The plants in boxes 4, 5, and 6 were the earliest to show 
flowers, while those in box 5, mineral and ammonia, produced 
the greatest number of flowers. The ripening of the seed was 
latest in boxes 1 and 6.

Boots. The lowest degree of vigour of the roots was shown in 
box 6, at the same time that the plant was also relatively defici- 
ent in vigour. It may be surmised that had the roots been 
examined in June, when the plants were comparatively highly 
developed, they would have been found correspondingly developed. 
This is borne out by the circumstance that in box 2 the roots in 
April 1871 were at the maximum, while the plant was also high. 
Ammonia salts also induced a high medium root-growth, which 
was somewhat less in the case of the nitrate of soda. 
In the mineral and ammonia box root-development was high 
as well as that of the plant, while in the mineral and nitrate, as 
before stated, the root-growth was relatively deficient.
