B4 FALLOWING. 



It is difficult to determine what particular routine of 

 crops is best. Green and white crops, alternately, are 

 in general reconrimended. Soils differ so greati}^ even 

 in fields which lie contiguous, that the course ot^ crops 

 which is suitable for one is unsuitable for another. 



The following important rules, in regard to rotations, 

 are particularly recommended. 



1. When any farm begins to be improved, it is neces- 

 sary to commence with such crops as are the most likely 

 to produce manure ; nor should two exhausting crops be 

 attempted, in succession, until the soil has acquired a 

 considerable degree of fertiiity. 



2. The crops should be so arranged, that the labour 

 of ploughing for each, and of sowing, weeding, reaping, 

 &:c. shall proceed in a regular succession. 



3. All forcing crops, or frequent repetitions of the 

 same articles or species, should be avoided ; as a dimi- 

 nution both in the quantity and quality of the produce, 

 is the usual consequence. In soils of moderate fertility, 

 the greater the distanxe, at which the repetition of any 

 sort of crop can be kept, the better. 



4 Tho e crops should be mixed, which are known to 

 be most productive of manure, and are best calculated 

 for the extirpation of weeds. Hence it ia better to cul- 

 tivate a greater proportion of green crops than of grain. 



It is supposed that hemp- carrotts, onions and buck- 

 wheat, may be cultivated successively upon the same 

 grounds for many j^ears ; but clover, potatoes, and In- 

 dian corn, oats and barley, wheat and rye, v.ill not an- 

 swer well for more than two years, without high naanu- 

 ring; and even then, they do best under a change of 

 crops ; flax will not succeed well upon the same ground 

 oftener than once in seven years, therefore, a larm 

 should be so arranged as to have a regular routine of 

 crops, once in four, five, six or seven years, according 

 to the nature or circumstances of the farm. Where 

 circumstances render ploughing not so advantageous as 

 pasturing, the land may remain in grass till these cir- 

 cumstances are obviated ; care being always taken, 

 when it is broken up, to follow alternate husbandry du- 

 ring the time it is under tillage. In this way the alter- 

 nate system can be followed in every situation ; nor do 

 we consider the land being in grass for two, three or
