ROTATION OF CROPS 209 



tillage area is being dressed with fertilizers 

 of one kind or another, a condition of things 

 that fairly merits the term " high farming." 

 It is evident, of course, that this six-course 

 rotation can at once be converted into a 

 rotation of seven years, by leaving down the 

 seeds for two years instead of one. 



On very strong land, such as is met with 

 in the Holderness district, a six-course rota- 

 tion is practised which bears this name, 

 and may be set out as follows : 



1. Turnips, swedes, cabbages, or mangolds. 



2. Wheat. 



3. Beans or clover. 



4. Wheat. 



5. Clover or beans, the beans being put 



on land previously under clover and 

 the clover on land previously under 

 beans. 



6. Wheat. 



With the exception of the turnips these 

 crops are all strong-land crops, and it will 

 be seen that three-sixths, that is, one-half, 

 of the farm is annually under wheat, while 

 other two-sixths is under a nitrogen-col- 

 lecting, i.e. a leguminous, crop. 



On the strong carse land of central Scotland 

 the following eight-course is not unusual :
