greater intervals — the increased richness of the land in the latter cases 

 has been attended with the greatest profit at the end. Forty bushels 

 of wheat from an acre once in four years, is far better than twenty 

 bushels once in two years ; for then three years of intervening crops 

 in the former, instead of two only in the latter case, are afforded for 

 other crops, which are much heavier besides. Hence those of the same 

 kind, occurring at remote intervals, prove most profitable, even though 

 for some of the intervening crops there may be little demand in mar- 

 ket. Take, as example, the results of a bad and of a good course, 

 which on many soils, would not be far different from the following ; 



1. A hard-cropping course — 1 acre. 



1st year, wheat, 20 bushels, $20 



2d do do 10 do 10 



3d do oats, 25 do 6 



4th do wheat, 8 do 8 



$44 

 The land diminished in value. 



2. A better rotation — 1 acre. 



1st year, wheat, 20 bushels, $20 



2d do clover & grass, 1 J tons, 12 



3d do do 1^ tons, 12 



4th do corn, 40 bushels, 15 



$59 

 The land not diminished in value. 



A rotation proper for one country, or for one district, may be en- 

 tirely unfitted to another. It must be particularly adapted to the re- 

 gion where it is employed, so as to suit the climate, soil, and market; 

 and be so arranged as to distribute the labor of the farm as equally as 

 possible throughout the season. As these must ever vary more or less 

 according to circumstances, some judgment and discretion is always 

 to be used by the farmer in so arranging the rotation as at the same 

 time to afford the best means of enriching the farm, and of affording 

 the most profitable returns. To facilitate this, the leading principles 

 upon which all rotations are founded, should be well understood. 



1. Or)e of the most important of these principles, is — every plant.} 

 during growth^ exhausts the soil on which it grows. Plants derive 

 a part of their support from the soil, through the roots, and a part 

 from the atmosphere, through their leaves j hence the soil continues
