7. FOREST PROTECTION, price $ 1.50 (registered mail 25 c). 



The book on forest protection deals with the various influences threatening the life of the forest. It is divided 

 into two main parts— the first dealing with the influence of organic nature (ravages by man, quadrupeds, birds, in- 

 sects, weeds, fungi, and that like)— whilst the second part deals with the damage done to the forest by natural 

 phenomena like wind storms, intense heat, frost, and so on. 



The most important paragraph of the book, naturally, is that which deals with forest fires— the main problem 

 of American constructive forestry.
