the average yields on the pots of different groups were nearly 
the same. ‘The results obtained in the total crop seem to be 
little influenced by the amount of nitrogen in the fertilizer. 
This was in accord with results obtained with this crop in field 
experiments with nitrogenous fertilizers. 
There was but little variation in the percentage of nitrogen 
in the crops from the different pots. The average percentage 
where the largest (full) ration of nitrogen was used was only 
two-tenths of one per cent. above what was obtained where no 
nitrogen was used. 
These results are in striking contrast with those obtained in 
the experiment with orchard grass (first crop) and with Hun- 
garian grass. With these latter crops the percentage of nitro- 
gen was sometimes twice as large where the larger amounts of 
nitrogen were used as where only mineral fertilizers were used. 
EXPERIMENT WITH SOY BEANS, I9OO. 
The experiment of 1899 with this crop was repeated in 1900 
in the same pots but with a new lot of soil. In this case the 
soil was taken from field plots which had produced soy beans 
for five years without the application of nitrogenous fertilizers. 
A large number of tubercles was found on the roots when the 
crops were harvested. 
The samples were taken October 10, 1900. All the seeds 
from a pot were taken fora sample. ‘The seeds dried on the 
stalks before harvesting. The growth was much smaller on 
the pots as a whole than in the experiment of 1899. Notes 
taken late in the period of growth show that there was little 
difference in the appearance of the plants on the different 
groups of pots. There were six plants in each pot, and the 
general conditions of growth were nearly the same, except that 
the plants were somewhat smaller where no nitrogen was used. 
The range in the average percentages of nitrogen in the 
crops from pots of the different groups was from 6.28 per cent. 
to 6.40 per cent. The differences between the percentages of 
nitrogen in the crops from pots in the same group, which, of 
course, were all fertilized alike, were often greater than those 
between the averages for the groups of pots receiving varying 
quantities of nitrogen in the fertilizer. The results of this 
experiment would seem to indicate that with soy beans no
