published in its year book for 1909. Statistics of the yield per 

 acre of wheat foi periods of ten years each since 1866 showed a 

 steady, though small increase of yield per acre. Using this as a 

 basis of calculation, and ignoring the probable factors that will 

 accelerate this rate, it showed that the bread supply will not 

 only keep pace with the increase of population, but that in the

year 1950 there will be a surplus of 200,000,000 bushels of wheat 

 in the United States. That a large increase in the yield of 

 wheat from one acre of land is possible, no one doubts; and the 

 future surely promises also an increase over large areas in the 

 yield from each acre of wheat, and an end to the low averages 

 now so generally reported from all the wheat growing sections 

 of our country.
