In order to study the relative effects of the fertilizers on the 

 crops of peas and barley, the following tables have been made 

 showing the yields per acre of Barley, Black-eyed Peas and 

 Canada Peas, on the different plots, together with the calculated 

 yields had no fertilizers been applied, and the calculated gains 

 due to fertilizers.
