Grain. Grain fields are usually 'irrigated by flooding from field 

 laterals. Furrow irrigation is practiced only where the soil bakes 

 after 'being flooded. Grain is essentially a crop for the farmer with 

 a very limited capital or for the farmer on new land. It is not ad- 

 visable to grow many crops of grain in succession on new land, 

 as the yields fall off rapidly. The land should be seeded to alfalfa, 

 and grain used only in rotation after the first year or two. There is 

 very little difference in the farm value of wheat, oats, and barley 

 crops per acre, and for that reason the wheat crop is taken in estimat- 

 ing the gross and net returns per acre. The yield will average at least 

 40 bushels per acre and the price per bushel of wheat is taken at 75.1 

 cents.
