Tables XV, XVII, and XIX present in convenient form for com- 

 parison the yields per acre of each rotation for each test and each 

 crop, the average yields for continuous cropping, and the losses or 

 gains as compared with crop rotations for each test. 



In Tables XVI, XVIII, and XX the yields are expressed in farm 

 values per acre instead of in bushels, Tables XV and XVI, XVII and 

 XVIII, XIX and XX being, respectively, companion tables dealing 

 with the same crops, but using different terms of expression.
