INTRODUCTORY 



This edition of "The Disk Harrow" is presented to its 

 readers with the hope that its contents will be thoroughly 

 digested, and that part assimilated which will be of 

 special value to each individual reader. 



The contributors are situated in different parts of 

 the country. Their statements prove that while the soil 

 conditions are different in each locality, yet the principle 

 underlying the preparation of the seed bed is one and the 

 same all over the universe. It is simply a matter of 

 understanding the fundamental principle and then ap- 

 plying this knowledge to local conditions. 



Each contributor is a man of wide experience in 

 the field of agronomy. He has also made special study 

 of the use of the disk harrow in the locality where he is 

 situated. Several of them are fully acquainted with 

 conditions in many different states. For this reason 

 farmers can feel assured that these men have a message 

 of value to them
