the conclusions to be drawn from them. ' This was very unlikely to be the 

 case, for on account of the arrangement of the plots (see fig. 37, p. 287) 

 local conditions would not be very liable to affect the plots receiving 

 inoculated seed adversely while the corresponding plots receiving untreated 

 seed remained uninfluenced. 



In an experiment such as this, planned to test what is likely to 

 happen in a garden under ordinary conditions, the only basis of calculation 

 which can properly be adopted must be to take the crops as they actually 

 occur. The question of the variation in the number of plants does not, 

 therefore, affect the result from a practical garden point of view, when it is 

 borne in mind that one of a pair of plots, was, apparently, no more 

 exposed to adverse conditions than the other, and that each of the pair 

 received the same weight of seed, but from a scientific standpoint the 

 question is not without interest. 



In order to test the question as to how far the varying number of 

 plants in the corresponding plots affected the general results, and 

 especially the question of the efficacy or otherwise of inoculation, we may 

 ascertain the average yield of the plants on each of the corresponding 

 plots and compare these yields. 



Unfortunately, the figures relating to the number cf plants of the 

 varieties ' Duke of Albany ' and of ' Telegraph ' in the rows were acci- 

 dentally lost, but we have those relating to ' Ne Plus Ultra ' and to 

 ' Maincrop ' and it was in the last named that the greatest amount of 

 variation in the number of plants in the rows was noticed (see previous 

 Report). We are thus able to compare the average yields of plants from 

 forty-eight rows distributed equally over the several plots, half having 

 been raised from inoculated seed and half from uninoculated. 



The number of plants given in the rows in the following tables means 

 the number that came to maturity in each case. The treatment received 

 by the respective plots has been fully dealt with in the former Report. 



We may take the results obtained on the cultivated ground with 

 < Ne Plus Ultra ' first :—
