A.S aids to study, these academies have extensive collections relating to 

 forest and natural science, botanical gardens, seed collections, etc. Each academy 

 is under the direction of an oberforstmeister. The lectures are given by scien- 

 tifically educated foresters and special professors. The student, before he is 

 admitted to these academies, must produce a diploma showing that he has passed 

 the course of studies required at a German gymnasium or at a Prussian 

 technical school of the first class. He must be under 25 years of age. have a 

 good character and show that he possesses the necessary means for studying. 



EFFECTS OF FOREST DESTRUCTION. 



The destruction of forests is caused mostly by parcelling off large forest 

 estates, which leads to a careless felling of the trees and little disposition to 

 restore the loss. An eminent authority on forestry science, Dr. Otto von Hagen, 

 in writing on this subject makes the following observations : 



"The forest is a trust handed down to us from past ages, whose value con- 

 sists not alone in the income derived from wood, but also in the importance 

 which it exerts, through its influence on Climate and rainfall, on land culture. 

 Its importance is not merely a question of the present day or of the present 

 ownership, but is also a matter which concerns the future welfare of the people. 

 This is a truism beyond contradiction, but nevertheless it is daily disregarded by 

 those who are indolent and selfish.
