The plots that were ploughed twice were uniformly two days later than those 

 that were ploughed only once. Plots 16 and 17 considered by themselves seem to show 

 a decided advantage for soil packing. When, however, it is remembered that all idiots 

 except plot 17 were pa,cbed, and that plot 12 received identical treatment with plot 

 16, this result is not so clear. A note on the condition of the crop shows that plot 

 13, ploughed in July, was much weedier than the others. 



STLBBLE TREATMENT. 



The plots on which this experiment was conditcted grew wheat in 1912. The 

 experimental treatment of the stubble land, as describes! below, was performed in the 

 fall of 1912 and spring of 1913. Plots 1 to 10 were sown to w^'.eat April 17, at the rate 

 of Ig bushels per acre. Plots 2 and 3 came up ^fay 2, plo', 5 Hay 3, and the others 

 May 4. Plots 1, 2, 3, 5 and 10 headed out June 27, plote 4, 6, 7, and 9 June 28 and 

 plot 8 June 29. All ripened August 5, were cut August j, and threshed August 29. 



Plots 11 t« 13 were sown tt> oats May 7. All came up May 23, headed out July 9, 

 ripened August 14, were cut August 14 and threshed September 2.
