PURCHASING POWER PER ACRE. 



When the crop yield is unusually high or unusually low, the pur- 

 chasing power per bushel does not give an entirely accurate impres- 

 sion. For example, in December, 1917, winter wheat had a purchas- 

 ing power of 125 per bushel, or was 25 per cent higher than the 

 general price level. This is the way the price looked to buyers of 

 wheat. But the yield was poor and its purchasing power per acre 

 harvested was only 116. Many acres were abandoned and the pur- 

 chasing power per acre planted was only 87. Considering all 

 farmers as a whole, the price to them was more nearly represented

by the last figure, but their situation was somewhat better than 

 this because the abandoned acreage did not require the expense of 

 harvesting. 



The abandoned acreage for other crops is not known, but it is 

 possible to calculate purchasing power per acre harvested. Farm 

 prices for. other months than December are not available before 

 1908. December prices are therefore used. Since most farm prod- 

 ucts have declined more than the general price level the figures, 

 Tables XX to XXV, pages 67 to 72, do not show the full extent of 

 the agricultural panic. 



The purchasing power of cotton is shown in Table XXIV. At the 

 farm price December 1, 1920,. cotton had a purchasing power of 68 per
