COST OF FARMING OPERATIONS 



the returns obtained in producing the great 

 staple farm products; yet one of the most 

 important and vital considerations in the 

 organization of a farm enterprise is the in- 

 come, both gross and net, which may be 

 expected from the different crops contem- 

 plated. Obviously the yield and price of 

 the several crops will vary with the locality 

 and with the season. It is, therefore, im- 

 possible to predict for any year either what 

 yield may be obtained or what price will be 

 secured. If, however, a sufficient number 

 of. years are selected, an average may be 

 found which will form a basis for calculat- 

 ing the probable result for another series of 

 years. The following table gives the yield 

 and the average farm values per acre for 

 five staple crops for five years, 1905-1909 

 inclusive, for the United States and for four 

 widely separated states, viz., Pennsylvania. 

 Iowa, Texas and Oregon.
