of conforming our artificial crops to the rules which 
obviously governed her spontaneous productions, 
The effect was such as was expected, and for more 
than half a century, the rotation system has formed 
the true test of agricultural improvement, in every 
variety of soil and climate. Whenever it has been 
adopted, the art is found in a state of prosperous 
progression; whenever neglected or rejected, it is 
either stationary or retrogade. Yet in the face of 
a fact, carrying with it such conclusive evidence, 
the bulk of agriculturists continue to resist this cheap. 
and obvious means of improvement, and pertina- 
ciously adhere to a system (that of fallows) which 
condemns to annual sterility, one fourth part of the 
earth, and even prefers four months unproductive 
labor, to abundant harvests and nutritious crops! 
But from this display of folly, let us turn to one of 
wisdom. : | 
On the rotation system, the whole arable part of 
a farm is divided into four, six or eight fields, and 
subjected to a course of crops, denominated (ac- 
cording to the number of these divisions) the short, 
the medium, or the long course, In constructing 
these courses, however, whether long, middling or 
short, the utmost attention is paid to the nature of 
the soil, viz: In all soils more wet than dry, more 
compact than porous, more hard than friable, the 
course is made up from the following plants: wheat, 
oats, buckwheat, the gramineal grasses, beans, vetch- 
lings, clover, cabbages and chicory. In soils of an 
opposite character (dry, porous and friable) the
