The next table gives the average yield for the plants in the rows of 

 ' Ne Plus Ultra ' on the ground which had been fallowed : —

In this series there is on an average a decrease of 3 per cent, in the 

 weight of pods produced by each plant from the inoculated seed, while 

 the weight of peas is on an average the same. In each series of weigh- 

 ings four rows show a decreased yield from the inoculated seed. This 

 compared with five decreased yields from inoculated seeds when the 

 totals are compared, though the percentage decreases in the total yields 

 are, for the most part, smaller than decreases shown when the average 

 yields of the plants are considered. 



There remain the rows of 1 Maincrop ' on the fallowed land, and the 

 following table shows the average yield for each plant from these : —

With this variety for the first time we find a considerable increase 

 in the average yield from the inoculated plants compared with the
