Eight years Rotation. 



The last rotation which it is necessary to point out, is 

 a course of eigLt crops, an example of which has been 

 transmitted to me bj Mr Andrew of Tillilumb near 

 Perth. His plan is, i. Fallow or Potatoes ; 2. Wheat ; 

 3. Beans; 4. Wheat ; 5. Barley, 6. Grass; 7. Oats; 

 8. Wheat ; but he does not recommend this rotation ex- 

 cept in situations where the ground is good, and of some 

 strength, and where there is a command of town ma- 

 nure. His great object in following this plan is, to re- 

 move his grass crops at a great distance from one ano- 

 ther, and he thinks they are so much the better. Last 

 year he had a field in grass, the one half of which 

 happened to be the fifth year from a former grass, and 

 the other the eighth. That in the eighth year had near- 

 ly one-half more of grass upon it than the other, and 

 this year he is persuaded that it will produce two bolls 

 more of oats per acre, though they had been both equal- 

 ly dunged and dressed for the barley. 



$-Of double Rotations. 



There is a mode of cropping to which I think the 

 name of a double rotation may be given. It is where a 

 particular course is laid down, but where part of the 

 farm is alternately put under different crops, so as to 

 prevent too frequent a repetition of the same sort of 

 grain, on the same spot. Mr Wood of Milrig proposes, 

 on that principle, to cultivate 1000 acres of convertible 

 land, under the following system :
