Box 2. Medium, slight check in J une ; the earliest to flower, and 
with the most abundant blooms, but flowers small. 
Box 3. Medium. Eise at the end of May, arrest in the begin 
ning of June. Less floriferous than 1, but broader in the leaf. 
Box 4. Low in May. Sudden rise in the early part of June 
maintained subsequently. Stouter stalks than in 3. 
Box 5. High degree of vigour, which increased in the early 
part of June, and subsequently slightly declined. Stoutest 
flower-stalks of all. 
Box 6. Maximum throughout May ; check at the end of the 
month, and throughout June.' 
All the plants showed the effects of drought, except 1 and 2 ; 
latterly but little difference could be detected between them. In 
no. 1 no relation between the growth of the plant and the fluctua- 
tions in temperature or rainfall was observed. In 2 a slight arrest 
in the middle of June, corresponding to the diminished rainfall, 
was noticed. In 3 a rise at the end ol May, in proportion to the 
increased rainfall, and a check at the beginning of June, in propor- 
tion to the diminished rainfall, were observed. In box 4 there was 
a rise at the beginning of June, corresponding to the rise in 
the rainfall, and a gradually increasing rise throughout June, 
corresponding to the rise in temperature. In box 5 there was a 
slight decline in vigour towards the end of June, in proportion 
to the diminished rain, and in box 6 a decline towards the end 
of May, corresponding to the decline in the rainfall.

Box 1. Minimum, progress slight in the end of June, followed 
by a check, plants healthy. Average height, July 1, 10 inches. 
Box 2. Uniformly low in vigour. 
Box 3. Uniform medium. 
Box 4. Began low, rose in the middle of May to medium. Ulti- 
mately less healthy than 3. 
Box 5. High ; rose to maximum at the end of May. Average 
height, July 1, 9 inches. 
Box 6. Maximum in May ; slight arrest at the end of the month. 
The plants in boxes 1 and 2 were yellow-green, those in 4, 5 
and 6 bluish green. All, except those in 1 and 2, flagged, those in 
5 the most so (from drought). Those stalks which became 
exposed to the light assumed a purple colour. 
In the plants in box 1 a slight rise took place at the end of J une
