October and November. To be brief there is a warm dry 
period during February and March, a hotter but moister 
one during April and May, followed by seven to eight months 
of rainy weather when the temperature is comparatively low 
and humidity high. We can therefore speak of one hot 
dry and hot moist season of four months and a cooler moist 
period for the rest of the year. (See plates XXVI. to 
XXVIII.) 
The Climate at Hakgala. 
Hakgala is 5,581 feet above sea level. The climate resem¬ 
bles that atPeradeniya in having both monsoons, but differs 
from it in so far that ( a ) there is a heavier rainfall, mainly 
from October to December ; (5) the average yearly tempera¬ 
ture is 15° F. lower than at Peradeniya ; and (c) the yearly 
humidity is 9 degrees higher. The periodicity of the 
climate is almost the same as at Peradeniya, but the air is 
cooler, the rainfall heavier, and the atmosphere always more 
moist. (See plates XXVI. to XXVIII.) 
The Climate in Colombo, 
Colombo is at sea level, and the climatic periodicity 
prevailing there is almost the same as at Peradeniya. 
Compared with Peradeniya the annual rainfall is nearly 
the same ; the temperature is on an average 5° F. higher 
and the air more moist. (See plates XXVI. to XXVIII.) 
The Climate at Badulla. 
The climate at this place is quite different from that at 
Peradeniya. The rains fall mainly in the north-east mon¬ 
soon, and the annual rainfall is about 5 inches less than at 
Peradeniya. The temperature is more regular, but usually 
2° F. lower than at Peradeniya. The curves show that the 
dry hot period is from June to September and that the rest 
of the year is relatively moist and cool. (See plates XXVI. 
to XXVIII.) 
The Climate at Mannar, 
The differences between the climate at Mannar and 
Peradeniya are obvious from the various curves, and may be
