nd manure wanted ; but it may be relinquished after - 

 wards for a better one. It is not indeed in general use 

 in any district, and has only been followed by some in- 

 dividuals, who have found it of benefit in the respects 

 above mentioned. 



Four years Rotation. 



Rotations of four crops, however, are by far more ge- 

 neral, and will require more ample discussion. The 

 first to be pointed out, is the celebrated Norfolk system, 

 namely, i. Turnips; 2. Barley; 3. Clover; and, 4. 

 Wheat. Even in Norfolk, however, this course is no 

 Jonger so generally recommended. It is considered pre- 

 judicial to the landlord; and, on a lease of twenty- one 

 years, if constantly persevered .in, it is contended, 

 would not be found profitable to the tenant. Half the 

 farm has annually a white straw crop, which, from the 

 frequency of the repetition, would not be productive ; be* 

 sides which, the number of sheep and cattle kept under 

 this system is comparatively trifling *. 



It may be proper to compare this rotation, with others 

 qn a similar principle, for dry soils. 



In Roxburghshire, Mr Walker of Mellendean's rota- 

 tion is in turnip and drilled beans ; in wheat and bar- 

 ley after turnips and beans, and sown down with grass- 

 seeds ; ^ in hay, soiling, and pasture-grass ; and in 

 wheat or oats, after hay and pasture. In the light soils 

 of Norfolk, neither beans or oats are cultivated. 



* See a communication on this subject from Mr Money 

 Hill, Esq; of Waterden to the author. Dr Coventry re- 

 marks, on the Norfolk system, that though the land on which 

 this scheme is pursued, seldom, if ever, becomes by it less fer- 

 tile, yet for poor ground it seemi not to be sufficiently mclio-
