SOIL PACKERS. 



Packing for Wheat sown on Summer- falloiv. 



The plots for this experiment were all summer-fallowed in 1911. Plots 15 to 20 

 were packed, after ploughing, as described in the following table. The ploughing was 

 all done on June 14. Packing and other spring work was done on May 10 and 11. 

 All plots were sown to wheat on May 10, ail came up on May 19 ; plots 2, 6, 7, 8, 9, 10, 

 18, 19 and 25 headed out on July 4, plots 3, 4, 11, 12, 13, 14, 15, 16, 17 and 21 headed 

 out on July 6; plots 1, 22, 23 and 24 headed out on July 8. All ripened on August
