The above facts, including the tables of statistics, show 

 the extent of our dependence on the presence of chemical 

 compounds in the various plant sources from which we derive 

 many of our supplies. 



The consideration of the cereal products of the United 

 States and our domestic sugar supply in relation to this subject, 

 seems of sufficient importance to detain us for a few minutes. 



"The total production 1 of the six principal cereal grains of 

 the United States for the census year amounts to 2,697,962,456 

 bushels, an average of 58.8 bushels per head for the whole 

 population. The total breadth of cultivation and the amount 

 of product of each of the grains is as follows :

"Whether considered in respect to breadth of cultivation, 

 total product, or average production per head of the whole 

 population, these figures place the United States at the head 

 of the grain-producing countries of the world." . . . "The 

 tables of cereal production, taken in connection with the 

 tables of other production, and these compared with the 

 returns of previous census years, show that agriculture con-
