96 AGRICULTURE. 



the roots has by this time been well worked over. Last comes 

 the wheat with roots of medium length, feeding in the fall 

 and spring and coming to maturity in the summer of the 

 fourth year. A variety of crops for the farmer's use is at the 

 same time obtained. 



Here are some other rotations that may be examined :

The system, of course, must be suited to the soil, the kind 

 of farming adopted, and the circumstances of the farmer. 

 Rotations may have to be changed from time to time, but, if 

 the principles upon which rotations are based are well 

 understood, there will be no difficulty in making changes, and 

 in forming rotations suitable to the needs and conditions of the 

 farm. The four-course rotation may be taken as a basis, and 

 changes made to lengthen it ; thus corn may be put in place 

 of roots, and barley may be seeded to clover and timothy^ and 

 a year or two of hay and pasture, or both, may be had before 

 returning to a cereal crop. If the soil is the farmer's capital, 

 then growing the same crop year after year leaves part of the 

 capital idle. Rotating the crops causes all of the capital to do 

 its share in turn in producing income, and, it may be, in 

 increasing the amount of capital.
