Preface 



The preparation of the first edition of this Manual of 

 Corn Judging was prompted by the need of such an out- 

 line in my class room. During the following winter it 

 was found to be useful in the work of the various schools 

 of corn judging, farmers' institutes, fairs and like places, 

 where corn was studied. The entire edition was quickly 

 exhausted, and in response to a continued call for addi- 

 tional copies I have made arrangements to issue this edi- 

 tion. In view of the constant improvements in the 

 methods of judging samples, I have taken the opportunity 

 to make a few changes and additions to the matter pre- 

 sented in the first issue. 



I beg leave to express my sincere thanks for aid in the 

 preparation of this work, to Mr. 0. A. Shamel and others 

 who have kindly assisted me in the arrangement of the 

 material in the Manual. 



It will probably be necessary to issue editions every year 

 or so, in order to keep abreast of discoveries and the re- 

 snte of investigations in corn. In this way it will be pos- 

 sible to present the very best information to the corn 

 students.
