be remembered that seasonal conditions may make more difference than 

 small variations in the acreage, in the production of a given crop in the 

 rotation. The land under rotation should be mapped, and records 

 kept to show the production from each tract under rotation, so that changes 

 in the rotation may be made intelligently when necessary.

THE CORNELL READING-COURSE FOR THE FARM 



ADVANCED READING 



To the Reader: 



The reading-course lessons are designed merely to introduce the subject; 

 they are elementary and brief, and are intended to arouse a desire for fuller 

 knowledge along particular lines. The study of reading-course lessons 

 should be introductory to the study of standard agricultural books and of the 

 bulletins of the United States Department of Agriculture and the state exper- 

 iment stations. The Supervisor of the Reading-Course will suggest, as far 

 as possible, agricultural literature to meet the needs of any reader. We do 

 not wish to recommend particular books or bulletins as superior to others on 

 the same subject, but will suggest those we believe will be of special interest 

 to the reader in his particular study.
