EXPERIMENTAL FARMS. 



of Wonder of the "World. The accompanying table gives the yield of each variety for 

 ■each plot and the total yield both in tons and bushels per acre. 



Those after barley were planted May 8th came up May 21st and were dug Sep- 

 tember 22nd. On each of these plots there were 12 rows of Thorburn, 1 2 rows of Beauty 

 of Hebron, and 3 rows of Early Rose. In the table the yield of each variety for each 

 plot is given, also the total yield both in tons and bushels per acre. 



The average yield of the different varieties per row putting the plots all together is 

 as follows, the conditions as far as they can be determined being about equal : —
