Nitrate of soda seems to have induced, in the early part of 
the season, the most robust and vigorous growth. It was also 
remarked that the maturity of the plant was comparatively early 
in this box.

The plants in the box with the mixed ammonia and mineral salts 
were also well developed throughout, and at the end of the season

Mineral and nitrate induced the growth of good average plants, 
with comparatively little fluctuation throughout. 
Mowers were produced in about the same numbers in boxes 4, 5, 
and G, and much less abundantly in boxes i to 3. 
The roots in the unmanured box, when examined in April 1871 , 
showed a high degree of vigour, those in the second box (min. man.)

in the fourth (nitrate of soda) highest of all ; in the fifth (mineral
