DEPTH OF PLOUGHING SOD TO BE SOWN TO WHEAT. 



There has not been time to get results on this part of the experiment, as the first 

 grass seed was sown in 1911 ; and, consequently, there was no sod to plough up the same 

 season. Sod has been ploughed, the various depths, in 1912, and the 1913 crop will 

 give the yields produced thereon. 



SUMMER-FALLOW TREATMENT. 



The plots on which this year's results are obtained, were summer-fallowed in 

 1911. With the exception of plots 11 and 13, they were ploughed on June 14, 1911. 

 Those getting a second ploughing, received it on September 28, 1911. The other 

 operations, during the summer, were according to the methods outlined below. Wheat 

 was sown on May 10, and, with the exception of plot 10, came up on May 19. On plot 

 10, it came up on May 21. All headed out on July 6, were ripe on August 26, cut on 

 August 28 and threshed on September 12.
