Forest Insects 



Destroy Millions 



Annually 



Exact knowledge of conditions in 

 your forest holdings is good prepared- 

 ness against ruinous insect invasions. 

 Destructive Forest Insects cause con- 

 stant and serious yearly losses in forest 

 capital that are avoidable. Small 

 isolated patches or groups of dying trees 

 may mean extensive insect killing if 

 neglected. The economic control of 

 forest insects prevents serious epidemics 

 and reduces your forest fire risk. What 

 per cent of your timber is killed each 

 year? Find out. To know this is good 

 business assurance on all forest holdings. 

 Have your timber lands examined. 

 Efficient inspection of Parks, Water- 

 sheds, Estates, and Timber Lands any- 

 where in the United States or Canada. 

 Control methods recommended. Con- 

 trol costs estimated. Control work 

 supervised, if desired.

ALL nature-lovers will hail this book 

 i with delight. Its purpose is to 

 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.
