THE CORN CROP. 



FIG. 3. The light black line shows the crop yield of Ohio from 

 1874 to 1903. The dotted line shows the crop yield of the U. S. The 

 heavy black line shows the general tendency in crop yields from 1870 to 

 1890 and from 1890 to 1903. 



TENDENCY OF CROP YIELDS PER ACRE. 



In the above chart the downward tendency until about 1890, and 

 since then an upward trend, is strikingly shown. The recent tendency 

 toward enlarged production per acre is general throughout the United 

 States; it is not due to a shifting of production from one section to 

 another. "For the United States as a whole, and for most States, it 

 can not properly be said that yields are diminishing. In most civilized 

 countries of the world the yield per acre of crops has been tending up- 

 ward in recent years." The Crop Reporter. 



But there is another significant fact that stands out clearly 

 in relation to the history of this last period from 1890 to 1910, 

 and it is this: that our Experiment Stations, Agricultural Col- 

 leges, and Agricultural Schools in the United States date prin- 

 cipally from 1890 to 1910.
