as far as its balance is concerned, less able to yield a 

 paying crop than before. The careful fertilization of the 

 rotation, then, with special attention to the money crop, 

 is the only rational system that can ordinarily be employed, 

 since it not only cares for the crop on the land but also 

 looks to those that are to succeed. The attention that 

 must necessarily be paid to the fertility of the soil in such 

 a system insures the establishment of a soil management 

 which will ultimately result in a great conservation of 

 fertility, while at the same time raising the yields and 

 increasing the prosperity of the farming class.
