which a full understanding of all the points may be reached. 

 There is no subject today the full knowledge of which 

 means so much to the farmer as how to get the most out 

 of his soil, for it is the key to his prosperity and happiness.

 ticulars by addressing H. W. Campbell, at Lincoln, Nebr. 

 There is so much to be made known on the subject that 

 the farmer will not be able to get it all in one book or 

 in one year.
