previous year. In ld02 the plots were sown with oats and again A 

 gave the larger yield — the dift'erence being at the rate of 23 bushels 

 18 lbs. per acre. The following year, 1903, both plots were sown with 

 sugar beets, and again an increased yield on A was obtained. 



Series II: — The only ditîerence in plan from Series I lies in the 

 fact that in the preceding experiments the clover was so^vn 'alone, 

 whereas in this second series grain (oats) was sown with the clover, 

 on Plot A. Thus, both plots were made to carry the same crops 

 throughout the experiment, 'and therefore any difference in favour of the 

 ■clover bearing plot cannot be accounted for by it having borne 'one 

 less harvest crop than B ■ — the non-clover plot. This series was started 

 in 1901, A being sown witli oats and clover; B with oats alone. In 

 1902 Indian corn was sown on both plots and the returns showed 5 

 tons 800 lbs. more fodder than Plot A. Potatoes followed the corn 

 (1903), the yield of A exceeding that of Plot B by 47 bushels 20 lbs. 

 Barley was sown the ensuing year (1904) and A yielding 6 bushels 20 

 lbs. 'more than B. These results will, perhaps, be somewhat more 

 evident if arranoed in tabular form.
