22 FOREST INFLUENCES.

 tions. 



In conclusion I may urge that systematic observations bearing' on 

 tlie subject of foreign influences should be instituted in tliis country 

 by a Government agency, perhaps under the authority of the Weather 

 Bureau and with the cooperation of the agricultural experiment sta- 

 tions. No other country is so well adapted for the study of this ques- 

 tion as the United States, ottering all the varying climatic conditions 

 of a whole continent under one government, with changes in forest con- 

 ditions constantly progressing.
