 seed, 35. 



Here the difference in the nuinher of plants in the rows of ' Maincrop ' 

 interferes with the exact comparison between the two plots, and the total 

 decrease in the crop shown by the table is too great. Every variety, 

 however, showed a diminished yield from the inoculated plot, and 

 evidently here inoculation was rather detrimental than the reverse.

Extraordinary variations are apparent in the results from these plots, 

 due in the main at least to variations in the numbers of plants in the 

 rows. 'We have not the figures for the varieties ' Duke of Albany ' and 

 ' Telegraph,' owing to an accident, but the number of plants of 1 Ne Plus 

 Ultra ' in the non-inoculated row was 24 ; in the inoculated, 38 ; of 1 Main- 

 crop ' in the non-inoculated row, 33 ; in the inoculated row, 24. 



As figures stand it would appear that if lime were added to the soil 

 then the inoculation would have been very beneficial (but there are con- 

 tradictory figures as well). If this be true then we should find that 

 inoculation was beneficial also in the next pair of plots, where also lime 

 was added.
