 different parts of the Garden at various times during the month, 

 and no instance of new growth was observed, except a few 

 species, such as Saraca indica, on which new growth is to be 

 found at almost all times of the year, so that the absence of 

 names for October means that there was no new growth or 

 very little. 



The total number of species showing new growth in each 

 month recorded is as follows : — 



The following is a record of the average rainfall for the years 

 1884-1906 inclusive at Peradeniya : — 



Average number of rainy days in each month for the same 

 period — 



The outstanding fact with regard to this record is that the 

 month of February, the driest month of the whole year, had 

 the largest number of growing species ; September, another 

 rather dry month, had a considerable number ; November 

 and July, wet months, had very few growing species ; while 

 October, the month with the highest rainfall, had the fewest 

 of aU. 



There thus seems to be a rather surprising correlation 

 between amount of growth and lack of rain. There is proba- 

 bly some deduction to be made from the number recorded 

 in December, 1905. This was the first time of making the 

 record, and the writer had scarcely appreciated the limits of the
