 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.
