398 DRY LAND FARMING 



feasible to so divide any farm, large or small, that the 

 succession involved in this rotation may be conducted 

 on it. Suppose, for instance, that the farm has in it 

 160 acres. If 40 acres are set aside for hay or pasture, 

 120 acres will be left for cropping. If the 120 acres are 

 divided into four equal parts, the rotation may be intro- 

 duced as outlined. In this rotation 60 acres will be 

 cultivated each year by the fallow or by the cultivated 

 crop, and the remaining 60 acres will be devoted to the 

 growing of cereal crops. On one-half of the cultivated 

 area a crop will also be grown, hence but one-fourth of 

 the land that is cultivated from year to year will be idle. 



This rotation is attended with the following benefits: 

 (1) it keeps the land in a clean condition; (2) it makes 

 practicable the growing of fodder on the farm, as corn for 

 instance ; (3) it is not only not antagonistic to a wider 

 rotation, but is helpful to the same, since it makes pro- 

 vision for the growing of hay and pasture, and to any 

 extent that may be desired, as the rotation is practicable 

 on any residue of the land left after the hay and pasture 

 land is set aside, providing the said residue is divided 

 into four parts. 



This rotation will probably be extensively adopted 

 in the semi-arid country, since it favors the introduction 

 of live stock onto the farms. It cannot be successfully 

 practised on so small an amount of precipitation as will 

 bring a crop of small grain once in two years, on the 

 summer-fallow plan, but it can be practised on a rain- 

 fall somewhat less than will suffice to grow corn or the 

 other cultivated crop in combination with small grain 

 each alternate year. In this rotation, where winter wheat 

 may be successfully grown, it should be made to come 

 after the bare-fallow, and other spring crops after the 

 cultivated crop. 



The objections to it include the following: (1) it 

 makes no provision directly for putting back on the land
