than is necessary, or consistent with that object, inju- 

 rious, rather than beneficial effects, may be the conse- 

 quence. Land may be too rich for corn crops, and it is 

 better to keep it in a well balanced condition, or in a me- 

 dium state of productiveness, than in too fertile a con- 

 dition ; besides the climate may be unfavourable for 

 pulse crops, in which case a second year of herbage 

 would be preferable to beans or pease. 



It is proper now to state, the improved systems of 

 cropping in Norfolk, a district from which Scotland has 

 derived so much valuable information. The courses, 

 as recommended by that eminent agriculturist Mr Coke, 

 consist either of five or six crops. The five course is, 

 i. Wheat ; 2. Turnips ; 3. Barley ; 4. Clover ; 5. Grass. 

 The six course is, I. Pease ; 2. Wheat -, 3. Turnips ; 



4. Barley ; 5. Clover ; 6. Grass. 



It is now ascertained, that for a district possessing a 

 soil and climate similar to that in the neighbourhood of 

 Holkham, the alternate use of the five and six course 

 system, is the best husbandry, because pease will not 

 succeed more than once in ten years. 



We shall now proceed to consider the rotations of 

 six crops adopted in Scotland, where it is a favourite 

 system. 



Six years Rotation. 



In a light soil near Alloa, Mr Kerr of Lome's Hill 

 has adopted the following rotation : i. One half pota- 

 toes, one-half turnips ; 2. One-half wheat after pota- 

 toes, one -half oats after turnips; 3. Hay; 4. Pasture; 



5. Oats ; 6. Barley. 



Mr Robertson of Ladykirk proposes the following 

 rotations on a good soil, i. Potatoes or turnips ; 2. Bar- 

 ley ; 3. Grass 5 4. Potato oats; 5. Beans; 6. Wheat.
