Off. Doc. 



and the national and State Departments of Agriculture, together 

 with the farmers' institutes now organized in every State. These 

 institutions have undertaken to deal with the question of the future 

 supply of food products for the increasing population of our country 

 by scientific methods, through the accumulation and dissemination 

 of information respecting the laws of growth, and the discovery 

 of the principles that underlie profitable production. Notwithstand- 

 ing the efforts of all of these agencies the average production per 

 acre of the various crops has not been materially increased in the 

 last 36 years. The following data taken from the report of the De- 

 partment of Agriculture for 1906, and. from the census of 1900, 

 exhibit this feature:*
