AMERICAN FORESTRY 



rapidly than ever before, as a direct 

 result of the application of modern 

 lumbering methods and of the strong 

 stimulus which agricultural develop- 

 ment has received. The value of the 

 remaining forests will be diminished by 

 the destruction of the more valuable 

 tree species. It will become excessively 

 difficult in many regions to obtain fire- 

 wood and building materials. Condi- 

 tions as to rainfall and run-off will be 

 unfavorably influenced and the supply 



of water needed for irrigation during 

 the dry season will be diminished. 



It is too much to expect that the 

 present generation of Filipinos should 

 adopt adequate measures to provide 

 against these dangers. The Congress 

 of the United vStates should provide 

 specifically for the continuance of the 

 Philippine Forest Service so that the 

 ignorance and extravagance of the 

 present generation may not inflict 

 irreparable loss upon the generations 

 that are to come. 



SELECTING SHADE TREES 



By S. B. Detwiler 



TREES are a constant inspiration 

 to an appreciation of the beau- 

 ties of nature; they cool the air 

 in Slimmer and temper the cold 

 winds of winter. They furnish a nesting 

 place and shelter for birds and counter- 

 act the adverse conditions of city life. 

 They purify the air, encourage outdoor 

 life and have a vast educational influence 

 upon the citizens, especially children. 

 They enhance the beauty of architec- 

 ture, increase the value of real estate, 

 and conserve soil and moisture. 



Through a love of the trees the people 

 of the United States are beginning to 

 comprehend the need not only for 

 planting shade trees and protecting 

 them, but for the protection and more 

 rational use of our splendid forests. 



The American Forestry Association is 

 devoting its influence to the develop- 

 ment of public thought and knowledge 

 about trees and forests along practical 

 lines. 



This article is limited to general 

 information about selecting shade trees. 



To those who desire detailed advice 

 concerning forestry problems or who 

 are in need of a complete plan for 

 forestry operations, the American For- 

 estry Association is prepared to mail 

 expert advice upon application. 



Attention is also called to State for- 

 estry departments, State forestry associ- 

 ations and city foresters Departments 



from which reliable and unprejudiced 

 infomiation may be obtained. Those 

 who desire to plan and direct their own 

 forestry work are strongly urged to out- 

 line a definite and complete program of 

 operations before the work is started. 

 This will insure close attention to prac- 

 tical details and will help to avoid annoy- 

 ing mistakes. 



SHADE TREES 



The selection oj species is a matter of 

 primary importance in shade tree plant- 

 ing. In deciding this point the climatic 

 and soil conditions and the location of 

 the tree or the purpose for which it is 

 desired must be considered. In the 

 past the tendency has been to plant 

 quick growing trees for immediate effect 

 regardless of their qualifications. The 

 results invariably have been highly 

 unsatisfactory. In the lists given below 

 are enumerated trees suitable for various 

 purposes and planting sites. The trees 

 printed in italics are those which are 

 most desirable. 



STREET TREES FOR PLANTING 

 UNDER SEVERE CONDITIONS 



Oriental Sycamore. — Hardiest of all for 

 street planting, not liable to insects, 

 rapid growth. Deep rooted, adapted to 

 a great variety of soils. Will require
