On Rotations of Crops. 383 



only injures the crop of grain, but likewise destroys the clo- 

 ver and artificial grasses sown along with it (* 65 ). 



Six Years' Rotation. Rotations of six crops, are pecu- 

 liarly calculated for large farms. On small farms, and even 

 large ones near great towns, where manure can be had in 

 abundance, a succession of two, or of three crops, may be 

 safely adopted (* 65 ). But on large farms, a variety of arti- 

 cles ought to be cultivated, by which the risk of loss, either 

 from the weather, or the markets, is diminished ; fewer 

 horses are necessary ; and the labours of cultivation, can be 

 more equally divided, during all the seasons of the year. 



This species of rotation may be considered under the 

 three great divisions, of, 1. Clay lands ; 2. Sandy lands ; and, 

 3. Loams. 



1. Clay Lands. On wet or adhesive lands, which have 

 been long in cultivation, a fallow, and, in some cases, a fallow- 

 crop, once in six years, are strongly recommended ; the fa- 

 vourite rotation being, 1. Fallow, winter tares, Swedish tur- 

 nip, or cabbages ; 2. Wheat; 3. Clover; 4. Oats ; 5. Beans ; 

 6. Wheat. In Suffolk, the years for producing the clover 

 and the beans, are reversed (* 67 ). But for reasons to be af- 

 terwards assigned, clover cannot be too near the fallow. 



2. Sandy Lands. A rotation of six, may also be adopted 

 in sandy soils ; as 1. Carrots, tares, turnips, or potatoes ; 

 2. Barley, or oats, with seeds ; 3. Hay, or soiling ; 4. Pas- 

 ture ; 5. Pasture; 6. Oats( a<58 ). Under that course, such 

 soils become highly productive, and, instead of being ex- 

 hausted, improve in fertility. The first year's grass ought 

 not to be made into hay, unless where sheep have been fed 

 on the ground with the turnip crop, or the land is in good 

 heart. Indeed, if the soil be thin, it should be pastured 

 during the whole three years that it carries grass. 



3. Loams. On this species of soil the following plan is 

 recommended; 1. Turnips, or fallow; 2. Wheat, or bar- 

 ley ( z69 ) ; 3. Seeds, either clover alone, or clover and rye- 

 grass, with the addition of a little yellow or hop clover ; 4. 

 Oats; 5. Tares, pease or beans; 6. Wheat (* 7 ). 



Rich loams, adapted to this productive rotation, will pay the 

 highest rent of any, more especially when early oats are sown 

 after clover ; for invariably, on all friable soils, that grain is 

 the most beneficial of crops, seldom producing less than 60 

 Winchester bushels per English acre, and much more pro- 

 fitable than wheat, which is apt to be blighted. 



By this plan also, the crops are divided in a most advan- 

 tageous manner. All the most valuable grains are grown,
