322 OF ROTATION OP CROPS. 



are by far more general, and will require more ample dis- 

 cussion. The first to be pointed out, is the celebrated 

 Norfolk system, namely, 1. Turnips; 2. Barley; 3. Clover; 

 and, 4-. Wheat, which has been adopted in several parts of 

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

 longer so generally recommended. It is considered preju- 

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

 if constantly persevered in, it 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; besides which, the number of sheep 

 and cattle kept under this system is comparatively trifling,* 

 when compared to the improved rotations which have late- 

 ly been introduced. It is also much doubted, whether 

 wheat will prosper so near the barley crop; and it can 

 hardly be questioned, that without a plentiful supply of ex- 

 tra manure, both the turnip and the clover crop will fail, 

 unless the land is refreshed by grass, for at least two or three 

 years. 



It may be proper to compare this rotation, with others 

 on a similar principle, for dry soils. 



In Roxburghshire, Mr Walker of Mellendean's rotation 

 is, one-fourth in turnip and drilled beans; one-fourth in 

 wheat and barley after turnips and beans, and sown down 

 with grass-seeds ; one-fourth in hay, soiling, and pasture- 

 grass ; and one-fourth in wheat or oats, after hay and pas- 

 ture. In the light soils of Norfolk, neither beans nor oats 



* Dr Coventry remarks, 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 seems not to be sufficiently meliorating, or 

 fitted soon to raise land to that degree of productiveness in which it is 

 found to be the most valuable to the cultivator.
