The principal points sb own in the Table are these: — Mineral 
manures alone were of little or no use to the plant, the general 
vigour being often less than in the unmaniired box. 
The ammonia salts alone produced, on the whole, the most vigor- 
ous development, though this declined somewhat towards the end of 
the season. 
The nitrate of soda produced a uniformly medium effect. 
The mineral and ammonia manures secured the highest develop- 
ment next to that produced by the ammonia salts alone. 
The mineral and nitrate induced a high medium development. 
Considerable inequality of growth was observable among the in- 
dividual plants in boxes 2, 4, and 6 respectively. 
The colour of the foliage varied at different times, but was always 
palest in boxes 1 and 2. All were about equal in point of date of 
maturity, except the plants in boxes 1 and 2, which were later than 
the others.
