the soil of all the pots in the experiment. When the crops 
were harvested there was a large number of tubercles on the 
roots in all the pots. 
The samples were taken November 10, 1899. ‘The entire 
crop of seed from each pot was taken asa sample. ‘The seeds 
were well dried when harvested; they were shelled from the 
pods and put into numbered bags.

The growth on the different pots was quite irregular, owing 
to the failure of many seeds to germinate. ‘The number of 
plants per pot, of fairly uniform size and vigorous growth, 
varied from one to eight. ‘This has made it advisable to omit 
from the averages results from pots showing abnormal yields. 
Omitting these it will be seen from the data in Table 51 that
