OF ROTATION OF CROPS. 339 



3. On light Soils. 1. Turnips or potatoes; 2. Oats or 

 barley ; 3. Grass ; 4- Grass; 5. Grass ; 6. Oats. Even 

 light soils, under such a rotation, would be productive, 

 and, instead of being exhausted, would improve in fertili- 

 ty. The grass, if it can be avoided, should not be made 

 into hay, unless where sheep have been fed on it, with 

 turnips. 



If, in addition to the rotations of six crops, one-seventh 

 part of a farm were thrown into grass, for three, four, 

 or five years, in the manner already described, so as 

 to extend the rotation, agriculture, on good soils, in so 

 far as regarded the rotation of productive crops, and the 

 preservation of the land in a state of permanent fertility, 

 would be brought to a considerable degree of perfection, 

 capable, at the same time, of improvement, where the 

 whole mind of an active and intelligent farmer is devoted 

 to the cultivation of his land. For instance, I have no 

 doubt, that in the generality of turnip soils, Mr Hunter of 

 Tynefield's system, described in the Appendix, No. XIII., 

 might be adopted; namely, 1. Turnips; 2. Wheat and 

 barley; 3. Clover ; 4. Oats or wheat, provided soiling were 

 adopted, and the whole straw of the farm were converted 

 into manure. In regard to strong lands, the system of, 

 l.Rape; 2. Barley ; 3. Clover; 4. Oats and wheat; 5. 

 Beans and peas ; and, 6. Wheat, which may be entitled to 

 the attention of the practical farmer.* 



4. Miscellaneous Particulars. Some particulars still re- 

 main, which it was difficult to comprehend under any of 

 the preceding heads.

 is necessary to commence with what may be called gentle
