ciated. The corn crop of the United 
States for 1909 was valued at $1,720,- 
000,000. So much money has not been 
spent on higher education and scien-— 
tifie research since the first university 
was established. Each day this crop 
grows, it increases in value by $14,- 
000,000. An increase of six per cent. | 
in the productivity of the corn crop,

|Such as may result from a moderate 
| 
amount of research work, perhaps from 
the efforts of a single man, would be 
worth a hundred million dollars a 
year, 
Next to corn our most important 
crop is cotton, the value of which to 
the farmer last year was about $850,- 
000,000. The United States produces 
about three fourths of the world’s corn 
and about two thirds of its cotton.
