FORESTRY. 13 



to work irreparable damage by the removal of 

 the soil. 



It is for the purpose of regulating the necessary 

 removal of the forest, and for pointing out the 

 manner in which the products of the forest can 

 be most advantageously harvested, that Forestry 

 Associations and Forestry Laws are so imperatively 

 demanded. 



In order to intelligently protect forest areas, 

 and thus aid rather than oppose nature in main- 

 taining them, the principles underlying the growth 

 of trees, the conditions of heat, light, and moisture, 

 or, in general, the conditions of climate best suited 

 to continue such growth, must be carefully studied. 

 The natural influences or conditions which oppose 

 the growth of trees must be ascertained, and, 

 where possible, checked ; the enemies of the forest 

 recognized, and the best means taken to hold them 

 in check. In other words, forestry must assume the 

 position of an exact science, in order to call intelli- 

 gently for the passage of laws intended for insuring 

 the growth and reproduction of the earth's forests. 



It is a mistaken idea that forestry endeavors to 

 preserve intact the virgin forests of the earth. 

 This is by no means the intent of intelligent for- 

 estry.
