CAMPBELL'S SOIL CULTURE MANUAL 93 



indeed it is that so many through a chain of circumstances 

 have been led to look upon farming, especially the actual 

 tillage of the soil, as wearisome toil, uncertain of its re- 

 ward. 



If they could be only made to see that kind Provi 

 dence has intended that man should have dominion over 

 all things, and set themselves at work to learn how they 

 may intelligently command nature's resources that certain 

 obedience may be secured, then toil would be changed to 

 healthful, inspiring, agreeable work. 



We wish to prove to you that nature has provided 

 all necessary elements on these broad, level prairies of 

 the semi-arid belt to grow cereals, vegetables, forage and 

 fruits in such quantities and of such quality as to make 

 the most sanguine minds marvel, when proper tillage is 

 applied. 



To do this the tiller of the soil must learn what to do; 

 when to do it, how to do it, and why he works the soil 

 by this method which enables nature to reveal all the pos- 

 sibilities she stores in this workshop for an unlimited 

 supply of crop material. We will show you that it does 

 not require a vast amount of hard and expensive labor 

 to get large results, but it does require effort with knowl- 

 edge and judgment. Just as a valuable machine may be 

 made powerless and useless by the wrong or slack adjust- 

 ment of some bolt or nut, so in the mechanical preparation 

 of the soil success in the highest degree depends on doing 

 the right thing at the right time and in the right manner. 

 You could not put a valuable machine together unless 

 you knew something of mechanics. You cannot properly 

 till the soil and extract from it all that nature has stored 

 there for your use unless you understand some of the sim- 

 ple rules of soil physics,
