been plowed to a sufficient depth in previous years and there is 

 plenty of water for irrigation. 



4th: Disking stubble land after the grain is cut to put the 

 soil in better condition for fall plowing. This is a method 

 adopted by the dry farmer to conserve the moisture in the soil 

 and also to put the soil in better condition to catch and retain 

 the rain that falls upon it. The disk harrow is an excellent 

 implement for the formation of the soil mulch. 



5th: For summer fallowing. It not only helps the soil 

 retain moisture, but is a killer of weeds, which rob the soil of 

 much moisture. 



6th: Disking alfalfa fields and meadows. The fields become 

 sodbound and disking cuts up the crowns of alfalfa, loosens and 

 aerates the surface soil, cuts out foxtail and other injurious 

 weeds, and improves the crop generally. 



Yth: As a lawn improver. This spring a part of the Uni- 

 versity campus which had never been broken was disked and 

 seeded to native grasses. Also the court-house lawn was 

 covered with manure during the winter and this spring disked. 

 The lawns are now in excellent condition. 



8th: For cultivating the orchard. To give maximum yields in 

 the irrigated orchard regions the orchard should be given clean 

 cultivation. This can be done by the use of the disk harrow. 

 The dry farm orchard is also greatly benefited by disking and 

 clean cultivation to destroy weeds and conserve moisture. 



Taking the variety of work, the thoroughness, the horse 

 power required, the ease with which it can be handled and its 

 effect upon the soil, no farm machine ever invented surpasses 

 the disk harrow. And even though the inventor is unknown, 

 his memory is entitled to the blessing of humanity and he is 

 deserving of a monument equal in height and architecture to 

 any of the great benefactors of the race.
