choose, nor yet in the case of the poor soil. Similarly with 
the tares ; at first the treated seed plants looked the better, 
but all differences had passed away by the end of July. The 
irregularities in the clover plant prevented clear deductions 
being made, but a first crop was cut on August 23, and the 
plants are being kept on for a second year’s observations. The 
germination with soy bean was so poor that no value could be 
attached to this series, but melilotus, grown in pots, was generally 
better from treated than from untreated seed. This latter was, 
indeed, the only crop in which an advantage was distinctly 
seen as the result of the treatment, and this was brought out in 
photographs taken of the crops before cutting. In regard to 
the plants grown in the open, melilotus was, again, the only 
one to show anything in favour of the treatment. The respec- 
tive crops were cut and harvested when ready, and the weights 
obtained. In the case of the pots the crop weights are given 
in grammes, and with the plots in the open in pounds and 
ounces. Records were also kept of the number of pods, grains, 
&c. ; but the following figures will suffice to convey an idea of 
such differences as were brought out. The mean is taken of 
the duplicate pots in each case.
