308 -Mini : lpplicatioh of the theory of 



30 thai the total yearly rainfall of about 80 inches is well dis- 

 bributed. The temperature in 1906 reached a lower limit of 

 about 14 C. on a few nights in January and an upper limit 

 of about 33° C. on some days in March. In general, however — 

 and this is especially true of the months of June and July 

 during the South -West monsoon — the temperature varies 

 very much less than this. In these months the range is 

 usually from 20° to 26° C. during the twenty- four hours. 



Hakgula is at an elevation of 5,600 feet and has a slightly 

 greater rainfall than Peradeniya. The average rainfall for the 

 last twenty-one years is 91 70 inches. This rainfall is well dis- 

 tributed throughout the year, though it receives more rain in 

 the North-East monsoon and less in the South-West than Pera- 

 deniya. It differs from Peradeniya chiefly in the temperature. 

 The lowest recorded temperature is 29 c O, and in February the 

 temperature not infrequently approaches within 4° or 5 C. 

 of freezing point. From March to May an upper limit of about 

 22° C. is sometimes reached, but in the South-West mon- 

 soon the temperature varies. very little, the range being 

 usually from 13° to 17° 0. during the 24 hours. The temper- 

 ature during my observations on July 9 — 11 varied within 

 these limits. It also differs from Peradeniya in the much 

 greater prevalence of mist. 



\ii'intdhapura, elevation about 300 feet, has an average 

 annual rainfall of 542 inches. This falls chiefly in the months 

 "t October, November, and December in the North-East mon- 



ioon. These I hire monl hfl have an a \ erage rainfall of 8*6, 10*6, 

 and 0*3 inches respectively. 7*3 inches fall in April, so that the 

 remaining eight months have a very small rainfall. June ami 

 ■ lul\ in ili, South-West monsoon are the driest months of the 



.i ;n ha \ mil' respectively an average rainfall of 1*4 inch and II 



mch. The lowest recorded temperature is 13*4° 0. and the 



39*4° C, but of course the temperature very rarely 



varies a* much as tins. For the months () f dune and duly the 

 n in. i \imuni temperature is 32*8 < '. and '.va-'A < '. respective- 

 ly and the mean minimum temperature is 21 I and 24*3 C.
