OF ROTATION OF CROPS. 



sion which is kept in grass, and which is thrown out of the 

 rotation for three, four, or five years, and then brought in 

 again , so that each division, in its turn, remains in grass 

 for that period of time, in the course of twenty-one years' 

 lease. In lands which are not naturally fertile and produc- 

 tive, this plan must be attended with advantageous conse- 

 quences. Every part of a farm thus derives a proportional 

 share of the advantage of being kept in grass, which is in- 

 finitely preferable to the plan of preserving one part of a 

 farm constantly in grass, and the remainder under a rota- 

 tion of crops.* 



2. Rotations according to the Nature of the Soil. 



According to the nature of the soil, rotations may be 

 calculated for, 1. Clay-lands; 2. Loams ; and, 3. Light soils ; 

 and for all these soils, the six-course shift seems, on the 

 whole, to be the preferable system. . 



1. On Clay Land. I. Fallow; 2. Wheat ; 3. Clover ; 4. 

 Oats ; 5. Drilled beans and peas; 6. Wheat. 



Barley is excluded from this rotation, not being very fa- 

 vourable to the growth of wheat, and the latter being so 

 much more valuable. Peas should be mixed with the beans, 



* Another specimen of a double rotation is that recently adopted in 

 the estate of Mr Coke of Norfolk. That eminent agriculturist stipulates 

 for a course consisting of, either five or six crops. The five-course is, 1. 

 Wheat ; 2. Turnips ; 3. Barley ; 4. Clover ; 5. Grass. The six-course 

 is, 1. Peas ; 2. Wheat ; 3. Turnips ; 4. Barley ; 5. Clover ; 6. Grass. But 

 it is now ascertained, that for a district possessing a soil and climate si- 

 milar to that in the neighbourhood of Holkham, a double rotation, or 

 the alternate use of the five and six course system, is the best husbandry, 

 because peas will not succeed above once in ten years.
