From the above summary it is possible to estimate 

 the gigantic work, in so far as material means are con- 

 cerned, which is undertaken by the federal and State 

 governments for the teaching of agriculture and the 

 promotion of agricultural research. This army of 

 graduates and students is distributed all over the coun- 

 try and through our territorial possessions. They 

 carry with them the principles of scientific agriculture, 

 and by precept and example are able to teach these 

 principles to the farmers at large. It is somewhat re- 

 markable, in view of these tremendous expenditures of 

 energy directed towards the improvement of agricul- 

 tural conditions, that the average yield of the fields has 

 been increased, if at all, by only small quantities. The 

 ravages of disease and the scourges that infect, annoy 

 and destroy crops and farm animals, are yet apparently 

 unchecked. These negative results, in so far as prac- 

 tical advantages are concerned, are, however, not to 

 be too seriously considered. A third of a century ago
