Speaking first of the results of 1898, we have to state that the crop 
from the inoculated seed was in appearance much more luxuriant than 
that of the untreated seed. The weights taken at the close of the season 
show that the yield from the former was considerably heavier than that 
from the latter, again giving evidence of the marked beneficial influence 
exerted by Nitragin. The weights of the crops are tabulated as follows :

Our results with clover for 1899 consist solely of data obtained from 
the growth on areas left from the previous season, that is, on the second 
year’s growth, both the untreated and inoculated plants having survived 
the winter. Both series made excellent growth, but the plants from in- 
oculated seed were very much larger. On July 10th the experiment 
was closed, the accompanying photograph being taken before digging the 
plants. The data presented in the foregoing table show the most marked 
increase due to Nitragin yet observed, and indicate that the benefit due 
to this preparation is in all probability greater the second than the first 
year. This is no doubt due to its effect upon root development. The 
nodules on treated plants were larger and more numerous than on the 
untreated plants. The illustration serves very well to emphasize these 
data and to exhibit the more luxuriant growth of the inoculated plants. 
PEAS. 
The investigation with respect to the influence of Nitragin upon the 
growth of peas, was conducted as both pot and plot experiments in 1898. 
A tall growing variety of peas was selected, and the culture used was 
“ Pisum sativum.” The samples were collected when most of the pods 
were fully formed ; the plants, however, were still quite green and pos-
