OF ROTATION OF CROPS. 33S 



Six Years' Rotation. In a light soil near Alloa, Mr Kerr 

 of Lome's Hill has adopted the following rotation : 1. One- 

 half potatoes, one-half turnips ; 2. One-half wheat after 

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

 .5. Oats ; 6. Barley. Here, however, there are two white 

 crops in succession. Perhaps it would be advisable to con- 

 vert it into a rotation of five, leaving out the barley or the 

 sixth crop, and putting barley instead of oats after turnips 

 the second year. Nothing can succeed barley with so much 

 advantage, as clover and grass-seeds. Mr Rennie of Phan- 

 tassic likewise observes, that in good lands, pasture ought 

 never to succeed hay, which ought to be taken as a crop, 

 and ploughed after. 



Mr Robertson of Ladykirk proposes the following rota- 

 tions on a good soil: 1. Potatoes, or turnips; 2. Barley; 

 3. Grass ; 4. Potatoe oats ; 5. Beans ; 6. Wheat. On in- 

 ferior soils, 1. Turnips, or fallow; 2. Wheat, or oats; 3. 

 Clover ; 4. Pasture ; 5. Pasture ; 6. Angus oats. 



On all the strong lands in the Carse of Gowrie, and in 

 other fertile districts in Scotland, the following rotation of 

 six crops, with some variations, is considered as preferable 

 to every other: 1. Fallow; 2. Wheat; 3. Beans; 4. Bar- 

 ley; 5. Grass; 6. Oats; and, as it seems to be admitted, 

 that on strong lajids in Scotland, fallow is necessary once 

 in six years, there cannot, on the whole, be a better system 

 for such soils. Where wheat can be taken the fourth year, 

 instead of barley, the produce is still more valuable. By 

 some farmers, the course is altered in the following man- 

 ner : 1. Fallow; <-2. Wheat; 3. Clover; 4. Oats; 5. Beans; 

 6. Wheat. This seems to be on the whole the best sys- 

 tem, for the clover will produce a more abundant crop when 

 it succeeds wheat after fallow, than when it is the second 

 crop after beans ; and Mr Rennie of Phantassie observes, 

 that this system will be less expensive in the culture than
