PARAGRAPH XLI. 



FORESTRY INSTRUCTION, INVESTIGATION 

 AND STATISTICS. 



A. Instruction : 



In order to propagate a knowledge of forestry, and in order 

 to provide for a staff of foresters and rangers, a government 

 may appropriate money : 



1. to establish forestry schools at State universities; 



2. to establish departments or divisions of forestry, forest 

 commissions, etc.; and to publish their reports; 



3. to pay subsidies to forestry associations; 



4. to send teachers of forestry to farmer's meetings. 



However, the danger of "cranky" instruction by schools, re- 

 ports and teachers is great as long as men of practical ex- 

 perience are not available for the purpose. 



B. Forestry investigation and statistics: 



A knowledge of the financial possibilities of forestry is ne- 

 cessary for the owner of woodlands. Then, only, can he arrange 

 his investments so as make them most productive of revenue. 

 The knowledge must be based on investigation and statistics 

 gathered by the government, since the private individual is 

 usually unable to make them. He will never publish the result 

 of investigations which he may chance to make. Most desirable 

 are statistics on the following points: 



Growing stock of timber in the U. S. ; reproduction of tmiber; 

 influence of fires; yield tables, growth tables and volume tables; 

 log analysis as to quality and quantity of output; timber con- 

 sumption; timber export and import; study of foreign markets; 

 influence of forests on water supply for irrigation and navi- 

 gation; influence of the forest on rainfall; results and experien- 

 ces in prairie planting; silvics of the leading timber species.
