. In the discussion of the 

 text especial attention has been given 

 to the distinguishing character of the 

 various species, as well as to the more 

 interesting phases of the yearly cycle 

 of each, and the special values of each 

 for ornamental planting.
