minimum, the plants in the unmanured box at the same time 
rising to maximum. In Trifolium repens the growth was good 
throughout and without much fluctuation. InFlantago the growth, 
at first high, was subsequently checked. In Acliillea the same 
phenomena were observed as in the case of Lotus — high at first, 
declining to minimum after the cutting, at the same time that the 
plants in the unmanured box rose to a maximum. In Camm the 
growth was maximum to the last. 
It would thus appear that the mineral and nitrate was, on the 
whole, of most service to those plants with fleshy tap-roots {Lotm, 
Trefoils, Carum), or to those w4th a somewhat woody stock, like 
Acliillea, but of less service to the fibrous-rooted plants, as 
grasses. The very marked change from maximum to minimum in 
the case of Lotus and Acliillea would seem to. imply that the sea- 
son's growth was in a measure complete at the time of cutting, 
while in the unmanured boxes, on the other hand, growth went 
on more vigorously afterwards. It must be remarked that the 
flowering was more profuse in box 6, in the cases mentioned, 
than it was in box 1. 
Notes on the Condition of the Plants on Octoher IZth. 
After the herbage was cut in the beginning of July, the obser- 
vations were not carried on systematically till the time when the 
herbage was again cut in the middle of October. 
As the growth for the season, so far as the top is concerned, 
may be considered to have been completed at that time, it seems 
desirable to append a statement of the condition of the plants on 
that day. The general result is shown in a diagrammatic form in 
the Tables. 
i. Dactylis. 
Box 1 (Unmanured). The plants were at this time rather 
unhealthy — the leaves broad, but slightly injured by frost. The 
average height was 7 J inches, and there was but little tendency to 
flower. The plants in this box were, on the whole, rather better 
than in box 2. 
Box 2 (Mineral manures). The plants were of a yellowish 
colour, slightly injured by frost, the leaves narrower than No. 1, 
and the plants averaging about 6 inches, with little or no ten- 
dency to produce flowers. The plants in this bos were the least 
developed of any.
